Refrigerant Line
• Never use heat for bending pipes. When bending a pipe , try to make its bending angle as smooth as possible.
• Keep internal parts of air conditioning free from moistu re and dirt. When disconnecting any line from system, install
a blind plug or cap to the fitting immediately.
• When connecting hoses and pipes, apply a few drops of compressor oil (refrigerant oil) to O-ring.
• When tightening or loosening a fitting, use two wrenches, one for turning and the other for support.
• When handling recovery and recycling equipment, be sure to follow the instruction manual for the equipment.
• Check local governmental regulations regarding working with refrigerator systems and its tooling.
• Route drain hose so that drained water does not make any contact to vehicle components.
• If pipes or hoses are replaced, replenish specified amount of compressor oil to compre ssor suction side referring to
“Replenishing Compressor Oil” in “Operation Procedure for Refrigerant Charge”.
Refrigerant Recovery
When discharging refrigerant out of A/C system, always recover it by using refrigerant recovery and recycling
equipment because discharging refrigerant HFC-134a (R-1 34a) into atmosphere would cause adverse effect to
environments.
NOTE
When handling recovery and recycling equipment, be sure to follow the instruction manual for the
equipment.

Refrigerant Charge
After performing compressor oil replenishment and evacuat ion, charge a proper amount of refrigerant to A/C system
referring to “Charge” in “Operation Procedure for Refrigerant Charge”.

Evacuation
CAUTION!
Do not evacuate before recovering
refrigerant in A/C system.

NOTE
Once air conditioning system circuit is
opened (exposed) to atmospheric air, system
must be evacuated by using a vacuum pump.
The A/C system should be attached with a
manifold gauge set, and should be evacuated
for approximately 15 minutes.

1) Connect high charging hose (1) and low charging hose (2) of manifold gauge set (3) respectively as
follows:
High charging hose → High pressure charging valve
(4) on condenser outlet pipe
Low charging hose → Low pressure charging valve
(5) on suction pipe
2) Attach center charging hose (6) of manifold gauge set to vacuum pump (7).
3) Operate vacuum pump, and then open discharge
side valve (Hi) (8) of manifold gauge set.
If there is no blockage in the system, there will be an
indication on high pressure gauge (9).
In this case, open the other side valve (Lo) (10) of
the set and repair the system.
4) Approximately 10 minutes later, low pressure gauge (11) should show a vacuum lower than –100 kPa (–
1.0 kg/cm
2, –760 mmHg, –14.7 psi) providing no
leakage exists.
NOTE
• If the system does not show a vacuum below –100 kPa (–1.0 kg/cm
2, –760 mmHg,
–14.7 psi), close both valves, stop vacuum
pump and watch movement of low
pressure gauge.
• Increase in the gauge reading suggests existence of leakage. In this case, repair
the system before continuing its
evacuation.
• If the gauge shows a stable reading (suggesting no leakage), continue
evacuation.

5) Evacuation should be carried out for a total of at least 15 minutes.
6) Continue evacuation until low pressure gauge indicates a vacuum less than –100 kPa (–1.0 kg/cm
2,
–760 mmHg, –14.7 psi), and then close both valves.
7) Stop vacuum pump. Disconnect center charging hose from pump inlet. No w, the system is ready for
charging refrigerant.
Checking A/C System for Pressure Leaks
After completing the evacuation, close manifold gauge
high pressure valve and low pressure valve and wait 10
minutes. Verify that low pressure gauge reading has not
changed.
CAUTION!
If the gauge reading moves closer to “0”,
there is a leak somewhere. Inspect the tubing
connections and make necessary
corrections. And then, evacuate system once
again and make sure that there are no leaks.

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.

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.
