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.

Next, refer to the following table for the corrective amount of refrigerant by outdoor HP (B).
(Table 2) Compensation by outdoor HP
Lastly, add the additional amount of refrigerant by pipe length (A) and the corrective amount of refrigerant by
outdoor HP (B). This is the final additional amount of refrigerant.
