Inspection of the installation
Current regulations require the heating installation to be
inspected before it is commissioned. The inspection must
be carried out by a suitably qualified person and must be
documented. The above applies to closed heating systems.
If the heat pump is replaced, the installation must be inspec-
ted again.
Condensation water trough
The condensate drain pan collects and leads away the con-
densation water.
It is important for the heat pump’s function that the con-
densation water is led away and that the outlet for the
condensation water pipe is positioned so as to prevent
damage to the building. Condensation run-off should be
checked regularly, especially during the autumn. Clean if
necessary.
Pipe with heating cable for draining the condensate drip
tray is not included. To ensure the function, the accessory
KVR 11 should be used.
• The condensation water (up to 50 litres/24 hrs) that col-
lects in the trough should be routed away by a pipe to an
appropriate drain, it is recommended that the shortest
outdoor stretch possible is used.
• The section of the pipe that can be affected by frost must
be heated by the heating cable to prevent freezing.
Pipe with heating cable for draining the condensation
water trough is not included.
To ensure the function, the accessory KVR 11 should be
used.
• Route the pipe downward from the heat pump.
• The outlet of the condensation water pipe must be at a
depth that is frost free or alternatively indoors (with reser-
vation for local ordinances and regulations).
• Use a water trap for installations where air circulation may
occur in the condensation water pipe.
• The insulation must seal against the bottom of the con-
densation water trough.
DRAINAGE OF CONDENSATION
Stone caisson
If the house has a cellar the stone caisson must be posi-
tioned so that condensation water does not affect the house.
Otherwise the stone caisson can be positioned directly under
the heat pump.
Drain indoors
The condensation water is lead to an indoor drain (subject
to local rules and regulations).
When routing pipes indoors, condensation water pipes must
be insulated against condensation.
Route the pipe downward from the heat pump.
The condensation water pipe must have a water seal to
prevent air circulation in the pipe.
