CLEANING VS. SANITIZING
This guide will address both the cleaning and the sanitizing
of the unit.
Clean the unit to remove dried food and spills, to prevent
build-up of grime, and to maintain the natural luster
stainless steel surfaces.
Sanitize the unit when exposed to raw meat juice or
human germs such as from a sneeze or being touched by
someone who is ill. Sanitizing the unit can also be part of
regular cleaning routine.
Stainless Surfaces
Stainless door panels, handles and frames 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 specically intended for
stainless steel on stainless steel surfaces (this
includes glass, tile, and counter cleaners).

quickly with Bon-Ami
®
or Barkeepers Friend Cleanser
®
and
a nonabrasive cloth. Always clean with the grain. Always
nish 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.
CLEAN INTERIOR COMPONENTS
Use warm or hot water with dish soap to clean all removed
components and interior surfaces. You may use a vinegar and
water solution in place of soap. Proceed to sanitizing.
Note: Cleaning soaps and vinegar solutions are not
sanitizers.

of the unit’s environment. Hard surfaces such as cabinets,
wood, vinyl or tiled floors and paneled walls have a
tendency to reflect normal appliance operating noises.
Listed below are common refrigeration components with a
brief description of the normal operating sounds they
make. NOTE: Your product may not contain all the
components listed.
• Compressor: The compressor makes a hum or pulsing
sound that may be heard when it operates.

SPECIFIC ERRORS AND ISSUES
Never attempt to repair or perform maintenance
on the unit until the main electrical power has
been disconnected from the unit.
The advanced diagnostic capabilities of the electronic
controls utilized on the 1, 3, and 5 Class units allow for
easy and thorough troubleshooting.
Navigation of the control is the key and is explained in
the CONTROL OPERATION section of the manual, along
with control button layout, control function descriptions,
a service mode menu and service menu selection
explanations.
Verication of temperature and thermistor performance can
be identied by directly viewing thermistor readings in the
service mode.
Component failure issues can be identied through
service mode menu #20, “Component Testing.” Individual
components can be switched on and o to check for both
proper function of a specic component and also delivery of
supply voltage to the components through the relays and
DC outputs located on the relay/power board.
Included in this section are some diagnostic tips; if
additional help is required, please contact the U-Line
Corp., “Customer Care Facility” at +1.414.354.0300 for
assistance.
NORMAL OPERATING SOUNDS
All models incorporate rigid foam insulated cabinets to
provide high thermal eciency and maximum sound
reduction for its internal working components. Despite
this technology, your model may make sounds that are
unfamiliar.
Normal operating sounds may be more noticeable because
of the unit’s environment. Hard surfaces such as cabinets,
wood, vinyl or tiled oors and paneled walls have a
tendency to reect normal appliance operating noises.
Listed below are common refrigeration components with a
brief description of the normal sounds they make. NOTE:
Your product may not contain all the components listed.
• Compressor: The compressor makes a hum or pulsing
sound that may be heard when it operates.
• Evaporator: Refrigerant owing through an evaporator
may sound like boiling liquid.
• Condenser Fan: Air moving through a condenser may
be heard.
• Water Valve: Running water and clicking as valve
opens and closes.
• Ice Dropping: Ice falling into the bin makes a dull thud
sound. The sound decreases as the bin lls with ice.
• Solenoid Valves: An occasional clicking sound may be
heard as solenoid valves are operated.

Relay & DC Outputs
One of the primary functions of the main control is to
operate the multiple relay and DC outputs during each
cycle. Verify proper operation of these relays using the
following procedure.
1. Enter “Relay Toggle” through the service menu.
Frequently toggling the compressor relay could
force the compressor into overload. The
compressor will automatically deactivate during
an overload and will remain deactivated until the
overload switch cools. This could take some
time. It is important to allow the compressor at
least 5 minutes o time between relay cycles.
2. Toggle the relay (refer to Control Operation for a
complete list of relays). Its related component should
activate / deactivate with the switching of the relay; if
it does not, test component.
Other Suspected Main Control Faults
If other components have been ruled out as being faulty,
but the unit continues to have operating issues, it is most
likely due to a conguration error. Some conguration
errors can be cleared by restoring the unit to its factory
default setting. Factory defaults may be restored through
the service menu. If that does not work, check that the
board is programmed to the correct model in the service
menu.
CAUTION
!
Precautions must be taken while working with
live electrical equipment. Be sure to follow
proper safety procedures while performing tests
on live systems.

Thermistor 1
SAFETY • INSTALLATION & INTEGRATION • OPERATING INSTRUCTIONS • MAINTENANCE • SERVICE
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
verified. 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.
1000 Series Self Preservation Mode:
The unit will cycle on for 10 minutes then off for 40
minutes.
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.

CONVECTION COOLING
This unit is equipped with an advanced convection cooling
system. Convection cooling stabilizes cabinet
temperature, cools product faster and increases energy
efficiency.
Evaporator Fan
The evaporator fan is responsible for circulating warm air
from the refrigeration zone, past the evaporator and back
into the refrigerated zone.
The evaporator fan is factory set to have a 1 minute delay
at the beginning of a cooling cycle. This delay gives the
evaporator time to cool properly before warm air is passed
over it. The fan will continue to run for an additional 2
minutes at the end of a cooling cycle.
Evaporator fan operation is also determined by door
switch state. If the door switch circuit opens, the fan will
stop. When the door switch circuit is closed the fan will
either continue running with the cooling cycle, or if not
currently cooling, the fan will run for 1 minute to circulate
air and clear any condensation that may have appeared
on glass doors and shelves.
Note: If the unit is set to sabbath mode, the evaporator
fan will no longer respond to the state of the door switch.
In order to operate efficiently, the evaporator fan blade
and vents should be unobstructed and free of any dust
buildup.
Evaporator Fan Replacement
Should the evaporator fan need to be replaced follow the
steps below.
1. Remove any product from the unit.
2. Uninstall unit.
3. Disconnect power to the unit.
4. Remove back panel from unit.
5. Disconnect fan electrical connection
6. Remove insulating foam from refrigerant line pass-
through hole as needed to gain clearance for fan plug.
