Environmental Requirements
This unit is designed to operate between 50°F (10°C) and
100°F (38°C). Higher ambient temperatures may reduce
the unit’s ability to reach low temperatures and/or reduce
ice production on applicable models.
For best performance, keep the unit out of direct sunlight
and away from heat generating equipment.
In climates where high humidity and dew points are
present, condensation may appear on outside surfaces.
This is considered normal. The condensation will
evaporate when the humidity drops.

WARNING
!
Electrical
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.
u-line.com
Never use an extension cord to connect power to
the unit.
Always keep your working area dry.
NOTICE
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.
See CUTOUT & PRODUCT DIMENSIONS for recommended
receptacle location.

PREPARE SITE
Your U-Line product has been designed for either free-
standing or 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,
and clearance is required for an electrical connection in
the rear.
Unit can NOT be installed behind a closed
cabinet door.
If you would like to align the face of the unit
with other adjacent cabinet doors, you may need
to alter the wall just behind the drain connection
on the unit to accommodate the drain.

Side-by-Side Installation
Two units may be installed side-by-side.
Cutout width for a side-by-side installation is the cutout
dimension of a single unit times two.
No trim kit is required. However, 1/4" (6 mm) of space
needs to be maintained between the units to ensure
unobstructed door swing.
Units must operate from separate, properly grounded
electrical receptacles placed according to each unit’s
electrical specifications requirements.
Side-by-Side Installation with Bracket
1. Slide both units out so screws on top of units are easily
accessible.
3. Place bracket over holes and attach to unit with two
screws removed in step 2 using a T-25 Torx driver.
Tighten screws fully.
4. Gently push units into position. Be careful not to
entangle the electrical cord or water line, if applicable.
5. Re-check the leveling, from front to back and side to
side. Make any necessary adjustments. The unit’s top
surface should be approximately 1/8" (3 mm) below
the countertop.
2. Remove screws as shown below.

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.
CAUTION
!
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:
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 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.
CAUTION
!
• 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.
Turn o water supply and disconnect electrical
supply to unit prior to installation.
Use caution when handling back panel. The edges
could be sharp.

factory installed drain pump.
Model numbers including “CP” or “NP” include a factory

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 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
GRAVITY DRAIN
Normal
Proper Drain
Poor Drainage, Water Will Back Up
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.
With Trap

NOTICE
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.
CAUTION
!
This equipment is to be installed with adequate
backow protection to comply with applicable
federal, state and local codes
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).
