Leak test
1. Carry out the system evacuation and airtightness test as
described above.
2. Prepare as follows according to charging method.
Charging from service container.
Connect the refrigerant service container to the service con-
tainer valve (which is connected to the manifold gauge set air
purge valve) and open the service container.
Charging from freon recovery and recycling system.
Connect the charging valve of the system to the stop valve
(which is connected to the manifold gauge air purge valve).

3. Open the high-pressure side valve of the manifold gauge
set. Charge the system until the low-pressuer side gauge
indicates 98.1 kPa. (1 kg/cm*, 14.22 psi).
4. Close the high pressure side valve.
5. Check for leaks at the system piping joints by using a gas
leak tester.
6. If leaks are found, check the O-rings and tightening torques
at the joints. Replace or retighten as necessary.
7. If no leaks are found, fully charge the system.
Caution
l Carry out the leak test in an well-ventilated but still
air area because it is affected by moving air.

Initial charging from service container
1. Carry out the system evacuation, airtightness test, and leak
test.
2. Open the high-pressure side valve of the manifold gauge
set and charge the system as specified.
Charging amount: Approx. 400 g (14.12 oz)
3. Close the high pressure side valve.
4. Start the engine and actuate the A/C compressor.
Caution
l Do not turn the service container upside down while
charging when the engine is running.
l Do not open the high-pressure side valve while the
engine is running.
5. Open the low-pressure side valve of the manifold gauge set
and charge the system to specification.
Specified total refrigerant amount: 800 g (28.24 oz) -.

6. Close the low-pressure side valve.
7. Stop the engine.
8. Close the stop valves and the service container valve.
Caution
l Do not disconnect the stop valves or the service
container valve from the charging hoses when there
is refrigerant remaining in the hoses.
Refilling
Caution
l Do not overcharge the system.
l Note the sight glass during refilling the refrigerant.
Stop charging when no bubbles are observed in the
glass.
(Refer to page U-40).
l Care must be taken when the ambient temperature
is low. The bubbles may not be present even if the
refrigerant amount is insufficient.
1. Connect the manifold gauge set to the refrigerant system
charging valve.
(Refer to page U-32).
2. Start the engine.
3. Open the low-pressure side valve of the manifold gauge set
and charge the system as necessary.
4. Note the sight glass, and when no bubbles can be seen,
close the low-pressure side valve.
5. Stop the engine.
6. Close the stop valve and service container valve. Discon-
nect the stop valves quickly.
