1B-24 AIR CONDITIONING (OPTIONAL)
Removing manifold gauge set
WARNING:
High pressure side is naturally under high pressure. So, care must be used to protect your eyes and
skin.
When A/C system has been charged with a specified amount of refrigerant, remove manifold gauge set as fol-
lows:
1) Close low pressure side valve of manifold gauge set. (The high pressure side valve is closed continuously
during the process of charging.)
2) Close refrigerant container valve.
3) Stop engine.
4) Using shop rag, remove charging hoses from service valves. This operation must be performed rapidly.
5) Put caps on service valves.
Leak test
Whenever a refrigerant leak is suspected in the system or any
service operation has been performed which may result in dis-
turbing lines or connections, it is advisable to test for leaks.
Common sense should be used in performing any refrigerant leak
test, since the need and extent of any such test will, in general,
depend upon the nature of a complaint and the type of a service
performed on the system.
LIQUID LEAK DETECTORS
WARNING:
• To prevent explosions or fires, make sure that there
are no flammables in the vicinity.
• When exposed to fire, the refrigerant turns into a poi-
sonous gas (phosgene). Do not inhale this gas.
There are a number of fittings and places throughout the air con-
ditioning system where a liquid leak detector solution may be
used to pinpoint refrigerant leaks.
By merely applying the solution to the area in question with a
swab, such as attached to the cap of a vial, bubbles will form
within seconds if there is a leak.
For confined areas, such as sections of the evaporator and con-
denser, an electronic (refrigerant) leak detector is more practical
for determining leaks.
