Connecting the ventilation
Connected to at least air tightness class B ducting
system (according to current norm). Must not be
connected to air conditioning systems containing a
large amount of dust or grease, or from rooms with
inflammable substances or gases that might reach
the heat pump.
Connecting spigots
Dimension Ø 125 mm, fitted with a rubber seal
must be used. The connection between the unit
and the ducting system should be made using
short, flexible hoses. Ensure that the hoses are
positioned so that they are easy to change.
Ducting insulation
Current norms shall be applied. Outgoing ducting
from the unit (exhaust air) must be insulated
against condensation without a break from unit to
brackets to roof hood. Refer also to the ventilation
drawing.
Fireplace, tumble dryer and kitchen fan
If a stove, e.g. a hot-air stove, is installed you
should avoid suction pressure (smoke in the
house). Make sure that the combustion air is
supplied directly to the stove via a separate duct,
alternatively via an extra air inlet through an
outside wall. The stove should always have tight-
closing doors.
Drying cabinets are connected directly to the
ventilation system. Condensation tumble dryers do
not affect the ventilation system. For evacuation
tumble dryers contact the ventilation contractor.
Cooker hoods should have a separate flue.
Adjusting the air flow
Must be carried out by the ventilation technician.
For adjusting the air flow, see the ventilation
drawing.
