Clean the outside of the heat pump using a damp cloth and a mild
detergent.
CAUTION
Only a qualified professional is permitted to clean the
inside of the heat pump.
5.3 Top up the installation with water
The water pressure in the installation must be between 1,5 and 2
bar. Add water to the installation if necessary:
1. Open the valves on all radiators connected to the heating system.
2. Set the room thermostat to as low a temperature as possible.
3. Put the heat pump in shutdown/frost protection mode.
¼ "Changing the operating mode", page 18
4. Open the filling valve .
5. Close the filling valve when the pressure gauge shows a pressure
of 1,5 bar.
6. Put the heat pump into HEATING mode.
¼ "Changing the operating mode", page 18
7. When the pump has stopped, bleed again and top up the water
pressure.
8. Filling and bleeding the installation 2 times a year should be
sufficient to obtain an adequate hydraulic pressure. If it is often
necessary to top up the installation with water, contact your fitter.
5.4 Bleeding the heating system
It is essential that you bleed any air in the calorifier, the conduits or
the taps to prevent the annoying noises likely to be produced during
heating or when tapping water.
