Check that the engine and A/C are stopped. 2. Close the high-pressure valve of the gauge manifold. 3. Connect the charging hose (red) to the hi-pressure side of the gauge manifold. 4. Connect the quick joint (for high pressure) to the charging hose (red). 5. Install the quick joint (for high pressure) to the high-pressure side service valve of the vehicle. 6. Close the low-pressure valve of the gauge manifold. 7. Connect the charging hose (blue) to the low-pressure side of the gauge manifold. 8. Connect the quick joint (for low pressure) to the charging hose (blue). 9. Install the quick joint (for low pressure) to the low-pressure side service valve of the vehicle. 10.Start and fully warm up the engine, and then check that the engine speed of the test condition 11.Set the A/C control panel to the mode instructed in the test conditions. 12.Measure the high pressure/low pressure, and check that the measurement is within the |
