7. AIR PURGING

Air and moisture in the refrigerant system may 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 refrigerant 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.

■Air Purging with a Vacuum Pump (for Test Run) Preparation

Check that each tube (both liquid and gas tubes) between the indoor and outdoor units have been properly connected and all wiring for the test run has been completed. Remove the valve caps from both the gas and liquid service valves on the outdoor unit. Note that both liquid and gas tube service valves on the outdoor unit are kept closed at this stage.

Leak test

(1)With the service valves on the outdoor unit closed, remove the 5/16" flare nut and its bonnet on the gas tube service valve. (Save for reuse.)

(2)Attach a manifold valve (with pressure gauges) and dry nitrogen gas cylinder to this service port with charge hoses.

	CAUTION	Use a manifold valve for air purging.
	CAUTION	If it is not available, use a stop valve


		for this purpose. The “Hi” knob of
		the manifold valve must always be
		kept closed.

(3)Pressurize the system to no more than 469 psig (33 kgf/cm2G) with dry nitrogen gas and close the cylinder valve when the gauge reading reaches 469 psig (33 kgf/cm2G). Then, test for leaks with liquid soap.

	CAUTION	To avoid nitrogen entering the
	CAUTION	refrigerant system in a liquid state, the


		top of the cylinder must be higher than
		the bottom when you pressurize the
		system. Usually, the cylinder is used in
		a vertical standing position.
