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.

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 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.

PREPARE PLUMBING

Please use the braided stainless steel water supply line

which comes attached. The water line is fitted with a

standard 1/4" (6.35 mm) compression fitting.

WARNING

!

Prior to installation, determine if this product

contains a gravity style drain or factory installed

drain pump. Products without a drain pump may

only use a gravity style drain. Failure to connect

water supply or drain line connections properly

may result in water leakage, personal injury,

and/or property damage. Disconnect power and

turn off water to the unit before attempting to

alter these connections. These connections are

the responsibility of the owner and must be

connected per local plumbing code. If you are

uncertain of how to safely and properly install

this product, contact a licensed plumber.

CAUTION

!

Do not use any plastic water supply line. The line

is under pressure at all times. Plastic may crack

or rupture with age and cause damage to your

home.

Do not use tape or joint compound when

attaching a braided flexible water supply line

that includes a rubber gasket. The gasket

provides an adequate seal – other materials

could cause blockage of the valve.

Failure to follow recommendations and

instructions may result in damage and/or harm,

flooding or void the product warranty.

DRAIN CONNECTION

CAUTION

!

If your U-Line unit did not come with a factory

installed drain pump you must use a gravity

style drain connection. For assistance in

determining if your unit has a pump please

contact U-Line. The floor drain must be large

enough to accommodate drainage from all

attached drains. Follow these guidelines when

installing drain lines to prevent water from

flowing back into the ice maker storage bin and/

or potentially flowing onto the floor, which may

result in personal injury or property damage.

GRAVITY DRAIN

A gravity drain may be used if:

Drain line has at least a 1" drop per 48" (approximately

2 cm drop per 100 cm) of run.

Drain line does not create traps and is vented per local

code.

1. Cut the pre-installed drain tube to length.

Drain can NOT be located directly below the unit.

Unit has a solid base that will not allow the unit

to drain below itself.

There is a possibility that hose connections may

have loosened during shipment.

Verify all connections and fittings are free from

leaks.

2. Connect to your local plumbing per the local code.

3. If necessary, insulate drain line to prevent

condensation.

CAUTION

!

Failure to connect water supply or drain line

connections properly can result in personal

injury and property damage. Gravity drain

connections must be routed downward from the

rest of the unit at the rate of 1/4" per foot (1 cm

per 50 cm).

ICE CUBE THICKNESS ADJUSTMENT

Ice thickness adjustment should only be made

one increment at a time. Allow ice maker

production to stabilize for 24 hours before

rechecking ice thickness.

Remove all ice from the storage bin.

Ice cubes in any given batch will vary, so it is necessary

to choose cubes from the sample area for comparison

when making adjustments.

The ice cube thickness is factory set for best overall

performance. The factory setting “0” is designed to

maintain an ice bridge of approximately 1/16" to 1/8"

(1.6 mm to 3.2 mm) under normal conditions, resulting in

a dimple of approximately 1/4" to 1/2" (6.4 mm to

12.7 mm) in depth. A fuller cube with less of a dimple

results in a thicker ice bridge. As the ice bridge thickens,

the tendency for the cubes to stay together as a slab

increases. A bridge thicker than 1/8" (3.2 mm) may cause

cubes to overfill the ice bucket.

Your clear ice machine is pre-set to produce ice between

the optimal dimensions illustrated below:

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.

Do not use cleaners not specifically intended for
stainless steel on stainless surfaces (this
includes glass, tile and counter cleaners).

Stainless Steel

Integrated Models

To clean integrated panels, use household cleaner per the

cabinet manufacturer’s recommendations.

INTERIOR CLEANING

Disconnect electric current 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.

CLEAR ICE MAKER CLEANING CYCLE

The 3000 series ice maker is equipped with an automatic

clean alert function. Cleaning cycles should be run as

notified. Otherwise, to maintain operational efficiency, the

unit should be cleaned every three months. Depending on

water conditions, more frequent cleaning may be

necessary. If the ice maker requires more frequent

cleaning, consult a plumber to test the water quality and

recommend appropriate treatment.

If any surface discoloring or rusting appears, clean it

quickly with Bon-Ami

a nonabrasive cloth. Always clean with the grain. Always

finish with Claire

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.

Use only U-Line Ice Machine Cleaner (Part No.

37050), available from your dealer or direct from

your local parts distributor. To locate a parts

distributor near you, visit www.u-line.com. It is

a violation of federal law to use this solution in a

manner inconsistent with its labeling. Use of any

other cleaner can ruin the finish of the

evaporator and will void the warranty. Read and

understand all labels printed on the package

before use.

U-Line Ice Machine Cleaner is used to remove lime scale

and other mineral deposits. Refer to the following steps to

initiate the self-cleaning cycle.

