Condensation
The condensate drain pan collects and leads away the con-
densation water.
NOTE
It is important to the heat pump function that
condensation water is led away and that the drain
for the condensation water run off is not posi-
tioned so that it can cause damage to the house.
Condensation run-off should be checked regularly,
especially during the autumn. Clean if necessary.
• 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.
TIP
Pipe with heating cable for draining the condens-
ation water trough is not included.
To ensure the function, the accessory KVR 11
should be used.
• Route the pipe downward from S2125.
• The outlet of the condensation water pipe must be at frost
free depth.
• 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.
