Important information to the installer

This manual provides you with all the information necessary to install the heat
pump. The manual is divided into several sections. The order of these is based
on the recommended installation sequence. Use the supplied checklist during
installation.
Before installation remember:
Installation of the heat pump should be performed by a qualifi ed installer.
If the heat pump needs to be taken downstairs it may be temporarily tilted with the compressor downwards. However,
never lay the heat pump down or transport it horizontally.
Before the heat pump is commissioned, the heat transfer systems, the hot water cylinder and the heat pump must be
fi lled and vented.
Check that pipe connections on the cold and hot sides are intact and have not shaken loose during transport.
The HTF pump should be running when the heat transfer system is vented.
The control unit measures the phase sequence and gives an alarm if the power supply has been connected incorrectly.
Wiring should be kept as short as possible to protect the system from downtime, for example during a thunderstorm.
Heat pump installation, energy drilling and collector installation must be carried out in accordance with applicable
regulations.

Checklist

Each heat pump installation is unique. However, the following checklist will give you a general description of how the
installation should be carried out.
1. Place the heat pump on a fl at surface. Adjust the height using the rubber feet.
2. Check that the bore hole for the collector hose has been bored according to applicable regulations (responsibility of
the drilling company).
3. Fit the incoming and outgoing pipes for the heating and heat transfer fl uid circuits as well as the expansion tank.
4. Fit the particle fi lters and valves.

8. Fill and vent the heating and heat transfer systems before commissioning.
9. Connect the heat pump to the electrical system. Use the appropriate electrical diagram.
10. Connect the external switch as well as additional heat if used, and an earth-fault breaker.
11. Connect a general alarm, external controls and load monitor if used.
12. Commission the heat pump by making all the necessary settings on the control panel.
