Heating and Air Conditioning: Service Precautions

PRECAUTION




1. DO NOT HANDLE REFRIGERANT IN AN ENCLOSED AREA OR NEAR NAKED 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 cool 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 THE CONTAINER OR EXPOSE IT TO NAKED FLAME
5. BE CAREFUL NOT TO DROP THE CONTAINER OR APPLY PHYSICAL SHOCKS TO IT




6. DO NOT OPERATE THE COMPRESSOR WITHOUT ENOUGH REFRIGERANT IN THE 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.

7. DO NOT OPEN HIGH PRESSURE MANIFOLD VALVE WHILE COMPRESSOR IS OPERATING
If the high pressure valves are opened, refrigerant flows in the reverse direction and could cause the charging cylinder to rupture. Open and close only the low pressure valve.

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

CAUTION: Doing so may damage the inside of the compressor because the compressor parts always move regardless of whether the A/C system is turned on or off.

10. SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
The LEXUS LS430 is equipped with an SRS (Supplemental Restraint system) such as the driver, front passenger, side, curtain shield air bags etc.. Failure to carry out service operation in the correct sequence could cause the SRS to unexpectedly deploy during servicing, possibly leading to a serious accident. Before servicing (including removal or installation of parts, inspection or replacement), be sure to read the precautionary notices.

11. PRECAUTION FOR DISCONNECTING THE BATTER CABLE






NOTE: When disconnecting the negative (-) battery terminal, initialize the system shown in the table after the terminal is reconnected.
