Calculate the additional amount of refrigerant from the following:
Additional refrigerant
=
charge amount at local
site
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 depending on the indoor units (B).

Next, refer to the following table for the corrective amount of refrigerant by outdoor HP (C).

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).
