Checklist 2
Calculate the additional amount of refrigerant from the following:
Firstly enter the total length for each liquid pipe in the following table and then calculate the additional amount of
refrigerant by pipe length.
(Table 1) Additional amount of refrigerant by pipe length
Next, refer to the following table for the corrective amount of refrigerant depending on the indoor units (B).
(Table 2) Corrective amount of refrigerant depending on the indoor units
Next, refer to the following table for the corrective amount of refrigerant by outdoor HP (C).
(Table 3) Compensation by outdoor HP
Lastly, add the additional amount of refrigerant by pipe length (A), the corrective amount of refrigerant depending
on the indoor units (B) and the corrective amount of refrigerant by outdoor HP (C). This is the final additional
amount of refrigerant.
If a minus sign is indicated as the result, do not add the refrigerant (= 0 kg).
