EXHAUST AIR
Connecting the exhaust air
The heat pump uses the heat that is in the building's
ventilation air to heat the building and the hot water at
the same time that the house is ventilated.
The hot air is transferred from the rooms to the heat
pump via the exhaust air module.
NOTE
An air filter (HQ12) (enclosed), minimum classi-
fication G2, is required on the exhaust air duct
for this connection. The filter must be cleaned
regularly.
Caution
Noise from the fan can be transferred via the
ventilation ducts.
