These are minimum requirements that only take service needs into account. National statutory requirements for electrical safety may deviate from this. Check which rules apply in your country.
2.3 Mounting requirements
The unit is intended for use in washing rooms, baths, attics or other suitable locations. The unit is available in left and right versions (exhaust air nipple to the left or right), depending on what is the most favourable duct location. In wet rooms the unit must be located in zone 3 (minimum
0.6 m from the edge of the bath and 1.2 m from the shower head).
2.4 Recommended sound isolation - Horizontal mounting
When mounted horizontally the unit should be on a firm base, for example gypsum or chipboard, which must be level. If the room below is sensitive to noise, the panel can be placed on a very firm panel of mineral wool for maximum sound absorption (Fig. 2). The unit should not be placed directly above a bedroom.
2.5 Recommended sound insulation - Wall mounting
For wall mounting, the (included) wall bracket fixed to the unit is used. The unit must not be placed on a wall with rooms on the other side which are sensitive to noise. The wall must be sound-insulated. If necessary, use double plasterboards on the wall. Interrupted studs must be used.

5 Mounting of S4 R/S7 R
These units are heavy and therfore it is necessary to use additional studs (transcoms) between the pillars on 48 x 98 mm, or 48 x 148 mm for suspension above and support bracket below (c/c distance 900 mm) If using existing wall framework, mount an 18 mm plywood wallboard first to distribute the weight, minimum the seize of the unit. The wallboard must be secured to the framework in at least 3 places with countersunk screws (6 attachment screws 4.5 x 50 are included).
Mounting alternatives for the unit:
• Wall mounting (Fig. 15)
• Horizontal mounting (17)
5.1 Wall Mounting
The enclosed wall brackets are used for wall mounting (Fig. 14A/14B). The wall must be sound insulated to prevent noise transfer. The unit should be placed against a wall which does not have a sound sencitive adjoining room.
Duct connection top (Fig. 16)
• Attach one of the 2 mounting brackets (Fig. 16A) to the ventilation unit with the enclosed screws (Fig. 16B).
• Lift the unit onto the wall and fasten with screws.
• Fix the unit at the bottom with the second enclosed mounting bracket (Fig. 16A).
5.2 Horizontal Mounting
The ventilation unit should be installed on a firm base (e.g. gypsum/chipboard) that is level. If the room is noise sensitive, place the panel on a very firm panel of mineral wool for additional sound reduction (Fig. 2/Kap. 2). The unit should not be installed above a bedroom.

6 Connections of ducts and electrical
connection
• The ducts usually come from joists and are connected to the nipples on the top of the unit.
• Ensure that the ducts are connected to the right nipple. See the labelling on the unit (top/bottom and behind door). The symbols are explained on page 3 and the placing is shown on measurement drawing in Chap. 1.
• Pull the duct insulation well up to the unit.
• To avoid condensation, it is very important for the outdoor air duct to have insulation and a plastic sleeve pulled right down to the unit. Seal the plas­tic sleeve to the unit with tape.
The outdoor air duct is normally designed with 25
mm insulation.
• Lay the outdoor air duct with a slight incline to­wards the outdoor air cap so that any water that enters drains out again.
• With a short distance between the unit and the exhaust point, sound insulation must be installed to meet the requirements for the outdoor sound level.
• Ducts must have good sound insulation, particu­larly above the unit.
• All electrical connections must be made by quali­fied personell only.
The unit must be equipped with a separate earth-leakage circuit-breaker.
Power Cord
The unit is supplied with a 1.8 m cable and plug (which also functions as the service switch). The cable emerg­es on the top of the unit (front) on the left side of a right model and the right side of a left model. This is con­nected to a 230 V 50 Hz single-phase earthed power point that is located in an easily accessible position close by. For fuse types, see chapt. 14.
6.1 Automatics
The control package is supplied with the unit. The low­voltage cable must be laid between the unit and the switch unit. See separate automatics documentation.
The low-voltage cable must be laid at least 30 cm away from the 230 V cable. For flush in­stallation, lay the cable in 20 mm conduit pipe.
6.2 Supply Air Temperature Sencor (B1)
Temperature sensor B1 must be placed after the water battery.
This should be placed in the supply air duct (red on Flexit Drawing/
Symbold Used
page 3) approx. 1 m from the unit. Roll out the marked wire coil on the unit located close to the supply air intake. Drill a Ø 7 mm hole in the duct where the sencor can be placed. Seal the hole with a sealant and tape the wire on the outside of the duct to keep in place.
6.3 Temperature sensor for water battery (B5)
In order to avoid that the water battery is destroyed by frost a temperature sensor (B5) must be installed on the return water pipe where the cold water leaves the battery.

