Additional refrigerant charging of MCU is 0.5kg (1.1lb) for every MCU kit
f
If AHU Kit is included among the indoor units, add 0.018kg(0.04lb) of refrigerant for every 1MBH of AHU capacity
increase.
3. The total amount of additional refrigerant charging = the amount of refrigerant charging for pipe + the amount of
refrigerant for each indoor unit.
Ex) The amount of additional refrigerant charging = 3600g + 700g = 4300g
