Cleaning/descaling and sanitizing
Follett ice machines and dispensers, and their associated cleaning and sanitizing procedures, are designed
for use with potable water sources. The presence, or suspected presence, of infectious agents may call
for additional measures, including the replacement of components and more comprehensive disinfection
measures. Follett recommends that these cleaning and sanitizing procedures be reviewed with the appropriate
infectious agent subject matter experts to assure complete remediation.
Periodic cleaning/descaling and sanitizing of Follett’s ice and water dispenser and ice machine 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/descaling and sanitizing of
the ice machine system should be performed by your facility’s trained 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.

Cleaning/descaling procedure
Note: Check drains and drain cup to ensure they are open and flowing freely.
1. If ice machine was running recently, ensure that the evaporator is completely free of ice before
proceeding. If there is ice in the evaporator, complete steps 2-7 using only hot water to remove the ice
then begin Cleaning/Descaling Procedure again.
2. Remove front cover and turn OFF bin signal switch.
3. Dispense all ice from storage hopper and discard.
4. Remove top of machine and hopper lid.
5. Press CLEAN switch. The MAINTENANCE light will turn on and the machine will drain. Wait for the
LOW WATER light to turn on.
6. Remove lid from cleaning cup and fill (about 1 quart) until cleaning solution overflows from the ice
transport tube into the hopper. Place lid back on cup. Save remainder of cleaning solution.
7. CLEANER FULL light will turn on and machine will start cleaning cycle then rinse three times; this
process takes approximately 15 minutes.
8. While ice machine is cleaning/descaling, clean dispenser as follows:
a. Remove center thumbscrew, locking plate, two wingnuts and backing plate from front of storage hopper.
b. Remove stud assembly, baffle, wheel, and any remaining ice.
c. Remove dispense chutes from splash panel.
d. Submerse drain grille in cleaning solution and allow to soak to remove any scale buildup.
e. Wipe stud assembly, baffle, wheel, inside of storage area, dispense chutes, drain grille and drain pan
with damp cloth wrung out in cleaning solution. Thoroughly rinse all parts with damp cloth wrung out
with clean water.
Note: To avoid possible damage to motor assembly, only use a damp cloth to clean storage hopper. Do
not allow water to run through motor shaft hole in bottom of hopper.
9. When machine is finished cleaning, the MAINTENANCE light will turn off.

Sanitizing procedure
10.Press CLEAN switch. The MAINTENANCE light and LOW WATER light will turn on.
11.Fill cleaning cup with sanitizing solution until it overflows from the ice transport tube into the hopper.
Place lid back on cup. Save remainder of sanitizing solution.
12.CLEANER FULL light will turn on and machine will start sanitizing cycle then rinse three times; this
process takes approximately 15 minutes.
13.While ice machine is sanitizing, sanitize dispenser as follows:
a. Wipe inside of hopper lid, stud assembly, baffle, wheel, inside of storage area, dispense chutes, drain
grille and drain pan with damp cloth wrung out in sanitizing solution.
Note: To avoid possible damage to motor assembly, only use a damp cloth to clean storage hopper. Do
not allow water to run through motor shaft hole in bottom of hopper.
b. Reinstall dispense chutes, wheel, baffle, stud assembly, backing plate, two wing nuts, locking plate, and
thumbscrew. (See manual for correct baffle position.)
14.When machine is finished rinsing, the MAINTENANCE light will turn off. Remove top bearing
insulation and compression nozzle insulation. Loosen Phillips-head screw on nozzle connected
to evaporator. Remove nozzle from evaporator side only, leave other side of nozzle connected to
transport tube.
15.Place one Sani-Sponge in remaining sanitizing solution.
16.Insert the sponge soaked in sanitizing solution into nozzle then insert a dry sponge into the nozzle.
17.Replace nozzle onto evaporator and tighten screw. Ensure drain is connected to reservoir and vent
