Diffusers/valves
Inlet diffusers, extract valves and cooker hood (Fig. 7)
Mount inlet diffusers in all living rooms, dining areas and bedrooms. Extract louvers to be installed in
bathrooms, laundry room, WC and kitchen.
Note: Even if the cooker hood is connected to the unit, a separate extract louver must be installed
in the kitchen.
In the VR 250 ECH/B the extract air from the cooker is led directly to the extract fan, bypassing the heat
exchanger. In order to obtain heat recovery from the basic ventilation, the extract louver in the kitchen
must be connected to pos.6,
fig. 1 together with extract from the wet rooms.
Note: The cooker hood must be equipped with a damper leaving no opening in closed position
(without opening for basic ventilation). Bung, provided with the cooker hood must be
mounted.
Air stream from inlet diffuser mounted on the wall (where the ceiling is horizontal), must have throw length,
so that the air is supplied to the room alongside the ceiling. Air supply through extract louvers will ensure
an air stream with throw length, and extract louvers can therefore be used as inlet diffusers when mounted
in the wall close to the ceiling. Use frames to ease the removing of diffusers for cleaning.
