8.7. Air purging of the piping and indoor unit

8.7.1. Air purging

The air which contains moisture is remaining in the refrigeration cycle may cause malfunction on the compressor.
1. Remove caps from the 2-way and 3-way valves.
2. Remove the service-port cap from the 3-way valve.
3. To open the valve, turn the valve stem of 2-way valve counter-clockwise approximately 90° and hold it there for 10 seconds,

then close it.

4. Check a gas leakage of the connecting portion of the piping.

5. Set the both 2-way and 3-way valves to open position with the hexagonal wrench for the unit operation.
