Water Hookup
Water Hookup
PREPARE PLUMBING
The water valve uses a standard 1/4” (6.35 mm)
compression fitting.
U-Line recommends using accessory water hookup kit -
Part # ULAWATERHOOKUP. The kit includes a 10’ (3 m)
braided flexible water supply line and a brass hose
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.
Water Supply Connection
WARNING
!
Connect to potable water supply only.
CAUTION
!
Review, obey, and understand the local
plumbing codes before you install your unit.
Connect to the cold water supply. The water
pressure should be between 20 and 120 psi (138
and 827 kPa). The water line MUST
have a shut-
off valve on the supply line.
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.
CAUTION
!
Turn off water supply and disconnect electrical
supply to unit prior to installation.

USER GUIDE
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.

ICE CUBE THICKNESS AND ADJUSTMENT
NOTICE
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.
Ice is produced in layers resulting in a clear cube. Ice in
bin may develop surface frost which disappears when cube
is placed in liquid.
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 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 becomes thicker, 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 overll the
ice bucket.
32 ice cubes are formed on a 4 x 8 slab during each cycle.
Each cycle takes approximately 15-20 minutes at the
default cube thickness (0).
Your clear ice machine is preset to produce ice between
the optimal dimensions illustrated below:
Ice thickness adjustments are made using the control
panel as follows:
1. To enter the thickness adjustment mode:
• Press and hold for 5 seconds.

NOTICE
Use only U-Line Clear Ice Machine Cleaner
(80-55667-00), available for purchase from
u-line.com or your dealer. 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 nish of the evaporator and
will void the warranty. Read and understand all
labels printed on the package before use.
U-Line Clear Ice Machine Cleaner is used to remove lime
scale and other mineral deposits. Refer to the following
steps to initiate the self-cleaning cycle.
Never use anything to force ice from the
evaporator. Damage may result.
1. Turn the ice machine o and allow any ice to melt o
of the evaporator.
2. Remove all ice from the storage bin.
3. Remove evaporator cover.
4. Remove the standpipe by
lifting it up while using
a slight back and forth
motion to loosen it from
the drain hole. The water
in the reservoir will ow
down the drain.
5. Re-install the standpipe into the water trough.
6. Clean the Interior Bin as
follows:
• Dilute 1-2 oz. of Clear Ice
Machine 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.
CAUTION
!
• Using a bottle brush, clean
out the trough drain tube
and pump tubing where
needed.
7. Turn unit on by pressing .
8. Place unit into CLEAN mode by holding for several
seconds - until you hear the cleaning mode begin.
9. When water begins owing over the evaporator
(approximately 3 minutes), pour 1-2 oz. of Clear Ice
Machine Cleaner into the water trough. The cleaning
process will last approximately 45 minutes.
10. Dilute 1 tablespoon bleach in 1 gallon of warm water.
Apply this solution to the entire inside of the storage
area. Then rinse thoroughly with water.
The unit will resume operation approximately 15 minutes
after the automated cleaning process is completed. The
water ll valve will energize, ll the water reservoir, and
shut-o after three minutes. The compressor begins to
operate and water ows over the evaporator assembly
(ice mold). Initially, the water ow 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 rst 24 hours of operation.
NOTICE
Discard all ice produced in the rst harvest.
Should power to the unit be interrupted during
the self-clean cycle, it will be necessary to
repeat the complete cleaning cycle after power is
restored.

Troubleshooting Extended
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 o time between relay cycles.
2. Toggle the relay (refer to Control Operation for a
complete list of relays). 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.

Thermistor Resistance Data
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.
Both thermistors in the unit are identical. If a thermistor
is suspected of being defective, the resistance can be
veried. 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.
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 one thermistor.
Thermistor one (Zone):
Located along the right hand side wall. It is used to
maintain the operating temperature within that zone.
THERMISTOR FAILURE
Zone Thermistor
If the zone thermistor 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.
