and will void the warranty.
Never use an extension cord to connect power to
the unit.
Always keep your working area dry.
NOTICE
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.

Cutout Dimensions
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.
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.

General Installation
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
legs.
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.
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.

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.
NOTICE
The integrated panel aligns with the surrounding
cabinetry and, due to differences in cabinetry,
may not align perfectly with the drawer.
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).
Integrated Panel Preparation
1. Cut the main panel to the dimensions below. For
details, see the drawings on the next page.
2. Create the top design for the handleless feature and
the 1/8" notch for the insert(s) indicated on the Top
Detail drawing.
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.
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.
NOTICE
If finishing panel or wooden insert, all sides
must be finished to prevent warping.
5. Attach the insert to the panel. Wood glue or equivalent
adhesive should be used to attach insert to panel.

SIDE-TO-SIDE ADJUSTMENT
The drawer will need a Side-
to-Side Adjustment if, when
viewed from the top, the
drawer front is not square with
the sides of the cabinet. This
is caused by one of the slides

Minor Adjustment:
Note: The mounting holes on
the slide are slightly larger
than the screws’ diameter.
1. Loosen the slide’s
mounting screws.
2. Push the slide backward.
3. Retighten the screws.
Severe Adjustment:
Note: The slides have extra
mounting holes that may be
used.

Cleaning
EXTERIOR 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.
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.
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
instruments can puncture the inner lining or
damage the cooling unit. DO NOT use any type of
heater to defrost. Using a heater to speed up
defrosting can cause personal injury and
damage to the inner lining.

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 +1.800.779.2547.
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.
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.
• 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.

CAUTION
!
Never attempt to repair or perform maintenance
on the unit until the main electrical power has
been disconnected from the unit.
SPECIFIC ERRORS AND ISSUES
The technically advanced diagnostic capabilities of the
electronic controls utilized on the 1200 and 2200 series
units allows 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.
Verification of temperature and thermistor performance
can be identified by directly viewing thermistor readings in
the service mode.
Component failure issues can be identified through service
mode menu #19, “Component Testing.” 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 are some diagnostic tips and of
course, if additional help is required please contact the
U-Line Corp, “Customer Care Facility” at +1.800.779.2547
for assistance.
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.
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.
• 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.
Solenoid Valves: An occasional clicking sound may be
heard as solenoid valves are operated.

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.
NOTICE
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, 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 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.

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.

VI EW I NG ACTUAL TEM PERATURE
In viewing temperature in these modes any offsets are
taken into account. This means that if you place a therm-
istor in a known temperature, let ’s say ice water, it may
not read the 32° F that you would assume. If the control
offset was preset at - 3° F while you placed the thermistor
in an icebath, the actual thermistor reading when viewing
actual temperature would read 35° F. In the unit this would
cause the cabinet to push itself 3° cooler. To view pure
thermistor readings you must go into the service menu
and choose the correct option.
To view the thermistor temperature, push and release the
up and down keys. The display will show the corrected
refrigerator temperature.
SH OW ROOM MOD E
This mode is designed to show units in a display environ-
ment. When in this mode the only functions will be the

and the power key for 5 seconds. The display will flash
once and beep and the degree symbol will begin to flash.
When the degree symbol is flashing the unit will allow the
use of the control for demonstrations. The unit can be left
in this mode indefinitely.

changing a setting, you must press the LIGHT key again
to retain the changed setting. To exit the service mode
scroll to option “0” and press the LIGHT key. After five

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.
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.
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 three 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 three (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.
2000 Series Self Preservation Mode:
The unit will cycle on for 10 minutes then off for 40
minutes.
3000 Series Self Preservation Mode:
Cycle times determined by zone - see chart. The error will
be displayed on the main display, “Self Test” and logged in
“All Errors.”
Self Preservation Mode Data Table - 3000 Series
Evaporator Thermistors
If an 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.
