Warnings
Works to be performed by the refrigeration engineer
Once a year:
•
Cooling mode check (cycle inversion) (see "Installer" menu). Start cooling mode in
test mode and presence of cooling in the refrigerant lines OR air outlet T° - air inlet
T° ≥ 3° C.
•
Check fan operation: no abnormal noise or friction.
•
Check the heat exchange value. Based on the air temperature difference (air inlet
T°- air outlet T° ≥ 3° C). If value is not OK, check the following:
-
Check there are no traces of oil at the coolant connections.
-
Check with the electric leak detector (sensitivity of up to 5 g / year).
-
Check the refrigerant fluid charge.
If a leak check or charge inspection is required:
•
Leak check performed using an electronic leak detector (sensitivity of up to 5 g/year)
•
Charge recovery (amount recovered)
•
R32 charge top-up (amount added or topped up following recovery).
