S4/S7 R 1000 mm 60 mm
A: In front/over the unit B: Distance to wall
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.
