During operation, the heat pump tends to lower the room tem-
perature if the air ducting is not to the outside.
A suitable protection grille must be installed at the air extrac-
tion pipe to the outside to prevent any foreign bodies from
entering inside the equipment. To ensure maximum product
performance, the grille must be selected from those with low
pressure loss.
To avoid the formation of condensation water: insulate the air
extraction pipes and the ducted air cover connections with a
steam-tight thermal covering of adequate thickness.
Install silencers if deemed necessary to prevent noise due to
the flow. Equip the pipes, wall outlets and connections to the
heat pump with vibration-damping systems.
ATTENTION!: The simultaneous operation of an
open-chamber hearth (e.g. open fireplace) and
the heat pump causes a dangerous negative
pressure in the room. The negative pressure
can cause the return of exhaust gases into the
room.
Do not operate the heat pump together with an
open-chamber hearth.
Only use sealed-chamber hearths (approved)
with separate combustion air supply.
Keep tight and sealed the doors of boiler rooms
that do not have the inflow of combustion air in
common with living areas.
