8.  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 refriger-
ant system

Therefore, the indoor unit and tubing between the
indoor and outdoor unit must be leak tested and evac-
uated 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 has been prop-

erly connected and all wiring for the test run has been

completed. Remove the valve caps from both the gas

tube and liquid tube 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) Attach a manifold valve (with pressure gauges)

and dry nitrogen gas cylinder to this service port

with charge hoses. 

(2) Pressurize the system to no more than 36 kgf/cm

2

G

with dry nitrogen gas and close the cylinder valve

when the gauge reading reaches 36 kgf/cm

2

G.

Then, test for leaks with liquid soap.

Use a manifold valve for air

purging. If it is not available,

use a stop valve for this pur-

pose. The “Hi” knob of the

manifold valve must always

be kept closed.

CAUTION

CAUTION

To avoid nitrogen entering

the refrigerant system in a

liquid state, the top of the

cylinder must be higher than

the bottom when you pres-

surize the system. Usually,

the cylinder is used in a ver-

tical standing position.
