Adding Refrigerant
Add refrigerant charge according to table below:
If you use a pipe... | Then... | |
|
| |
longer than 5 meters, | 'A'g of refrigerant R410A must | |
be added for each extra metre. | ||
| ||
shorter than 5 meters, | The purge time is normal. |
Refer to the Service Manual for further details.

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
R410A 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.
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 | Charge the refrigerant turning | |
| the cylinder upright. | the cylinder upside down. |
Note | If R410A 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 an electronic balance. If cylinder doesn’t have syphon, upset it.
