9-9. Additional refrigerant charge
Charge refrigerant in a liquid state.
-Charging refrigerant in the gaseous state will change the composition of the refrigerant and lead
to a performance drop.
Do not use a charging cylinder when charging refrigerant.
-The use of a charging cylinder may change the composition of the refrigerant and lead to a
performance drop.
The amount of refrigerant that is shown in the table below is factory-charged in the outdoor units. The amount
necessary for extended piping is not included and needs to be added on site.

Both refrigerant overcharge and undercharge will cause problems. Charge the system with the proper amount of
refrigerant.
Record the added refrigerant amount on the label attached to the control box panel for future servicing.
9-9-1. Calculation of the amount of additional refrigerant
・
The amount of refrigerant to be added depends on the size and the total length of the liquid piping.
・
Calculate the amount of refrigerant to be charged according to the formula below.
・
Round up the calculation result to the nearest 0.1 kg (0.1 oz).
