Charging procedure
Charge proper amount of refrigerant accurately in accordance with the following procedure.
Specified amount of refrigerant
500 +/- 30 g (17.65 +/- 1.05 oz)
The initial charging 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).WARNING: Make 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:
WARNING:
High 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.
