4.Open the valve of the low pressure side of manifold gauge counterclockwise.

5.Purge the air in the connected pipes using the vacuum pump for about 15 minutes.

Make sure that pressure gauge shows -0.1MPa(-76cmHg) 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.

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

Adding Refrigerant

Add refrigerant charge according to table below:

If you use a pipe longer than 5m,

‘15’g of refrigerant R410A must be added for each extra meter.

If you use a pipe shorter than 5m,

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.
