CHARGING
A6E851478834W02
Caution
• Do not exceed the specification when charging the system with refrigerant. Doing so will decrease
the efficiency of the air conditioner or damage the refrigeration cycle parts.

1. Connect an R-134a recovery/recycling/recharging device to the vehicle and follow the device manufacturer's
instructions.
Charging Preparation
1. Install the SSTs (gas charging set).
2. Connect the tap pin side of the SST (49 C061 004) to the air purge valve of the SST (49C061 001).
3. Connect the SST (49 C061 005) to the center joint of the SST (49 C061 001).
4. Connect the SST (49 C061 005) to the vacuum pump.
5. Connect the SST (49 C061 004) to the refrigerant tank.
6. Place the refrigerant tank on the scale.
