Charging Station Method

Follow charging instructions provided with the charging station in use. If the equipment is not General Motors approved follow these exceptions:
1. Do not connect the high side service valve to the air conditioning system.
2. Keep the high pressure valve on the charging station dosed at all times.
3. Perform the entire charge procedure through the low side pressure service port on the suction pipe.
4. Following these procedures will prevent accidental high side vehicle system pressure being subjected to the charging station in the event an error is made in valve closing sequence during compressor operation to pull in the R-134a charge.
