Additional refrigerant charging of MCU is 0.5kg (1.1lb) for every MCU kit
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
