Photo-Electric Eyes
The photo electric eyes used to "see" the ice build

off and stay off.
To clean the photo-electric eyes.
1. Remove the top panel.
2. Pull both of the photo-electric eyes out of their
rubber grommets.
3. Wash both eyes with a clean cloth dipped in
Scotsman Ice Machine Cleaner.
4. Wash the eyes off with clean water. Clean Photo-Electric
Eyes
5. Replace the eyes in the grommets
6. Replace the top panel

Water Level Sensor

machine off when the reservoir goes dry if there is
a film of mineral scale on the probe tip.
1. Remove the top panel.
2. Remove the reservoir cover.
3. Pull the water level probe up and out of the
reservoir.
4. Carefully wipe the tip of the probe with a clean
cloth. Ice machine cleaner may be needed.

6. Replace the reservoir cover and the top panel.
Water Level Probe,
Coupling
keep the tip clean.
Use the grease zerk on the side of the coupling to
add grease once per year.
That concludes normal maintenance. If the fan
motor has an oil plug, it may be oiled after 10 years
of operation.
