Electrical Requirements
Plumbing Requirements
The electrical supply should be located within the shaded
area shown in the illustration below. Follow the National
Electrical Code and local codes and ordinances when
installing the receptacle. A separate circuit, servicing only
this appliance is required.
MODEL UC-24CI
For model UC-24CI, the water supply line for the ice
maker should be located within the shaded area shown in
the illustration below. Connect the water line from the ice
maker water valve to the house water supply line. Use an
easily accessible shut-off valve between the water supply
and the unit. Do not use self-piercing valves. A saddle
valve kit is available from your authorized Sub-Zero
dealer.
IMPORTANT NOTE: The electrical outlet must be placed
so the grounding prong is to the right of the thinner
blades. The outlet must be flush with the back wall.
Model UC-24RO is designed and safe for use in outdoor
applications. When installed outdoors, a ground fault
circuit interrupter (GFCI) is required to reduce the risk of
electrical shock. A GFCI is not recommended for use with
other undercounter models and may cause interruption of
operation.
A line filter is required when water conditions have a high
sediment content. The ice maker operates on water
pressure of 20 psi (1.4 bar) to 100 psi (6.9 bar).
A reverse osmosis system can be used, provided there is
a consistent water pressure of 20 psi (1.4 bar) to 100 psi
(6.9 bar) supplied to the water valve at all times. A copper
line is not recommended for this application.
Do not use an extension cord or two-prong adapter.
Electrical ground is required on this appliance.
IMPORTANT NOTE: In some cases a reverse osmosis
water filter system may not be able to maintain the
minimum water pressure consistently.

Anti-Tip Bracket
Before moving the undercounter unit into position, make
sure all opening dimensions, electrical and plumbing
requirements are complete and accurate.
To prevent the unit from tipping forward and provide a
stable installation, the unit must be secured in place
with the anti-tip bracket.
IMPORTANT NOTE: The floor under the undercounter unit
must be at the same level as the surrounding finished floor
to allow for removal of the unit for servicing.
An anti-tip bracket and hardware is provided with the
undercounter unit. Placement of the anti-tip bracket is
critical to a stable installation. The anti-tip bracket must be
installed securely.
Use an appliance dolly to move the undercounter unit near
the installation opening. Position the dolly at the side of
the unit to prevent damage to finished surfaces. Remove
and discard all packing materials and tape.
The anti-tip bracket should be attached to the wall behind
the unit with the bracket flange located immediately above
the top of the unit. Refer to the illustration below.
IMPORTANT NOTE: Do not discard the kickplate, anti-tip
bracket, hardware and the shipping bolts that hold the
wood to the bottom of the unit (leveling legs). These items
will be needed for the installation.
For installations that cannot accommodate the anti-tip
bracket, the optional countertop bracket (provided) can
be used to secure the undercounter unit. This bracket will
secure the front of the unit to the underside of the coun-
tertop, above the unit. Refer to the illustration below. If it is
not possible to use the countertop bracket, wedge shims
along the sides and top of the unit to secure.
For models UC-24BG and UC-24C(I), the roller-assembly
wine shelves should be removed to reduce weight and
prevent them from rolling. To remove, pull the shelf out to
its full extension, gently and evenly lift up on both sides of
the front of the shelf and remove. Reverse the procedure
to reinstall the shelf.
Before moving the undercounter unit into position,
protect any finished flooring with appropriate materials
and secure the door closed.

Installation
IMPORTANT NOTE: If the undercounter unit has been laid
on its back or side, you must allow the unit to stand upright
for a minimum of 24 hours before connecting power.
WATER LINE CONNECTION (MODEL UC-24CI)
For model UC-24CI, connect the plastic tubing from the
ice maker to the house water supply line with the fitting
connection kit, provided. Check all water line fittings for
leaks.
With the undercounter unit near the installation opening,
plug the power cord into the electrical outlet. With power
applied to the unit, check for lighting and cooling. Once
you are satisfied that the unit is operating properly, shut
off power to the electrical outlet at the circuit breaker and
proceed.
Purge the water line prior to final connection to the unit.
This will remove any debris that may be present in the
tubing from installing the new water line.
IMPORTANT NOTE: Let your customer know that the ice
maker will not produce ice immediately, and that the first
few batches of ice produced should be discarded. Allow
24 hours for proper ice production.
LEVEL THE UNIT
Level the unit before sliding it into position. Leveling
cannot be completed with the unit pushed back in the
installation opening.
IMPORTANT NOTE: Water lines must not be exposed to
freezing temperatures. Exposure could cause damage to
the unit and home.
Using an adjustable wrench or pliers, turn each of the four
leveling legs clockwise to raise the unit and counterclock-
wise to lower the unit. For the location of the leveling legs,
refer to the illustration.
INSTALL KICKPLATE
Install the kickplate using the two #10 x 1/2" stainless steel
screws that are provided with the kickplate. Refer to the
illustration below.
To reduce the possibility of the unit tipping forward, the
front leveling legs must be in contact with the floor.
The kickplate must be removed for servicing. The floor
cannot interfere with removal. Do not cover the louvered
section of the kickplate to allow proper air circulation.
Turn power back on to the electrical outlet.
POSITION THE UNIT
Slide the undercounter unit back into position in the
installation opening. Make sure it contacts the anti-tip
bracket for a stable installation.
The undercounter unit provides the best access to its
contents when the front surface of the door panel extends
out from surrounding cabinets approximately 1/4" (6).

