Heating and Air Conditioning: Service Precautions

AIR CONDITIONING: AIR CONDITIONING SYSTEM: PRECAUTION

1. CONNECT THE BATTERY NEGATIVE TERMINAL TO THE CABLE AND RUN THE ENGINE AT NO LESS THAN 2,000 RPM FOR 1 MINUTE

NOTICE:
If the engine exceeds 2,000 rpm, the clutch is automatically disengaged by the compressor protection control system.

2. DO NOT HANDLE REFRIGERANT IN ENCLOSED AREAS OR NEAR OPEN FLAMES





3. ALWAYS WEAR EYE PROTECTION

4. BE CAREFUL NOT TO GET LIQUID REFRIGERANT IN YOUR EYES OR ON YOUR SKIN





if liquid refrigerant gets in your eyes or on your skin:

(a) Wash the area with lots of cold water.

CAUTION:
Do not rub your eyes or skin.

(b) Apply clean petroleum jelly to the skin.

(c) Go immediately to a hospital or a physician for professional treatment.

5. NEVER HEAT CONTAINER OR EXPOSE IT TO NAKED FLAME

6. BE CAREFUL NOT TO DROP CONTAINER OR APPLY ANY PHYSICAL SHOCKS TO IT

7. DO NOT OPERATE COMPRESSOR WITHOUT ENOUGH REFRIGERANT IN REFRIGERANT SYSTEM





If there is not enough refrigerant in the refrigerant system, oil lubrication will be insufficient and compressor burnout may occur. Necessary care should be taken to avoid this.

8. DO NOT OPEN HIGH PRESSURE MANIFOLD VALVE WHILE COMPRESSOR IS OPERATING

Open and close only the low pressure valve. If the high pressure valve is open, refrigerant flows in the reverse direction. This could cause the charging cylinder to rupture.

9. BE CAREFUL NOT TO OVERCHARGE SYSTEM WITH REFRIGERANT

If the refrigerant is overcharged, it causes problems such as insufficient cooling, poor fuel economy and engine overheating.

10. DO NOT OPERATE ENGINE AND COMPRESSOR WITH NO REFRIGERANT

NOTICE:
This may damage the inside of the compressor.
