Installation

3Open the valve of the low pressure side of manifold gauge anticlockwise.

4Evacuate the air in the connected pipes using the vacuum pump for about 15 minutes.

Make sure that pressure gauge shows -0.1 MPa (-76 cmHg, 5 torr) after about 10 minutes. This procedure is very important to avoid a gas leak.

Close the valve of the low pressure side of manifold gauge clockwise.

Turn off the vacuum pump.

Check for 2 minutes if there is any pressure change.

Remove the hose of the low pressure side of manifold gauge.

5Set a valve cork of liquid and gas service port to the open position.

Step 3.4 Adding refrigerant

If you use a pipe longer than the length specified in the piping codes and standards, you must add 20 g (for ✴✴18/24✴✴) 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.
