Cleaning
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 of Follett’s 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 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.

**Recommended cleaning intervals***

• Ice machine must be cleaned prior to start-up.
  Weekly
  The exterior may be cleaned with a stainless cleaner such as 3M™ Stainless Steel Cleaner & Polish or equivalent.
  Monthly
  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 procedure should always include both the ice machine and bin/dispenser.
• Icemaking system can be cleaned in place.

Cleaning Tool Checklist

• (1) 1.5 gallon (or larger) plastic bucket
• (2) clean cloths
• Sanitary gloves
• Safety glasses
• Safe CLEAN™ Plus ice machine cleaner
• (2) Sani Sponge™ (PN 00131524 – single sponge)

CAUTION!

• Wear rubber gloves and safety goggles (or face shield) when handling Safe CLEAN Plus solution.
• Use only Follett approved cleaners.
• Do not use solvents, abrasive cleaners, metal scrapers or sharp objects to clean any part of the dispenser.

Safe CLEAN Plus Solution: Follow the directions on the Safe CLEAN Plus packaging to mix 1 gal. (3.8 L) of Follett Safe CLEAN Plus solution. Use 100 F (38 C) water.

Cleaning 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 Procedure again.

2. Remove front or top cover.

3. Disconnect bin signal cable from ice machine electrical box.

4. Press CLEAN switch. The MAINTENANCE light will turn on and the machine will drain. Wait for the LOW WATER light to turn on.

5. Remove lid from cleaning cup and fill (about 1 quart) until Safe CLEAN Plus solution completely fills the reservoir. Place lid back on cup.

6. CLEANER FULL light will turn on and machine will start cleaning cycle then rinse three times; this process takes approximately 15 minutes.

7. When machine is finished cleaning, the MAINTENANCE light will turn off.

8. Remove top bearing 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.

9. Soak one Sani Sponge in remaining Safe CLEAN Plus solution.

10. Insert the sponge soaked in Sophoclean Plus solution into nozzle then insert a dry sponge into the nozzle.

11. Replace nozzle onto evaporator and tighten screw. Ensure drain is connected to reservoir and vent tubes are connected to evaporator drain pan. Replace top bearing insulation.

12. Reconnect bin signal cable. Wait for ice to push sponges through transport tube.

13. Collect sponges from ice storage bin.

14. Replace front or top cover.

15. After 10 minutes, dispense all ice and discard.

16. Clean the dispenser/bin.

Exterior Cabinet
Clean stainless steel panels with stainless steel cleaner.

Electrical system

ATTENTION!
To prevent circuit breaker overload, wait 15 minutes before restarting this unit. This allows the compressor to equalize and the evaporator to thaw.
Normal control board operation
The PC board indicator lights provide all the information necessary to determine the machine’s status. Green indicator lights generally represent “go” or normal operation; Yellow indicators represent normal off conditions; Red indicators generally represent alarm conditions, some of which will lock the machine off.
A flashing green light labeled POWER indicates power to the machine. All other normal operation status indicators are covered as follows:

fills with ice, the LOW BIN light goes out momentarily and the refrigeration and auger drive systems immediately shut down. ( Note: The fan motor will continue to run for 10 minutes to cool condenser) The TIME DELAY light comes on, initiating the time delay period. When the time delay expires, the machine will restart provided that the LOW BIN light is on.

DIP Switch Settings

• Flush can be enabled on Symphony CT and FB models. Flush should be disabled on Symphony CI units due to risk of internal leak if drain line is blocked. All Symphony Plus models should be set to Flush enabled.
