3) Low Water Control

The  icemaker  will  stop  when  the  water  level  in  the  Reservoir  falls  below  the  lower 

float level and is not refilled to the upper float level within 90 seconds due to either an 

interruption  in  the  water  supply  or  low  water  pressure.  When  the  water  reaches  the 

upper float level, the icemaker will automatically resume the icemaking process.
