SUB-ZERO BUILT-IN REFRIGERATION
THANK YOU
Thank you for purchasing your new Sub-Zero
Built-In unit. With Sub-Zero, you can rely on a
60-year tradition of quality and reliability. The
Built-In line brings together the latest and
finest features in home refrigeration to give
you the freshest food possible.
Sub-Zero’s design, beauty and quality are
reflected in the broad range of standard
features that put Sub-Zero in a class by itself.
The custom-design appearance of the
Sub-Zero Built-In line gives you options no
other line offers, whether you have chosen a
framed, overlay/ flush inset, stainless steel or
glass door style unit.
Your Sub-Zero is protected by a warranty that
is one of the finest in the industry. Take a
moment to read the warranty statement on
page 47 and refer to it should service become
necessary.
This Use & Care Information will answer
most of your questions about the features,
operation and maintenance of your Built-In
unit. If you have questions that are not
addressed here, call Sub-Zero Customer
Service at 800-222-7820 or visit our website,
subzero.com.
DUAL REFRIGERATION
The Built-In line continues the Sub-Zero
tradition of superior quality and reliability.
Sub-Zero pioneered the development of our
dual refrigeration system, giving you
optimum fresh and freezer food storage in
ideal self-contained sections. Both refrigerator
and freezer maintain accurate, consistent
temperatures. Dual refrigeration keeps your
food fresh longer than any other system
available.
With dual refrigeration, the freezer maintains
a constant temperature within one degree of
the temperature you set within our range of
-5˚F (-21˚C) to +5˚F (-15˚C), without unwanted
moisture and odor from the refrigerator. Similarly, you can adjust the refrigerator temperature within a range of 34˚F (1˚C) to 45˚F (7˚C),
for proper humidity levels tailored for longer
food life expectancy.
The dual refrigeration system also means
there is no transfer of fresh food odors to
frozen food or ice. The Sub-Zero system does
not freeze the moisture out of the air in the
fresh food section.
Sub-Zero dual refrigeration is also more
energy efficient than old-fashioned single
refrigeration systems. When the refrigerator
is used frequently during the day it does not
require the freezer to circulate its very cold,
dry air to the refrigerator. Instead, the refrigerator uses moist air to keep fresh foods fresh
and energy use minimal.

Classic framed models—the look that made
Sub-Zero famous—feature an innovative
grille and handle design.
Overlay models blend seamlessly into your
overall room design and complement
surrounding cabinetry.
New flush inset application allows the unit
to be flush with surrounding cabinetry.
Options include using custom panels or
Sub-Zero accessory panels in classic,
platinum and carbon stainless steel. Classic
stainless steel models feature wrapped
doors, stainless steel tubular handles and
flip-up grille, designed specifically to
enhance the aesthetics of today’s professional looking kitchens.
Models BI-36RG, BI-30UG and BI-36UG offer
a unique feature—a glass door. These units
each come in the framed, overlay/ flush
inset, or classic stainless steel design and
meet stringent energy requirements.
Glass door models add a contemporary
look that is quite unique and innovative,
with subdued interior lighting.
Shallow-depth design means access is easy
to any area of the refrigerator.
Built-In combination models have the
Sub-Zero dual refrigeration system, which
ensures the freshest food and energy efficiency at the same time. You have precise
independent control of the refrigerator and
freezer sections.
All Built-In models have a microprocessor
to give you better control, automatic
defrosting that senses, then adapts to your
use patterns, and a service indicator light.
Our microprocessor continuously monitors
each section, and should a problem arise,
the processor will turn on the
indicator in the control display panel.
Controls are up front and easy to use.
They give you digital readings for quick,
easy-to-read reference. Up-front controls
also keep you informed about the operation
of the unit on a continuous basis.
All Built-In models have a flip-up grille,
making it even easier to clean your
condenser and access your water filter.
Water Filtration—our microbiological water
filter ensures you have the cleanest ice and
water possible.
Air Purification—bacteria, odors and gases
are removed by this advanced air purification system.
Bright lighting spreads even illumination
throughout each section. The source of the
illumination is concealed.
A door alarm will let you know with an
audible chime if your refrigerator or freezer
door is left ajar.
The full-extension, high-humidity crisper
drawer(s) are large and deep, with smooth
sides and removable dividers in most
models.
The steel reinforced cantilevered glass
shelves make repositioning quick and easy.
They’re easy to clean and spill proof.
In-door shelves are adjustable in one-inch
increments for complete flexibility.
The dairy compartment is adjustable,
with one-door access. The dairy shelf is
magnetically sealed to maintain freshness.
Over-and-under models offer a full-extension freezer drawer.

