Operation

Cleaning/sanitizing and preventive maintenance (all models)

Note: Do not use bleach to sanitize or clean the icemaker.

Preventive maintenance

Periodic cleaning of Follett’s icemaker system is required to ensure peak performance and delivery of clean,
sanitary ice. The recommended cleaning procedures that follow should be performed at least as frequently as
recommended, and more often if environmental conditions dictate.

Cleaning of the condenser can usually be performed by facility personnel. Cleaning of the icemaker 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
according to the schedule below. Service problems resulting from lack of preventive maintenance will not be
covered under the Follett warranty.

Weekly exterior care

The exterior may be cleaned with a stainless cleaner such as 3M Stainless Steel Cleaner & Polish or equivalent.

Monthly condenser cleaning (air-cooled icemaker only)

1. Use a vacuum cleaner or stiff brush to carefully clean condenser coils of air-cooled icemakers to ensure

optimal performance.

2. When reinstalling counter panels in front of remote icemakers, be sure that ventilation louvers line up with
condenser air duct.

Semi-annual evaporator cleaning (every 6 months)

WARNING

• Wear rubber gloves and safety goggles (and/or face shield) when handling ice machine cleaner or sanitizer.

CAUTION

• Use only Follett approved SafeCLEAN Plus™ cleaning solution.

• 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. Ice must be collected for

10minutes before putting ice machine back into service.

1. Press the CLEAN button. The machine will drain. The

auger will run for a short time and then stop. Wait for
the LOW WATER light to come on.

2. Follow the directions on the SafeCLEAN Plus
packaging to mix 1 gal. (3.8 L) of Follett SafeCLEAN
Plus solution. Use 100 F (38 C) water.

3. Using a 1 quart (1L) container, slowly ll cleaning cup
until CLEANER FULL light comes on. Do not overll.

4. Soak one SaniSponge™ in remaining sanitizing and
cleaning solution and retain for Step 9.

Note: Do not use bleach to sanitize or clean the icemaker.

5. Replace cover on cleaner cup. Machine will clean,

then ush 3 times in approximately 15 minutes. Wait
until machine restarts.

Service

Ice machine operation (all models)

Follett’s ice machine consists of ve distinct functional systems covered in detail as follows:

§ Water system

§ Electrical control system

§ Mechanical assembly

§ Refrigeration system

§ Bin full

The Horizon ice machine overview

The Follett Horizon ice machine uses a horizontal, cylindrical evaporator to freeze water on its inner surface. The
refrigeration cycle is continuous; there is no batch cycle. The evaporator is ooded with water and the level is
controlled by sensors in a reservoir. A rotating auger continuously scrapes ice from the inner wall of the evaporator.
The auger moves harvested ice through the evaporator into an ice extrusion canal. The ice is forced through a
restrictive nozzle that squeezes out the water and creates the Chewblet. The continuous extrusion process pushes
the Chewblets through a transport tube into a dispenser or bin.

A solid state PC board controls and monitors the functionality of the ice machine. In addition to sequencing
electrical components, the board monitors various operational parameters. A full complement of indicator lights
allows visual status of the machine's operation. Additionally, the PC board controls the self-ushing feature of the
ice machine. The evaporator water is periodically drained and replenished to remove minerals and sediment.

A unique “bin full” detection system is incorporated in the Horizon ice machine. A switch located at the ice
discharge port of the machine detects the position of the transport tube. When the bin lls up with ice, the transport
tube moves out of the normal running position, and the switch turns the ice maker off. A domed housing at the end
of the transport tube contains the ice extrusion loads during shut down.

“Bin full” detection system

The Follett Horizon ice machine incorporates a unique “bin full” detection system that consists of the shuttle and
actuator. The shuttle incorporates a ag and switch. Referencing the gure below, the normal running position
of the ag is down, and the switch is closed. When the bin lls to the top and ice can no longer move through
the tube, the machine will force the shuttle ag up, opening the switch and shutting the machine off. The shuttle
actuator, located above the ice bin allows the ice to curl up within it when the bin is full. In this way, there are no
loads generated that would tend to lift off the lid of the bin.
