Evacuating the connected pipes

1.Connect each assembly pipe to the appropriate valve on the outdoor unit and tighten the flare nut.

2. Tighten the flare nut first with your hands, and then with a torque wrench, applying the following torque.

• Excessive torque can be cause of gas leakage.

3.Connect the charging hose of the low-pressure side of manifold gauge to a gas service port as seen in the picture.

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

5.Evacuate 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) 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 4 m(24JFB) or

5 m(12/18/24JFC),A’g of refrigerant R-410A must be added for each extra meter.

If you use a pipe shorter than 4 m(24JFB) or

5 m(12/18/24JFC),The evacuating time is normal. Refer to the Service Manual for further details.
