1. Connect each assembly pipe to the appropriate valve on the outdoor unit and
2.
applying the following torque:
t When installing, make sure there is no leakage. When recovering the refrigerant, ground the compressor
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.

t Excessive torque can be cause of gas leakage.
The outdoor unit is loade erant for a 5-meter pipe.
You should purge the air in the indoor unit and in the pipe.
If air remains in the refrigerant pipes, it ects the compressor. It may cause
reduction of cooling capacity and malfunction.

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. Purge the air in the connected pipes using the vacuum pump for about
15 minutes.
u
Make sure that pressure gauge shows -0.1MPa(-76cmHg) after about
10 minutes.
This procedure is very important to avoid a gas leak.
u
Close the valve of the low pressure side of manifold gauge clockwise.
u
u
Check for 2 minutes if there is any pressure change.
u
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.
7. Mount the valve stem nuts and the service port cap to the valve, and tighten
them at the torque of 183kgftcm with a torque wrench.
8. Check for a gas leak paying particular attention to the 3-way valve’s stem nuts
and to the service port cap (Refer to page 35.
