6.1 Connection diagram
6.2 Ready for operation
Connect the pipes correctly and firmly. (Please refer to the connection diagram)
Make sure all valves are closed.
1. Switch off the power of refrigerant equipment.
2. 0pen the vapour and liquid valves of refrigerant equipment.
3. Open the vapour valve of the refrigerant tank.
5.3 Start operation
4. Turn the switch to the position “START”.
5. Press button.
6. a. Open the liquid valve for liquid recovery.
b. Open the vapour valve for vapour recovery.
7. Turn the switch slowly to position “2” for faster recovery.
8. When the recovery is finished, the unit gets the needed vacuum or automatically stop with low pressure
protection.
NOTE
1. If compressor impact occurs at the position “2”, turn the switch to position “START” until the impact
stops.
2. lf the recovery restarts after interruption of power or difficult to start:
a. Turn the switch to position “START”, turn on the power switch, press start button for liquid recovery.
b. Turn the switch to position “3”, turn on the power switch, press start button for vapour recovery.
NOTE
1. Turning the switch to position”1” gets a stable recovery of liquid with low speed of 1.2Kg/min.
2. lf compressor impact occurs at the position “1·, turn the switch slowly to position “STAR” until the
impact stops. Make sure the pressure is not at 0 bar, because it doesn’t work at O bar.
There is no need to turn off the power and it can do the self-purge work directly.
