Pipe connections
General
When the indoor module is docked to a pool, the charge
circuit must be supplied with an external charge pump
(GP12) as it is not possible to use the internal charge
pump. The internal circulation pump in maintains the
flow in the climate system during pool charging.
Pipe connections
1. If the indoor module has already been installed and
filled with water, the climate system and indoor
module must be drained of water. See the Installer
manual for the indoor module for further instruc-
tions.
2. Pipes to and from the pool are connected between
the heat pump and the indoor module.
TIP
To prevent unnecessary heat losses insulate the
pipes.
Circulation pump
Install the ball valves on the circulation pump. Use the
flat gaskets supplied to seal.

pool and port B towards the heating system. Install it so
that port AB is open towards port B when the motor is
in standby mode. In the event of a signal port AB opens
towards port A.
