Refrigerant pipe installation
f Method to calculate total amount of additional refrigerant X
- Amount of additional refrigerant depending on the pipe length (ⓐ)
- Amount of additional refrigerant for each indoor unit (ⓑ) = ∑(Amount of additional refrigerant for each
connected indoor unit)
- Total amount of additional refrigerant = ⓐ+ⓑ
❇ Sum of total amount of additional refrigerant and the basic amount of refrigerant should not exceed 100kg . If the
❇
refrigerant exceeds 100kg, separate the module so that weight of the refrigerant doesn't exceed 100kg .
Ex .) For AM200FXVAG✴, basic amount of refrigerant is 8 .4kg, therefore total amount of additional refrigerant
(ⓐ+ⓑ) should not exceed 91 .6 kg .
