Maintenance operations are important for the following reasons:
To guarantee optimum performance.
To extend the life of the equipment.
To provide an installation which offers the customer optimum comfort
over time.
Caution
An annual service of the heat pump is mandatory.
1. Check the hydraulic pressure in the installation.
Note
If the water pressure is lower than 1 bar, more water should be
added. If necessary, top up the water level in the heating system
(recommended hydraulic pressure between 1.5 and 2.0 bar, or
between 0.15 and 0.2 MPa)..
See
Top up the installation with water, page 22.
2. Carry out a visual check for any water leaks.
3. Open and close the radiator valves several times a year.
This helps to prevent the valves from seizing up.
4. Clean the outside of the heat pump using a damp cloth and a mild
detergent.
Caution
Only qualified professionals are permitted to clean the inside of
the heat pump.
AD-0000181-A
If necessary, top up the water level in the heating system (recommended
hydraulic pressure between 1.5 and 2 bar (0.15 and 0.2 MPa)).
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 shut-down/frost protection mode.
See
User settings, page 17.
4. Open the fill valve.
5. Close the fill valve when the pressure gauge shows a pressure of
1.5 bar (0.15 MPa).
6. Put the heat pump in heating mode.
See
AD-0000181-A
User settings, page 17.
7. When the pump has stopped, vent again and top up the water
pressure.
