When refrigerant recovery is difficult due to the large amount of refrigerant
1 Prepare manifold gauge, scale and an empty refrigerant vessel.
2 As shown below, connect the middle hose of manifold gauge to the refrigerant vessel and then connect the both
ends of manifold gauge to the outdoor unit service valve individually.
( Valve of refrigerant vessel and Low pressure side valve must be closed and the high pressure side valve
must be open.)
3 Start refrigerant recovery operation by pressing K2 button three times. (Refer to page 36.)
4 After operating for 10 minutes, open the valve of refrigerant vessel and fill it with refrigerant.
5 Close the valve of refrigerant vessel when sufficient refrigerant is filled.
6 Close the liquid service valve immediately. When the low pressure falls down lower than 0, close the gas service
valve.
7 Stop the operation by pressing reset button.
