4 R 1. GENERAL NOTES Fox up ventilation units are built in accordance with the latest technological standards and acknowledged safety regulations. Installation and maintenance on the ventilation unit should only be carried out by specially trained personal in accordance with the regulations on occupational safety and accident prevention. The electrical connection must be carried out according the applicable national regulation. During installation and maintenance work, all poles must be disconnected from the mains with a contact gap of at least 3 mm. Disconnections must be fixed in the open position!! The unit may only be used for its intended purpose. Improper use, installation or maintenance work carried out incorrectly and structural modifications may affect the function and safety of the ventilation unit. In this case the warranty claims will not be valid. Read these instructions carefully before beginning any installation or maintenance work and follow the advice given on installation and maintenance. Before installing the unit, check that the delivery is complete and intact, and contact us, at the address below, if any parts are missing or damaged. Intended use Fox up ventilation units with heat recovery are designed for controlled room ventilation. The units should only be used to deliver air. The delivery of aggressive, flammable or dust-containing media is not permitted. Never operate the unit without the filter in place. The connection of ventilation pipes from other ventilation systems is not permitted. Fox up ventilation units are not suitable for construction drying, and should only be used once construction work has been finished. Operating the unit in conjunction with heat-producing appliances may require additional safety devices. Relevant information is available from a regionally qualified chimney sweep. Placing the unit Fox up ventilation units may only be installed and operated indoors. When selecting a site, please make sure that the unit is accessible for service and maintenance. The unit must not be installed close to flammable liquids or gases. A mains supply (230 V/50 Hz) is required to operate the unit. Installation When installing the unit, please observe the recognized codes of practice with regard to unit installation, electrical work, fire protection, etc., as well as the standards for the ventilation of residential buildings. 2

5 2. PRODUCTINFORMATION 2.1 Mode of operation The Fox up ventilation unit is a decentralized ventilation system for a controlled room ventilation with heat recovery. The use of several units in pairs allows entire housing units / buildings to be ventilated. If operated with heat recovery, the ventilation unit works in 2 prefixed time intervals. In the first interval (extraction phase), the used air in the room is sucked into the ventilation unit by the fan and carried to the outside. During this process, the air flows through the ceramic heat accumulator inside the ventilation unit, which extracts the heat from the air and stores it. In the second interval (delivery phase), fresh outside air is sucked in via the ventilation unit s exterior opening. It passes through the unit, and is heated by the heat accumulator before entering the room. In this way, up to 90% of the heat contained in the extracted air can be transferred to the fresh air fed into the room. The principle of recharging and discharging a heat accumulator is referred as regenerative heat transfer. EN When a single unit is used, an overpressure (delivery phase) or under pressure (extraction phase) is created in the room being ventilated, this depends on the operating phase. To guarantee a balance between the volumes of air delivered and extracted, it is recommended that Fox up units be used in pairs. The control of the ventilation units allows up to three pairs of units to be operated simultaneously. 2.2 Planning notes Before installing Fox up ventilation units, a ventilation plan should be made. This specifies the number of ventilation units, their locations, the ventilation principle (transverse ventilation, single-room ventilation). Also it specifies the position and number of the associated electronic control systems. Fox up ventilation units allow the following variations in ventilation: Single-room ventilation with one ventilation unit, alternating between delivery and extraction modes with heat recovery at intervals, alternatively delivery* or extraction* mode (* depending on the electrical connection, see page 9). Transverse ventilation with ventilation units operating in pairs, alternating between delivery and extraction modes with heat recovery. While one unit of a pair runs in delivery mode, the designated second unit operates in extraction mode. The air direction of both units swapping in the next interval, alternatively delivery* or extraction* mode (* depending on the electrical connection, see page 9). Where possible, Fox up ventilation units should be used in pairs see Mode of operation. The pairs of units can be used in one or multiple rooms. It can also be arranged across more than one floor within a unit. The air must be free to flow between the rooms which needs to be ventilated by means of sufficient dimensioned overflow openings (e.g. door air grilles or shortened door leaves). To prevent that odors are being transferred to other rooms (delivery phase of ventilation unit), two units operating in a push-pull arrangement should always be installed when airing/ventilating kitchens, bathrooms or toilets with windows. Fox up units should not be used in internal, windowless exhaust-air rooms such as kitchens, bathrooms and toilets. It is not permissible to connect the units to a shaft or pipe. In this case, the use of an exhaust fan in accordance with the national norm is recommended, e.g. the BRAVO fan type. The units are also unable to be installed in cellar rooms with light shafts, since it is possibility that the outgoing air is recirculated. When the units are installed on a façade there needs to be a minimum distance of 1.2 m between individual units in order to avoid recirculation. We recommend not using the unit in a location on the building that is exposed to the wind with a average wind speed of more then 5 m/s. To prevent the ventilation units from causing inconvenience draughts, they should not be positioned directly next to people who are a longer time in one place (seating, beds). Make sure that the flow of air into the room is not obstructed by furniture or curtains 3

