Cleaning
Stainless Models
Stainless door panels and handles can discolor when
exposed to chlorine gas, pool chemicals, saltwater or
cleaners with bleach.
Keep your stainless unit looking new by cleaning with a
good quality all-in-one stainless steel cleaner and polish
monthly. For best results use Claire
®
Stainless Steel
Polish and Cleaner. Comparable products are acceptable.
Frequent cleaning will remove surface contamination that
could lead to rust. Some installations may require cleaning
weekly.
Do not clean with steel wool pads.
Do not use stainless steel cleaners or polishes on
any glass surfaces.
Clean any glass surfaces with a non-chlorine glass
cleaner.
Do not use cleaners not specifically intended for
stainless steel on stainless steel surfaces (this
includes glass, tile and counter cleaners).
If any surface discoloring or rusting appears, clean it
quickly with Bon-Ami
®
or Barkeepers Friend Cleanser
®
and a nonabrasive cloth. Always clean with the grain.
Always finish with Claire
®
Stainless Steel Polish and
Cleaner or comparable product to prevent further
problems.
Using abrasive pads such as Scotchbrite™ will
cause the graining in the stainless steel to
become blurred.
Rust not cleaned up promptly can penetrate the
surface of the stainless steel and complete
removal of the rust may not be possible.

Thermistor
Evaporator Thermistor
If the evaporator thermistor fails, the unit will rely on a
preset defrost timer during defrost cycles. The unit will
otherwise operate normally. Refer to defrost section.
Thermistor Resistance Data
Thermistors
Thermistors are used for various temperature readings.
Thermistors provide reliable temperature readings
using a resistance which varies based on surrounding
temperatures. If a faulty thermistor is suspected it may be
tested using an accurate ohmmeter.
Both thermistors in the unit are identical. If a thermistor
is suspected of being defective, the resistance can be
veried. Place the thermistor in an ice water bath, the
resistance should read 16.1k Ohms +/-5% on your meter.
Thermistor connections must be kept clean. A thermistor
connection that has become corroded can cause resistance
values from the thermistor to change as they pass through
a dirty connection to the board.
It is for that reason that we apply dielectric grease to all of
our thermistor connections. Dielectric grease will help to
keep thermistor connections clean and dry.
If you change a thermistor in the unit please re-apply
dielectric grease to the connection. If you encounter
a dirty thermistor connection, you should replace the
thermistor and the thermistor harness.
Thermistor error information can be found in the Control
Operations - Service section.
This unit has two thermistors.
Thermistor one (Zone):
Located along the right hand side wall. It is used to
maintain the operating temperature within that zone.
Thermistor two (Evaporator):
Located on the evaporator. It is used for defrost.
THERMISTOR FAILURE
Zone Thermistor
If the zone thermistor in the unit fails, the unit will
continue to cool in a backup mode (Self Preservation
Mode) to preserve the integrity of the contents. The unit
will otherwise operate normally.

ENSURING YOUR WARRANTY STAYS VALID
CLEANING AND MAINTENANCE
• Clean the Condenser Every Six Months
Failure to keep the condenser clean can result in permanent damage to the compressor.
The condenser coil is located near the compressor and usually at the bottom of the machine. In order for the condenser to perform
eciently, it must be cleaned about every six months to remove dust and debris and prevent overheating.
• Deep Clean the Ice Machine Every Six Months
Neglecting this cleaning will lead to mold or mildew buildup, cloudy ice, reduced water ow, reduced ice production,
and damage to the machine.
Use only manufacturer-approved, nickel-safe ice machine cleaner and follow all label warnings and
directions. Order ice machine cleaner online: www.u-line.com Part # 80-55667-00.
Every six months the ice machine requires a thorough cleaning to remove debris from the bin and ush out impurities that accumulates
from the water supply; clear, craft, and nugget machines are equipped with a built-in cleaning cycle.
• Clean Stainless Steel Surfaces
Your machine is built with quality stainless steel, but it can still rust when not properly maintained.
- Avoid exposure to outdoor elements such as rain, snow, sprinklers or pool splash.
- Use only a non-chlorine, non-abrasive stainless steel cleaner.
- Inspect the machine for any signs of rust. When spotted early, the rust is only on the surface and can usually be scrubbed o.
