Operation
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 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.

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

Solution A – Sanitizing solution:
Prepare 1 gallon (3.8L) of 200ppm 5.25% Sodium Hypochlorite solution
(mix 1 oz household bleach to 2 gallons water) or equivalent. Solution
temperature must be at least 120 F (48.9°C).
Solution B – Ice machine solution:
Following manufacturer's instructions, prepare one 7oz packet of Follett
SafeCLEAN
™
Ice Machine Cleaner or equivalent. Solution temperature
must be at least 120 F (48.9°C).
1. Remove evaporator unit panels required to gain access to water
reservoir components (Fig. 7) and electrical control box (Fig. 8).
2. Turn compressor switch OFF (Fig. 8.3).
3. Dispense all ice from dispenser.
4. Shut OFF water valve.
5. Drain water from reservoir through float/evaporator drain line
(Fig. 7.1). Reinsert hose into hose clip (Fig. 7.3).
6. Remove water reservoir lid and fill reservoir (Fig. 7.2) with Solution B.
7. Restart icemaker and allow gearmotor to run with the compressor off
for 15 minutes.
8. While waiting 15 minutes, follow step 8a through 8c.
a)
Remove ice compression nozzles (Fig. 9.1). Soak in Solution B.
b)

up and down. Vacuum residue out.
c) Inspect all drain lines. Clean as necessary with Solution B.
9. Turn bin signal switch (Fig. 8.1) on electrical box of icemaker OFF.
10. Drain Solution B through float/evaporator drain line (Fig. 7.1). Rinse
evaporator by filling reservoir (Fig. 7.2) with potable water and draining
evaporator through float/evaporator drain line (Fig. 7.1) three times.
Reinsert hose to hose clip and plug into end of drain line (Fig. 7.1).
11. Connect ice transport tubes (Fig. 9.3) directly to evaporator outlet
ports (without ice compression nozzle) (Fig. 9.4).
Note
: If bin will not be cleaned at this time place a large pan in the
storage area to catch ice or connect a separate ice transport tube to
evaporators and divert ice into a separate container.
