Recommended lubricants quickly absorb moisture from the atmosphere. When servicing the air conditioner, the following precautions must be observed:
When dismantling parts of the system from the vehicle, immediately close them with plugs (seals) to reduce the penetration of atmospheric moisture into parts.
When installing parts of the air conditioner on the car, do not remove the plugs (seals), until other parts are connected. Connect all parts of the air conditioning circuit as quickly as possible to reduce the penetration of moisture into the system.
Use only recommended grease in unopened containers. Close the grease container immediately after use. Loosely sealed grease will become saturated with moisture and cannot be used in the future.
Do not allow grease to come into contact with foam parts. This may damage them.
Avoid open ventilation of the air conditioning circuit and do not expose the oil to steam or moisture. The discharge may irritate the eyes, nose, and throat. Use only approved refrigerant recycling/replacement equipment to bleed the refrigerant system. If a refrigerant leak occurs, thoroughly ventilate the area before proceeding. Additional health and safety information is available from refrigerant and lubricant manufacturers.
Do not release refrigerant into the atmosphere. Use approved refrigerant recovery/replacement equipment to capture refrigerant while it is being discharged from the system.
When working with any refrigerants or any air conditioning systems, always wear safety goggles and gloves to protect your eyes and hands.
Do not heat the refrigerant container (including storage) up to temperatures above 52°C.
Do not expose the refrigerant container to an open flame; if the container needs to be heated, place the bottom of the container in a bucket of hot water.
Do not intentionally throw, pierce or burn the refrigerant container.
Keep refrigerant away from open flame. Combustion of the refrigerant produces poisonous gas.
The refrigerant displaces oxygen and must be handled in a well-ventilated area to prevent asphyxiation.
During repair work, do not check the tightness of the service equipment and (or) vehicle air conditioning systems, and checking for refrigerant leaks using compressed air. In certain proportions, the mixture of air and refrigerant becomes combustible at high pressure. If ignited, this mixture can cause injury and serious damage. Additional health and safety information can be obtained from refrigerant manufacturers.
