If AHU Kit is included among the indoor units, add 0 .018kg(0 .04lb) of refrigerant for every 1MBH of AHU capacity
increase .

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 (220lb) . If the
refrigerant exceeds 100kg (220lb), separate the module so that weight of the refrigerant doesn't exceed 100kg (220lb) .
Ex .) For AM180
✴✴✴
, basic amount of refrigerant is 8 .7kg (19 .1lb), therefore total amount of additional refrigerant
(
ⓐ
+
ⓑ
) should not exceed 91 .3kg (200 .9lb) .
