Precautions for Working with
R-134a
• R-12 refrigerant and R-134a refrigerant are not
compatible. These refrigerants must never be mixed,
even in the smallest amounts. If the refrigerants are
mixed, compressor failure is likely to occur.
• Use only specified lubricant for the R-134a A/C system
and R-l34a components. If lubricant other than that
specified is used, compressor failure is likely to occur.
• The specified R-134a lubricant rapidly absorbs moisture
from the atmosphere.
The following handling precautions must be observed:
1. When removing refrigerant components from a vehicle,
immediately cap (seal) the component to minimize
the entry of moisture from the atmosphere.
2. When installing refrigerant components to a vehicle,
do not remove the caps (unseal) until just before
connecting the components. Connect all refrigerant
loop components as quickly as possible to minimize
the entry of moisture into system.
3. Only use the specified lubricant from a sealed
container. Immediately reseal containers of lubricant.
Without proper sealing, lubricant will become moisture
saturated and should not be used.
4. Avoid breathing A/C refrigerant and lubricant vapor or
mist. Exposure may irritate eyes, nose and throat.
Use only approved recovery/recycling equipment to
discharge R-134a refrigerant. If accidental system
discharge occurs, ventilate work area before resuming
service. Additional health and safety information may
be obtained from refrigerant and lubricant
manufacturers.
5. Do not allow lubricant to come in contact with
Styrofoam parts. Damage may result.

General Refrigerant Precautions

• Do not release refrigerant into the air. Use approved
recovery/recycling equipment to capture the refrigerant
every time an air conditioning system is discharged.
• Always wear eye and hand protection (goggles and
gloves) when working with any refrigerant or air
conditioning system.
• Do not store or heat refrigerant containers above 52°C.
• Do not heat a refrigerant container with an open flame:
if container warming is required place the bottom of
the container in a warm pail of water.
• Do not intentionally drop, puncture, or incinerate
refrigerant containers.
• Keep refrigerant away from open flames: poisonous
gas will be produced if refrigerant burns.
• Refrigerant will displace oxygen, therefore be certain
to work in well ventilated area to prevent suffocation.
• Do not introduce compressed air to any refrigerant
container or refrigerant component.

Handling O-Ring

1. Even though O-rings may look identical, it is extremely
important that only recommended service
replacement air conditioning O-rings be used, or
excessive leakage of the refrigerant may occur.
2. Always O-ring and installation area should be kept
clean. Any foreign material and dust may result in
excessive refrigerant leakage.
3. Before installation, verify that both O-ring and fittings
have not been nicked or deformed. Deformed or nicked
parts must be replaced.
4. Failure to use the proper service replacement parts
and procedures may result in excessive refrigerant
leakage.

Handling Refrigerant

1. Always work in a well-ventilated area.
2. If you have difficulty breathing, seek medical attention
immediately. If refrigerant comes in contact with any
part of your body, flush the exposed area with water.
If a rush or pain develops seek medical attention.
