LEVELING INFORMATION

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 DOOR PANEL

The following procedure is designed to provide a finished,

handleless solid panel for a 24" (600 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 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 door.

The integrated panel 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 dimensions below.

replace the hinge cover.

1. Open door approximately 90°.

3. Once cover is removed, slide hinge pin into hole as

shown. Pin should slide into place, stopping the door at

90°; if the pin does not go into the hole shown, hold

the door less than 90° open and try again.

4. To fully seat the pin, tap it lightly with a hammer.

2. Remove hinge cover by lifting top and bottom of hinge

cover and sliding the cover inwards to remove from

hinge.

5. Carefully slide your unit back in place.

The pin can be removed to return the door swing

back to its original 115° swing by tapping the pin

out from the bottom of the hinge.

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, which can be purchased from U-Line

Corporation (Part Number 173348). 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.

®

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

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.

• 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.

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

for assistance.

Troubleshooting - Extended 1

USER GUIDE

NOTICE

u-line.com

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

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.

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.

2. Toggle the relay. Its related component should

activate / deactivate with the switching of the relay.

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.

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.

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.

To access Relay Toggle:

1. Press to select “Relay Toggle”.

2. Press .

3. Press and to scroll through each relay or DC

output.

4. Press to toggle.

5. To exit the Relay Toggle menu, press to select

“Return to Menu” and press to confirm.

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.

THERMISTOR FAILURE

Zone Thermistors

If the zone thermistor in the unit fails the unit will continue

to cool in a back up mode to preserve the integrity of the

contents. The unit will cycle on for ten minutes, then shut

down for forty five minutes. The process will repeat until

the problem is corrected. All other functions of the unit

will continue to operate normally.

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. The error will be displayed in

the service mode “Error Log.”

This unit has two thermistors. Thermistor one is located

along the right hand side wall inside of the unit and is used

to maintain temperature within the unit.

Thermistor two is located on the back of the evaporator

and is used for defrost purposes.

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 die electric grease to all

of our thermistor connections. Die electric grease will help

to keep thermistor connections clean and dry.

If you change a thermistor in the unit please re-apply die

electric grease to the connection. If you encounter a dirty

thermistor connection, you should replace the thermistor

and the thermistor harness.

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.

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.

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 rear cover 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 internal bins and bin holders from slide

assemblies.

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

slid assemblies. The slides can pivot down from the

front mounting screws providing ample space to

remove evaporator cover.

9. Remove thermistor cover.

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.

10.Remove two evaporator cover screws from top of

evaporator cover.
