[55A] HEATER, AIR CONDITIONER AND VENTILATION - - ON-VEHICLE SERVICE - PERFORMANCE TEST | PRINT PAGE / INDEX / PRIOR / NEXT

| PERFORMANCE TEST The vehicles to be tested should be in a place that is not in direct sunlight.
| Close the high and low-pressure valve of the gauge manifold. 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. 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 the A/C pipe and the low-pressure service valve is on the suction hose. 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. Start the engine. 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 Adjust engine speed to 1,500 r/min with A/C clutch engaged. Engine should be warmed up with doors and windows opened.
| 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. Note the discharge air temperature.
