Start-up
Central heating
Filling with water
Fill central heating circuit with water via the feed tap until the correct water pressure is obtained. It is important that all circuits in the
central heating system are open during filling.
There is an automatic vent fitted, which is activated wen filling with water. Check that the cover on the vent is loose.
Once the central heating circuit has been filled to the correct water pressure, the circulation and heat pump can be started.
Topping up water
The water pressure must be carefully checked the first few days, even several times a day. It may be necessary to top up the water in
the central heating circuit if the water pressure has dropped.
The water pressure will stabilise after a few days, after which the checks can be reduced to once a month.
Check the particle filter
There may be some particulate matter in the central heating circuit, and the heating pump must be checked immediately after being
put into operation.
The filter must be checked several times a day just after installation until it stays clean. With normal operation, it is enough to check
the filter twice a year.
Cleaning the particle filter:
1. Switch off the heating pump on the control panel (Settings: Central heating / Standby functions /Turn off central heating)
2. Turn the shut-off valve to close off the circulation
3. Remove the filter and rinse until clean
4. Replace the filter
5. Turn the shut-off valve to open up the circulation
6. Switch the heating pump back on
ATTENTION
Before starting the heat pump and the circulation pump, the central heating circuit must be filled with water.
ATTENTION
Ordinary water or all common types of antifreeze can be used.
ATTENTION
It is important that the circulation and heating pump is switched off while topping up the water.
ATTENTION
If the central heating circuit requires topping up after the start-up phase, it should be checked for leaks.
