Installing wall mount dispensers

WARNING

• Wall mount dispensers are intended to be mounted above a
sink, eliminating the need for a drain pan.

• Before beginning installation verify that the sink size and
location meet the requirements shown in Fig. 7.

• If requirements are not met, a drain pan must be used to
prevent ice and water from falling on counter or  oor.

• FAILURE TO TAKE THESE PRECAUTIONS COULD RESULT IN
SLIPS AND FALLS ON WET FLOORS

• It is a violation of Federal law to use these solutions in a
manner inconsistent with their labeling

• Read and understand all packaging instructions before use

• Do not use solvents, abrasive cleaners, metal scrapers or
sharp objects to clean any part of the dispenser

Quarterly air  lter cleaning

1. Remove screw at top of louvered panel on left side

120 F (49 C) water, and drain. Repeat three times.

24. Open water supply valve and replace reservoir
cover. Restore power to icemaker and ensure
compressor switch is in ON position. Make ice for
at least 15 minutes to  ush any remaining solution
from system. Discard this and all ice made during
sanitizing.

25. Inspect evaporator drain pan and drain line and
remove any accumulated scale build up.

26. Replace any panels removed prior to cleaning.

Start-up following cleaning

1. Clean and sanitize ice storage area of dispenser in
accordance with instructions before making ice.

2. Turn icemaker on and begin to make ice. Icemaker
should start immediately with power and bin signal
supplied.

3. After approximately 30 minutes, test dispenser for
proper dispensing.

Dispenser cleaning & sanitizing

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

WARNING

• To reduce risk of electrical shock disconnect
power before servicing

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

CAUTION

• Use only Follett approved cleaners (see procedure below).

• It is a violation of Federal law to use these solutions in a
manner inconsistent with their labeling

• Read and understand all packaging instructions before use

• Do not use solvents, abrasive cleaners, metal scrapers or
sharp objects to clean any part of the dispenser

Cleaning solution

Solution A: Prepare cleaning solution (200 ppm of

available chlorine content) of Ecolab Mikro-chlor Cleaner
or equal chlorinated detergent. Solution temperature

Icemaker operation

Follett’s icemaker consists of four distinct functional systems:

• Refrigeration system

• Water system

• Harvesting system

• Electrical control system

These four systems work together to accomplish the production and harvesting of ice. A problem in any one of these
systems will result in improper operation of the entire ice production cycle. When troubleshooting the icemaker, it is
important to analyze the entire system operation to determine which system is not functioning properly, then pinpoint
the component within that system that is malfunctioning. Determine what corrective action must be taken before
making any adjustments or replacing any components.

The icemaking process

The Follett icemaker uses a stainless steel jacketed evaporator and operates on a continuous freezing cycle.
Water is supplied to the evaporator from the water reservoir where the water level is controlled by a  oat valve.
This valve also shuts off the water supply when the icemaker is not running.

When the icemaker is running, a layer of ice
forms on the interior surface of the evaporator.
This ice is continuously removed by a slowly
rotating (12 RPM) auger.

Ice harvest system diagram

The auger carries the ice upward into the cavity
formed by the top bearing housing and the
compression loop, where it is compressed to
remove excess water.

When the ice reaches the desired hardness it
rotates within the cavity and is forced through
a discharge port and compression nozzle and
into the ice transport tube. The discharge tube
and compression nozzle are slightly restricted
to further compress the ice and produce the
desired hardness. As the formation of ice
continues, ice in the transport tube is pushed
through the tube to the storage compartment in
the ice dispenser.

A solid state control board, located in the
electrical box of the icemaker, controls the
normal operation of the icemaker and monitors
gearmotor torque. This control board will shut
down the icemaker should an over-torque
condition occur. It is very important that
you familiarize yourself with the operational
sequences detailed in this manual before
attempting to service the icemaker.
