Refrigerant pipe installation
X f
Method to calculate total amount of additional refrigerant
- 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)
❇
Refer to the table
- 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 .
