Operation
General information
The Ice Manger diverter valve system is designed to
direct ice from one Horizon ice machine 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 ice machine will shut off. After a 15-minute
delay, the ice machine 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.

Cleaning and preventive maintenance
Preventive maintenance
Periodic cleaning of Follett’s Ice Manager diverter valve system is required to ensure peak performance and delivery
of clean, sanitary ice. Cleaning of the Ice Manager system, in most cases, should be performed by your facility’s
maintenance staff or a Follett authorized service agent. Regardless of who performs the cleaning, it is the operator’s
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.
Weekly exterior care
The exterior of the diverter valve and control panel may be cleaned with a soft cloth and mild detergent. The ice
machine exterior may be cleaned with a stainless cleaner such as 3M Stainless Steel Cleaner & Polish or equivalent.
Note: Do not use bleach to sanitize or clean the ice machine or diverter valve.
WARNING
• Wear rubber gloves and safety goggles (and/or face shield) when handling ice machine cleaner or sanitizer
CAUTION
• Use only Follett approved SafeCLEAN™ cleaner (item# 00132001) and NU-CALGON IMS-II SANITIZER.
• Do not mix cleaner and sanitizer solutions together
• DO NOT USE BLEACH
• It is a violation of Federal law to use these solutions in a manner inconsistent with their labeling
• Read and understand all labels printed on packaging before use
Note: Complete procedure for cleaning and sanitizing MUST be followed in order shown. Ice must be collected for
10 minutes from each lane before putting ice machine and Ice Manager system back into service.

20 Ice Manager Diverter Valve System Operation and Service Manual
Service
System components
Follett’s Ice Manager diverter valve system consists of following major components:
• Diverter valve module
• Control panel module
• Ice transport tube lane 1 with a dedicated sensor cable 1
• Ice transport tube lane 2 with a dedicated sensor cable 2
• Ice level sensor / ice distribution module for lane 1
• Ice level sensor / ice distribution module for lane 2
System operation
The Ice Manager diverter valve system is designed to control the feeding of ice from one Horizon ice machine to two
ice storage units. There are different ice level set-points for ice storage units.
The ice storage unit for lane 1 has two ice level set points, MIN and FULL, while the ice storage unit for lane 2 has
only one - FULL. There is also a DIF (Differential) setting for each lane that initiates rell of ice.
Note: Ice Manager diverter valve system comes with factory pre-set values for MIN, FULL and DIF (differential)
parameters. If required the pre-set values can be eld modied. (See the ice level set point on page 25.)
Control logic
Ultrasonic sensors for lane 1 and lane 2 detect ice level and send an analog signal between 0.5vdc to 4.5vdc back to
diverter valve control board. This signal is converted into distance (in inches) from the sensor face to the ice surface.
An appropriate light on the control panel comes on indicating the ice level reached either MIN or FULL levels for
lane 1 or FULL level for a lane 2 units.
Auto mode
AUTO is the standard operating mode for the Ice Manager diverter valve system. In AUTO mode, the system will
automatically direct the ice according to the sensor set point levels.
On start up, when AUTO mode is selected the diverter valve directs ice through lane 1 to the ice storage unit until the
MIN level is satised.
The diverter valve will then switch and direct ice through lane 2 until its ice storage unit FULL level is satised.
If during this time the ice level in lane 1 ice storage unit drops below the MIN level, then the diverter valve will
re-direct ice ow back to lane 1 and continue feeding ice through the lane 1 until the ice storage unit MIN level is
satised again. The cycle will continue until FULL level for both ice storage units are reached.
When the ice level in both ice storage units is at the FULL level the diverter valve shuts off the signal to the ice
machine which goes into a 15 min delay. When the delay period expires, the control logic will allow the ice machine to
restart when either sensor detects ice level drop below the FULL set-point.
Note: There is a 30 second time delay function programmed into the control logic. This function requires
30 seconds of a steady ice level reading exceeding a set-point before the control logic initiates any action.
Therefore, a momentary ice level change measured by the ice level sensors will not trigger a shut-down
or divert.
Manual mode
For Ice Manager diverter valve system cleaning and sanitizing, and some special situations (see a troubleshooting
guide on page 26), a MANUAL mode is available. MANUAL mode overrides AUTO mode and allows the operator to
select the lane.
In order to switch between AUTO and MANUAL modes push the MODE SELECT button located on the control panel.
While in MANUAL mode, pressing either lane 1 or lane 2 buttons will divert ice ow accordingly.
Note: When in manual mode ice level sensors will not control the divert action, however the ice sensors will
continue to control the ice machine. When the FULL ice level in designated ice storage unit is satised the
ice machine will be shut off.