Colder/Warmer
Key Pads
ELECTRONIC CONTROL SYSTEM
The Electronic Control System of your
Sub-Zero Built-In 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. You’ll find the Control Center located
in the refrigerator section of all models, except
Model BI-36F where it is in the freezer section.
Refer to the illustration below.
TEMPERATURE CONTROL
Your new Built-In unit was thoroughly
inspected and tested before it was shipped
from the Sub-Zero factory. Temperatures are
preset at 38˚F (3˚C) in the refrigerator section
and 0˚F (-18˚C) in the freezer section.
Temperatures are displayed in the Control
Center display panel.
For combination units, there are two sets of
COLDER
and
WARMER
key pads on the
Control Center, one for the refrigerator section
and the other for the freezer section. Models
BI-36R, BI-36RG and BI-36F have only one set
of
COLDER
and
WARMER
key pads.
The temperature ranges are -5˚F (-21˚C) to +5˚F
(-15˚C) in the freezer section, and 34˚F (1˚C) to
45˚F (7˚C) in the refrigerator section. It is
normal for temperatures to fluctuate slightly,
depending on external influences such as an
open door, the degree of humidity and room
temperature.
IMPORTANT NOTE:
Always allow 24 hours
for the unit to reach the temperature you set.
POWER
All Sub-Zero Built-In models feature a
POWER
key pad on the Control Center. This key pad
will turn off all electrical power to the unit.
When the power is off, the OFF indicator light
will be visible in the Control Center display
panel. This
POWER
key pad means you don’t
have to shut off power at the circuit breaker or
wall receptacle. The key pad can be used
during service or extended vacations.
To adjust the temperature in either section,
depress the
COLDERorWARMER
key pads
on the Control Center.

ELECTRONIC CONTROL SYSTEM
ALARM FEATURE
All Built-In models have an alarm feature with
an audible chime if the door is left ajar.
The alarm will sound after 30 seconds. It can
be deactivated by depressing the
ALARM
key
pad. When the alarm is activated, the indicator will be visible in the Control Center
display panel.
ICE MAKER CONTROL
Built-In models with an ice maker feature an
ICE MAKER
key pad on the Control Center.
This key pad switches the power to the ice
maker system on or off. When the ice maker
system is on, the indicator will be illuminated in the Control Center display panel. The
ice maker can also be turned on using the
MAX ICE
key pad, activating the Max Ice
feature. The indicator will be illuminated in
the Control Center display panel when this
feature is on. Use the
ICE MAKER
key pad to
shut down the ice maker during extended vacations.
SABBATH MODE (STAR-K)
All Built-In models feature the Sabbath Mode.
This is for certain religious observances where
the lights and ice maker function need to be
turned off.
To initiate Sabbath Mode, while the unit is on
press the
POWER
key pad so that OFF is
visible in the Control Center display panel.
Your unit will be off.
Then press and hold the
POWER
key pad for
10 seconds. This will turn the unit back on and
will disable the lights and ice maker. To return
the unit to normal operating conditions, press
and release the
POWER
key pad.
If you have questions about Star-K compliance,
visit www.star-k.org.
VISUAL SERVICE DISPLAY
The Control Center monitors refrigerator and
freezer temperatures as well as the ice maker
system. If there is a temperature or ice maker
problem, you’ll be alerted by an illuminated or
flashing indicator in the Control Center
display panel. The indicator may also be
illuminated if the condenser needs cleaning.
Before calling for service, please check and see
if your condenser area needs cleaning. See
Condenser Cleaning, page 28.
