After2-3minutes, operation stops. Close the three-
way valve (gas) within one minute after operations
stops.
The LED will go out three minutes after it stops.Dis-
connect the power supply after confirming that the
LED has gone out.
*When the pump down operation is repeated, temporarily disconnect
the power supply after opening the closed valves (both liquid and gas).
Reconnect the power supply after2-3minutes and perform the pump
down operation.
*When the start of the operation after pump down operation has been
completed, temporarily disconnect the power supply after opening the
