8. Oil the fan motor if the motor has an oil fitting.
Cleaning and Sanitizing
Harvest problems may occur if the following procedures are not performed every 6 months.
1. Remove the ice machine front panel.
2. Make sure that all the ice is off of the evaporator. If ice is being made, wait for cycle completion,
then turn the machine “OFF” at the selector switch.
3. Remove or melt all ice in the storage bin.
4. Add recommended amount of approved ice machine cleaner to the water trough according to
label instructions on the container.
5. Initiate the clean cycle at the controller board switch by turning on the machine and activating the
switch marked as “CLEAN”. Note: This must be done within 3 minutes of turning the machine
“ON”. Allow the cleaner to circulate for approximately 15 minutes to remove mineral deposits.
6. After 15 minutes (or 30 minutes automatically), stop the process and drain the sump. Refill with
clean water run another 5 minutes and drain again. Fill the trough with fresh incoming water.
7. Terminate the wash cycle at the switch by placing the switch in the “OFF” position. Remove the
splash curtain (if available) and inspect the evaporator and water spillway (the plastic top of the
evaporator) to assure all mineral residue has been removed.
8. If necessary, wipe the evaporator, spillway and other water transport surfaces with a clean soft
cloth to remove any remaining residue. If necessary, remove the water distribution tube,
disassemble and clean with a bottlebrush. Reassemble all components and repeat steps 4 through 7
as required to remove residue.
9. Turn OFF ice machine water supply and clean the water trough thoroughly to remove all scale or
slime buildup. If necessary, remove the water trough to reach all splash areas and float.
10. Prepare 1½ to 2 gallons (5.7 to 7.5 liters) of approved (EPA/FDA) sodium hypochloride food
equipment sanitizer to form a solution with 100 to 200 ppm free chlorine yield.
11. Add enough sanitizing solution to fill the water trough to overflowing and activate the switch to
the “CLEAN” position and allow circulation to occur for 10 minutes and inspect all disassembled
fittings for leaks. During this time, wipe down all other ice machine splash areas, plus the interior
surfaces of the bin, deflector and door with the remaining sanitizing solution. Inspect to insure that
all functional parts, fasteners, thermostat bulbs (if used), etc. are in place.
12. After 3 minutes, stop the process and drain the sump. Refill with clean water run another 5
minutes and drain again. Fill the trough with fresh incoming water.
13. Place the switch to the “ON” position and replace or close the panel. Discard the first two ice
harvests.
How the Ice Maker Works
Refer to the Operation section of the User’s Manual (pages 12 to 14) for a clear description of how
the ice maker makes ice and uses water.
There are 3 systems: the Cooling System, the Water System and the Electrical System.