6 R 3. DELIVERY UNITS / DELIVERY CONTENTS A complete Fox up ventilation unit consists of an EPS wall duct and a fan unit for insertion into the wall duct. The fan unit consists of a reversible fan (12 V/DC) and a ceramic heat accumulator for heat recovery. Air is fed into the room through a design plate with filter insert, and carried to the outside through a weatherproof protective hood.

SELECTING INSTALLATION SITE When selecting the installation position, pay attention to the outer wall of the building, the units needs to be positioned esthetical correct in the building façade. For example: the units should be installed at the same height as the windows and at equal distances from windows. The outside or room-side air inlet/outlet opening is recommended at a minimum distance of 150 to 200 mm from adjacent façade components and room corners! Fox up ventilation units should be installed at a height of 1.6 to 1.8 m above the finished floor level, and the room-side air inlet/outlet opening must not be covered by furniture or curtains. 6. INSTALLATION OF WALL DUCT EPS pipe wall duct Inner ø 153, outer ø 198 mm, built-in gradient to outside (condensate drainage) Wall ducts are available in two different lengths for Fox up ventilation units: Pipe length 500 mm: Fox up shell set 500 mm, item no or Pipe length 1000 mm: Fox up shell set 1000 mm, item no or The delivery units Fox up-gp-design and Fox up-ep-design are supplied as standard with 500 mm wall ducts, the wall ducts are manufactured with a built-in gradient to the outside for condensate drainage (observe marking of outside, see fig. above). 6

9 6.1 Tap hole drilling for wall duct Create a hole with a diameter of 200 mm. Feed the fan connecting lead (min. 3 x 0.25 mm2) into the wall duct. The fan connecting lead must be perpendicular to the axe of the wall duct. EN 6.2 Installation of wall ducts Determine the overall thickness of the wall structure from the dimensions of: - The work measurement (D) - The outside (E) (e.g. heat insulation + plaster) - The inside (X) (e.g. plaster + tiles). - The minimal length might never be shorter then 240 mm Slide the wall duct into the wall opening, observing the gradient to the outside / the room-side marking of the wall duct. Allow the wall duct to stand perpendicular on the both room and façade sides in accordance with the above calculation. Attention: To ensure good movement of the fan / heat unit in the wall duct, deformations of the wall duct due to external pressure/tension should be avoided! 7

10 R 6.3 Wall duct for insertion of connecting lead of ventilation unit Feed the electric connecting lead of the ventilation unit (see view from room side) into the wall duct. Check the correct position of the wall duct (overhangs outside / inside) and close the openings of the wall duct with the protective covers. Finally, fill the cavities (if any) between the wall opening and the wall duct with non-pressurized expanding foam. 7. INSTALLATION OF ELECTRONIC CONTROL SYSTEM The electronic control system of Fox up ventilation units is designed to be installed in a double hollow cavity flush-mounted box. It can be used to control up to six Fox up ventilation units. The electronic control system is to be connected as stationary equipment with fixed wiring. See page 9 for electrical connection diagram. The supply voltage of the electronic control system is 230 V/50 Hz. A light-plastic sheathed cable 3 x 1.5 mm2 (e.g. NYM-J 3 x 1.5 mm2) is recommended as an incoming line. The ventilation units are supplied by 12 V DC in combination with a PWM controlling signal. Therefore, the ventilation units should not under any circumstances be connected to the 230 V mains voltage of the electronic control system. A light-plastic sheathed cable 3 x 0.25 mm2 (e.g. LiYY 3 x 0.25 mm2) is recommended as a control line for the ventilation units with a maximum length of 10m. 8

