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.

CAUTION

Unit can NOT be installed behind a closed
cabinet door.

Side-by-Side Installation

OTHER SITE REQUIREMENTS

Side-by-Side Installation

Units must operate from separate, properly grounded

electrical receptacles placed according to each unit’s

electrical specifications requirements.

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.

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.

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.

Side-by-Side Installation 1

Anti-Tip Bracket

CAUTION

The anti-tip bracket must be installed to prevent
the unit from tipping when doors are fully
opened or excess weight is placed on the front
of the unit.

The anti-tip bracket has multiple mounting options.

Mounting will depend on your particular cabinet

configuration. Locate 3 #8x5/8" screws included with
your unit.

TOP MOUNT

For ease of installation, the anti-tip bracket is pre­installed in the top mount position.

1. Completely slide the unit into its position in the

cabinet. Be certain unit height is properly adjusted.
(See GENERAL INSTALLATION).

2. Open door completely. Make certain door clears

surrounding cabinetry.

3. Using a 3/32" (2.50 mm) drill bit, drill 3 pilot holes

5/8" (16 mm) deep into bottom of counter top. Use
the anti-tip bracket as a template.

4. Install 3 #8x5/8" screws into the plate using a #2

Phillips head screwdriver.

SIDE MOUNT

Side mount position is used when you are unable to

mount the bracket to the underside of your
countertop.

1. Remove the pre-installed anti-tip bracket from the

top mount position and align the bracket to the
hinge side of the unit as shown above.

Anti-Tip Bracket 1

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 rear 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, water­dampened cloth.

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 +1.414.354.0300

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.

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.

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.

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.

SAFETY • INSTALLATION & INTEGRATION • OPERATING INSTRUCTIONS • MAINTENANCE • SERVICE

USER GUIDE

u-line.com

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, 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.

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.

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.

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.

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.

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

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.

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 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.

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.

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.”

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

passthrough hole as needed to gain clearance for
