PERFORMANCE TEST


1.The vehicles to be tested should be in a place that is not in direct sunlight.

2.Close the high and low-pressure valve of the gauge manifold.
3.Connect the charging hose (blue) to the low-pressure valve and connect the charging hose (red) to the high-pressure valve of the gauge manifold.
4.
caution
  • To connect the quick joint, press section A firmly against the service valve until a click is heard.
  • When connecting, run your hand along the hose while pressing to ensure that there are no bends in the hose.
Install the quick joint (for low-pressure) to the charging hose (blue), and connect the quick joint (for high-pressure) to the charging hose (red).
note The high-pressure service valve is on the A/C pipe and the low-pressure service valve is on the suction hose.
5.Connect the quick joint (for low-pressure) to the low-pressure service valve and connect the quick joint (for high-pressure) to the high-pressure service valve.
6.Start the engine.
7.Set the A/C controls as follows:
When the front A/C test
  • A/C switch: A/C - ON position
  • Mode selection: FACE position
  • Temperature control: MAXIMUM COOLING position
  • Air selection: RECIRCULATION position
  • Blower switch:Fast position
When the rear A/C test
  • The front A/C should be set as above
  • A/C switch: A/C ON position
  • Temperature control: MAXIMUM COOLING position
  • Blower switch:Fast position
8.Adjust engine speed to 1,500 r/min with A/C clutch engaged.
9.Engine should be warmed up with doors and windows opened.


10.Insert a thermometer in the centre air outlet and operate the engine for 20 minutes.
note If the clutch cycles, take the reading before the clutch disengages.
11.Note the discharge air temperature.
