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.

Unit can NOT be installed behind a closed cabinet

door.

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.

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 FRAME

The following procedure is designed to provide a finished,

handleless frame for an 18" (45 mm) door that seamlessly

integrates with its surrounding cabinetry.

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 frame solution wherein the size of the frame

may result in a height dimension taller than what we

specify. This can be achieved provided the additional

height is positioned above the appliance door.

The integrated frame aligns with the

surrounding cabinetry and, due to differences in

cabinetry, may not align perfectly with the door.

3. Prepare the insert(s) that will back up the handleless

design. Wooden Insert – Cut 1/8" (3 mm) thick

wooden insert(s) to the appropriate dimensions below.

LOOKING BEHIND THE LABEL

To most, wine is a delicious mystery. We purchase it,

uncork it, and savor its taste and beauty. But there is so

much more to true wine appreciation. Many secrets are

simply too good to keep bottled up.

WINE SELECTIONS SUGGESTIONS

Selecting the right wine for the right occasion can

sometimes be a seemingly awkward or difficult task for

the beginning wine enthusiast. We would therefore like to

present you with a few suggestions which may provide a

little more confidence and enjoyment when choosing and

serving your wines.

When selecting wines, keep an open mind and do not be

afraid to be adventurous. Do not view the subject of wine

so seriously it discourages you from learning and

discovering for fear of embarrassment if something is

incorrect. Wine is best viewed as a hobby and enjoyed.

When assembling your collection, try not to become

obsessed with “Vintages.” Although a chart can be a useful

tool, generalizations about a specific year have led more

than one collector to disappointment. Often an “Off Year”

will provide a better value and more drinking enjoyment.

The primary guideline to the subject of wine is your own

palate. Do not be afraid to make mistakes. Experiment,

discover, but most of all, enjoy yourself and your new U-

Line product.

Matching Food and Wine

Although there are no hard fast rules for matching wine to

food, observe some guidelines. Delicate dishes should be

accompanied by lighter more delicate wines. Full-flavored

foods should be matched with fuller-bodied wines.

As a general rule, one should aim to ascend in flavor and

quality of wines served.

Serve a: Before a:

DRY wine SWEET wine

WHITE wine RED wine

YOUNG wine OLD wine

Any step back in quality will be noticed. If a fine wine is

tasted prior to a lesser wine, many of the fine wine’s

subtle qualities may be missed.

A Toast to Wine Truths

Like the grapes themselves, many wine myths have been

cultivated over the centuries.

Myth 1: Most wines taste better when aged.

Truth: In fact, less than 5% of wines produced today are

meant to be aged. Most wines are crafted to be consumed

within the first one to two years.

Myth 2: Wines should be uncorked and decanted allowing

them to “breathe.”

Truth: To breathe or not breathe? While it is better to

allow a young tannic Red to breathe in a glass or decanter

to soften the tannins, an old Red reaches a stage in its life

where it should be enjoyed soon after opening. Allow an

old Red to breathe for a short time to dissipate any off

odors. Most white wines can be served, ideally, 10-15

minutes after opening.

Sparkling or Extra Dry

The Cork: A Mystery on Its Own

Cork Presentation. The ritual of the presentation of the

cork has a rich and fascinating history dating back to the

late 1800’s. A phylloxera (root louse) devastation to the

vineyards severely limited the supply of great wines.

Restaurateurs would remove labels on inferior wines and

replace them with labels from superior wines. This made it

necessary for patrons to protect themselves by checking

the branding on the cork to ensure that what they ordered

was, in fact, what they were served.

When presented with a cork today, feel it to check for its

integrity, read and match the branding on the cork to the

bottle and set it aside. There is little to be learned from

the cork. The proof is in the wine.

“Corked” wines. If you’ve ever had a wine that smelled or

tasted of mold, you’ve experienced a wine that may have

been “corked.” Today, between five and eight percent of

wines are tainted with Trichloroanisole (TCA). This

substance, found naturally in plants and trees, is imparted

to the wine through the cork. Corked wines are a major

concern for winemakers as it destroys millions of cases

per year and puts reputations at stake. Amazing as it may

seem twist-off caps may offer a better alternative and

many great wineries in California, Australia and New

Zealand are pioneering the trend.

Myth 3: When age worthy wines peak, they must be

consumed almost immediately.

Truth: Most great wines reach a plateau period rather

than a peak. Great Bordeaux’s may have as much as a

10-year plateau before fading.

Myth 4: Wine color does not change with aging.

Truth: As red wines age they get lighter in color while

whites get darker.

Common Tasting Terms IDEAL WINE STORAGE CONSIDERATIONS

Terminology Description

Acidity A critical element of wine that is responsible

for preserving the wines freshness. Excess
acidity results in an overly tart and sour
wine.