IMPORTANT NOTE: Model UC-24RO must be built into
cabinetry and cannot be used in a freestanding applica-
tion.
For overlay model UC-24BG/O, a decorative frame door
panel must be provided to surround the glass. The inside
edges of the panel that will be visible through the glass
must be finished. Refer to the chart for panel specifica-
tions.
You may also use your own handle hardware to match sur-
rounding cabinetry. If you do not use the pre-drilled holes
on the door of the unit, you will need to attach the handle
directly to the overlay panel.
IMPORTANT NOTE: For installations at or above 5,000'
(1524 m) in altitude, a special high altitude glass door unit
must be ordered.
A solid panel must not be installed over the glass door,
as this may cause moisture to form behind the panel.

Overlay Panel Installation
MODELS UC-24R AND UC-24C(I)
Before attaching the overlay panel to the door, insert two
screws, one in the center of each mounting position, just
far enough that the slotted holes on the hinge side door
panel bracket will slide under the heads. These positioning
screws will support the door panel during installation and
adjustment. Refer to the illustration below.
Inspect the overlay door panel for minimum thickness and
weight limit. Remove the two panel mounting brackets
attached to the front of the door and set aside.
Place the overlay panel lying face down on a protected
surface to ensure that the front is not scratched or
damaged. Position the plastic template (provided) flush
with the lower edge of the door panel. Be sure you are
following the exact location for the right-hand (RH) or left-
hand (LH) door swing. Refer to the illustration below for
placement of the mounting brackets.
Install the door panel by engaging the tabbed bracket to
the handle side of the door first and then sliding the hinge
side mounting bracket onto the positioning screws on the
hinge side of the door. The panel can be adjusted 1/4" (6)
up and down and side to side.
Once the door panel is in place and adjusted correctly,
attach the four remaining #10 x 1/2" screws to the hinge
side mounting bracket and install the magnetic decorative
caps as shown in the illustration below.
Once you have located the proper placement for the
brackets, mark the pilot holes, remove the template and
drill pilot holes for mounting the brackets. It is best to start
with a few holes, position the bracket, drill the remaining
pilot holes and then secure the mounting bracket with the
#8 x 1/2" screws provided.
Exercise caution when drilling holes for mounting
hardware. This is especially critical with inset panels.

Overlay Panel Installation
BEVERAGE CENTER MODEL UC-24BG
Remove the door panel from the door frame and remove
tenon centers. Open the door. Using the center marks to
locate screws, drive the screws into the panel through the
black tape on the door frame.
Inspect the overlay door panel for minimum thickness,
weight limit and finished inside edges. Decide if the handle
will be attached through the glass door frame or just
through the decorative door panel. If it is just through the
door panel, the handle must be attached first.
The screw holes inside the door are hidden under a cover
flap on the door gasket. It is necessary to lift the flap to
insert the screws. Use as many screws as necessary to
hold the door panel in place securely.
The overlay door panel is attached using #8 x 5/8" square
drive screws passing through the door frame from the rear,
behind the gasket into the panel. The door panel is
marked for screw locations by the use of tenon centers,
which are temporarily inserted into the 1/4" (6) diameter
holes in the front of the door frame. Refer to the illustration
below.
IMPORTANT NOTE: After the first three or four mounting
screws are in place, but not completely tightened, close
the door and check the panel fit. This is the time to make
small adjustments. Once you are satisfied with the appear-
ance, open the door and add the rest of the screws.
Check all screws for tightness.
With the unit secured in place and the door closed, the
panel is held in the desired position on the door and
rapped by hand from the front, putting center marks on
the rear surface of the panel. If the door panel is made of
such a material that pre-drilling is needed, all of the
mounting holes should be marked. If not, only enough
holes to hold the panel in place temporarily, are necessary.
The metal frame on the door has numerous mounting
holes on each side of the door. This is to accommodate
Sub-Zero accessory handles and provide for easy attach-
ment of the handle through the door frame.
If you choose not to use the pre-drilled handle mounting
holes, it will be necessary to fasten the handle from the
rear of the door panel only, or drill one or more additional
holes through the metal frame of the door.
The cross-section illustration shows how the hole passes
through the door frame. The hole center is on the small
locator groove in the front of the frame. A 1/4" (6) diameter
hole is made in the front wall of the extrusion and a 13/32"
(11) diameter hole through the rest of the frame.

Hinge Adjustment
IMPORTANT NOTE: The undercounter unit should be
properly leveled before door hinge adjustments are made.
The model UC-24BG glass door is made with a sealed,
double-wall tempered glass core. The drill must not
contact this core when drilling. Be sure the hole is
centered on the small groove in the front of the door
frame and the drill passes squarely through the frame.
If you are inexperienced with drilling, fasten the handle
from the rear of the door panel only.
The top and bottom cabinet hinges are held in place with
three permanent adjustment screws. If the door needs
adjustment, loosen the adjustment screws and reposition
the door. Once in position, tighten the adjustment screws.
Refer to the illustrations below.
IMPORTANT NOTE: For model UC-24BG, install screws in
all the mounting holes in the door frame. The nature of the
door panel with a narrow outer rim and no connecting
center member requires the support provided by the glass
door.
