To obtain the necessary air exchange in every room of
the house, the exhaust and supply air devices must be
correctly positioned and adjusted. The supply air flow
is adjusted to correspond to approximately 80 % of
the exhaust air flow. A defective ventilation installation
may lead to reduced heat pump efficiency and thus
poorer operating economy, and may result in damage
to the house.
NOTE!
A duct in a masonry chimney stack
must not be used for extract air.
To prevent fan noise being transferred to the exhaust
and supply air devices, it may be a good idea to install
a silencer in the duct.
As the heat pump contains a flammable refrigerant
(propane R290), the air ducting system must be
earthed. This is done by making a sound electrical
connection to the four ventilation ducts using the four
earthing cables supplied. The cables must then be
connected to the earthing studs on top of the top cov-
er.
Connections should be made via flexible hoses, which
must be installed so that they are easy to replace. The
extract air and outdoor air ducts are to be insulated
using diffusion-proof material along their entire lengths.
Provision must be made for inspection of the duct.
Make sure that there are no reductions of cross-sec-
tional area in the form of creases, tight bends etc,
since this will reduce the ventilation capacity. All joins
in the ducting must be sealed and pop-riveted to pre-
vent leakage.
The air duct system should, at a minimum, be of air
tightness class B and in general designed according
to applicable building standards.
