Test operation

Note! Read the safety instructions!

Caution! The installation may only be commissioned if the heating system, water heater and brine system

have been filled and bled. Otherwise the circulation pumps can be damaged.

Caution! Any alarms that may occur in connection with the installation must be fault-traced.

Caution! If the installation is only to provide heat by an auxiliary heater during the installation, ensure that

the heating system is filled and bled and the compressor cannot be started. This is carried out by setting the

operating mode to AUX. HEATER.

8.1

Installation checklist

Before manual test operation, the following points must be checked to ensure that they have been correctly carried

out:

•
