1. DISCHARGE REFRIGERANT FROM REFRIGERATION SYSTEM HINT: At the time of installation, refer to the following: Evacuate air from the refrigeration system. Charge the system with refrigerant and inspect for leakage of refrigerant. Specified amount: Single A/C: 750 +/- 50 g (26.45 +/- 1.76 oz.) Dual A/C: 1050 +/- 50 g (37.03 +/- 1.76 oz.)
2. REMOVE PRESSURE SWITCH FROM LIQUID TUBE Disconnect the connector and remove the pressure switch. Torque: 10 N.m (100 kgF.cm, 7 ft.lbf) HINT: Being careful not to deform the tube, lock the switch mounted on the tube with an open end wrench and remove the switch. At the time of installation, refer to the following: Lubricate a new O-ring with the compressor oil and install it to the switch.
