Precaution for Working with HFC-134a (R-134a)

INFOID:0000000005147600

WARNING:

• CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. If the refrigerants

are mixed compressor failure is likely to occur. Refer to 

HA-4, "Contaminated Refrigerant"

. To deter-

mine the purity of HFC-134a (R-134a) in the vehicle and recovery tank, use recovery/recycling  equip-

ment and refrigerant identifier.

• 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, compressor failure 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 connecting 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. Immediately reseal containers of oil. Without

proper sealing, 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.

Remove HFC-134a (R-134a) from the A/C system using certified service equipment meeting require-

ments of SAE J2210 [HFC-134a (R-134a) recycling equipment], or J2209 [HFC-134a (R-134a) recovery

equipment]. If accidental system discharge occurs, ventilate work area before resuming service.

Additional health and safety information 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 Procedure without Cowl Top Cover

INFOID:0000000005147601

When performing the procedure after removing cowl top cover, cover

the lower end of windshield with urethane, etc.

FUNCTION DIAGNOSIS

IN-CABIN MICROFILTER

Description

INFOID:0000000005147603

FUNCTION

The air inside the passenger compartment is filtered by the in-cabin

microfilters when the heater or A/C controls are set on either the

recirculation or fresh mode. The two in-cabin microfilters are located

in the front heater and cooling unit assembly. The rear heater and

cooling unit assembly only draws in air from the passenger compart-

ment to recirculate into the passenger compartment, so the rear

heater and cooling unit assembly is not equipped with in-cabin

microfilters.

REPLACEMENT TIMING

Replacement of the two in-cabin microfilters is recommended on a regular interval depending on the driving

conditions. Refer to 

MA-9, "Introduction of Periodic Maintenance"

. It may also be necessary to replace the two

in-cabin microfilters as part of a component replacement if the in-cabin microfilters are damaged.

REPLACEMENT PROCEDURE

1. Remove the glove box assembly from the instrument panel. Refer to 

IP-17, "Removal and Installation"

.

2. Remove the screw and remove the in-cabin microfilter cover as

shown.

3. Remove the two in-cabin microfilters from the front heater and

cooling unit assembly housing.

4. Insert the first new in-cabin microfilter into the front heater and

cooling unit assembly housing and slide it over to the right.

Insert the second new in-cabin microfilter into the front heater

and cooling unit assembly housing as shown.

NOTE:

The in-cabin microfilters are marked with air flow arrows. The

end of the microfilter with the arrow should face the rear of the

vehicle. The arrows should point downward.

5. Install the in-cabin microfilter cover.

6. Install the glove box assembly in the instrument panel. Refer to
