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).
