4.1 Placement into service of the water circuit
Fill the container via the connecting branch, and aerate the tank by letting
one of the hot water taps located at the highest elevation within the dwelling
stand open until air no longer comes out with the water.
The container can normally hold 285 litres of water.
Check the entire circuit to be sure it is sealed.
4.2 Electricity – connecting
Connect the heat pump to the public electrical grid.
4.3 Cooling circuit
The cooling circuit is delivered ready to run and no work need be performed
on it. The electronic controls automatically take over all functions
concerning the operation of the compressor as well as the ventilator.
If needed, set the controls to the desired water temperature. The factory
setting is 50° C (see the operating instructions for more detailed
directions).
4.4 Hints for energy savings
Do not set the water temperature higher than necessary.
The best utilisation of the heat pump occurs at low water temperatures.
The use of circulation will increase the energy consumption of the heat
pump significantly.