11 8. ELECTRICAL CONNECTION OF ELECTRONIC CONTROL SYSTEM / VENTILATION UNIT The electrical connection must be carried out according the local applicable standard. During installation and maintenance work, all poles must be disconnected from the mains with a contact gap of at least 3 mm. Disconnections must be immobilised in the open position! Connecting the electronic control system: EN Connecting a single unit: A single ventilation unit is connected to the Unit 1 or Unit 2 plug-in connector as shown in the figure on the left. When connected to the Unit 1 plug-in connector, the unit can be used in summer mode (see Ventilation mode page 16) as a delivery unit. When connected to the Unit 2 plug-in connector, the unit can be used in summer mode as an extraction unit. Connecting several units: Several units may be connected in pairs to the plug-in connectors Unit 1 Unit 2, Unit 3 Unit 4, Unit 5 Unit 6; when used in pairs. One of the units in the pair operates in delivery mode, and the second unit operates in extraction mode, with the air direction of both units swapping in the next interval. 8.1 Connecting ventilation unit(s) electronic control system Fox up ventilation units are connected to the electronic control system via a plug-in connector supplied with the ventilation units as shown above. Please observe polarity of delivery/extraction units (see fig. above)! 9

12 R 8.2 Electrical connection of external control elements The operating mode of Fox up ventilation units is set to user-dependently via the control panel of the electronic control system. Different operating variants can be selected with different power stages. By connecting optional external control elements, a time- or moisture-dependent unit mode can also be activated. External control elements are connected as shown above via the external inputs connector to the electronic control system of the ventilation units. The function of the unit when controlled externally is described from page 19 of these instructions. Connecting external control elements A data line (e.g. 2 x 2 x 0.6 (e.g. J-Y(ST)Y) is recommended for connecting external control inputs (floating contacts). 10

13 9. INSTALLATION 9.1 Installation of fan unit After the electrical connection has been made, the fan unit, consisting of the heat accumulator and fan, is inserted into the wall duct: EN Carefully slide the fan unit (fan towards façade) into the wall duct, making sure that the fan s connecting lead is not trapped / damaged. The strap on the heat accumulator allows the fan unit to be aligned during installation and removed from the wall duct for maintenance purposes. Next, connect the plug-in connector between the connecting leads of the ventilation unit and control unit. 9.2 Final assembly Once the insulation and plastering work has been completed, the wall duct must be adapted to the dimensions of the finished wall by being cut with a Stanley knife or hot wire flush with the wall on both room and façade sides. Next install the support frame for the internal plate (room side) and the weatherproof protective hood (façade side) of the ventilation unit using the mounting materials which are supplied with the ventilation unit. 11

14 R To prevent water from entering the wall opening, the façade-side transition between the wall duct and the support frame for the weatherproof protective hood must be sealed all round with silicone or some other suitable sealant! Slide the filter insert (1) supplied with the ventilation unit into the wall duct and close the inner plate (2) of the ventilation unit (magnetic catch). Finally, install the unit s façade-side weatherproof protective hood (3). The hood is clipped onto a lug on the top of the support frame and attached to the bottom of the support frame using the fastening screw as supplied (4). 9.3 Functional test of ventilation unit(s) Once installed, the function of the unit(s) must be checked. Before carrying out the check, make sure that the air passages of the ventilation unit(s) are free from assembly residues / foreign bodies and that all electrical work was carried out and completed in a technically correct manner! After switching on the power supply (generally via the electrical installation s automatic circuit-breakers), the ventilation unit can be started using the electronic control system s control panel. At start-up, check all the unit functions as described at page 18 of the operating instructions, making sure that the fan motor is running quietly and smoothly. Any malfunctions or faults found in the ventilation unit must be corrected before the unit is finally put into operation. Possible causes of faults and their rectification are described in the section entitled Malfunctions (see page 22). Document the properly performed installation / functional testing of the ventilation unit(s) in the start-up report on page 13 of these installation instructions. 12

Please read these operating instructions carefully before using the unit, and follow the instructions during installation and during maintaining the unit. The operator of the ventilation unit is responsible for the condition and proper operation of the unit, with due regard for the aforesaid instructions. Improper use, incorrectly carried out repair or maintenance work and structural changes may adversely affect the function and safety of the unit and invalidate any warranty claims. Installation and work on the ventilation unit should only be carried out by specially trained staff in accordance with the regulations on occupational safety and accident prevention. Fox up ventilation units with heat recovery are designed for the airing and ventilation of one or more rooms. The units should only be used to deliver air. The delivery of aggressive, flammable or dust-laden media is not permitted. Never operate the unit without the filter inserted. The connection of ventilation pipes / connection to other ventilation systems is not permitted. Fox up ventilation units are not suitable for construction drying, and should only be used once construction work has finished. Operating the unit in conjunction with heat-producing appliances may require additional safety devices (Fire Regulations). Relevant information is available from your local chimney sweep. Prerequisites for optimal ventilation: 1. Where possible, keep doors and windows in the rooms being ventilated closed. 2. If several units are operated, overflow openings are to be provided between the rooms being ventilated (shortening of door leaves, installation of door air grilles). 3. All ventilation units should be operated simultaneously in a ventilation setting as equal as possible. 14

