Water Hookup
PREPARE PLUMBING
The water valve uses a standard 1/4" (6.35 mm)
compression fitting. U-Line recommends using accessory
water hook up 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 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.
Use caution when handling back panel. The
edges could be sharp.
1. Turn off water supply and disconnect electrical supply
to product prior to attempting installation.
2. Remove the grille/access panel in the front and the
back panel.
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.
!
CAUTION
3. Locate water
valve in the front
of the unit and
thread water
supply line
through.
NOTICE
Route the water
supply line
through the unit so it does not come into contact
with any internal components other than the
solenoid valve. Normal operation creates some
vibration. A water supply line contacting an
internal component or cabinet wall can cause
excessive noise during operation or damage to
the line.

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.

The maximum lift for the drain pump is
10 feet. This must be done as close to the rear of
the unit as possible.
If your drain line will run up to a stand pipe, disposal
or spigot assembly, or does not otherwise meet the
requirements for a gravity drain, you may have ordered a
factory installed drain pump.
If you need to install a drain pump into your unit, see
DRAIN PUMP section in the User Manual.

ICE CUBE THICKNESS 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 “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.
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 pre-set to produce ice between
the optimal dimensions illustrated below:

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.

Use only a refrigerant grade R-600a from a properly
labeled container.
RECOVERING/RECLAIMING R-600A
(R-600a has been exempted from recovery/reclaiming
requirements by the US EPA)
Recovery/Reclaiming equipment must be approved for use
with R-600a.
Ensure the evaporator is at room temperature prior to
recovery/reclaiming R-600a.
Use a common piercing pliers or piercing valve to remove
R-600a from the compressor process tube. (Note: Piercing
devices must not be left on the system and must be
replaced with a Schrader type valve.)

SAFETY • INSTALLATION & INTEGRATION • OPERATING INSTRUCTIONS • MAINTENANCE • SERVICE
Evacuate/reclaim via the piecing pliers to ensure the
system is empty of R-600a before any system work is
performed.
The recovery cylinder must be evacuated (no air inside)
prior to accepting R-600a.
The recovery cylinder must not be filled more than 45%
safe fill level and refrigerants must not be mixed.
The recovery cylinder must be clearly marked with R-
600a and Flammable Warning labels.
Ensure proper ventilation during recovery/reclaiming of R-
600a.
Start vacuum pump/recovery pump prior to piercing the
compressor process tube.
Follow recovery/reclaim OEM instructions for the specific
equipment used.
SYSTEM REPAIR
Ensure no residual R-600a refrigerant is left within the
system prior to repair (simple venting is not sufficient).
Evacuate and charge with dry nitrogen for leak checks.
Repair leaks or replace system parts as required.
When re-brazing, the system must be purged with dry
nitrogen and at least one access point open to the
atmosphere.
When re-brazing, proper ventilation is required along with
constant monitoring for the presence of R600a refrigerant.
The filter dryer must be replaced any time the sealed
system is serviced.
No system should be open to the atmosphere for longer
than 15 minutes to avoid moisture migration into the
system components.
LEAK DETECTION
After removal of the R-600a, the unit can be charged with
dry nitrogen or helium.
Electronic leak detection or soap solution can be used to
check for nitrogen/helium leaks.
Never use a halide torch or lighted match to check the
system for leaks at any time.
The high side of the refrigeration system (compressor
discharge to outlet of drier) must be leak tested with the
compressor running.

SAFETY • INSTALLATION & INTEGRATION • OPERATING INSTRUCTIONS • MAINTENANCE • SERVICE
The low side of the refrigeration system (evaporator,
compressor and suction line) must be leak tested with the
compressor off (equalized pressure).
RECHARGING
No air is ever to be allowed inside the refrigeration system
(R-600a refrigerant or dry nitrogen only).
Never use a torch on a fully charged refrigeration system.
Install a Schrader Type access port on the compressor
process stub.
Evacuate the system to 100 microns prior to charging.
Weigh in the R-600a charge using a refrigerant scale. (run
compressor an extra two minutes to clear the charging
hoses).
Seal the Schrader Type access port, a proper cap and seal
must be used to close the system.
SUMMARY
Safely handling R-600a requires proper procedures and
training.
R-600a approved service tools must be used.
R-600a labeling must not be removed or altered.
Proper ventilation during service is required.
Never apply a torch to a charged R-600a refrigeration
system.
Use OEM replacement service parts and do not alter the
construction of the unit.
