4.1 Demands to the hot water circuit
In the hot water system the following materials may be used:
- Copper
- Stainless steel
- Brass
- Plastics
Depending on the used materials in the water circuit (in the house) wrong combi-
nations of materials may lead to corrosion damages. Special attention is required
when using galvanized steel or aluminium materials.
4.2 Starting to use the water circuit
- Fill the tank using the valve on the supply line, and let the air out through
one of the upper hot tap water valves until air no longer is present in the
tapped water.
- Check the entire water circuit for tightness.
- Connect the heat pump to the power supply.
After starting to use the system the entire water circuit must be checked for
tightness.
4.3 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.
4.4 Electricity – connecting
Connect the heat pump to the public electrical grid.
4.5 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).