17 2. UNIT DESCRIPTION The Fox up ventilation unit is a decentralized ventilation system for controlled room ventilation with heat recovery. The use of several units in pairs allows entire housing units / buildings to be ventilated. The ventilation unit consists of an EPS wall duct that can be cut to length for wall thicknesses up to 500 m (alternatively 1000 mm) and a fan unit inserted into the wall duct. The fan unit consists of a reversible van (12 V/DC) and a ceramic heat accumulator for heat recovery. Air is fed into the room through a white, powder-coated design plate with a filter insert (filter class G2), and is carried to the outside through a white, powder-coated weatherproof protective hood. The unit is operated via the control panel of a wired electronic control system for flush-mounted fitting, and up to six ventilation units (3 x delivery, 3 x extraction) can be controlled by the electronic control system.

18 R 3. SETTINGS FOR VENTILATION MODE 3.1 Settings for ventilation mode The operating variants of Fox up ventilation units are set using the control panel of the electronic control system of the ventilation units. Two basic functions with different fan powers can be set : Summer mode function > Winter mode function > 1. Summer mode function (delivery or extraction mode without heat recovery): In this setting, the ventilation unit(s) work constantly in delivery* or extraction* mode, without heat recovery. *The operating mode is defined by the electrical connection; the unit can be connected to the electronic control system as a delivery or extraction unit (see Electrical connection page 9) 2. Winter mode function (delivery and extraction mode with heat recovery): The ventilation unit(s) work alternately in 2 set time intervals. In the first interval (extraction phase), the used air in the room is sucked into the ventilation unit and pushed to the outside. During this process, the air flows through the ceramic heat accumulator inside the ventilation unit, which extracts the heat from the air and stores it. In the second interval (delivery phase), fresh outside air is sucked into the ventilation unit. It passes through the unit, and is heated by the heat accumulator before entering the room. If the Fox up ventilation units are used in pairs, the units in a pair work in opposite directions, i.e. the first unit in delivery mode and the Fox up ventilation system with 3 delivery and 3 extraction units: 16

19 3.2 Minimum ventilation option To guarantee a permanent minimum ventilation, there is the option with Fox up ventilation units of setting a constant ventilation mode at a minimum power stage. Depending on the setting, the ventilation unit(s) work in summer or winter mode. It is not possible to switch off the unit using the electronic control system s control panel. The minimum ventilation is activated / deactivated by re-plugging a jumper on the back of the control panel of the electronic control system. To activate the minimum ventilation, the control panel of the electronic control system must be detached (carefully remove control panel), and the minimum ventilation is activated on the disconnected control panel as described below: EN Attention: Before changing the jumper position, all poles of the power supply to the ventilation unit must be disconnected. Disconnections must be immobilised in the open position! < ---- alternative ---> If the jumper on the back of the control panel is plugged in, the ventilation unit can be switched off using the down arrow key (see fig. page 18). Ventilation is interrupted, and the unit off signal lamp (see fig. page 18) lights up. If the jumper on the back of the control panel has been removed or is only plugged into one pin, minimum ventilation is activated. The ventilation unit is not completely switched off using the down arrow key (see fig. page 18), but runs continuously at a minimum power stage. The activated minimum ventilation is signaled by the pulsing unit off signal lamp (see fig. page 18). 17

