Charging the System

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).








1. Open the high-pressure side valve of the manifold gauge set.
Charge the system until the low-pressure side gauge indicates 98.1 kPa (14.22 psi).
2. Close the high-pressure side valve.
3. Check for leaks at the system piping joints by using a gas leak tester.
4. If leaks are found, check the 0-rings and tightening torques at the joints. Replace or retighten as necessary.
5. If no leaks are found, fully charge the system.

Caution: Carry out the leak test in an well-ventilated but still air area because it is affected by moving air.


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.

First Charge
Refrigerant 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
^ Do not turn the service container upside down while charging when the engine is running.
^ 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.

Second charge
Refrigerant amount: Approx. 400 g (14.12 oz)
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: 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:
^ Do not overcharge the system.
^ Note the sight glass during refilling of the refrigerant. Stop charging when no bubbles are observed in the glass.
^ 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.
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 valves and service container valve. Disconnect the stop valves quickly.
