In order to ensure that your appliance operates correctly
for many years, the maintenance operations described
below are required at the start of each heating season
They are generally carried out as part of a maintenance
contract
4 .1 Regular checks
-Check the water pressure in the heating circuit
regularly (refer to the installer's recommended
pressure - between 1 and 2 bar)
-
If a filling operation and a pressure increase are
required, check what type of fluid was used initially
(when in doubt, contact your installer)
-
If frequent refills are required it is absolutely essential
that you check for any leaks
"
The frequent addition of water risks scaling
the exchanger and affects its performance and
lifespan .
4 .2 Checking the outdoor unit
Remove any dust from the exchanger, if necessary,
while making sure not to damage the blades
Check that there is nothing blocking the air flow.
• Checking the refrigeration circuit
If the amount of refrigerant in the system exceeds 2kg
(models > 10 kW), the refrigeration circuit must be
checked annually by an approved engineer (they must
have a certificate of competence for the handling of
refrigerants) Consult your heating engineer
4 .3 Hot water tank*
Maintenance on the tank must be carried out annually
(frequency may vary according to water hardness)
Consult your heating engineer
