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 high-pressure piping and 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).
(1) Units "m" and "kg" (In an R2 system)
<Formula>
・When the piping length from the outdoor unit to the farthest indoor unit is 30.5 m (100 ft) or shorter
