f If AHU Kit is included among the indoor units, add 0 . 0 18kg(0 . 0 4lb) of refrigerant for every 1MBH of AHU capacity f
increase .
f Method to calculate total amount of additional refrigerant
f
- 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 . 7 kg (19 . 1 lb), therefore total amount of additional refrigerant
(ⓐ+ⓑ) should not exceed 91 . 3 kg (200 . 9 lb) .
