Removal and Installation of Dual-pressure SwitchEJS00289
REMOVAL
1. Use a refrigerant collecting equipment (for HFC-134a) to discharge the refrigerant.
2. Remove liquid tank. Refer to ATC-156, "
Removal and Installation of Liquid Tank" .
3. Using a vise, secure liquid tank, and remove dual-pressure
switch.
INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:

Apply compressor oil to O-ling of dual pressure switch when installing it.

When recharging refrigerant, check for leaks.
Removal and Installation of EvaporatorEJS000VG
REMOVAL
1. Use a refrigerant collecting equipment (for HFC-134a) to discharge the refrigerant.
2. Remove extension cowl top panel.
3. Disconnect low-pressure flexible hose and high-pressure pipe
from evaporator.
CAUTION:
Cap or wrap the joint of low-pressure flexible hose and
high-pressure pipe with a suitable material such as a vinyl
tape to avoid the entry of air.
4. Remove mounting screws, and then remove expansion valve
cover.
5. Remove mounting bolts, and then remove expansion valve.
6. Remove blower unit. Refer to ATC-125, "
BLOWER UNIT" .

3. Check if the A/C refrigerant pressure is at least 345 kPa (3.45 bar, 3.52 kg/cm2 , 50 psi) above 16°C
(61°F). If less than specification, recover/evacuate and recharge the system with the specified amount of
refrigerant.
NOTE:
At temperatures below 16°C (61°F), leaks may not be detected since the system may not reach 345 kPa (3.45
bar, 3.52 kg/cm
2 , 50 psi).
4. Perform the leak test from the high-pressure side (compressor discharge a to evaporator inlet g) to the
low-pressure side (evaporator drain hose h to shaft seal k). Refer to ATC-143, "
Components" . Perform a
leak check for the following areas carefully. Clean the component to be checked and move the leak
detected probe completely around the connection/component.
Compressor
Check the fitting of high- and low- pressure hoses, relief valve and shaft seal.
Liquid tank
Check the refrigerant pressure sensor or dual pressure switch.
Service valves
Check all around the service valves. Ensure service valve caps are secured on the service valves (to pre-
vent leaks).
NOTE:
After removing A/C manifold gauge set from service valves, wipe any residue from valves to prevent any
false readings by leak detector.
Cooling unit (Evaporator)
With engine OFF, turn blower fan on “High” for at least 15 seconds to dissipate any refrigerant trace in the
cooling unit. Wait a minimum of 10 minutes accumulation time (refer to the manufacturer’s recommended
procedure for actual wait time) before inserting the leak detector probe into the drain hose.
Keep the probe inserted for at least 10 seconds. Use caution not to contaminate the probe tip with water
or dirt that may be in the drain hose.
5. If a leak detector detects a leak, verify at least once by blowing compressed air into area of suspected
leak, then repeat check as outlined above.
6. Do not stop when one leak is found. Continue to check for additional leaks at all system components.
If no leaks are found, perform steps 7-10.
7. Start engine.
8. Set the heater A/C control as follows;
a. A/C switch: ON
b. Mode control dial: VENT (Ventilation)
c. Intake position: Recirculation
d. Max. cold temperature
e. Fan speed: High
9. Run engine at 1,500 rpm for at least 2 minutes.
10. Turn engine off and perform leak check again following steps 4 through 6 above.
Refrigerant leaks should be checked immediately after stopping the
engine. Begin with the leak detector at the compressor. The pres-
sure on the high-pressure side will gradually drop after refrigerant
circulation stops and pressure on the low-pressure side will gradually
rise, as shown in the graph. Some leaks are more easily detected
when pressure is high.
11. Discharge A/C system using approved refrigerant recovery equipment. Repair the leaking fitting or com-
ponent if necessary.
12. Evacuate and recharge A/C system and perform the leak test to confirm no refrigerant leaks.