20 R 4. OPERATING AND DISPLAY ELEMENTS OF ELECTRONIC CONTROL SYSTEM Pressing this key sets the unit to power stage 1. Pressing this key again selects the next power stage up. Pressing this key switches the unit back to the next power stage down. If the unit is at power stage 1, pressing this key again switches the unit off or returns it to minimum ventilation1. 1 minimum ventilation option, see page 17. Pressing this key sets the unit to delivery or extraction mode2 without heat recovery (= summer mode). Summer mode automatically switches back to winter mode, 8 hours after being activated. Pressing this key again extends the summer mode by a further 8 hours. 2 depending on the electrical connection, see page 9. Pressing this key sets the unit to alternate delivery/extraction mode with heat recovery (winter mode). During the heating period, the device should be operated in this mode at all times. If this symbol lights up, the unit is at power stage 1. If this symbol lights up, the unit is at power stage 2. AIf this symbol lights up, the unit is at power stage 3. Power stage 3 automatically switches back to power stage 2 one hour after being activated. If this symbol is flashing, the external moisture mode has been activated3. 3 External moisture mode option, see page 19. If this indicator is permanently lit it indicates that the ventilation unit s filter insert is due for inspection / cleaning. The maintenance of the filter insert is described on page 20. If this indicator is flashing it indicates a functional fault on the electronic control system s control panel. The electronic control system or the control panel must be checked by a qualified electrician, see error messages page 22. If this indicator lights up, the unit has been switched off via the down arrow key. Ventilation can be switched on using the up arrow key. If this indicator is pulsing, the unit has been switched to the minimum ventilation power stage via the down arrow key (see page 17). The ventilation unit s power stage can be increased using the up arrow key. If this indicator is flashing, the unit has been switched off externally. For External off option, see page

21 5. EXTERNAL CONTROL INPUTS FOR ELECTRONIC CONTROL SYSTEM External input for moisture control To quickly remove moisture when ventilating rooms with a high moisture load, e.g. baths, showers, the output of the Fox up ventilation units can be increased depending on the moisture via an external hygrostat (= moisture-dependent switch). The switching point (= moisture level) for increasing the power is set on the hygrostat. If the set moisture level (recommended settings, summer: 65-80% RH, winter: 55-65% RH) is exceeded, the hygrostat activates power stage 3 in the ventilation unit. Hygrostats are connected to contacts 1 and 2 of the external inputs connector on the electronic control system of the ventilation unit as shown in the connection diagram on page 9. EN External moisture mode is displayed on the electronic control system s control panel by the flashing of the power level 3 signal lamp. If the power level is not changed manually on the control panel, the unit will continue to operate at the last active power stage after the external contact is switched off again. Power stage 3 of the externally activated moisture mode can be reduced to power stage 2 or 1 using the electronic control system s control panel. To ensure that the increased humidity is reduced, it is not possible to switch off the unit or return it to the minimum ventilation power stage. Unit off external input: To prevent moisture damage in your rooms, Fox up ventilation units have been designed for continuous ventilation. If the ventilation nevertheless has to be interrupted* at certain times, the ventilation unit can be switched off via an external switch / time switch. The switch / time switch is connected to contacts 3 and 4 of the external inputs connector on the electronic control system of the ventilation unit as shown in the connection diagram on page 9. A ventilation unit switched off externally* is indicated on the control panel of the electronic control system by the flashing of the OFF signal lamp. If the power level is not changed manually on the control panel, the unit will continue to operate at the last active power stage after the external contact is switched on again. A ventilation unit switched off externally* can be switched back on by pressing the power level up key on the control panel of the electronic control system. * The external switching off of the ventilation unit depends on the minimum ventilation jumper setting (see page 17). If minimum ventilation is activated, the operation of the system is not interrupted when switched off externally, but reduced to minimum ventilation. Minimum ventilation is displayed on the remote control by the pulsing of the OFF signal lamp. 19

