The unit can be installed in a warm, half warm or cold room. If the unit is installed in a cold
room, is it to be equipped with a 100 mm thick cover of isolation. The unit can be installed
i.e. in a storage room or on an attic.
The unit should be placed on a plain surface on a elastic material that muffle sound. For
instance a 100 mm thick isolation plate is suited as bedding. The unit can be mounted on
its edge, so that the front edge is higher than the back edge.
If the unit is used to ventilate a facility with a swimming pool it must be drained. There are
two (2) drain outlets of which the other should be taken it to use, depending of the position
of the unit. At the time of delivery, both outlets are plugged.
Phases of installation:
A. Place the unit on the isolation plate (i.e. a chipboard covered with 100 mm isolation) or
in a storage room or on the attic on a custom made shelf. Take into consideration the
possible drain.
B. Check that there is at least 60 cm of free space in front of the service hatch and that
the electrical inlets are accessible. Take into consideration that opening the lock bolts
require a certain amount of space.
C. Connect the ducts to the tubes on the unit. It is recommended that silencers be
installed to the exhaust air and supply air ducts. Silencers, see page 7.
F. If the unit’s condensation drain is to be used, connect a pipe between the drain outlet
and the nearest floor drain or water trap of a sink. Connecting the unit directly into the
sewage system is not allowed. If the unit is installed in a cold room the drain pipe must
be isolated so it doesn’t freeze.
N.B.! To reduce the weight of the unit remove the rotor before mounting on the wall.
