WARNING
!
SHOCK HAZARD — Electrical Grounding
Required. Never attempt to repair or perform
maintenance on the unit until the electricity has
been disconnected.
Never remove the round grounding prong from
the plug and never use a two-prong grounding
adapter.
Altering, cutting or removing power cord,
removing power plug, or direct wiring can cause
serious injury, fire, loss of property and/or life,
and will void the warranty.
Never use an extension cord to connect power to
the unit.
Always keep your working area dry.
Electrical installation must observe all state and
local codes. This unit requires connection to a
grounded (three-prong), polarized receptacle
that has been placed by a qualified electrician.
The unit requires a grounded and polarized 115 VAC,
60 Hz, 15A power supply (normal household current). An
individual, properly grounded branch circuit or circuit
breaker is recommended. A GFCI (ground fault circuit
interrupter) is usually not required for fixed location
appliances and is not recommended for your unit because
it could be prone to nuisance tripping. However, be sure
to consult your local codes.
See CUTOUT DIMENSIONS for recommended receptacle
location.

PREPARE SITE
Your U-Line product has been designed exclusively for a
built-in installation. When built-in, your unit does not
require additional air space for top, sides, or rear.
However, the front grille must NOT be obstructed.
The product is designed and manufactured for seamless
integration in the specified cutout opening shown, which
requires precise measurements. The opening must be
square and plumb front to back. Although not required,
you may choose to increase the overall cutout width for
ease of installation.
The Modular 3000 Series units are engineered with a
variety of adjustment features to help ensure a seamless
installation. Adjustable doors, leveling legs and grille will
assist in fine tuning the installation.
CUTOUT DIMENSIONS
Metric measurements rounded and optimized.
All 3000 Series models fully integrate into overlay/face
frame, inset or European/frameless cabinet styles and
install seamlessly into standard 24" (610 mm) depth
cabinet base.

Cutout width for a side-by-side installation is the total of
the widths listed under Cutout Dimensions in each unit’s
Installation Guide. Each door can be opened individually
(one at a time) without interference.
Hinge-by-Hinge Installation (Mullion)
When installing two units hinge-by-hinge, 13/16" (22 mm)
is required for integrated models. Additional space may be
needed for any knobs, pulls or handles installed.
Stainless steel models which include the standard stainless
handle will require 4-9/16" (116 mm) to allow both doors
to open to 90° at the same time.
However, to ensure unobstructed door swing (opening
both doors at the same time), 1/4" (6.4 mm) of space
needs to be maintained between the units.

1. Use a level to confirm
the unit is level. Level
should be placed along
top edge and side edge
as shown.
2. If the unit is not level, remove grille and adjust legs as
necessary. Use included tool to adjust the height of the
rear legs.
INSTALLATION
1. Plug in the power/electrical cord.
2. Gently push the unit into position. Be careful not to
entangle the cord.
3. Re-check the leveling, from front to back and side to
side. Make any necessary adjustments. The unit’s top
surface should be approximately 1/8" (3 mm) below
the countertop.
4. Install the anti-tip bracket.
5. Remove the interior packing material and wipe out the
inside of the unit with a clean, water-dampened cloth.
3. Confirm the unit is level after each adjustment and
repeat the previous steps until the unit is level.
INSTALLATION TIP
If the room floor is higher than the floor in the cutout
opening, adjust the rear legs to achieve a total unit rear
height of 1/8" (3 mm) less than the opening’s rear height.
Shorten the unit height in the front by adjusting the front
legs. This allows the unit to be gently tipped into the
opening. Adjust the front legs to level the unit after it is
correctly positioned in the opening.

HANDLELESS INTEGRATED DRAWER PANELS
The following procedure is designed to provide a finished,
handleless solid panel for a 24" (600 mm) drawer that
seamlessly integrates with its surrounding cabinetry.
Prepare two panels for your drawer unit.
NOTE: Many cabinet manufacturers provide a ready
solution for a handleless, integrated design that can be
easily applied to your U-Line 3000 Series model. Consult
your cabinet manufacturer for applicable design and
installation details. The cabinet manufacturer’s solution to
this design and integration detail will often result in an
integrated panel solution wherein the size of the panel
may result in a height dimension taller than what we
specify. This can be achieved provided the additional
height is positioned above the appliance drawer.
The integrated panel aligns with the surrounding
cabinetry and, due to differences in cabinetry,
may not align perfectly with the drawer.
3. Prepare the insert(s) that will back up the handleless
design. Wooden Insert – Cut 1/8" thick wooden
insert(s) to the dimensions below.
Wooden insert width Wooden insert height
23-1/2" (595 mm) 3-1/2" (89 mm)
4. Optional: Stain or finish panel and wooden insert to
desired stain or color. Be sure to closely follow the
instructions provided by the manufacturer.
The appliance will need up to 34-1/2" (876 mm)
to the underside of the counter to leave room for
leveling adjustments.
Each drawer panel with insert must not weigh
more than 20 lbs (10 kg).

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
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.

Integrated Models
To clean integrated panels, use household cleaner per the
cabinet manufacturer’s recommendation.
INTERIOR CLEANING
Disconnect power to the unit.
Clean the interior and all removed components using a
mild nonabrasive detergent and warm water solution
applied with a soft sponge or non-abrasive cloth.
Rinse the interior using a soft sponge and clean water.
Do not use any solvent-based or abrasive
cleaners. These types of cleaners may transfer taste to
the interior products and damage or discolor the lining.
DEFROSTING
Under normal conditions this unit does not require manual
defrosting. Minor frost on the rear wall or visible through
the evaporator plate vents is normal and will melt during
each off cycle.
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
and a nonabrasive cloth. Always clean with the grain.
Always finish with Claire
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.

