  1.  Remove the upper front cover.

  2.  Remove splash panel and lower drain pan protector.

  3.  Turn compressor switch on electrical box of 

icemaker to OFF position.

  4.  Remove water reservoir cover and close water 

supply valve.

  5.  Drain water from reservoir by releasing evaporator 

drain tube from fl oat reservoir bracket, removing 
plug from drain tube and releasing (unclamping) 
pinch valve (if equipped).

  6.  Following manufacturer’s instructions, prepare one 

gallon (3.8L) cleaning solution A or equivalent. 
Solution temperature must be at least 120 F (49 C).

 

 

WARNING:

 Most ice machine cleaners contain 

citric or phosphoric acid that can cause skin 
irritation. Read caution label on product and follow 
instructions carefully.

  7.  Plug drain hose, replace drain line in reservoir 

bracket and pour part of cleaning solution into 
reservoir, fi lling it almost to overfl owing.

  8.  Remove stainless steel compression nozzle and 

drain lines and submerge in a cup of cleaning 
solution while cleaning rest of system. 

CAUTION: 

To avoid potential pitting, do not soak 

parts in SafeCLEAN for more than 45 minutes.

  9.  Restore power to icemaker (gearmotor will run; 

compressor and fan will not).

 10.  After 15 minutes, turn power OFF; 

drain solution from reservoir and evaporator.

  11.  Fill reservoir almost to overfl owing with clean, 

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

 12.  Following manufacturer’s instructions, prepare 

1 gallon (3.8L) sanitizing solution B. Solution 
temperature must be at least 120 F (49 C).

 13.  Rinse compression nozzle in clean water and 

submerge in a cup of sanitizing solution while 
following steps 14-19.

 14.  Connect ice transport tube directly onto evaporator 

outlet port without compression nozzle.

 

 

Note:

 If bin will not be cleaned at this time, place a 

large pan in bin storage area to catch ice or connect 
a separate ice transport tube to evaporator and 
divert ice into separate container.

 15.  Fill reservoir almost to overfl owing with sanitizing 

solution.

 16.  Restore power to icemaker (gearmotor will run; 

compressor and fan will not).

  17.  After 10 minutes, turn compressor switch to ON 

position.

 18.  As unit starts to make ice, continue to pour 

sanitizing solution into reservoir, maintaining level 
just below reservoir overfl ow.

 19.  Continue to make ice with sanitizing solution for 

20 minutes.

Icemaker cleaning & sanitizing

Periodic cleaning of Follett’s icemaker 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

Quarterly air fi lter cleaning

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

of unit.

  2.  Slide panel toward back of dispenser and lift.

  3.  Remove the air fi lter located under the louver.

  4.  Clean with soap and water.

  5.  Rinse, and replace when completely dry.

Semi-annual icemaker cleaning & sanitizing

Note:

 If icemaker and dispenser are cleaned and 

sanitized at the same time, icemaker should be cleaned 
and sanitized fi rst.

Cleaning solution

Solution A:

 

Ice machine cleaner: 

Prepare one gallon 

(3.8L) of Follett SafeCLEAN™ Ice Machine cleaner (one 
7 oz packet) or equivalent. Solution temperature must be 
at least 120 F (49 C).

Warning:

 Most ice machine cleaners contain citric or 

phosphoric acid that can cause skin irritation. Read 
caution label on product and follow instructions carefully.

Sanitizing solution

Solution B:

 Combine 1 oz. (30 ml) of bleach with 2 

gal. (8 L) of hot water (at least 120 F (49 C) to form 
a 200 ppm solution of 5.25% sodium hypochlorite, or 
equivalent.

Note:

 Before cleaning SensorSAFE units, deactivate 

dispenser by depressing and releasing clean switch 
located on left side of unit under top front cover. When 
cleaning is complete, reactivate by depressing and 
releasing clean switch a second time. Dispenser will 
automatically reactivate after two minutes.