22 R 6. CLEANING / MAINTENANCE OF THE VENTILATION UNIT The mechanical and electrical components of Fox up ventilation units are maintenance-free. Over time, however, airborne grease, particular matter, etc. cause the filter used in the unit to become dirty and leave a fine deposit on the fins of the heat accumulator and the blades of the fan. To guarantee the trouble-free operation of the ventilation unit, the filter insert, heat accumulator and fan must be checked and cleaned at regular intervals as described below. Dirt on the room- and/or façade-side air inlet/outlet openings (see ventilation unit components page 15) can be removed with a damp cloth. Never use detergents containing solvents, as these corrode the surfaces (plastic coating) of the air inlet/outlet openings! 6.1 Maintenance of the filter insert The filter used in the ventilation unit is monitored by an operating time meter in the electronic control system. After 3 months (2,750 hours operation), the filter change / fault signal lamp lights up permanently on the control panel of the electronic control system to indicate it is time to check the filter insert. Checking / cleaning of the filter insert is described below. Attention: Before all maintenance work, all poles of the power supply to the ventilation unit must be disconnected. Disconnections must be immobilized in the open position! To check the filter, the inner valve (1) must be removed. The valve is attached to its support frame with magnets and can easily be pulled out. After removing the inner valve, the filter insert (2) can be removed from the wall duct for checking. Remove filter insert If only slightly soiled (no or little dust deposits), the filter insert can be vacuumed or shaken. If there are significant dust deposits, the filter insert must be rinsed with warm water (max. 60 C). In the case of significant grease deposits, the filter insert can be cleaned in water mixed with detergent (degreaser). Any detergent residues must be completely rinsed off with clean water. Before putting the cleaned filter insert back into the ventilation unit, allow it to dry completely. A damp filter will gather dust straight away! Place the dried filter insert back into the wall duct of the ventilation unit and re-attach the ventilation unit s inner valve to its support frame. After checking / cleaning the filter insert and switching the power supply to the ventilation unit back on, the operating time meter that monitors the filter insert must be restarted. This is done via the control panel of the ventilation unit s electronic control system: 20

23 continued 6.1 Remove filter insert The operating time meter is restarted by jointly pressing the summer mode and winter mode keys and holding them down until the red filter change / fault LED goes out (approx. 5 seconds). Note: Filter monitoring can also be restarted as described above without prior notice from the filter change indicator, e.g. in connection with a regular overhaul. EN The filter inspection request is issued on a time-dependent basis after 3 months operation, regardless of how dirty the filter actually is. However, depending on the amount of dirt in the fresh air that is delivered, it may be appropriate to change the filter sooner. It is therefore recommended that the filter is checked in the first year after the ventilation unit is put into operation at three-month intervals. The inspection/cleaning interval must be reduced if the amount of dirt in the filter is clearly higher. 6.2 Maintenance of the heat accumulator / fan The heat accumulator and fan should only be checked / cleaned by someone with specialist knowledge. It is therefore recommended that the ventilation unit be checked once a year by an expert. During this inspection, the inner workings of the unit should be removed and checked for dirt / damage. If damage is found, the affected parts are to be replaced before the ventilation unit is put back into use. Spare/replacement parts are available from us at the address below. Unit components should only be dismantled by a qualified electrician with the ventilation unit disconnected from the mains (contact gap at least 3 mm). To check the heat accumulator and fan, the entire fan unit must be removed from the wall duct: Remove fan unit To remove the fan unit, the ventilation unit s inner plate (1) must be removed. The plate is attached to its support frame with magnets and can easily be pulled of. After removing the inner plate, the filter insert (2) and the fan unit (3) can be removed from the wall duct. If only slightly soiled, the heat accumulator / fan can be vacuumed. More significant accumulations of dirt on the fan can be removed with a small brush or a paintbrush. If the heat accumulator is heavily soiled, it must be removed from the fan unit and rinsed with water. 21

24 R Remove heat accumulator The heat accumulator is inserted inside the fan unit and can be removed from this for cleaning. Dirt on the heat accumulator can be removed with a rose (shower / bathtub) with warm water (max. 70 C). For heavy soiling / grease deposits, the heat accumulator can be cleaned in water mixed with detergent (degreaser). Any detergent residues must be completely rinsed off with clean water. After being cleaned, the heat accumulator must be completely dried (e.g. in the oven, max. 70 C). A damp heat accumulator will gather dust straight away! Place the dried heat accumulator back in the fan unit and position the complete fan unit back in the wall duct. To ensure the unit functions correctly, a complete functional test of the ventilation unit must be carried out after reinserting cleaned or repaired components and switching the power back on (see page 19). 7. ERROR MESSAGES / MALFUNCTIONS 7.1 Error messages Besides reporting that the filter needs checking, the filter change / fault signal lamp (see page 19) on the control panel of the ventilation unit s electronic control system also indicates a communication error between control unit and electronic control system. The communication error is reported by the repeated three-time flashing of the filter change / fault LED. If this message appears, the connection between the ventilation unit s control panel and the electronic control system must be checked by a qualified electrician. Attention: Before all maintenance work, all poles of the power supply to the ventilation unit must be disconnected. Disconnections must be immobilized in the open position! To check the connection between the control panel and the electronic control system, the control panel must be removed from the electronic control system. Then check the contacts of the connection for damage / foreign bodies / moisture. Foreign bodies must be carefully removed from the connection. Mechanically damaged components or components damaged by moisture must be replaced. Contact our spare/replacement parts department at the address below. To ensure the unit functions correctly, a complete functional test of the ventilation unit must be carried out after repairing components (see page 18). 22