CAUTION

!

Never use anything to force ice from the

evaporator. Damage may result.

5. Re-install the standpipe into the water trough.

6. Clean the Interior Bin as follows:

• Dilute one packet of CLR cleaner into two quarts of

water.

• Using a sponge or cloth, clean interior of ice bin,

tubing and door. This cleaner will remove all mineral

deposits and other contaminants from the surfaces.

1. Switch the ice maker

off and allow any ice

to melt off of the

evaporator.

2. Remove all ice from

The unit will resume operation approximately 15 minutes

after the automated cleaning process is completed. The

water fill valve will energize, fill the water reservoir, and

shut-off after three minutes. The compressor begins to

operate and water flows over the evaporator assembly (ice

mold). Initially, the water flow may not be uniform,

causing uneven sized cubes or water to spill into the ice

storage bin. This is a normal situation that will correct

itself within the first 24 hours of operation.

Discard all ice produced in the first harvest.

Should power to the unit be interrupted during

the self-clean cycle, the complete cleaning cycle

will repeat after power is restored.

REFRESH KIT

Due to variations in water quality or inadequate

maintenance your unit may become excessively coated in

lime scale or calcium. U-Line offers a cost effective

refresh kit which replaces many interior components and

will return your unit to like new condition. Refresh kits

use of non-U-Line parts can reduce speed of ice

production, cause water to overflow from ice

maker mold, damage the unit, and void the

warranty.

Warranty parts will be shipped at no charge after U-Line

confirms warranty status. Please provide the model, serial

number, part number and part description. Some parts

will require color or voltage information.

If U-Line requires the return of original parts, we will

inform you when the parts order is taken. This

requirement will be noted on your packing list. A prepaid

shipping label will be included with the replacement part.

Please enclose a copy of the parts packing list and any

labor claims with your return. Please be sure the model

and serial numbers are legible on the paperwork. Tag the

part with the reported defect.

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.

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.

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.

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.

USB COMMUNICATION

The 3000 series uses an advanced USB logging feature for
system logging and diagnostics. The controller outputs 36
separate data points per second to either a USB flash disk
or transmitted over USB via TTY to a client PC. To prepare
the unit for logging, first verify the USB port is set to the
proper configuration. See “USB Port” for information on
configuring the USB port.

Flash Mode:

Suitable for logging directly to a USB fla sh disk.

The system will create a file named “uline.csv” on the
flash disk. In the event the file already exists, new data
will automatically be appended to the end of the existing
file. The file is output in a comma delineated text format
and may be viewed in a wide variety of simple text
readers or spreadsheet programs.

For information on identifying each data point, see the
“Communication Data” table.

USB Communication (PC Link)

Data can be transmitted directl y to a c lient P C via a seria l
connection. Verify the USB port is set to “PC Link”. Use a
Type A to Type A male to male USB cable to connect the
system to a Windows

®

compatible PC. It is necessary to
install communication drivers to the client PC. Drivers
may be downloaded at u-lineservice.com. Establish a
connection using a Telnet/ TTY terminal application. U-
Line recommends PuTTY. PuTTY is available for download
at u-lineservice.com. Once the connection is established,
the controller will output a series of 36 data points in 1
second increments. For informati on on identifying each
data point, see the “Communication Data” table on page
page 16.

USB Port

PC Link Mode:

Suitable for communicating directly with a PC via USB.

USB Communication (Flash)

The main control can host a wide range of flash disks up
to a maximum capacity of 8GB. After verifying the USB
port is set to “Flash”, simply insert a flash disk in to the
USB port located above the grille. The flash disk activity
light (located on the flash disk) will begin flashing
immediately as data is recorded to the drive. Data is
recorded in one second increments and is only limited by
the capacity of the flash disk.

The USB Port menu option allows the selection of a
communication mode. The 3000 Series can communicate
either via TTY to a PC or log diagnostic information
directly to a USB flash disk.

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.

There are 3 thermistors used with this model.

• Ice Bin Thermistor - Located on the right hand wall and

is used to maintain ice level in bin.

• Liquid Line Thermistor - Located on the liquid line and

is used during freeze/harvest.

• Ambient Thermistor - Located in the base of the unit on

the condenser and is used to monitor ambient air

temperatures.

This unit utilizes two type one thermistors, one in the bin

and one in the mechanical compartment.

The bin thermistor and the ambient thermistor are both

type 1 thermistors. In an ice water bath they should OHM

out at 16.5k +/-5%.

The liquid line thermistor is a type two thermistor. At 77°

it should OHM out at 10k OHMS +/-5%.

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.

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.

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.
