FILLING AND VENTING
Filling the hot water heater
1. Open a hot water tap in the house.
2. Fill the hot water heater through the cold water
connection (XL3).
3. When the water that comes out of the hot water
tap is no longer mixed with air, the water heater is
full and the tap can be closed.
Filling and venting the charge coil
Filling
1.
Open the externally mounted filling valve. Fill the
coil in the hot water heater and the rest of the cli-
mate system with water.
2. Open the vent valve (QM22).
3.
When the water that exits the vent valve (QM22) is
not mixed with air, close the valve. After a while,
the pressure starts to rise.
4. Close the filling valve when the correct pressure is
obtained.
Venting
1. Vent the coil via the vent valve (QM22) and the rest
of the climate system via the relevant vent valves.
2.
Keep topping up and venting until all air has been
removed and the pressure is correct.
