Step 3.4 Adding refrigerant

If you use a pipe longer than the length specified in the piping codes and standards, you must add 10g(09/12 )/15g(18/24)/40g(30) of refrigerant R-410A for each extra metre. If you use a pipe shorter than the length specified in the piping codes and standards, the evacuating time is normal. Refer to the Service Manual for further details.

CAUTION

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

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

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, take the following instructions:

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

	Siphon
Charge the refrigerant
		Charge the refrigerant turning
standing the cylinder upright.		the cylinder upside down.
<Cylinder with siphon>		<Cylinder without siphon>

NOTE

•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 siphon, upset it.
