1B-24 AIR CONDITIONING (OPTIONAL)
CHARGING
CAUTION:
• Always charge through low pressure side of A/C system at after the initial charging is performed
from the high pressure side with the engine stopped.
• Never charge to high pressure side of A/C system with engine running.
• Do not charge while compressor is hot.
• When installing tap valve to refrigerant container to make a hole there through, carefully follow
directions given by manufacturer.
• A pressure gauge should always be used before and during charging.
• The refrigerant container should be emptied of refrigerant when discarding it.
• The refrigerant container should not be heated up to 40°C (104°F) or over.
• Refrigerant container should not be reversed in direction during charging. Reversing in direction
causes liquid refrigerant to enter compressor, causing troubles, such as compression of liquid
refrigerant and the like.
NOTE:
The air conditioning system contains HFC-134a (R-134a).
Described here is a method to charge the air conditioning system with refrigerant from the refrigerant
service container.
When charging refrigerant recovered by using the refrigerant and recycling equipment (when recy-
cling refrigerant), follow the procedure described in the equipment manufacturer's instruction man-
ual.
CHARGING PROCEDURE
The initial charging of the A/C system is performed from the high
pressure side with the engine stopped.
And next, this method must be followed by charging from the low
pressure side with the engine running.
1) Check to make sure that hoses are routed properly after
evacuating the system.
2) Connect Low charging hose (1) and High charging hose (2)
of the manifold gauge set (3) in position. Thus open refriger-
ant container valve (4) to purge the charging line.
3) Open the high pressure side valve (5) and charge refrigerant
to system.
4) After a while, open the low pressure side valve (6) and close
the high pressure side valve (5).
WARNING:
Make sure that high pressure side valve is closed
securely.
5) Start engine and keep engine speed at 1500 r/min. Then,
operate air conditioning.
6) Charge A/C system with refrigerant in vapor state. At this
time, refrigerant container (4) should be held upright.