Balance A desired trait where tannin, fruit and acidity

are in total harmony. Wines with good
balance tend to age gracefully.

Body The weight and presence of wine in the

mouth provided by the alcohol and tannin
level. Full-bodied wines tend to have this
strong concentration.

Bouquet The blending of a wine’s aroma within the

bottle over a period of time, caused by
volatile acidity.

Complex A subjective term often used in tasting. A

wine is said to be complex if it offers a
variety of flavors and scents that continue to
evolve as it develops.

Flabby A wine that lacks structure, or is heavy to

the taste, lacks acidity.

Full-Bodied Wine high in alcohol and extract, generally

speaking, fills the mouth, powerful.

Lean Generally describes wines that are slim,

lacking of generosity or thin.

Oaky A desirable flavor imparted to wine if done in

moderation. Most wines are aged in oak
barrels one to three years, thereby receiving
this toasty oak characteristic. However, if a
weak wine is left in contact too long with an
oak barrel it will tend to be overpowered with
an oaky taste.

Tannin Tannins are extracted from the grape skins

and stems and are necessary for a well-
balanced red wine. Tannins are easily
identified in wine tasting as the drying
sensation over the gums. Tannins generally
fade as a wine ages.

Temperature: The most important element about

storage temperature is stability. If wine is kept in a stable

environment between 40°F (7°C) and 65°F (21°C), it will

remain sound. A small 1-2 degree temperature fluctuation

within a stable environment is acceptable. Larger

temperature fluctuations can affect the corks ability to

seal, allowing the wine to “leak” from the bottle.

Humidity: The traditional view on humidity maintains

that wines should be stored on their sides in 50% - 80%

relative humidity to ensure cork moisture and proper fit in

the bottle. Contemporary wisdom suggests that the cork

surface is too small to be impacted by humidity. Further

the cork is sealed with a metal or wax capsule making

humidity penetration impossible. The concept of a humid

storage environment was derived from the necessity of

wineries to maintain moisture in their cellars to keep

wooden barrel staves swollen, preventing wine

evaporation and product loss. In fact, vineyards estimate

as much as a 10% product loss per year due to

evaporation while wine is aging in the wooden barrels.

Humidity, however, was not intended for the modern

home cellar where wine is stored in glass bottles with

sealed corks.

Light: UV rays are not only harmful to people, they are

damaging to wines - especially those in clear bottles.

Since oxygen molecules in wine absorb UV rays, wine

should never be stored in direct light for long periods of

time.

Vibration: Provided that sediment is left undistributed

and particles are not suspended, vibration in a storage

environment is not an issue. Wines can become flat or

tired when voids and vacuums are created inside the wine

bottle. In order to create voids and vacuums within a

liquid, aggressive motion or shaking of the wine bottle

would have to occur.

Wine Rack Installation

To remove wine racks for cleaning:

1. Remove any bottles stored on the rack.

2. Grasp the end of the rack and gently slide it out until it

stops.

3. The release levers are located on the inside of the rack

rails. Press the left rack release lever down. At the

same time, lift the matching right rack release lever

up. Pull the rack out until it is free of the tracks and

the cabinet.

To insert wine racks in the cabinet:

1. Align the left and right rack channels with the tracks in

the cabinet. Ensure an even track engagement on both

sides by gently pushing the rack into the cabinet until

it stops.

2. Before reloading the rack, ensure proper movement of

the travel stops in the left and right track rails by

pulling the rack out gently until it stops.

To clean wine racks:

1. Saturate a soft cloth with a soapy, warm water

solution.

2. Wring excess water from cloth and wipe racks down.

The wine racks are greased. This white lithium

grease helps provide smooth operation of the

slide mechanism. It is important not to remove

grease.

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 interior of your

product or can be accessed through “Help” in the

Customer Menu.

• 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.

TROUBLESHOOTING GUIDE

DANGER

!

ELECTROCUTION HAZARD. Never attempt to

repair or perform maintenance on the unit

before disconnecting the main electrical power.

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.

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.

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.

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 (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.”

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.

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. Fan delay times can

be modified through the service menu.

3. Disconnect power to the unit.

4. Remove rear cover from unit.

5. Disconnect fan electrical connection at rear of unit.

6. Remove insulating foam from refrigerant line pass-

through hole as needed to gain clearance for fan plug.

7. Remove internal wine racks.

8. Remove the mounting screws from the rear only of the

slide assemblies. The slides can pivot down from the

front mounting screws providing ample space to

remove evaporator cover.

9. Remove thermistor cover.

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.

10.Remove two evaporator cover screws from top of

evaporator cover.

11.Grasp evaporator cover, pull the top forward and up as

bottom of cover is installed behind the front edge of

the drain trough.

12.While pulling the evaporator cover clear of the unit, it

may be necessary to use your free hand to manipulate

the fan plug end through the pass-through hole.
