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 main-
tains the flow in the climate system during pool char-
ging.
Pipe connections
1. If the indoor module has already been installed
and filled with water, the climate system and in-
door module must be drained of water. See the
Installer manual for the indoor module for further
instructions.
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.
