Evacuating the connected pipes

The outdoor unit is loaded with sufficient R410A refrigerant. You should evacuate the air in the indoor unit and in the pipe. If air remains in the refrigerant pipes, it affects the compressor. It may cause reduction of cooling capacity and malfunction.

•When installing, make sure there is no leakage. When recovering the refrigerant, ground the compressor first

CAUTION

before removing the connection pipe. If the refrigerant pipe is not properly connected and the compressor

works with the service valve open, the pipe inhales the air and it makes the pressure inside of the refrigerant

 

 

cycle abnormally high. It may cause explosion and injury.

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

• Excessive torque can be cause of gas leakage.

NOTE

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

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.

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

ffClose the valve of the low pressure side of manifold gauge clockwise. ffTurn off the vacuum pump.

ffCheck for 2 minutes if there is any pressure change.

ffRemove 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.
