been shown to be combustible at elevated pressures. These mixtures, if ignited, may cause injury or
property damage. Additional health and safety info rmation may be obtained from refrigerant manu-
facturers.
Oil PrecautionINFOID:0000000005396477
• Use only specified oil for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components. If oil
other than that specified is used, comp ressor malfunction is likely to occur.
• The specified HFC-134a (R-134a) oil rapidly absorbs moisture from the atmosphere. The following handling
precautions must be observed:
- When removing refrigerant components from a vehicle, immediately cap (seal) the component to minimize the entry of moisture from the atmosphere.
- When installing refrigerant components to a vehicle, do not remove the caps (unseal) until just before con- necting the components. Connect all refrigerant loop components as quickly as possible to minimize the
entry of moisture into system.
- Only use the specified oil from a sealed container. Imm ediately reseal containers of oil. Without proper seal-
ing, oil will become moisture saturated and should not be used.
• Avoid breathing A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose and throat.
Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a) refrigerant. If accidental
system discharge occurs, ventilate work area before resuming service. Additional health and safety informa-
tion may be obtained from refrigerant and oil manufacturers.
• Do not allow A/C oil to come in contact with styrofoam parts. Damage may result.
Precaution for Refrigerant ConnectionINFOID:0000000005396478
A new type refrigerant connection has been introduced to a ll refrigerant lines except the following location.
• Expansion valve to evaporator
• Refrigerant pressure sensor to condenser
FEATURES OF NEW TYPE REFRIGERANT CONNECTION
• The O-ring has been relocated. It has also been provided with a groove for proper installation. This elimi-
nates the chance of the O-ring being caught in, or damaged by, the mating part. The sealing direction of the
O-ring is now set vertically in relation to the contacti ng surface of the mating part to improve sealing charac-
teristics.
• The reaction force of the O-ring will not occur in the direction that causes the joint to pull out, thereby facili- tating piping connections.

PRECAUTIONS
MR18DE - TYPE 1 and HR16DEMR18DE - TYPE 2
WARNING:
Make sure all refrigerant is discharged into the recycling equipment and the pressure in the system is
less than atmospheric pressure. Then gradually loo sen the discharge side hose fitting and remove it.
CAUTION:
The new and former refrigerant connections use different O-ring configurations. Do not confuse O-
rings since they are not interchangeable. If a wrong O-ring is installed, refrigerant will leak at, or
around, the connection.

CAUTION:
When replacing or cleaning refrigerant cycle components, observe the following.
• When the compressor is removed, store it in the sam e position as it is when installed on the vehicle.
Doing so will cause oil to en ter the low-pressure chamber.
• When connecting tubes, always use a to rque wrench and a back-up wrench.
• After disconnecting tubes, immediately plug all op enings to prevent entry of dirt and moisture.
• When installing an air conditione r in the vehicle, connect the pipes as the final stage of the opera-
tion. Do not remove the seal caps of pipes and other components until just before required for con-
nection.
• Allow components stored in cool areas to warm to working area temperature before removing seal
caps. This prevents condensation from forming inside A/C components.
• Thoroughly remove moisture from the refrigeration system before charging the refrigerant.
• Always replace used O-rings.
• When connecting tube, apply the speci fied A/C oil to circle of the O-rings. Be careful not to apply oil
to threaded portion. Refer to MTC-96, "
Oil".
• O-ring must be closely attached to dented portion of tube.
• When replacing the O-ring, be careful not to damage O-ring and tube.
• Connect tube until you hear it cl ick, then tighten the nut or bolt by hand until snug. Make sure that
the O-ring is installed to tube correctly.
• After connecting line, perform leak test and make sure that there is no leakage from connections.
When the refrigerant leaking point is found, disconnect that line and replace the O-ring. Then tighten
connections of seal seat to the specified torque.

PREPARATION
HFC-134a (R-134a) Service Tool and EquipmentINFOID:0000000005396482
Never mix HFC-134a refrigerant and/or its specified oil with CFC-12 (R-12) refrigerant and/or its oil.
Separate and non-interchangeable service equipment must be used for handling each type of refrigerant/oil.
Refrigerant container fittings, service hose fittings and service equipment fittings (equipment which handles
refrigerant and/or oil) are different between CFC-12 (R-12) and HFC-134a (R-134a). This is to avoid mixed
use of the refrigerants/oil.
Adapters that convert one size fitting to another must never be used refrigerant/oil contamination will occur
and compressor failure will result.

OIL
Maintenance of Oil Qu antity in CompressorINFOID:0000000005396487
The oil in the compressor circulates through the system with the refrigerant. Add oil to compressor when
replacing any component or after a large refrigerant leakage occurred. It is important to maintain the specified
amount.
If oil quantity is not maintained properly , the following malfunctions may result:
• Lack of oil: May lead to a seized compressor.
• Excessive oil: Inadequate cooling (thermal exchange interference)
OIL
OIL ADJUSTING PROCEDURE FOR COMPONENTS REPLACEMENT EXCEPT COMPRESSOR
After replacing any of the following major components, add the correct amount of oil to the system.
Amount Of Oil To Be Added
