Note:
- Use only the HFC-134a (R-134a) sensor kit.
- Use a vacuum pump adapter with a built-in one-way valve to prevent oil from the pump from entering the system.
Warning
When working with refrigerant HFC-134a (R-34a):
- Always wear eye protection.
- Avoid contact with skin or eyes.
If this happened, then:
-Do not rub your skin or eyes.
- Rinse eyes or skin with plenty of cold water.
-Contact a doctor or medical facility for immediate help, do not try to help yourself.
- Store containers containing HFC-134a (R-134a) refrigerant at temperatures below 40°C.
- Keep away from open flames, the refrigerant itself is not flammable, but releases toxic gases when in contact with flame.
- Work in a well-ventilated area. The refrigerant evaporates very quickly and can displace all the air in a small, enclosed space.
Caution: Do not overcharge the system, as this will damage the compressor.
1. After checking for leaks, make sure the high pressure valve is closed and start the engine.
Note: Engine speed must be below 1500 rpm.

2. Open the front door.
Turn A/C to ON.
Set the temperature control to MAX.
Set the mode switch to VENT.
Turn on the heater fan to MAX.
3. Open the low pressure valve and charge R-134a refrigerant.
Warning
- Do not open the high pressure valve.
- Do not turn containers upside down.
4. Charge the system with a specified amount of refrigerant.
Amount of refrigerant: 650 g.
5. After charging the specified amount, close the low pressure valve and refrigerant tanks. Check the system.
6. Stop the engine and quickly disconnect the charging hose.
7. Check the system for leaks using a gas detector for R-134a refrigerant.
Note: Check for leaks randomly around the compressor, condenser and tank/dryer.
