11. Liquid Push / Pull Mode
When recovering more than 10 kg of liquid refrigerant, Push/Pull Mode is
recommended.
An electric scale needs to be used together with the recovery
unit to monitor the recover process. Once the siphon is started, it
can overfill the recovery tank. The siphon can continue even if the
machine is turned off. You must manually close the valves on the
tank and the unit to prevent overfilling.
1. Turn the switch to position "1".
2. Correctly and firmly connect the hoses (see connection diagram).
3. Turn the power on to start the unit.

slowly, it means that the liquid recovery is finished, and it is time for gas
recovery (The hoses need to be reconnected and please follow the
purge operation to purge the gas refrigerant).
7. Close the gas valve on the refrigerant tank and then turn the power off.
