EVACUATING AND CHARGING PROCEDURES

Before opening any refrigerant hose or component, read the information furnished in:

- Refrigerant Operating Characteristics.

- Discharging, Evacuating, Adding Oil and Charging Procedures.

Remove sealing caps from subassemblies before making connections for final assembly. Use a small amount of clean 525 viscosity refrigerant oil on all tube and hose joints.

Use new seal (O-ring) dipped in the clean 525 viscosity refrigerant oil when assembling joints. The oil will aid in assembly and help provide a leak-proof joint.

When tightening joints, use a second wrench to hold the stationary part of the connection.

Tighten all tubing connections (see accompanying figure). Insufficient or excessive torque can cause loose joints or deformed joint parts. Either condition can cause leakage.

CHARGING PROCEDURES

Tools Required:

- J 5420 Straight Gage Adaptor
- J 5453 Safety Goggles
- J 9459 900 Gage Adapter
- J 23500-01 Portable Charging Station
- J 23575-01 Complete Manifold Assembly
- J 29547 Autobalance Refrigerant Leak Detector

Discharge, evacuate and charge using J 23500-01, or J 23575-01 and J 6272-02, which uses four 0.397 kg (14 oz.) disposable cans of Refrigerant-12.

Use gage adapters to connect the charging lines from the charging station or manifold and gage set to system service fittings. A straight gage Adapter J 5420 and a 900 angle gage Adapter J 9459 is available.

Wear J 5453 Safety Goggles and wrap a clean cloth around fittings and connections.

- Discharge the system before removing and replacing refrigeration lines or components.

- Use the service valve and pressure gage sets during evacuation and charging procedures.

- Do not charge while the compressor system is hot.

- Always discharge the system at the low side service fitting and perform the entire evacuation and charging procedure through the low side service fitting.

- Do not connect the high pressure line or any line to the high side service fitting during discharging and charging procedures.

WARNING: Never remove a gage line from its adapter when the line is connected to the 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 discharge the system due to the depressed schrader valve in service low side fitting and may cause personal injury due to escaping Refrigerant-12.
