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.

CAUTION

Unit can NOT be installed behind a closed cabinet

door.

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.

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.

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.

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

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.

Stainless Steel

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.

or Barkeepers Friend Cleanser®

Stainless Steel Polish and

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 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.

Troubleshooting - What to check when problems occur:

Problem Possible Cause and Remedy

Digital Display and Light Do Not Work.

Interior Light Does Not Illuminate.

Light Remains on When Door Is Closed.

Unit Develops Frost on Internal Surfaces.

Unit Develops Condensation on External Surfaces.

Ensure power is connected to the unit. If the unit is cooling, it may be in Sabbath

mode.

If the unit is cooling, it may be in Sabbath mode or manually set to off.

Lighting may be set to on; reset to with door.

Frost on the rear wall is normal and will melt during each off cycle.

If there is excessive build-up of 1/4" or more, manually defrost the unit.

Ensure the door is closing and sealing properly.

High ambient temperature and excessive humidity can also produce frost.

The unit is exposed to excessive humidity. Moisture will dissipate as humidity levels decrease.

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 (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.

Thermistor two (Evaporator):

Located on the evaporator. 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. 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 shelving.

8. Remove rear shelf clips, fronts can remain.

9. Remove thermistor cover.

10.Remove two evaporator cover screws from top of

evaporator plate.

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.