S4 R/SL4 R 14466
S7 R 14467
7.5 Connections
Use the recommended connection (see Fig. 20) unless specified otherwise. The water supply must be at the bottom of the water battery - the return must be on the top. Place the adjustment valve as close to the unit as possible. (Please note that many valve motors can go in both directions and this can be set on the motor. Set it so that the valve opens on an increasing 0-10 V signal.)
Before connecting the water battery, it is necessary to check that the inspection doors are accessible and there is space enough to change the water battery.
If you use a water battery that has not had glycol (or another antifreeze) added, the unit should be in a heated room on account of the risk of frost in the battery. Install air dampers with spring-loaded return for outdoor air. Place the unit close to a gully to avoid damage caused by any water leaks.

10 Installation of External Kitchen
Hood
10.1 Technical Data
Width: 60 cm El. connection: 230 V earthed Light: Fluorescent tube, base G23, 11 W
10.2 Installation of External Kitchen Hood
Installing the sleeve and damper
The sleeve is inside the volume hood on delivery. Place the damper shaft A in the hoop under the damper lid, see Fig. 21. Ensure that the grips B are under the edge of the plate. The sleeve snaps into place.
Installing the kitchen hood
The kitchen hood must be placed under or recessed in the row of cabinets, see Fig. 22. The distance between the cooker and the kitchen hood must be at least 40 cm. For a gas cooker, the distance must be 65 cm. The kitchen hood can also be installed using wall mountings that can be purchased as accessories, Fig. 13. Instructions for installing the accessories are enclosed with them.
Electrical installation
The kitchen hood is supplied with a cable and earthed plug for connection to an earthed socket. The control cable (12 V) is connected between marked 2-core cables from the kitchen hood and the unit. The colour of the cables connected to the terminals is of no significance. The control cable between the kitchen hood and the unit must at least be of type 2 x 0.75 mm2. The voltage between the units is 12 V DC.
The installation must be carried out by an authorised expert.
Adjustment
For adjustment of the kitchen hood, see Chap. 12, and for the unit see Chap. 13 Adjustment Curves.
Fig. 21
Fig. 23
Fig. 22

11 Adjusting the Kitchen Hood
11.1 Basic Ventilation
The basic ventilation is adjusted by setting the sliding damper A to the desired position as shown in detail B in Fig. 24 (see diagram 13.1).
11.2 Forced Ventilation
Open the damper and remove the throttle piece C, Fig. 25. Adjust the forced ventilation by cutting out a suitable number of rings in the throttle piece, Fig. 26 (see diagram 13.2). Ensure that the guide slot D is in position when the piece is in place.
11.3 Pressure Drop Measurement
The pressure drop is measured by the hose being fitted to the measuring outlet at the front of the damper, Fig. 27. The pressure drop corresponds to the axis in the adjustment diagram (left side), see Chap. 13.
If basic ventilation is not required, the enclosed piece can be installed, see Fig. 28 for the procedure.

15 Important Safety Instructions
To reduce the risk of fire, electric shock or injury, read all the safety instructions and warning texts before using the unit.
• This unit is only designed for ventilation air in buildings.
• It must not be used to extract combustible or flammable gases.
• Remove the power plug before commencing any service and maintenance work.
• Before you open the door, the unit must be dead and the fans must have been given time to stop (min. 3 minutes).
• The unit contains heating elements that must not be touched when they are hot.
• The unit must not be operated without the filters being in place.
• Do not cook any combustible substances or flame anything under the fan (only when a kitchen hood is connected).
• Do not leave a saucepan or frying pan containing oil or grease unsupervised (only when a kitchen hood is connected).
• Follow the instructions in the user manual.
To maintain a good indoor climate, comply with regulations and, to avoid conden­sation damage, the unit must never be stopped apart from during service/mainte­nance or in connection with an accident.
16 Functional Description
In the (HR-R) rotor, the cold outdoor air and the warm extract air pass each other without being mixed. With this principle, a large part of the heat in the extract air will be transferred to the supply air (see drawings in Chap. 8). If the outdoor temperature is extremely low, a thermostat-controlled (EB1) heating element will also ensure that the supply air has the desired temperature. This supply air is passed via ducts and valves to living rooms and bedrooms. The extract air is extracted either from the same room or via door gaps/ overflow gratings to toilets and wet rooms. The used air is passed via a duct system back to the unit, emits heat and is blown out of the building via a roof hat or wall grating. The temperature of the supply air is controlled by the rotor. Only when the rotor is not able to maintain the set temperature, will the heating element start up. When there is no need for heating (for example in the summer), the rotor will stop.
16.1 Heating Elements
The heating elements are protected against overheating by the (F20) overheating thermostat, which switches off at 60 °C. As an additional safety measure, the (F10) overheating thermostat switches off at 85 °C. The F10 overheating thermostat can be reset manually by pressing the reset button. You will find the thermostat by opening the unit doors (located right above the heating element).
16.2 Operation via Kitchen Hood (SL4 R)
A - Knob for damper/timer B - Pushbutton for light Open the damper when preparing food. The damper closes automatically after a maximum of 60 minutes or if you turn the damper knob to
as shown in Fig.
29. When the timer is activated, the air handling unit is forced in addition to the damper function.
This is purely a ventilation system and not a heating system. The home must be heated in the normal manner. The heat gained from heat recovery must be seen in relation to a situation in which the extract air is blown right out of the home without recovery.

