AIR CONDITIONING 39 11.16 SAFETY TIPS FOR AC SYSTEM Never handle refrigerant without eye protection goggles. Don’t take chances. Never discharge vapour from the system into an area where there is flame. Never close the compressor discharge valve whilst the compressor is operating. Discharge the air conditioning system slowly. Never weld or steam clean on or near the system. Doing so can result in dangerous pressure build up in a closed system and a possible rupture may occur. Be careful when working near exposed evaporator or condenser fins. Painful cuts can be inflicted by these fins. Keep your hands clear of the engine and belts while the engine is running. Installing Hoses and Fittings 1. Always use Refrigerant Oil not Motor Oil to lubricate ID and OD of hoses and fittings before installation 2. Use only refrigerant hose and fittings. When installing new hose on old fittings, use same type of hose to ensure proper mating of hose and fittings
