4.1. Water connections
Dirt in the pipe work must be avoided. After installation of the external pipes flush if
required before connection of the domestic hot water heat pump.
If no circulation of water is needed, make sure that the circulation connection is
properly sealed.
When installing the pipes please ensure that the pipe connections are not excessively
stressed. Use a pipe wrench to relax torque forces on the pipe connections.
The water pipe outlet should be insulated to reduce heat losses to the ambient and to
reduce the risk of injuries and burns.
4.2. Location of connecting pipes
Hot water outlet pipe is mounted on the upper connecting branch.
If the unit is filled with the hot water circulation access, the middle connecting branch
is used for hot water return. Inlet of fresh cold water is mounted on the bottom con-
necting branch.
4.3. Connection of condensate drain
While the heat pump is running, conden-
sate will form, which is to be discharged
to the sewage drain via the condensate
drain pipe, Ø 19 mm connection outside.
The quantity of condensate depends on
the humidity, the air flow, and the temper-
ature of the air.
The condensate connecting branch must
be equipped with an air tight water trap
and run to a drain. The water trap must
contain a standing water column of at
least 60 mm.
Neglecting to install a drain trap can lead to damage to the appliance. If the drain trap
is not installed correctly, the product warranty is not valid.
