5 Assembly and Installation
5.1 General information:
The MVHR should be aligned horizontally using
a spirit level (for reliable condensate drainage).
The mains voltage must be 220-240V / 50-60
Hz.
If mounting on low density walls i.e. plaster
boarded stud walls use the following fixing
method:
 Use 15 mm nominal plywood backing board
to connect directly to the wall internal frame
stud and then mount the MVHR unit on the
plywood.
 Ensure internal thermal or sound insulation
is installed inside the stud wall to prevent
reverberation.
The MVHR must be installed in a frost-free room
preferably within the thermal envelope in order
to keep heat losses via the MVHR surfaces and
ventilation ducting to a minimum. Cellars, store
rooms and insulated attics are suitable for this
purpose.
The MVHR may only be installed in dry, non-
explosion-proof rooms (protection category IP
20). The ambient temperature must not exceed
+50°C.
This MVHR must not be fitted in rooms or areas
of the house with strong odours, which could
then permeate into the MVHR and contaminate
the fresh air supplied from the MVHR.
The following criteria must also be met:

Access is required for maintenance
work (e.g. changing the filter)
 The condensate drain must be con-
nected to a closed water trap and must
have a sufficient gap. Approx. 50cm is
ideal.
 If the condensate drain is located in a
frost-prone area, then heat tracing must
be provided.
5.2 Impact noise reduction:
With installation on wooden floors or other vibra-
tion-prone components, there may be combined
impact noise (use foam rubber mounts).
5.3 Connecting the ducting:
To prevent the transmission of vibrations, the
ducting should be connected flexibly to the
MVHR (e.g. using flexible ducting or fabric duct
fittings).
All ducting located in loft spaces and roof voids
etc., which are unheated, must be insulated, to-
gether with the duct runs from the unit to atmos-
phere.
All ducting fitted to the spigots on the MVHR
should be secured in place with jubilee clips or a
suitably sized plastic cable tie.
