Charge
CAUTION!
• Because the sight glass is not used for this A/C system, do not perform an additional
charge to the A/C system. To charge the
proper amount of refrigerant, recover and
evacuate the A/C system first. And then,
charge the proper amount of refrigerant
into the A/C system.
• Always charge refrigerant through low pressure side of A/C system after the initial
charge is performed from the high
pressure side with the engine stopped.
• Never charge refrigerant through high pressure side of A/C system with engine
running.
• Do not charge refrigerant while compressor is hot.
• When installing tap valve to refrigerant container to make a hole there through,
carefully follow dire ctions given by
manufacturer.
• A pressure gauge should always be used before and during refrigerant charge.
• 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 refrigerant
charge. 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 recycling refrigerant),
follow the procedure described in the
equipment manufacturer’s instruction
manual.

Charge proper amount of refrigerant accurately in
accordance with the following procedure.
Specified amount of refrigerant
370 ± 20 g (13.0 ± 0.7 oz)
The initial charge of the A/C system is performed
through 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 if 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.
Then, open refrigerant 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.
WARNING!
Make sure that high pressure side valve is
closed securely.

5) Start engine and keep engine speed at 1500 r/min, and then operate A/C system.
6) Charge A/C system with refrigerant in vapor state. At this time, refrigerant container should be held
upright.

7) When refrigerant container (1) is emptied, use the following procedure to replace it with a new
refrigerant container.
a) Close low pressure valve.
b) Replace empty container with a refrigerant container which has been charged with
refrigerant. When using refrigerant container tap
valve (2), use the following procedure for
replacement.
i) Retract needle (3) and remove refrigerant container tap valve by loosening its plate nut
(4).
ii) Install the refrigerant container tap valve to a new refrigerant container.
c) Purge any air existing in center charging hose. When using refrigerant container tap valve, use
the following procedure to purge air.
i) Once fully tighten refrigerant container tap valve (1), and then loosen (open) plate nut
(2) slightly.
ii) Open low pressure side valve (3) of manifold
gauge set (4) a little.
iii) As soon as refrigerant comes out with a “hiss” through a clearance between
refrigerant container and tap valve, tighten
plate nut as well as low pressure side valve.
iv) Turn handle of tap valve clockwise so that its needle is screwed into the new container to
make a hole for refrigerant flow. 8) After the system has been charged with specified
amount (370 ± 20 g) of refrigerant or when low
pressure gauge (1) and high pressure gauge (2)
have indicated the following specified value, close
low pressure side valve (3) on manifold gauge set
(4).

Removal of Manifold Gauge Set
WARNING!
High pressure side is under high pressure.
Therefore, be careful not to get injured
especially on your eyes and skin.

For the A/C system charged with the specified amount of
refrigerant, remove manifold gauge set as follows:
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 quickly.
5) Put caps on service valves.
Check A/C System for Refrigerant Leaks
Whenever a refrigerant leak is suspected in the system
or any service operation has been performed which may
result in malfunction of lines and connections, it is
advisable to check for leaks.
Common sense should be used during 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 detector
WARNING!
• To prevent explosions and fires, make sure that there are no flammables in the vicinity.
• When the refrigerant exposed to fire, it turns into a poisonous gas (phosgene). Do
not inhale this gas.

There is a number of fittings and places throughout the
A/C 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 condenser, an electronic (refrigerant) leak detector
is more practical fo r determining leaks.
