7. NEVER HEAT CONTAINER OR EXPOSE THE CONTAINER TO AN OPEN FLAME
8. BE CAREFUL NOT TO DROP CONTAINER OR APPLY PHYSICAL SHOCKS TO IT
10. DO NOT OPEN HIGH PRESSURE MANIFOLD VALVE WHILE COMPRESSOR IS OPERATING
(a) Open and close only the low pressure valve.
If the high pressure valve is opened, refrigerant flows in the reverse direction causing the charging cylinder to
rupture.
11. 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.
12. DO NOT OPERATE COMPRESSOR WITHOUT REFRIGERANT
CAUTION:
Doing so may damage inside the compressor because the compressor parts always move regardless of whether
the A/C system is turned on or off.
13. PRECAUTIONS TO BE OBSERVED WHILE SERVICING
CAUTION:
Always use electric insulating gloves and remove the service plug grip before beginning inspection, as
inspection of the A/C system requires disconnecting high voltage connectors.

(b) Apply clean petroleum jelly to the skin.
(c) Go immediately to a hospital or see a physician for professional
treatment.
9. DO NOT OPERATE COMPRESSOR WITHOUT ENOUGH
REFRIGERANT IN AIR CONDITIONING SYSTEM
If there is not enough refrigerant in the A/C system, oil lubrication will be
insufficient and the compressor may be damaged.
Necessary care should be taken to avoid this.
