AIR CONDITIONING SYSTEM

PRECAUTION
1 . Do not handle refrigerant inside enclosed space or nearby open fire.
2 . Protective glasses must be worn.
3 . Be careful not to have eyes or skin exposed to liquid refrigerant.
04
If eyes or skin are exposed to liquid refrigerant:
(a) Rinse them with cold water with plenty of water.
(b) Apply clean vaseline onto the skin.
(c) Seek medical advice immediately or reach a hospital for professional treatment.
4 . Do not heat up a container or have it exposed to open fire.
5 . Do not allow a container to drop off or to be subjected to impact.
6 . Do not allow the compressor to work if there is not enough refrigerant inside
the refrigeration system.
Lack of refrigerant inside the air conditioning system may cause inadequate lubrication
and damage to compressor.
7 . Do not open the high pressure manifold valve when the compressor works.

(a) Open and close the low pressure valve only.
If the high-pressure valve is opened, the refrigerant may back flow and lead to fracture
of the charging cylinder.

8 . Do not add too much refrigerant into the system.
(a) Too much refrigerant might cause the problems such as poor refrigeration performance,
poor fuel economy, and engine superheating etc.
9 . Do not run the compressor when refrigerant is not available.
