Condenser (air-cooled ice machine only)
1. Use a vacuum cleaner or stiff brush to carefully clean condenser coils of lint and debris to ensure optimal
performance.
2. When reinstalling counter panels in front of RIDE model ice machines, be sure that ventilation louvers line
up with condenser air duct.
Semi-Annually (more often if conditions dictate)
§ A cleaning/descaling and sanitizing procedure should always include both the ice machine and dispenser; ice
machine should be cleaned and sanitized fi rst, followed by the dispenser.
§ Icemaking system can be cleaned/descaled in place.
To ensure that your ice machine and dispenser are cleaned/descaled and sanitized properly, proceed as follows:
1. Clean/descale the ice machine
2. Sanitize the ice machine
3. Clean/descale the dispenser
4. Sanitize the dispenser
§ Wear rubber gloves and safety goggles (or face shield) when handling cleaner or sanitizer mixtures.
§ Use only Follett approved cleaners.
§ It is a violation of Federal law to use Solution A or Solution B in a manner inconsistent with their labeling.
§ Do not use solvents, abrasive cleaners, metal scrapers or sharp objects to clean any part of the dispenser.
Solution A: Following manufacturer's instructions, mix cleaning solution of 1 gal. (3.8 L) 120 F (49 C) water and 7 oz.
(198 g) (one 7 oz. packet) of Follett SafeCLEAN™ ice machine cleaner/descaler (P/N 00132001).
Solution B: Following manufacturer's instructions, mix a sanitizing solution of 1 gal. (3.8 L) 120 F (49 C) water and
1.6 oz. (48 ml) Nu-Calgon IMS-II Sanitizer (P/N 00979674).
Clean/descale ice machine
1. If ice machine was running recently, ensure that the evaporator is completely free of ice before proceeding.
2. Disconnect power to ice machine.
3. Remove any ice machine panels required to gain access to water reservoir and electrical control box.
4. Turn compressor switch on electrical box of ice machine to OFF position.
5. Remove water reservoir cover and close water supply valve (or block up reservoir fl oat).
6. Drain water from reservoir by releasing evaporator drain tube from fl oat reservoir bracket, removing plug from
drain tube and releasing (unclamping) pinch clamp (if equipped).
7. Plug drain hose, replace drain line in reservoir bracket and pour part of Solution A into reservoir, fi lling it almost
to overfl owing.
8. Remove stainless steel ice compression nozzle and drain lines and submerge in a cup of Solution A while
cleaning/descaling rest of system. (Flake ice machines have no ice compression nozzle and drain lines.)
CAUTION: To avoid potential pitting, do not soak parts in Solution A for more than 45 minutes.
9. Restore power to ice machine (gearmotor will run; compressor and fan will not).
10. Inspect evaporator drain pan and drain line and remove any accumulated scale build up.
11. After 15 minutes, turn power OFF; drain solution from reservoir and evaporator.
12. Fill reservoir almost to overfl owing with clean water to rinse. Drain. Repeat two more times.
13. Rinse ice compression nozzle and drain lines in clean water.
Sanitize ice machine
14. Submerge ice compression nozzle and drain lines in a cup of Solution B while following steps 15-21.
15. Connect ice transport tube directly onto evaporator outlet port without ice compression nozzle.
16. Fill reservoir almost to overfl owing with Solution B.
17. Restore power to ice machine (gearmotor will run; compressor and fan will not).
18. After 10 minutes, turn compressor switch to ON position.
19. As unit starts to make ice, continue to pour Solution B into reservoir, maintaining level just below reservoir
overfl ow.