If there is excessive build-up of 1/4" (6 mm) or more,
manually defrost the unit.
Ensure the door is closing and sealing properly.
High ambient temperature and excessive humidity can
also produce frost.
CAUTION
!
DO NOT use an ice pick or other sharp
instrument to help speed up defrosting. These

Troubleshooting
BEFORE CALLING FOR SERVICE
If you think your U-Line product is malfunctioning, read
the CONTROL OPERATION section to clearly understand
the function of the control.
If the problem persists, read the NORMAL OPERATING
SOUNDS and TROUBLESHOOTING GUIDE sections below
to help you quickly identify common problems and
possible causes and remedies. Most often, this will resolve
the problem without the need to call for service.
IF SERVICE IS REQUIRED
If you do not understand a troubleshooting remedy, or
your product needs service, contact U-Line Corporation
directly at +1.414.354.0300
When you call, you will need your product Model and
Serial Numbers. This information appears on the Model
and Serial number plate located on the upper right or rear
wall of the interior of your product.
NORMAL OPERATING SOUNDS
All models incorporate rigid foam insulated cabinets to
provide high thermal efficiency 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 floors and paneled walls have a
tendency to reflect normal appliance operating noises.
• Evaporator: Refrigerant flowing through an evaporator
may sound like boiling liquid.
• Condenser Fan: Air moving through a condenser may
be heard.
• Automatic Defrost Drain Pan: Water may be heard
dripping or running into the drain pan when the unit is
in the defrost cycle.

SPECIFIC ERRORS AND ISSUES
The technically advanced diagnostic capabilities of the
electronic controls utilized on the 3000 series units allows
for easy and thorough trouble shooting.
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.
Verification of temperature and thermistor performance
can be identified by directly viewing actual temperature
readings in the service mode.
Component failure issues can be identified through service
mode menu selection, “Relay Toggle” Individual
components can be switched on and off to check for both
proper function of a specific 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 is some diagnostic tips and as
always, if additional help is required please contact the
U-Line Corp, “Customer Care Facility” at +1.800.779.2547

MAIN CONTROL
The main control board is very robust and is rarely the
cause of system issues. It is important to fully diagnose
the board for any suspected failures before attempting to
remove the board for replacement or service. Follow the
guidelines below to fully test and diagnose the main
control.
Power Fault
If the unit does not (or seems to not) power on, follow the
flow chart below to help diagnose the issue. Before
beginning it is important to first verify the unit is not
simply set to sabbath mode.
Testing The Main Control
If the main control is suspected of being faulty, the
following procedure should be performed to verify main
control for functionality.
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 off time between relay cycles.
2. Toggle the relay. Its related component should
activate / deactivate with the switching of the relay. If
it does not, see “Component Testing.”
Inputs
The main control monitors a number of thermistor inputs
and switch states during operation. It would be unlikely
that an error in reading an input would be at the board
level. Always attempt to replace the faulty switch or
thermistor input with a known working sample to verify
proper board operation.
Troubleshooting - Extended 3
USER GUIDE
u-line.com
SAFETY • INSTALLATION & INTEGRATION • OPERATING INSTRUCTIONS • MAINTENANCE • SERVICE
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 configuration error. Configuration errors
can be cleared by restoring the unit to its factory default
setting. Factory defaults may be restored through 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.
CONVECTION COOLING
All 3000 series units are equipped with an advanced
convection cooling system. Convection cooling stabilizes
cabinet temperature, cools product faster and increases
energy efficiency.
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
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. Fan delay times can
be modified through the service menu.
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.

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. In an ice water
bath (32°F) resistance should measure 16.1 kilohms.

REED SWITCH
A reed switch is used to monitor door state. When the
door is closed magnetic force pulls the reed to its contact
and closes the circuit which turns the light and display off.
When the door is open the reed pulls away from the
contact and opens the circuit. If the door is left open for
longer than 5 minutes, the switch will trigger an error code
and set an audible warning.
Zone Thermistor
If the zone thermistor fails, the unit will continue to
operate in a timed limp mode which varies by model. The
unit will otherwise operate normally. The error will be
displayed in the error log.
Evaporator Thermistor
If the evaporator thermistor fails, the unit will rely on a
preset defrost time during defrost cycles. The unit will
otherwise operate normally. Evaporator thermistor errors
will be displayed in the error log.
Always assure that all thermistor connections are clean
and dry. Whenever opening a thermistor connection be
sure to apply a fresh dab of die electric grease.

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.
All 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.
Thermistor three (Zone):
Located along the right hand side wall in the bottom/right
compartment. It is used to maintain the operating
temperature within that zone.
Thermistor four (Evaporator):
Located on the evaporator in the bottom/right
compartment. It is used for defrost.
Thermistor five (Ambient):
Located in the base of the unit (secured to the
condenser). It is used to monitor the ambient temperature
within the base compartment. It is used for diagnostics.
THERMISTOR FAILURE
Zone Thermistors
If a zone thermistor(s) 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.
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 five thermistors.
Thermistor one (Zone):
Located along the right hand side wall in the top/left
compartment. It is used to maintain the operating
temperature within that zone.
Thermistor two (Evaporator):
Located on the evaporator in the top/left compartment. It
is used for defrost.

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.
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.
7. Remove the drawer from the zone with defective fan.
