Frequency: Recommended about twice a year. Units that are used heavily or are on highly mineralized water
may require more frequent cleaning.
Cleaning this machine involves adding a solution of scale remover and water to the ice machine and continuing
to add it as it makes ice. The scale remover must be diluted to the correct ratio. This is followed by sanitizing.
The ice machine must be connected to power, water and drain during this process. Recommended tools:
Rubber gloves, small scrub brush & scale remover.
1. Remove the top panel for reservoir access.
Note: If the unit must be pulled out to remove the panel and access the water reservoir, be sure that the water
supply, drain and power remain connected
2. Remove the front panel for control access.
3. Scoop out and discard all of the ice.
4. Press and hold the O󰀨 button until the machine shuts o󰀨.
5. Locate oat valve on/o󰀨 lever. Rotate to shut water supply OFF.
6. Push tab on front edge of reservoir cover and remove the cover.
Note: Adjacent wires are low voltage and are not hazardous.
7. Locate drain plug and pull the drain plug out to drain the reservoir and evaporator. When draining is
complete, return the plug to its original position.
8. Mix a solution of Clear 1 scale remover with water: 2.5 ounces of Clear 1 with 1 quart (32 oz) of warm
(900F/320C to 1100F/430C) potable water.
Note: Take care not to spill any scale remover on any nearby surface. Immediately wipe any spill with baking
soda and water.
9. Fill the reservoir with the scale remover solution. That will be about 8 ounces.
10. Unscrew (rotate CCW) and remove the ice sweep.
11. Wash the ice sweep and lower part of the breaker with the scale remover solution. Remove as much scale
as possible.
Caution: Be SURE no scale remover contacts the bearing.
12. Return the ice sweep to its original position.
13. Press and HOLD the both the On and O󰀨 buttons for 5 seconds. The Time to Clean light will blink on and
o󰀨.
The auger motor will be operating for 20 minutes, after that the compressor will start and in about 5-8 minutes
the machine will start to make ice. The Time to Clean light will now glow steady until the clean cycle is
complete.
Caution: Keep ngers away from moving parts.

14. After ice making starts, continuously add scale remover solution to the reservoir to keep it about half full.
15. When all remaining solution is used, rotate the oat valve lever to the ON position. Ice will continue to be
made.
16. After 40 minutes (20 of no ice making and 20 making ice) the ice machine and all the control panel lights
will shut o󰀨.
17. Rotate oat valve lever to O󰀨 and pull the drain plug again to drain the system, then replace it.
18. Pour a gallon of hot (95oF. – 115oF.) water into the bin to ush out the drain and melt all ice that was made
during the cleaning process. Be sure all ice is melted.
19. Mix another solution of 2.5 ounces of Clear 1 Scale Remover and 1 quart of 900F/320C to 1100F/430C
potable water and clean the bin liner of mineral scale by using the scale remover solution to scrub the scale o󰀨
of the liner.
20. Rinse the liner with hot water.
Sanitize Water System after scale removal to complete the Water System Cleaning process.
1. Create a solution of sanitizer.
2. Mix 4 oz/118ml of NuCalgon IMS and 2.5 gal/9.5L of (900F/320C to 1100F/430C ) potable water to create a
200 ppm solution.
3. Rotate the reservoir’s water shut o󰀨 valve to shut the water supply OFF. If water reservoir cover has been
placed on reservoir, remove it.
4. Pour the sanitizing solution into the reservoir until it is full to but not over the overow point (about 8 oz) and
wait 2 minutes.
5. Press the On button to turn the ice machine ON.
6. Operate the machine for at least 15 minutes, adding sanitizer to the reservoir as needed to keep it at least
half full, and then push and release the O󰀨 button to shut it OFF.
7. Remove the ice sweep.
8. Wash the reservoir cover, ice sweep, breaker and the inside of the ice chute with the sanitizer solution.
Caution: Do not allow sanitizer to contact the bearing.
9. Return the ice sweep to its normal position.
10. Return the reservoir cover to its normal position.
11. Drain the solution from the system by pulling the drain plug.
12. Return plug when drained.
13. Rinse bin liner with clean water. Be sure all ice has been melted.
14. Use sanitizer mix on all bin surface areas and areas that may contact the ice.
15. Rinse with clean water.
16. Rotate water shut o󰀨 valve to turn the water supply ON.
17. Push and release the On button to restart ice making.
18. Operate the machine for 15 minutes and then pour water onto the ice in the bin until it has all been melted.
19. Return the top and front panels to their normal positions.
The ice scoop should be washed regularly, wash it just like any other food container
