REFRIGERANT SUPPLEMENT
In case that the length of the refrigerant pipe is over 5m, refrigerant must be supplemented.(max.20m)
But the amount of the supplementary refrigerant is variable according to installing condition, so check the condition be-
fore supplementing refrigerant.
This work must be carried out by qualified employees.
• In case that vertical length is over 10m, install an oil trap on the gas pipes.
