PRECAUTION
1. DO NOT HANDLE REFRIGERANT IN AN ENCLOSED
AREA OR NEAR AN OPEN FLAME
2. ALWAYS WEAR SAFETY GLASSES FOR EYE
PROTECTION
3. AVOID YOUR EYES AND SKIN TO CONTACT WITH
LIQUID REFRIGERANT
If you get the liquid refrigerant in your eyes or on your skin:
(a) Wash out 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 physician or hospital for professional
treatment.
4. NEVER HEAT CONTAINER OR EXPOSE IT TO NAKED
FLAME
5. DO NOT DROP CONTAINER NOR 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 lu-
brication will be insufficient and compressor burnout may occur.
To avoid this, always keep enough refrigerant in the refrigerant
system.
7. DO NOT OPEN HIGH PRESSURE MANIFOLD VALVE
WHILE COMPRESSOR IS OPERATING
If the high pressure valves opened, refrigerant flows in the re-
verse direction and could cause the charging cylinder to rup-
ture, so open and close the only low pressure valve.
8. DO NOT OVERCHARGE REFRIGERANT SYSTEM
WITH REFRIGERANT
If refrigerant is overcharged, it causes problems such as insuffi-
cient cooling, poor fuel economy, engine overheating etc.