17 Cleaning - Maintenance, S3 R
Before opening the door of the heat recovery system or carrying out maintenance on the kitchen hood: switch off the heat, let the fans continue for three minutes to remove hot air, remove the power from the unit and wait 2 minutes before opening the doors.
Fans: Item nos. 6 and 7/Chap. 9 General Drawing. The fans must be cleaned once pr. year. The fans are
cleaned with a small brush and compressed air, if available. NB! Do not use water. Dismantle the fan as follows: Open the doors as instructed. Pull out the electric quick-release contact for the motor. Unscrew 2 screws at the front of the motor’s mounting plate. The fan can then be pulled carefully down and out of the unit.
Filters: To preserve a healthy indoor environment, it is important to change filters when they are dirty.
Dirty filters lead to:
Increased air resistance in the filter – less air in the home – the risk of bacterial growth in
the filter – in the worst case scenario, the system can be damaged.
How often the filters need to be changed depends on the degree of contamination of the air where
they are installed. In general, the filters need to be changed once a year, preferably in the autumn (after the pollen season). In areas with a lot of dust and contamination, the filters should be changed in the spring and autumn. The supply air filter and extract air filter (2 and 1) consist of a compact filter (F7). These are pushed into place.
It is recommended that you order a filter subscription to ensure full benefit from the system and the
cheapest prices.
Order no. for a complete set of filters: 12328 When changing filter, please perform an overall check of the ventilation unit.
Rotor: As the system has filters installed with a high tightness class, it is not normally necessary to clean
the rotor. If, for various reasons, it should still be necessary, dust can be removed with a soft brush. Further cleaning is possible if you remove the rotor, spray it with fat-soluble detergent and then blow it clean from the opposite side. Distance approximately 60mm and max. pressure 80 bar. Ensure that the motor is not exposed to water during cleaning. Ensure that all seals around the rotor are intact and tight.
Do not use detergent that is harmful to aluminium or the environment.
Valves and duct system: Clean the valves at least once a year. The duct system must be cleaned at least every 10 years.
Outdoor air intake: Check once a year that the grille is not clogged.
Roof hat: Check once a year that the drainage gap at the bottom is not clogged with leaves. This applies
only if the system has a roof hat.

Before opening the door of the heat recovery system or carrying out maintenance on the kitchen hood: Switch off the heat, let the fans continue for three minutes to remove hot air, remove the power from the unit and wait 2 minutes before opening the doors.
Fans: Item pos. 5 and 6/Chap. 9 General Drawing, SL4 R. The fans must be cleaned once pr. year. The
fans are cleaned with a small brush and compressed air, if available. Remove the fans as follows: (Fan item no. 6) Remove the cover in front of the fan by pressing the snap locks at the bottom of the cover. For both fans: pull the fan out of the track and disconnect the contact. The motor and fan blades are removed by unscrewing the 4 screws in the round motor plate and carefully pulling the motor out of the motor housing. Mounting takes place in the reverse order.
Filters: To preserve a healthy indoor environment, it is important to change filters when they are
clogged/dirty. Clogged filters lead to:
Increased air resistance in the filter – less air in the home – the risk of bacterial growth in the filter – in the worst case scenario, the system can be damaged.
How often the filters need to be changed depends on the degree of contamination of the air where they are installed. In general, the filters need to be changed once a year, preferably in the autumn (after the pollen season). In areas with a lot of dust and contamination, the filters should be changed in the spring and autumn.
The supply air filter, which cleans the outdoor air (item no. 2) is a compact filter (filter class F7).
The filter is pushed in place in the fixing rails. The extract air filter (item no. 1) is a compact filter (filter class F7) and is located in its own drawer which can be pulled right out after the finger screws have been removed. We recommended that you order a filter subscription for full benefit from the system and the cheapest prices.
