Refrigeration Cycle
REFRIGERANT FLOW
The refrigerant flows in the standard pattern, that is, through the compressor, the condenser, the liquid tank,
through the evaporator, and back to the compressor.
The refrigerant evaporation through the evaporator coil is controlled by an externally equalized expansion
valve, located inside the evaporator case.
FREEZE PROTECTION
The compressor cycles on and off to maintain the evaporator temperature within a specified range. When the
evaporator coil temperature falls below a specified point, the thermo control amplifier interrupts the compres-
sor operation. When the evaporator coil temperature rises above the specification, the thermo control ampli-
fier allows compressor operation.
REFRIGERANT SYSTEM PROTECTION
Dual-pressure switch
The refrigerant system is protected against excessively high or low pressures by the dual-pressure switch,
located on the liquid tank. If the system pressure rises above, or falls below the specifications, the dual-pres-
sure switch opens to interrupt the compressor operation.
Pressure relief valve
The refrigerant system is also protected by a pressure relief valve, located in the rear head of the compres-
sor. When the pressure of refrigerant in the system increases to an unusual level [more than 3,700 kPa (37.0
bar, 37.7 kg/cm
2, 537 psi)], the release port on the pressure relief valve automatically opens and releases
refrigerant into the atmosphere.

Bulb Replacement
The headlamp is a semi-sealed beam type which uses a replacable
halogen bulb. The bulb can be replaced from the engine compart-
ment side without removing the headlamp body.
IGrasp only the plastic base when handling the bulb. Never
touch the glass envelope.
1. Disconnect the battery cable.
2. Disconnect the harness connector from the back side of the bulb.
3. Pull off the rubber cap.
4. Press end of the retaining pin together to release bulb.
5. Remove the headlamp bulb. Do not shake or rotate the bulb when removing it.
6. Install the new bulb in reverse order of removal.
CAUTION:
I Do not leave headlamp reflector without bulb for a long
period of time as dust, moisture, smoke, etc. may enter the
headlamp body and affect the performance of the head-
lamp. Thus, the headlamp bulb should not be removed
from the headlamp reflector until just before a replacement
bulb is to be installed.
Aiming Adjustment
When performing headlamp aiming adjustment, use an aiming
machine, aiming wall screen or headlamp tester. For operating
instructions, of any aimer, it should be in good repair, calibrated and
used according to respective operation manuals supplied with the
unit.
For details, refer to the regulations in your own country.
Before performing aiming adjustment, check the following:
a. Keep all tires inflated to correct pressures.
b. Place vehicle and tester on one and same flat surface.
c. See that there is noload in vehicle other than coolant,
engine oil filled up to correct level, full fuel tank and the
driver (or equivalent weight placed in driver's position).
CAUTION:
Be sure aiming switch is set to ª0º when performing aiming
adjustment on vehicles equipped with headlamp aiming con-
trol.

Front Fog Lamp Aiming Adjustment
When performing fog lamp aiming adjustment, use an aiming
machine, aiming wall screen or headlamp tester. The aimer should
be in good operational condition, calibrated and used according to
the relevant operation manuals supplied with the unit.
If an aimer is not available, aiming adjustment can be done as fol-
lows:
For details, refer to the regulations in your own country.
CAUTION:
IKeep all tires inflated to correct pressures.
I Place vehicle and tester on one and the same flat surface.
I Ensure that there is no-load in the vehicle other than
coolant, engine oil (filled up to correct level), full fuel tank
and the driver (or equivalent weight placed in driver's posi-
tion).
For details of front fog lamp aiming adjustment, refer to ªAiming
Adjustmentº, EL-47.
Check the distance between the vehicle and the ground illumina-
tion point of the main axis of the fog lamp beam. Keep the distance
to approximately 40 m (131 ft).
