AIR CONDITIONING 1B-17 N1A0070E Legend 1. Charge valve handle 3. Vacuum pump 2. Service container Direct charging with a manifold gauge charging station method Handling the charging valve handle when installing refrigerant container. 1. Before attaching the charge valve to the refrigerant container, turn the charge valve handle (1) coun- terclockwise until the needle (2) is fully retracted. 2. Turn the plate nut (3) counterclockwise until it reaches its highest position relative to the charge valve. 3. Install the charge valve onto the refrigerant con- tainer (4). 4. Turn the plate nut clockwise and connect the cen- ter hose of the manifold gauge to the charge valve (5). 5.
Tighten the plate nut sufficiently by hand. Then turn the charge valve handle clockwise to lower the needle and bore a hole in the refrigerant container. 6. Turn the charge valve handle counterclockwise to raise the needle. The refrigerant in the refrigerant container is charged into the air conditioning sys- tem by the operation of the manifold gauge. Be absolutely sure not to reuse the emptied refrig- erant container.
