Suggested additional oil charge: over 20 metres of linear development of the pipes, add a quantity of oil equal
to 2% in weight of the total refrigerant present in the circuit. Refer to the type of oil indicated on the compres
-
sor’s label.
For two-circuit units featuring at least one inverter-controlled BLDC compressor pay attention to the type of oil loaded into
each cooling circuit.
-
Circuits fitted with a BLDC compressor (in single or twin configuration with ON/OFF compressor) use IDEMITSU FV50S
oil.
-
the circuit featuring ON/OFF compressors only uses EMKARARE RL 32 H oil.
If needed, do not forget to top up the level with the correct type of oil without mixing the two different oils, as
they are not compatible. Always use the oil recommended by the Manufacturer of the compressor or a perfect-
ly equivalent oil. The use of an incorrect type of oil may cause serious damage to the compressors and imme
-
diately void any guarantee.
