1. Connect the heat pump and heat pump module to the power.
2. Ensure that the circulation pump PC1 is running.
3. Remove the PC0 PWM plug from the circulation pump PC0 so that it
operates at maximum speed.
4. Activate the booster heater only.
5. Only deactivate the booster heater when the pressure has not
dropped in 10 minutes.
6. Connect the PC0 PWM plug to the circulation pump.
7. Clean the particle filter SC1.
8. Check the pressure on the pressure gauge GC1 and add more with
the fill valve VW2 if the pressure is below 2 bar.
9. Check that the heat pump is running and that there are no alarms.
10.Also vent via the other air vent valves of the heating system (e.g.
radiators).

Fill preferably to a higher pressure than the final one so
that there is a magin when the temperature of the
heating system rises and the air that has been dissolved
in the water is vented out via VL1.
