● Empty and dry the entire refrigerant circuit using a vacuum pump connected to the low and high pressure
tap until the vacuometer reads about 10Pa. Wait a couple of minutes and check that this value does not
rise to more than 200Pa.
● Connect the refrigerant gas cylinder or a filling cylinder to the low pressure line pressure gauge
connection.
● Fill with the quantity of refrigerant gas indicated on the rating plate of the unit.
● Always check the superheating and sub-cooling values. In the nominal operating conditions for the
appliance, these should be between 5 and 10°C and between 4 and 8°C respectively.
● After a couple of hours of operation, check that the liquid indicator indicates circuit dry (dry-green)
Note:
1) In the event of partial leaks, the circuit must be completely emptied before being refilled
The R410A refrigerant must only be filled in the liquid state.
Operating conditions other than nominal conditions may produce considerably different values, Seal testing
or identification of leaks must only be carried out using R410A refrigerant gas, checking with a suitable leak
detector.
2) The use of a different refrigerant or oils may cause serious damage to the compressor.
Oxygen, acetylene or other inflammable or poisonous gas must never be used in the refrigerant circuit as
they may cause explosion or poisoning.
