Performance Test

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




1. Close the high and low-pressure valve of the gauge manifold.
2. 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.
3. 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).

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.

NOTE: The high-pressure service valve is on A/C pipe and the low-pressure service valve is on the suction hose.

4. 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.
5. Start the engine.
6. Set the A/C controls as follows:
- A/C switch: A/C - ON position
- Mode selection: FACE position
- Temperature control: MAXIMUM COOLING position
- Air selection: RECIRCULATION position
- Blower switch: "4" (Fast) position

7. Adjust engine speed to 1,500 r/min with A/C clutch engaged.
8. Engine should be warmed up with doors and windows closed.




9. Insert a thermometer in the center air outlet and operate the engine for 20 minutes.

NOTE: If the clutch cycles, take the reading before the clutch disengages.
