Scotsman Self Contained Cuber CU1526 User manual

Cleaning, Sanitation and Maintenance
This ice system requires three types of maintenance:
•Remove the build up of mineral scale from the ice machine’s water system and sensors.
•Sanitize the ice machine’s water system and the ice storage bin.
•Clean or replace the air filter and clean the air cooled condenser (air cooled models only).
It is the User’s responsibility to keep the ice machine and ice storage bin in a sanitary condition. Without
human intervention, sanitation will not be maintained. Ice machines also require occasional cleaning of
their water systems with a specifically designed chemical. This chemical dissolves mineral build up that
forms during the ice making process.
Sanitize the ice storage bin as frequently as local health codes require, and every time the ice machine
is cleaned and sanitized.
The ice machine’s water system should be cleaned and sanitized a minimum of twice per year.
1. Remove the left front louvered panel.
2. Remove the top panel.
3. If the machine is operating, push and release
the Harvest button. When the machine
completes the Harvest cycle it will stop. If the
bin is full (b shows in display) push and release
the Off button.
4. Remove all ice from the storage bin
5. Push and release the Clean button. The yellow
Clean light will blink and the display will show
C. The machine will drain the reservoir and refill
it. Go onto the next step when the reservoir has
filled.
6. Pour 8 ounces of Scotsman Clear 1 ice
machine scale remover into the reservoir.
7. Allow the ice machine scale remover to
circulate in the water system for at least 10
minutes.
8. Push and release the Clean button again. The
yellow Clean light will be on continuously and
the machine will drain and refill the reservoir
repeatedly to purge out the ice machine scale
remover and residue.
9. Allow the drain and refill process to continue for
at least 20 minutes.
10. Push and release the Off button. The clean
cycle will stop and the display will show O.
Note: If unit has not been de-scaled for an
extended period of time and significant mineral
scale remains, repeat steps 5-10.
11. Mix a cleaning solution of 1 oz of ice machine
scale remover to 12 ounces of water.
12. Locate curtain, push in on edge of curtain by
pivot pin to release it. Pull curtain out of
machine.
13. Remove water distributor from ice machine.
Inspect distributor for restricted orifice holes.
Be sure all holes are fully open.

Ice machine scale remover
contains acids. Acids can
cause burns.
If concentrated cleaner
comes in contact with skin,
flush with water. If swallowed,
do NOT induce vomiting.
Give large amounts of water
or milk. Call Physician
immediately. Keep out of the
reach of children.

14. Locate ice thickness sensor. Squeeze
mounting legs together to release sensor.
Wash the metal surfaces of the sensor and the
adjustment screw with ice machine scale
remover solution. Also wash the water
distributor and curtain with the ice machine
cleaner solution.
15. Locate water sensor. Squeeze catches
together and pull up to remove sensor. Wash
metal surfaces of sensor with ice machine
scale remover solution.
16. Mix a solution of sanitizer.
Note: A possible sanitizing solution may be made
by mixing 1 ounce of liquid household bleach with 2
gallons of warm (95-115oF.) potable water.
17. Thoroughly wash all surfaces of the ice
thickness sensor, water level sensor, curtain
inside of the top panel and the water distributor
with the sanitizer solution.
18. Wash all interior surfaces of the freezing
compartment, including storage bin liner with
the sanitizer solution.
19. Return water level sensor, ice thickness
sensor, water distributor and curtain to their
normal positions.
20. Push and hold the clean button to drain the
reservoir. Push and release the clean button
again and when the purge valve indicator light
goes out, immediately pour the remaining
cleaning solution into the reservoir.
21. Circulate the sanitizer solution for 10 minutes,
then push and release the Clean button.
22. Allow the water system to be flushed of
sanitizer for at least 20 minutes, then push and
release the Off button.
23. Push and release the On button to resume ice
making.
24. Return the top panel and front louvered panel
to their normal position and secure with the
original fasteners.
Air cooled condenser filter used on the
CU1526 and CU2026 only
1. Remove left front grill .
2. Wash the dust and grease off the filter.
3. Return it to its original position.
Air cooled condenser
If the machine does not have a air filter the air
cooled condenser fins will need to be cleaned. The
fins are located behind the fan blades. The
services of a refrigeration technician is
recommended to properly clean the condenser.
Exterior Panels
Fingerprints, dust and grease can build up on the
panels and will require occasional cleaning.
Water filters
If the machine has been connected to water filters,
check the cartridges for the date they were
replaced or for the pressure on the gauge. Change
cartridges if they’ve been installed more than 6
months or if the pressure drops too much when the
ice machine fills with water.
