In all instances where the indications of refrigerant
shortage continues, additional refrigerant should be
added in
l/4 lb. increments until the sight glass is
clear.
An additional charge of l/4 lb. should be ad-
ded as a reserve. In no case should the system be
overcharged.
LEAK TESTING SYSTEM
The following two methods are recommended when attempting to locate refrigerant leaks in the system.
Loss of
regrigerant is always indicative of a leak since
refrigerant is not consumed and does not wear out.
1. Open Flame Method
- This method utilizes a gas
operated torch type leak detector (J-6084). Use of
this method is recommended when checking for
leaks in confined areas. To perform test, light torch
and adjust to obtain a pale blue flame, approximately
3/8 inch in height, in burner.
Explore for leaks by moving end of search tube
around suspected area. Check bottom of connections
since Refrigerant-12 is heavier than air and will be more apparent at underside of fittings. The flame
color will turn yellow-green when a small leak is
detected. Large leaks will turn the flame blue or
purple.
WARNING:
Do not breathe fumes resdting from
burning of
refrigerant gas. These fumes az ex-
tremeiy poisonous.
2. Liquid Leak Detectors - This method utilizes a
solution which will bubble (soap solution) to signify
a gas leak. Use of this method of checking is recom-
mended for locating small leaks.
FUNCTIONAL TESTING SYSTEM
Functional testing is a measurement of the air condi-
tioner system performance to determine if discharge
air temperature, pressure in suction line, and pres-
sure in discharge line are within specific limitations.
To perform Functional test proceed as follows:
1. Remove protective caps from the compressor
adapter fittings located on compressor.