30 R 1. ALLGEMEINE HINWEISE Die Fox up Lüftungsgeräte sind nach aktuellem Stand der Technik und den anerkannten sicherheitstechnischen Regeln gebaut. Montage- und Wartungsarbeiten am Lüftungsgerät dürfen nur durch ausgebildete Fachkräfte unter Einhaltung der Vorschriften zu Arbeitssicherheit und Unfallverhütung ausgeführt werden. Der elektrische Anschluß muß nach VDE 0100 durchgeführt werden. Bei Installation und Wartungsarbeiten muß eine allpolige Trennung vom Netz mit mindestens 3 mm Kontaktöffnungsweite vorgenommen werden, die Netztrennung ist gegen Wiedereinschalten zu sichern! Der Einsatz des Gerätes ist nur für den bestimmungsgemäßen Verwendungszweck zulässig, unsachgemäßer Gebrauch, mangelhaft ausgeführte Installations- bzw. Wartungsarbeiten sowie bauliche Veränderungen können Funktion und Sicherheit des Lüftungsgerätes beeinträchtigen und führen zum Erlöschen von Gewährleistungsansprüchen. Lesen Sie vor Beginn von Montage- / Wartungsarbeiten diese Anleitung sorgfältig durch und beachten Sie die zu Montage und Wartung angegebenen Hinweise. Überprüfen Sie vor Installation des Gerätes die Lieferung hinsichtlich Vollständigkeit und Unversehrtheit und wenden Sie sich bei fehlenden oder beschädigten Teilen direkt an unsere untenstehende Adresse. Verwendungszweck Fox up Lüftungsgeräte mit Wärmerückgewinnung sind zur kontrollierten Raumlüftung konzipiert. Die Geräte dürfen ausschließlich zur Förderung von Luft eingesetzt werden, die Förderung von aggres-siven, entzündlichen oder stark staubhaltigen Medien ist nicht zulässig. Betreiben Sie das Gerät nie ohne den im Gerät eingesetzten Filtereinsatz. Der Anschluß von Lüftungsleitungen anderer Lüftungs-systeme ist nicht zulässig. Fox up Lüftungsgeräte sind nicht zur Bautrocknung geeignet, der Betrieb der Geräte sollte erst nach Abschluß der Bautätigkeit erfolgen. Der Gerätebetrieb in Verbindung mit Feuerstätten erfordert gegebenenfalls zusätzliche Sicher-heitseinrichtungen (Feuerungsverordnung FeuV), entsprechende Informationen erhalten Sie beim regional zuständigen Schornsteinfeger. Gerätestandort Fox up Lüftungsgeräte dürfen nur im Gebäudeinneren montiert und betrieben werden, beachten Sie bei der Auswahl des Gerätestandortes, daß das Lüftungsgerät für Revisions- und Wartungsarbeiten zugänglich ist. Die Gerätemontage in Nähe zu entzündlichen Flüssigkeiten oder Gasen ist nicht zulässig. Zum Betrieb der Geräte ist ein Netzanschluß (230 V/50 Hz) erforderlich. Montage Beachten Sie bei Montage der Lüftungsgeräte die anerkannten Regeln der Technik (ARdT) bezüglich Geräteinstallation, Elektroarbeiten, Brandschutz etc; sowie die Vorgaben zur Lüftung von Wohn-räumen (DIN ). 28

