5. Air Purging
1) Air purging
• Do a leak test of all joints of the tubing(both indoor
and outdoor) and both gas and liquid side service
valves.
Bubbles indicate a leak. Be sure to wipe off the soap
with a clean cloth.
• After the system is found to be free of leaks, relieve
the nitrogen pressure by loosening the charge hose
connector at the nitrogen cylinder. When the system
pressure is reduced to normal, disconnect the hose
from the cylinder.
Air and moisture remaining in the refrigerant system
have undesirable effects as indicated below.
• Pressure in the system rises.
• Operating current rises.
• Cooling(or heating) efficiency drops.
• Moisture in the refrigerant circuit may freeze and block
capillary tubing.
• Water may lead to corrosion of parts in the refrigeration system.
Therefore, the indoor unit and tubing between the
indoor and outdoor unit must be leak tested and evacuated to remove any noncondensables and moisture
from the system.
Indoor unit
2) Air purging with vacuum pump
1. Preparation
• Check that each tube(both liquid and gas side tubes)
between the indoor and outdoor units have been properly connected and all wiring for the test run has been
completed. Remove the service valve caps from both
the gas and the liquid side on the outdoor unit. Note
that both the liquid and the gas side service valves on
the outdoor unit are kept closed at this stage.

• When the desired vacuum is reached, close the "Lo"
knob of the manifold valve and stop the vacuum pump.
4. Finishing the job
• With a service valve wrench, turn the valve stem of liquid side valve counter-clockwise to fully open the
valve.
• Turn the valve stem of gas side valve counter-clockwise to fully open the valve.
• Loosen the charge hose connected to the gas side
service port slightly to release the pressure, then
remove the hose.
• Replace the flare nut and its bonnet on the gas side
service port and fasten the flare nut securely with an
adjustable wrench. This process is very important to
prevent leakage from the system.
• Replace the valve caps at both gas and liquid side

1. Air purging (Only R-22 Model)
Required tools : hexagonal wrench, adjustable
wrench, torque wrenches, wrench to
hold the joints, and gas leak
detector.
The air in the indoor unit and in the piping must be
purged. If air remains in the refrigeration pipes, it will
affect the compressor, reduce to cooling capacity, and
could lead to a malfunction.
The additional gas for air purging has been charged
in the outdoor unit.
However, if the flare connections have not be done
correctly and there gas leaks, a gas cylinder and the
charge set will be needed.
