  1. With manifold gauge set connected, attach refrigerant container to hose on center connector of manifold gauge set. Fully open refrigerant container valve, and purge air from center hose.
  2. Disconnect electrical connector from clutch cycling pressure switch located on the accumulator. Install jumper wire between clutch cycling pressure switch connector terminals.
  3. Open low-side valve on manifold gauge set, and allow refrigerant to enter system. When refrigerant is no longer being drawn into system, start and operate engine. Place A/C-heater controls on maximum cold position with blower fan on high speed.
    NOTE: In areas where ambient air temperature is high, it may be necessary to operate a high output fan to blow air through condenser and radiator.
  4. When proper amount of refrigerant has been added, close low-side valve on manifold gauge set. Remove jumper wire, and connect clutch cycling pressure switch. Reinstall electrical connector.
  5. Operate system to verify proper operation and normal system pressures. Disconnect manifold gauge set. Install service port caps. Check system for leaks.
