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.
Evacuating the connected pipes
1. Connect each assembly pipe to the appropriate valve on the outdoor unit and
tighten the are nut.
2. Tighten the are nut rst 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.

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 o 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.

The outdoor unit is loaded with sucient R22 refrigerant .You should evacuate the air in the indoor unit and in the pipe.If air
remains in the refrigerant pipes, it aects the compressor. It may cause reduction of cooling capacity and malfunction.
