Not wide-ranged A/C type But refrigerant type. Before connecting to the system, please check whether the pressure gauge pointer is in the zero position, otherwise open the screw to adjust the pointer to zero position. First close the low pressure valve, high pressure valve. After interface connecting with blue tube(Iow voltage fast connector), and then locking to system low pressure. After interface connecting with the red tube(low voltage fast connector), and then locking to the system high pressure.

Interface connecting with yellow tube and vacuum pump. (Note:this step must be carried out under the system pressure, otherwise it should be advanced relief pressure).

Open the vacuum pump, high and low pressure valve, and the system begins to draw a vacuum. After a certain period of time(10-30min), check whether the system is completely vacuum, otherwise the vacuum should be repaired and vacuum again.

Close the high and low pressure valves at the same time, and close the vacuum pump. Put the yellow tube and vacuum pump away. After run the system test(about 5-10min), check the system pressure and temperature. If the refrigerant is insufficient, open the low pressure valve slowly(it is prohibited to open high pressure valve), and add proper amount of refrigerant. If it is too high, you should turn off the cylinder, open the high pressure valve slowly, discharge amount of refrigerant(at this point should pay attention to the discharge of refrigerant wounding) and close the high pressure valve, and retest until normal.

After running normal, close the refrigerant bottle and valves, and then put high and low voltage fast connectors away(pay attention to high temperature). Package List(2 Sets for Your Choice).
