Heating and Air Conditioning: Service Precautions
AIR CONDITIONING SYSTEMPRECAUTION
1. DO NOT HANDLE REFRIGERANT IN AN ENCLOSED AREA OR NEAR AN OPEN FLAME
2. ALWAYS WEAR EYE PROTECTION
3. 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.

5. BE CAREFUL NOT TO DROP CONTAINER AND NOT TO APPLY PHYSICAL SHOCKS TO IT
6. 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 may burnout may occur, so take care to avoid this, necessary care should be taken.
7. DO NOT OPEN HIGH PRESSURE MANIFOLD VALVE WHILE COMPRESSOR IS OPERATING
Open and close the only low pressure valve. If the high pressure valves are opened, refrigerant flows in the reverse direction and cause the charging cylinder to rupture.
8. BE CAREFUL NOT TO OVERCHARGE SYSTEM WITH REFRIGERANT
If refrigerant is overcharged, it causes problems such as insufficient cooling, poor fuel economy, engine overheating, etc.
9. DO NOT OPERATE ENGINE AND COMPRESSOR WITH NO REFRIGERANT IS FILLED
CAUTION: This may damage the inside of the compressor because the compressor parts always moves regardless of whether the A/C system is turned on or off.
