Water Hookup
Water Hookup
PREPARE PLUMBING
The water valve uses a standard 1/4” (6.35 mm)
compression tting. U-Line recommends using accessory
water hook up kit – part # 80-54674-00. The kit includes
a 10’ (3 m) braided exible water supply line and a brass
hose tting.
Plumbing installation must observe all state
and local codes. All water and drain connections
MUST BE made by a licensed/qualied plumbing
contractor. Failure to follow recommendations
and instructions may result in damage and/or
harm.
Water Supply Connection
When connecting the water supply, please note the
following:
• Before installing the unit and connecting to the cold
water supply, review the local plumbing codes.
• The water pressure should be between 20 and 120 psi
(138 and 827 kPa).
• TDS (Total Dissolved Solids) between 5 ppm (mg/L)
and 400 ppm (mg/L) and water hardness less than 200
mg/L (ppm), 12 gpg (grains per gallon).
• TDS and/or water hardness above these limits should
be treated with a reverse osmosis system or other
ltration system.
• Softened water is not recommended as it may result in
softer ice than desired.
• The water line MUST have a shut-o valve in the
supply line.
• The water line should be looped into 2 coils. This
will allow the unit to be removed for cleaning and
servicing. Make certain that the tubing is not pinched
or damaged during installation.
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 exible 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,
ooding or void the product warranty.
Use new hose set. Do not reuse old hose set.
Turn o water supply and disconnect electrical
supply to unit prior to installation.
Use caution when handling back panel. The edges
could be sharp.

Drain
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 oor drain must be large
enough to accommodate drainage from all
attached drains. Follow these guidelines when
installing drain lines to prevent water from
owing back into the ice maker storage bin and/
or potentially owing onto the oor, which may
result in personal injury or property damage
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).
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 ttings are free from
leaks.
This equipment is to be installed with adequate
backow protection to comply with applicable
federal, state and local codes
Model numbers including “CL” or “NB” do not include a
factory installed drain pump.
Model numbers including “CP” or “NP” include a factory
installed drain pump.
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.
2. Connect to your local plumbing per the local code.
3. If necessary, insulate drain line to prevent
condensation.

HANDLELESS INTEGRATED DOOR PANEL
The following procedure is designed to provide a finished,
handleless solid panel for an 15" (381 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 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.
NOTICE
The integrated panel aligns with the surrounding
cabinetry and, due to differences in cabinetry,
may not align perfectly with the door.
The appliance will need up to 34-1/2" (876 mm)
to the underside of the counter to leave room for
leveling adjustments.

Ice is produced until the machine senses the bin is full. As
ice slowly melts in the bin, the level of ice drops and ice
production resumes. This ensures a constant supply of
fresh ice is always available.
The factory default ice setting is 0, which produces a firm
and compact ice nugget. U-Line’s exclusive U-Choose™
ice adjustability feature allows you five levels of
adjustment from 0 to -5. At -5 the ice is soft and

INTERIOR CLEANING
Disconnect power to the unit.
Clean the interior and all removed components using a mild
nonabrasive detergent and warm 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
and/or odor to the interior products and damage or discolor
the interior.
NUGGET ICE MACHINE CLEANING CYCLE
This ice machine has an automatic clean alert function.
The control will indicate CL in the display, approximately
every six months with normal use, reminding you to
clean your unit. When CL is displayed, ice production will
continue. Depending on water conditions, more frequent
cleaning may be necessary: see chart below. Cleaning
removes lime scale, other mineral deposits, and sanitizes
the machine. Poor ice quality and reduced ice output are
signs that cleaning is necessary.
Clean surfaces with a mild detergent and warm water
solution. Do not use solvent-based or abrasive cleaners.
Use a soft sponge and rinse with clean water. Wipe with a
soft, clean towel to prevent water spotting.
Clean any glass surfaces with a non-chlorine glass
cleaner.
EXTERIOR CLEANING
Vinyl Clad (Black or White) Models
Stainless Models
Stainless door panels, handles and frames 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 specically 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
®
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.

SPECIFIC ERRORS AND ISSUES
The advanced diagnostic capabilities of the electronic
controls utilized on the 1, 3, and 5 Class units allow for
easy and thorough troubleshooting.
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.
Verication of temperature and thermistor performance can
be identied by directly viewing thermistor readings in the
service mode.
Component failure issues can be identied through
service mode menu #20, “Component Testing.” Individual
components can be switched on and o to check for both
proper function of a specic component and also delivery of
supply voltage to the components through the relays and
DC outputs located on the relay/power board.
Included in this section are some diagnostic tips and of
course, 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 eciency 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 oors and paneled walls have a
tendency to reect normal appliance operating noises.
Listed below are common refrigeration components with a
brief description of the normal 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 owing through an evaporator
may sound like boiling liquid.
• Condenser Fan: Air moving through a condenser may
be heard.
• Water Valve: Running water and clicking as valve
opens and closes.
• Ice Dropping: Ice falling into the bin makes a dull thud
sound. The sound decreases as the bin lls with ice.
• Solenoid Valves: An occasional clicking sound may be
heard as solenoid valves are operated.

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
ow chart below to help diagnose the issue. Before begin-
ning it is important to rst verify the unit is not simply set

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 o time between relay cycles.
2. Toggle the relay. Its related component should
activate / deactivate with the switching of the relay. If
it does not, test component.
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 conguration error. Some conguration
errors can be cleared by restoring the unit to its factory
default setting. Factory defaults may be restored through
the service menu. If that does not work, check that the
board is programmed to the correct model in 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.
PLUNGER SWITCH
ERROR CODES
A plunger switch is used to monitor door state. When the
door is closed it comes into contact with the plunger which
closes a circuit which turns the light and display o. When
the door is open the plunger moves outward 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.
*All errors are logged in memory.
*Only door error is displayed on the display and has an
audible signal.

Thermistor
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 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.
This unit has one thermistor located along the right hand
sidewall of the ice bin. It is used to maintain the ice level in
the bin.

Terms
These warranties apply only to products installed in any one of the fifty states of the United States, the District of Columbia, or the ten
provinces of Canada. The warranties do not cover any parts or labor to correct any defect caused by negligence, accident or improper use,
maintenance, installation, service, repair, acts of God, fire, flood or other natural disasters. The product must be installed, operated, and
maintained in accordance with your product’s User Guide.
The remedies described above for each warranty are the only ones that U-Line will provide, either under these warranties or under any
warranty arising by operation of law. U-Line will not be responsible for any consequential or incidental damages arising from the breach of
these warranties or any other warranty, whether express, implied, or statutory. Some states do not allow the exclusion or limitation of
incidental or consequential damages, so the above limitation or exclusion may not apply to you. These warranties give you specific legal
rights, and you may also have other rights which vary from state to state.
Any warranty that may be implied in connection with your purchase or use of the product, including any warranty of merchantability or any
warranty fit for a particular purpose is limited to the duration of these warranties, and only extends to five years in duration for the parts
described in the section related to the five year limited warranty above. Some states do not allow limitations on how long an implied warranty
lasts, so the above limitations may not apply to you.
