AIR CONDITIONING 1B-15 Tighten the hose fitting to the specified torque. 5. Evacuate, charge and test the system. ACR 4 (220-240V 50/60Hz Australian model): 5-88410- 0631-0 (J-39500-220ANZ) Compression Leaks If leaks are located around the compressor shaft seal or shell, replace or repair the compressor. Recovery, Recycling, Evacuation and Charging Handling Refrigerant-134a Air conditioning systems contain R-134a. This is a chemical mixture which requires special han- dling procedures to avoid personal injury. Always wear safety goggles and protective gloves. Always work in a well-ventilated area.
Do not weld or steam clean on or near any vehicle-installed air conditioning lines or components. If R-134a should come in contact with any part of the body, flush the exposed area with cold water and immediately seek medical help. If it is necessary to transport or carry any container of R-134a in a vehicle, do not carry it in the passen- ger compartment. If it is necessary to fill a small R-134a container from a large one, never fill the container complete- ly. Space should always be allowed above the liq- uid for expansion. R-134a and R-12 should never be mixed as their compositions are not the same.
R-134a PAG oil tends to absorb moisture more quickly than R-12 mineral oil and, therefore, should be handled more carefully. N1A0067E 1. Connect the high and low charging hoses of the ACR 4 (or equivalent) as shown. 2. Recover the refrigerant by following the ACR 4 Keep R-134a containers stored below 40 ° C (100 ° F). Manufacture’s Instructions. 3. When a part is removed, put a cap or a plug on the connecting portion so that dust, dirt or moisture cannot get into it. SHOULD R-134a CONTACT YOUR EYE(S), CONSULT A DOCTOR IMMEDIATELY. DO NOT RUB THE AFFECTED EYE(S).
IN- STEAD, SPLASH QUANTITIES OF FRESH COLD WATER OVER THE AFFECTED AREA TO GRADUALLY RAISE THE TEMPERATURE OF THE REFRIGERANT ABOVE THE FREEZING POINT. OBTAIN PROPER MEDICAL TREATMENT AS SOON AS POSSIBLE. SHOULD THE R-134a TOUCH THE SKIN, THE INJURY MUST BE TREATED THE SAME AS SKIN WHICH HAS BEEN FROSTBITTEN OR FROZEN. Recycle the refrigerant recovered by ACR 4 or equiva- lent. For the details of the actual operation, follow the steps in the ACR 4 Manufacture’s Instructions. ACR 4 (115V 60Hz): 5-8840-0629-0 (J-39500-A) ACR 4 (220-240V 50/60Hz): 5-8840-0630-0 (J-39500- 220A) ACR 4 (220-240V 50/60Hz Australian model):
5-8840- 0631-0 (J-39500-220ANZ) Refrigerant Recycling Evacuation of The Refrigerant System The refrigerant must be discharged and recovered by using ACR 4 (R-134a Refrigerant Recovery/ Recycling/ Recharging/ System) (1) or equivalent before removing or mounting air conditioning parts. ACR 4 (115V 60Hz): 5-8840-0629-0 (J-39500-A) ACR 4 (220-240V 50/60Hz): 5-8840-0630-0 (J-39500- 220A) Refrigerant Recovery Notice: Explained below is a method using a vacuum pump. Re- fer to ACR 4 (or equivalent) manufacture’s instructions when evacuating the system with ACR 4 (or equivalent). Air and moisture in the refrigerant will cause problems in the air conditioning system.
Therefore, before charging the refrigerant, be sure to evacuate air and moisture thoroughly from the system. WaArRnNinIgN:G:
