Discharging, Adding Oil, Evacuating, and Charging Procedures for A/C System: Notes
WARNING:
Use only refillable refrigerant tanks that are authorized for the charging station being used. The use of other tanks may cause personal injury or void the warranty.
WARNING:
To avoid personal injury, always wear goggles and gloves when performing work that involves opening the refrigeration system.
A charging station discharges, evacuates, and recharges an air-conditioning (A/C) system with one hookup. Filtering the refrigerant during the recovery cycle together with filtering during the evacuation cycle ensures a supply of clean, dry refrigerant for A/C system charging.
CAUTION:
- Never use the R-134a charging station on a system charged with R-12. The refrigerants and the oils from each system are not compatible with those from the other system and must never be mixed, even in the smallest amount. Mixing refrigerant residue will damage the equipment.
- Never use adapters which convert from one size fitting to another. Such use allows contamination, which may cause system failure.
