27. Remove the quick joint 2 from the low-pressure service
valve.
28. Remove the service can.
NOTE
If the service can is not emptied completely, keep the
handles of the charging valve and adaptor valve 1 closed
for the next charging.
REFRIGERANT CHARGING AMOUNT CHECK
1. Start the engine.
2. Operate A/C and set the temperature control to MAX
COOL.
3. Fix the engine speed at 1,500 r/min.
4. Check the refrigerant level (bubble generation) through
the sight glass of the receiver.
ItemCondition
Proper levelBubbles are generated some times. No
bubbles appear when the engine speed is
slightly increased.
Level too lowA large amount of air bubbles are generated. If
it looks milky white, the level is excessively
lowered.
Level too highNo air bubbles appear.
5. If the level is too low, add the refrigerant, and if the level
is too high, drain the refrigerant as necessary.
Caution
Be sure to work at the low-pressure side service valve.

REPLENISHING SYSTEM
1. Connect the charging hose (blue) to the adapter valve
1 with the handle fully turned back (valve closed).
2. Connect the charging hose (blue) to the quick joint 2
and to the low pressure service valve.
Caution
Never connect to the high-pressure side since
otherwise the refrigerant could flow back.
3. Open and close the valve by operating the handle of
the adapter valve 1 to bleed air from inside the charging
hose.
4. With the handle turned back all the way (valve open),
install the charging valve to the service van.
5. Tighten the handle of the charging valve (valve closed)
and puncture the service can.
6. Install the charging valve to the adapter valve 1 and turn
back the handle all the way (valve open).
7. Start the engine.
8. Operate the A/C and set to the lowest temperature (MAX.
COOL).
9. Fix the engine speed at 1,500 r/min.
10. Tighten the handle of the adapter valve 1 (valve open).
Replenish the system with refrigerant while checking the
level through the sight glass.
After charging with refrigerant, turn the handles of the
charging valve and the adapter valve 1 all the way back
(valve closed), then remove the quick joint 2.
NOTE
If the service can is not emptied completely, keep the
handles of the charging valve and adaptor valve closed
for the next charging.Charging

DISCHARGING SYSTEM
1. Run the engine at an engine speed of 1,200–1,500 r/min
for approximately 5 minutes with the A/C operating to
return to the oil.
NOTE
Returning the oil will be more effective if it is done while
driving.
2. Stop the engine.
3. Connect the charging hose (blue) to the adaptor valve
1 with its handle turned back all the way (valve closed).
4. Connect the quick joint 2 to the charging hose (blue),
and install the quick joint to the low-pressure service valve.
NOTE
The low-pressure service valve is provided on the suction
pipe.
Caution
(1) To connect the quick joint, press section “A” firmly
against the service valve until a click is heard.
(2) When connecting, run your hand along the hose
while pressing to ensure that there are no bends
in the hose.
5. Place the adaptor valve 1 inside the container and
discharge the refrigerant by opening the handle gradually
so that oil does not gush out.
NOTE
Any oil remaining in the container should be returned
to the A/C system.
PERFORMANCE TEST
1. The vehicle to be tested should be placed in a place
that is not exposed to direct sunlight.
2. The ambient condition should be 16 – 30 °C in temperature
and 60 – 100 % in relative humidity.
3. Open all the doors so that the air condition inside the
passenger compartment may be identical to that of the
outside.
4. With the high-pressure side of the gauge manifold closed,
connect the charging hose (red) to the gauge manifold
high-pressure side. Attach the quick joint for high-pressure
to the charging hose (red) and install it to the high-pressure
service valve on the vehicle side.
NOTE
The high-pressure service valve is found on liquid pipe
