7 Operation When the air-conditioning is serviced, the engine and the air-conditioning must be switched off. 7.1 Recovery 1. First fit the connections of the Air-Con Service Station to the vehicle air conditioning system and open them. 2. Check for the high and low pressure gauges. If the pressure is equal to zero or lower, it shows that no refrigerant leaves in the air-conditioning system, you can select other selections directly.
4. About 5 seconds later, oil draining finished. RECOVERY FINISHED! PRESS STAR TO CONFIRM! 5. Press key to stop the buzzer, then recovery process finished! 7.2 Vacuum 1. After recovery you had better to wait for about 1minute, if the A/C system raise continue to recovery, if the A/C system pressure didn’t rises above zero, press key, the device enter vacuum process.
VACUUM FIN ISHED P RESS START TO CON FIRM! 4. wait about five minutes .and check the low pressure gauge indicator, if the pressure is raising, you need confirm whether the air-conditioning’s leakage. If leakage, you should repair it. If not, continue the next process. 7.3 Oil injection 1.
2. Press key to enter the refrigerant filling quantity. Either use the value shown on the filling quantities sticker in the vehicle and enter it using the keypad and the cursor keys, or press use the Air-Con Service Station’s database. 3.
