General information
The Ice Manger diverter valve system is designed
to direct ice from one Horizon icemaker to two ice
storage units. AUTO is the standard operating mode.
When selected, ice is directed to the lane 1 storage
unit until it reaches the MIN (minimum) set-point.
Ice is then directed to the lane 2 storage unit and
will continue to ll this lane until the FULL level is
achieved. If at any time the ice level in lane 1 storage
unit goes below the MIN set-point, ice will be directed
back to lane 1 until the MIN level is satis ed. When
lane 2 reaches its FULL level, ice will be directed back
to lane 1. When both lanes reach their FULL level, the
Horizon icemaker will shut off. After a 15-minute delay,
the icemaker will be ready to start as soon as the ice
level in either of the storage units drops below the
FULL set-point.
Audible alarm
In the event a system error occurs that could cause
ice shortages, the audible alarm will be turned ON
accompanied by an appropriate error message on the
LED screen. To silence the alarm, press any of the
push buttons on the control panel. This will silence
the alarm for 4 hours, however the error message
displayed on the LED screen will remain until the
problem is addressed. After 4 hrs, if the error has not
been addressed, the audible alarm will resume.
Placing the system in MANUAL MODE will also
prevent the alarm from sounding. The error message
on the LED screen will still ash, but the alarm will not
resume.
See troubleshooting guide on page 26 for causes.

responsibility to see that this cleaning is performed every 6 months or more often if conditions dictate. Service
problems resulting from lack of preventive maintenance will not be covered under the Follett warranty.
