Electronic Controls
The electronic controls of your Sub-Zero undercounter
unit monitors and accurately displays temperatures within
one degree of your preset temperature. It also monitors
operation of the unit and lets you know if there’s a
problem. The control panel with digital LCD display is

To adjust the temperature in the undercounter unit, press
the COLDER or WARMER key pad on the control panel.
The temperature ranges are 34°F (1°C) to 45°F (7°C) in the
refrigerator section, and -5°F (-21°C) to +5°F (-15°C) in the
freezer section of model UC-24C(I). It is normal for
temperatures to fluctuate slightly, depending on external
influences such as an open door, the degree of humidity
and room temperature.
TE PERATURE DISPLAY
The electronic controls can display temperatures in
Fahrenheit (°F) or Celsius (°C).
For model UC-24C(I), to convert Fahrenheit to Celsius,

turning the unit on, press and hold the freezer WARMER
key pad and the POWER key pad. Then, press and hold
the freezer WARMER and COLDER key pads for 15
seconds and release. A ‘C’ will appear in the temperature
readings on the LCD. Follow the same procedure to
convert from Celsius to Fahrenheit.
For models UC-24BG, UC-24R and UC-24RO, to convert

Refrigerator Storage
ADJUSTABLE GLASS SHELVES
To remove or adjust the glass shelves, first tilt the shelf up
at the front, then lift it up and out of the tracks on the rear
wall of the unit. Refer to the illustration below.
If the door is limited to a 90° opening, you will need to
clear the door shelves in order to remove a shelf. Lift and
pivot the end of the shelf nearest the door upward, and
remove.
To replace a shelf, insert it in the tracks at the rear of the
refrigerator with the front of the shelf raised slightly. As
you push the shelf in, lower the front of the shelf until it
locks into position.
I PORTANT NOTE: Use care when handling glass shelves
to prevent breaking or scratching the interior.

Wine Storage
ODELS UC-24BG AND UC-24C(I)
Undercounter models UC-24BG and UC-24C(I) feature
shelves for wine storage. The roller-assembly shelves
with three-quarter extension allow easy access to stored
750 ml bottles.
The wine storage shelves have a solid natural cherrywood
facing that can be replaced with other wood to match
your cabinetry. Details on how to replace the shelves’
wood facing can be found in the Sub-Zero design guide.
Check our website at subzero.com or call Sub-Zero
customer care at 800-222-7820.
I PORTANT NOTE: If you choose to stain or seal the
shelves’ natural cherrywood facing, be aware that some of
these substances are hazardous and will damage stored
wine.
Be sure to unload all bottles from the wine storage
shelf before removing it.

Undercounter Use & Care 10
ICE PRODUCTION
The ice maker is designed to produce enough ice for
normal family use. The timing of ice making cycles will
vary depending on load conditions, door openings and
room temperature. On average, you can expect a cycle of
ice (eight cubes per cycle) every two hours until the
container is full.
The ice maker operates on water pressure of 20 psi
(1.4 bar) to 100 psi (6.9 bar). In some cases, a reverse
osmosis water filter system may not be able to maintain
the minimum pressure.
Dispose of the first bucket of ice produced by your new
unit to ensure that pipe residue or other particles associ-
ated with new water lines are not consumed.
I PORTANT NOTE: If ice is not used regularly it tends to
fuse together. To avoid this, empty and replace the ice in
the container as needed.
Freezer Storage
ODEL UC-24CI
Model UC-24CI refrigerator/freezer features an automatic
ice maker with clear ice container.
The ice container is removed by pulling it straight out.
Reinstall using the reverse process.
ICE AKER OPERATION
The ice maker of model UC-24CI is fully automatic and
has been tested at the factory.
The level of ice in the ice container is controlled by an ice
level arm. When the container is filled with ice, the ice
level arm senses the level and shuts off the ice maker. As
ice is used, the level drops and the ice level arm signals
the ice maker to restore ice production.
To shut off the ice maker, lift the ice level arm up or to the
off position.
