8. Checking a gas leakage

(1) Connect the manifold gauge to the service port of 3-way valve.

Measure the pressure.

(2) Keep it for 5-10 minutes.

Ensure if the pressure indicated on the gauge is as same as that of measured at first time.

NOTE:

The additional gas for air purping has been charged in the outdoor unit.
However, if the flare connections have not been done correctly and there gas leaks, a gas cylinder and the
charge set will be needed.

CAUTION: Do not leak the gas in the air during Air purging, with vacumm pump are possible as you can.
