When the machine is pumping down the operator interface will indicate “PUMPING DOWN”.
During the pumpdown sequence the compressor is running and the liquid feed valve (A-Valve) is
closed. The machine will complete one harvest cycle then the compressor will continue to run until
the freezer pressure reaches the low pressure safety switch setting. The pumpdown sequence will
move most of the refrigerant from the freezer to the receiver for servicing operations. It is
recommended that the king valve be closed during servicing of the ice machine.
