Configuration of connection pipe
4. The calculation method of additional refrigerant oil and refrigerant charging amount
after prolonging connection pipe
After the length of connection pipe is prolonged for 10m at the basis of standard
length, you should add 5ml of refrigerant oil for each additional 5m of connection
pipe.
The calculation method of additional refrigerant charging amount :
(1)When the length of connection pipe is above 5m,
Additional refrigerant charging amount= (the length of connection pipe - 5m) × 16g/m
(2)When the length of connection pipe is less than or equal to 5m,
There is no need to add the additional refrigerant charge,
i.e. the ②( in the above Figure 1 ) is zero.
Note：the ① is as the Refri.Charge shown in the outdoor nameplate.
the compressor for the appliance is fully charged before leaving the factory
