VII. REPAIRING DEVICES WHICH ARE EXCLUSIVE - USE FOR HFC-134a REFRIGERANT This refrigerator use Compressor with Ester Oil. Ester Oil employed as new compressor oil for refrigerant HFC-134a. Ester Oil is characteristic of higher hygroscopicity. When moisture leaks into the refrigerating unit, it will chemically react with the moisture and solid substance clogging the pipe will form. -

IX. TOOLS FOR REPAIRING REFRIGERATING UNIT HFC-134a Caution: Conventional repairing devices for CFC-12 can not connect with repairing devices for HFC-134A. Because the shape of fitting for HFC-134A (M10 x P1.5 mm) is different from conventional ones. Be sure connect the adaptor with vacuum pump, so it that the vacuum pump can be used for both CFC- 12 and HFC-134a. -

- Page 12 Check pressure at High Pressure side Install Pierching Plier with Pressure Gauge at Discharge near Compressor, then check pressure from compressor running. If Compressor stop, start compressor again about ± 5 minute until stabile pressure, then check pressure Note: Before measuring, make sure the Pressure Gauge at " 0 " position. If not at " 0 " position, adjust the Screw at Pressure Gauge.

- Page 14 High pressure side Connect the process - tube - fitting with the inlet pipe of dryer by wrenches. Note: Do not purge the pipe at high - pressure side from compressor side so that no deteriorated oil can flow into the condenser. Connect the charge cylinder (for HFC-134a) with the process - tube - fitting.
- Page 15 7. ASSEMBLING THE COMPRESSOR AND THE DRYER General Clause a. It should be finished within 30 minutes. When pipe purging no need From the process of removing compressor until the process of setting compressor and dryer (just before vacuum pumping process). When pipe purging has need From the time just after pipe cleaning is completed until the process of setting compressor and dryer (just before vacuum pumping process).
- Page 16 8. VACUUM PUMPING General Clause: Vacuum pumping should be done more than 60 minutes from 2 portions. One portion at high - pressure side and one portion at low - pressure side. Be sure the Adaptor good connect to vacuum pump. The Adaptor can stop oil flow from Vacuum Pump to Cooling Unit HFC-134a, after Manifold Gauge and Charge Hose vacuum condition.

MEMASUKKAN REFRIGERANT DARI CYLINDER KEDALAM CHARGE CYLINDER REFRIGERANT CHARGING FROM CYLINDER TO INSIDE OF CYLINDER CHARGE Preparation: Before vacuum pumping process, it should charging the refrigerant from Cylinder HFC-134a to inside of Cylinder Charge. Connect Cylinder Charge and Control Valve. Fit the Adaptor Charge at Cylinder HFC-134a.
- Page 18 5. Close quickly the valve as soon as the set amount is charged. Set the starting Relay and the overload protector. And run the compressor until pressure reading at the low pressure gauge shows 0 so that remaining refrigerant in the charge hose is taken in the refrigerating unit.
