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.

System circuit diagram/connector diagram
l These show the circuits for each system, from the power supply to the ground. The power supply side
is on the upper part of the page, the ground side on the lower part. The diagrams describe circuits with
the ignition switch off.
Below is an explanation of the various points in the diagram.
