If necessary, top up the water level in the heating system
(recommended hydraulic pressure between 1.5 and 2 bar).
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 See chapter: "Changing the operating mode", page 17.
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 in heating mode.
¼ See chapter: "Changing the operating mode", page 17.

7. When the pump has stopped, bleed again and top up the water
pressure.
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.
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.
