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.

When connecting the water supply, please note the
following:
• Water Mineral Content:
◦
TDS: greater than 5 ppm (mg/l) but less than
400 ppm (mg/l)
◦
Hardness: Less than 200 mg/l (12 gpg)
• Not recommended for use with softened water
• A TDS meter is included with your unit

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.

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, 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
nish with Claire
®
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.

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.

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.
