If accidental system discharge occurs, ventilate work area before resuming service. Additional health and safety information may be obtained from the refrigerant and lubricant manufacturers.
- Connect a R-134a refrigerant recover/recycling/charging station (A) to the high-pressure service port (B) and the low-pressure service port (C), following the equipment manufacturers instructions.
- Add the same amount of new refrigerant oil to the system that was removed during recovery.
- Charge the system with the specified amount of R-134a refrigerant. Do not overcharge the system; the compressor will be damaged.
Charge 17.65 + / - 1.05 oz. (500 + / - 30 g). The initial charge of the A/C system is performed from the high pressure side with the engine stopped. And next, this method must be followed by charging from the low pressure side with the engine running.
- Check to make sure that hoses are routed properly after evacuating the system.
- Connect Low charging hose (1) and High charging hose (2) of the manifold gauge set (3) in position. Thus, open refrigerant container valve (4) to purge the charging line.
- Open the high pressure side valve (5) and charge refrigerant to system.
After a while, open the low pressure side valve (6) and close the high pressure side valve (5).
WARNINGMake sure that high pressure side valve is closed securely.
- Start engine and keep engine speed at 1500 r/min. Then, operate air conditioning at -DEF- or -DEF/FOOT- air flow mode.
Charge A/C system with refrigerant. At this time, refrigerant container (4) should be held upright.
Remove manifold gauge set as follows:
WARNINGHigh pressure side is naturally under high pressure. So, care must be taken to protect your eyes and skin.
- Close low pressure side valve of manifold gauge set. (The high pressure side valve is closed continuously during the process of charging.)
- Close refrigerant container valve.
- Stop engine.
- Using shop rag, remove charging hoses from service valves. This operation must be performed rapidly.
- Put caps on service valves.