31 2. FUNKTIONSWEISE / PLANUNGSHINWEISE 2.1 Funktionsweise Das Fox up Lüftungsgerät ist ein dezentrales Lüftungssystem zur kontrollierten Raumlüftung mit Wärmerückgewinnung. Der paarweise Einsatz mehrerer Geräte ermöglicht die Lüftung kompletter Wohneinheiten / Gebäude. Bei Betrieb mit Wärmerückgewinnung arbeitet das Lüftungsgerät in 2 einjustierten Zeitintervallen. Im ersten Intervall (Abluftphase) wird durch Abluftbetrieb des Ventilators die verbrauchte Raumluft in das Lüftungsgerät gesaugt und nach außen abgeführt. Die Luft durchströmt dabei den Keramik-Wärme-speicher im Inneren des Lüftungsgerätes der die Wärme der Raumluft aufnimmt und speichert. Im zweiten Intervall (Zuluftphase) wird frische Außenluft über die Außenöffnung des Lüftungsgerätes angesaugt, sie durchströmt das Gerät und wird vor Eintritt in den Raum durch den Wärmespeicher er-wärmt. Auf diese Weise können bis zu 90 % der in der Abluft enthaltenen Wärme an die dem Raum zugeführte Frischluft übergeben werden, das Prinzip des Be- und Entladens eines Wärmespeichers wird als regenerative Wärmeübertragung bezeichnet. Bei Betrieb eines Einzelgerätes entsteht im zu lüftenden Raum je nach Betriebsphase ein Überdruck (Zuluftphase) oder ein Unterdruck (Abluftphase), um ein ausgeglichenes Verhältnis zwischen Zu- und Abluftmenge zu gewährleisten wird der paarweise Einsatz der Fox up Geräte empfohlen. Die Steuerung der Lüftungsgeräte ermöglicht den gemeinsamen Betrieb von bis zu drei Gerätepaaren. DE 2.2 Planungshinweise Vor der Montage von Fox up Lüftungsgeräten sollte ein Lüftungskonzept erstellt werden aus dem die Anzahl der Lüftungsgeräte, deren Einbauort, das Lüftungsprinzip (Querlüftung, Einzelraumlüftung) und die Position / Anzahl der zugehörigen Steuerelektroniken zu entnehmen sind. Fox up Lüftungsgeräte ermöglichen folgende Lüftungsvarianten: Einzelraumlüftung mit einem Lüftungsgerät, im Intervall wechselnder Zu- / Abluftbetrieb mit Wärmerückgewinnung, alternativ Zu-* oder Abluftbetrieb* (* abhängig vom Elektroanschluß, sieheseite 35). Querlüftung mit paarweise betriebenen Lüftungsgeräten, im Intervall wechselnder Zu- / Abluftbetrieb mit Wärmerückgewinnung (während ein Gerät eines Gerätepaares im Zuluftbetrieb läuft, arbeitet das zugeordnete zweite Gerät im Abluftbetrieb, Luftrichtung beider Geräte im nächsten Intervall wechselnd), alternativ Zu-* oder Abluftbetrieb* (* abhängig vom Elektroanschluß, siehe Seite 35). Fox up Lüftungsgeräte sollten möglichst paarweise betrieben werden (siehe Funktionsweise), die Geräte-paare können sowohl in einem Raum, als auch raumübergreifend eingesetzt werden, innerhalb einer Nutzungseinheit ist auch eine stockwerkübergreifende Zuordnung möglich. Durch ausreichend dimen-sionierte Überströmöffnungen (z.b. Türluftgitter oder gekürztes Türblatt) muss eine Luftströmung zwischen den zu lüftenden Räumen ermöglicht werden. Damit durch eingeblasene Luft (Zuluftphase Lüftungsgerät) kein Geruchsübertrag in andere Räume erfolgt, sollten bei der Be-/ Entlüftung von Küchen, Bädern oder Toiletten mit Fenstern immer zwei im Gegentakt arbeitende Geräte installiert werden. In innenliegenden, fensterlosen Ablufträumen wie Küchen, Bädern und Toiletten dürfen die Fox up Geräte nicht eingesetzt werden da ein Anschluss der Geräte an einen Schacht oder eine Rohrleitung nicht zulässig ist. Hier empfiehlt sich der Einsatz eines Abluftventilators gemäß DIN T.3, z.b. der Ventilatortyp BRAVO. Die Geräteinstallation in Kellerräumen mit Lichtschächten ist ebenfalls nicht möglich, da eine Rezirkulation der Fortluft nicht ausgeschlossen werden kann. Um eine Rezirkulation bei Fassadenmontage der Geräte zu vermeiden, sollte zwischen einzelnen Geräten ein Mindestabstand von 1,2 m eingehalten werden. Wir empfehlen, bei einer windexponierten Lage des Gebäudes (mittlere Windgeschwindigkeit > 5 m/s) auf den Einsatz des Gerätes zu verzichten. Um Zugerscheinungen durch den Betrieb der Lüftungsgeräte zu vermeiden, sollten die Geräte nicht im direkten Aufenthaltsbereich von Personen (Sitzgelegenheiten, Betten) platziert werden, beachten Sie, daß der raumseitige Luftdurchlaß nicht durch Möbel oder Gardinen beeinträchtigt wird. 29
