In order to insure your appliance operates correctly for
many years, the maintenance operations described
below are required at the start of each heating season
Generally, these are performed as part of a service
contract
4 1 Heating circuit checks
Periodically check the water pressure in the Heating
circuit :
-
Radiator Circuit :
pressure between 1 5 & 2 bar
-
Heating Floor Circuit :
the pressure in the floor system
when it is cold and when HP is stopped must be 1 5 bars
If filling and re-pressurization are required, check what
type of fluid has been used initially (In any doubt,
contact your installer)
If frequent refills are required it is essential that you look
for any leaks
"
The frequent water supply is at risk of scaling for
the Heat exchanger and degrades performance
and longevity of it
-
Check and clean the filter of the filter valve on the return
Heating circuit
-Vent the dirt separator (optional)
4 2 Brine circuit checks
-Check glycol (Ph + Refracto) once a year
Use monopropylene glycol only The recommended
concentration is 30% minimum
Never use
monoethylene glycol
Contact your installer
-
Brine Circuit :
Check that the pressure Brine circuit is
higher than 1 bar
-
Check and clean the filter of the filter valve on the return
Brine circuit
4 3 Refrigerant circuit checks
-Make check the refrigerant cycle by your installer
