HEATER AND MANUAL AIR CONDITIONER – On-vehicle Service55-12
Caution
(1) To connect the quick joint, press section “A” firmly
against the service valve until a click is heard.
(2) When connecting, run your hand along the hose
while pressing to ensure that there are no bends
in the hose.
5. Start the engine.
6. Set the blower switch to HI (Fast) position
7. Set the A/C switch to ON position
8. Set the temperature control to Max. cooling position
9. Set the mode selection to Face position
10. Set the air selection to Recirculation position
11. Fix engine speed to 1,500 r/min.
12. Check that the high-pressure side pressure is 1,667 –
1,765 kPa.
NOTE
If the pressure is not within this range, adjust it as follows;
cool down the condenser using a cooling fan if the
pressure is higher, and cover the condenser to protect
it from ventilation air if it is lower.
13. Set a dry-bulb/wet-bulb thermometer at the air inlet, and
set a dry-bulb thermometer at the air outlet.
Caution
(1) Set the dry-bulb thermometer at a position where
the temperature sensing section can be directly
blown with cooled air.
(2) Place the dry-bulb/wet-bulb thermometer at a
position where it is not exposed to cooled air
blown out.
14. After the temperature of the air blown out from the air
outlet has been stabilized (10 – 15 minutes after starting),
read the dry-bulb thermometer set at the air outlet and
the wet-valve thermometer set at the air inlet.
15. The air conditioning system is considered in good
condition if the intersecting point of the measurements
obtained in Step (14) is below the performance evaluation
reference line on the graph.
Caution
Do not remove the quick joint immediately after the
performance test has been completed. Stop the engine
and wait until the high-pressure side pressure of the
gauge manifold has been lowered sufficiently.
