Add refrigerant charge according to table below:

If you use a pipe longer than 5 m,

‘A’g of refrigerant R-410A must be added for each extra meter.

•The remaining air in the Refrigeration cycle, which contains moisture, may cause malfunction on the compressor.

•Always contact the service center or a professional installation agency for product installation.

Charging the refrigerant under conditions of liquid by using a liquid pipe

R-410A is a mixed type of refrigerant. It is necessary for recharging under conditions of liquid. When recharging refrigerant from the refrigerant cylinder to the equipment, follow the instructions below.

1.Before recharging, check whether the cylinder has a siphon or not. There are two ways to recharge the refrigerant.

Cylinder with siphon

Cylinder without siphon

Siphon

Charge the refrigerant standing the cylinder upright.

Charge the refrigerant turning the cylinder upside down.

• If R-410A refrigerant is charged with gas, the composition of the charged refrigerant changes and the

characteristics of the equipment vary.

•During the measuring operation of refrigerant quantity added use electronic scales.

If cylinder doesn’t have syphon, upset it.
