WARNING
Only qualified professionals are permitted access to the
inside of the appliance.
If the pressure gauge is not accessible, contact the
installer.
4 Have the installation's water pressure checked.
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).
¼ See chapter: "Top up the installation with water",
page 20.
4 Carry out a visual check for the presence of any water leaks.
4 Open and close the radiator valves several times a year (this
prevents 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
