The air conditioning system uses R-134a refrigerant and ND-OIL8 refrigerant oil, which are not compatible with R-12 refrigerant and mineral oil. Do not use R-12 refrigerant or mineral oil in this system, and do not attempt to use R-12 servicing equipment; damage to the air conditioning system or your servicing equipment will result.
Only a MVAC-trained, EPA-certified, automotive technician should service the A/C system or its components.
Air conditioning refrigerant or lubricant vapor can irritate your eyes, nose, or throat. Be careful when connecting/disconnecting service equipment.
Do not breathe refrigerant or vapor.
If accidental system discharge occurs, ventilate work area before resuming service. R-134a service equipment or vehicle air conditioning systems should not be pressure tested or leak tested with compressed air.
Compressed air mixed with R-134a forms a combustible vapor. The vapor can burn or explode causing serious injury. Never use compressed air to pressure test R-134a service equipment or vehicle air conditioning systems.
For personal protection, goggles and gloves should be worn and a clean cloth wrapped around fittings, valves, and connections when doing work that includes opening the refrigerant system. If R-134a comes in contact with any part of the body severe frostbite and personal injury can result. The exposed area should be flushed immediately with cold water and prompt medical help should be obtained.
Additional health and safety information may be obtained from the refrigerant and lubricant manufacturers.
Always disconnect the negative cable from the battery whenever replacing air conditioning parts.
Keep moisture and dirt out of the system, When disconnecting any lines, plug or cap the fittings immediately; don t remove the caps or plugs until just before you reconnect each line.
Before connecting any hose or line, apply a few drops of refrigerant oil to the O-ring.
When tightening or loosening a fitting, use a second wrench to support the matching fitting.
When discharging the system, use a R-134a refrigerant recovery/recycling/charging station; don't release refrigerant into the atmosphere.
