Discharging, Adding Oil, Evacuating and Charging

J 23500-01 Service Charging Station:

Charging The System With Refrigerant Drum:

DISCHARGING, ADDING OIL, EVACUATING AND CHARGING
The refrigerant system may be discharged, evacuated and charged using air conditioning service charging station J 23500-01 or equivalent, or the manifold and gage set J 23575-01 and drum 13.6 Kg (30 lb.) of Refrigerant-12.

Charging lines from the charging station or manifold and gage set requires the use of gage adapters to connect to the system service fitting. A straight gage adapter J 5420 and a 90° angle gage adapter J 9459 (or J 25498A and J 25499A) are available (see Special Tools).

Always wear goggles and wrap a clean cloth around fittings and connections when doing work that involves opening the refrigeration system. If liquid refrigerant comes into contact with the skin or eyes, injury may result.
^ Before removing and replacing any of the air conditioning refrigeration lines or components, the system must be completely discharged of Refrigerant-12.
^ Always use service valve and charging station equipment or pressure gage sets during evacuation and charging procedures.
^ Always discharge system at low-side service fitting and perform the entire evacuating and charging procedure through the low-side service fitting.
^ Do not connect high pressure line or any line to the high-side service fitting during discharging and charging procedures.

CAUTIONS
- Never remove a gage line from its adapter when line is connected to A/C system.
- Always remove the line adapter from the service fitting to disconnect a line.
- Do not remove charging hose at gage set while attached to service low-side fitting. This will result in complete discharge of system due to the depressed Schrader valve in service low-side fitting and may cause personal injury due to escaping Refrigerant-12.
