Charge Refrigerant


WARNING:
- Always use HFC-134a for refregerant gas. If CFC-12 is accidentally charged, compressor is damaged due to insufficient lubrication.
- Always observe and follow precautions described on refrigerant container. Incorrect handling may result in an explosion of refrigerant container, frostbite, or the loss of eyesight.
- When charging with refrigerant gas, charge with the prescribed amount from a new service can.
- Never breathe refregerant gas and libricant vapor or mist. Exposure my irritate eyes, nose, or throat.
- Never allow HFC-134a to be exposed to an open flame or others because it generates poisonous gas when in contact with high temperature objects. Keep workshop well ventilated.
- To prevent fluorescent indicator from entering, prepare and use exclusive hose for EV (electric vehicle) and HEV (hybrid vehicle) when connecting recovery/recycling/recharging equipment.
1.Connect manifold gauge (for HFC-134a) to the service valve.
2.Connect vacuum pump to manifold gauge and operate the pump. Apply vacuum to the cooler cycle for approximately 25 minutes or longer.

CAUTION:
Evacuate air for 15 minutes or more if the parts are replaced.
3.Check the airtightness of A/C system for 25 minutes or more. If pressure raises more than the specified level, charge A/C system with approximately 200 g (0.4 lb) refrigerant and check that there is no refrigerant leakage. Refer to "Check Refrigerant Leakage" Check Refrigerant Leakage.

CAUTION:
Check the airtightness for 15 minutes or more if the parts are replaced.
4.If parts other than compressor were replaced, add compressor oil according to parts that were replaced.
Refer to "Lubricant Adjusting Procedure for Components Replacement Except Compressor" Lubricant Adjusting Procedure For Components Replacement Except Compressor.
5.Charge the A/C system from a service can with the specified amount of refrigerant.
6.Check that A/C system operates normally.
7.Disconnect the manifold gauge.
8.Install A/C service valve cap.
9.Refrigerant charge is complete.
