This manual gives you all the information necessary to install the heat
pump. The guide is divided into several parts in the order in which installa-
tion and commissioning must be carried out.
Before starting the installation:
The heat pump may be temporarily tilted with the compressor
downwards. It must never be laid down or transported horizontally.
Check that plumbing connections in the heat pump are intact and have
not shaken loose during transport.
If the heat pump is used in a system with fan-assisted radiators, the
water volume in the system is very small. During defrosting, the heat
pump draws some of the energy from the heating system, cooling
it down. It is therefore important that the fans in the fan-assisted
radiators run during defrosting, alternatively are connected to a tank of
approximately 100 litres.
Wiring should be kept as short as possible to protect the system from
downtime, for example during a thunderstorm.
Before the commissioning the heating system must be filled up and
completely vented.
