hank 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,
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 at the end of this guide and refer to it should
service become necessary.
This use & care guide 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. Simi-
larly, 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.

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 refrig-
erator 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. Tempera-
tures 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.
To adjust the temperature in either section, press the
COLDER or WARMER key pads on the control center.

Air Purification System
All Sub-Zero built-in models (except model BI-36F) include
an advanced air purification system. This system reduces
bacteria, odors, and even ethylene gas, which causes
premature ripening in fruits and vegetables. The air purifi-
cation cartridge has been factory installed and is located
inside the refrigerator, on the right-hand side of the back
wall.
The air purification cartridge will last for approximately one
year. The indicator will flash in the control center
display panel when it needs to be replaced. To replace the
cartridge, grab the outside cover from the bottom and pull
it forward. It will flip up and expose another flap and the
cartridge. Refer to the illustration below. Pull the flap
forward from the top, which will cause the cartridge to pop
out of position. Remove the cartridge.
To replace, put the new cartridge into place, with the
connector pointing down. Once in place, close the flap
until you hear a click. Then flip down the outside cover
until it closes against the wall.
Once the air purification cartridge has been replaced,
press the PURE AIR keypad on the control center for five
seconds. This will reset the air purification indicator and
will no longer be displayed.
REPLACEMENT CARTRIDGES
Replacement air purification cartridges can be ordered by
calling 800-222-7820 or online at subzerowolfstore.com
or subzero.com.
IMPORTANT NOTE The warranty for the air purification
cartridge supplied with the unit only covers defects in

Built-In Use & Care 18
Water Filtration System
All Sub-Zero built-in models except models BI-36R and
BI-36RG feature a microbiological water filtration system
that supplies filtered water to the ice maker and water
dispenser to produce great-tasting water and ice. The
water filter has been factory installed behind the grille
assembly. Refer to the illustration below.
When using the water filter for the first time, it is necessary
to clear any air from the water system and allow the filter
to assist in cleaning the water lines. For non-dispenser
models, this is done by discarding the first two full
buckets of ice. For dispenser models, dispense multiple
glasses of water for a period of two minutes.
IMPORTANT NOTE Water system and installation must
comply with applicable state and local regulations.
WATER FILTER CARTRIDGE MONITOR
It is important that the operation, maintenance and filter
replacement requirements be carried out as scheduled.
The water filter cartridge is rated for 235 gallons (890 L)
or one year, whichever comes first. The electronic control
system monitors the life of the water filter cartridge and
indicates when it needs to be replaced.
WATER FILTER CARTRIDGE REPLACEMENT
When it is time to replace the water filter cartridge, the
indicator will be visible in the control center display panel.
Follow the steps below to replace the water filter
cartridge
1) To access the water filter, pull out on the bottom edge
of the grille assembly and tilt the grille frame forward.
2) To remove the old filter cartridge, simply push the
cartridge in and pull it out. Refer to the illustration
below. There will be water in the filter cartridge, so it is
normal for a small amount to spill out.
3) Remove the new filter cartridge from its packaging and
carefully remove the plastic caps.
4) Line up the cartridge so that the locking tabs can be
inserted into the filter head.
5) Push the cartridge in until you hear a ’click’. The new
cartridge is securely installed if it cannot be removed
by pulling on it slightly.
6) Once the filter cartridge has been replaced, press and
hold the filter reset button for five seconds in order to
reset the water filter life monitor. The filter life monitor
has been successfully reset if the indicator is no
longer displayed in the control center display panel.
Refer to the illustration below.

WATER FILTER CARTRIDGE REPLACEMENT
IMPORTANT NOTE For non-dispenser models, the first
two full buckets of ice produced should be discarded after
the new filter cartridge has been installed. Allow 24 hours
before discarding the first bucket of ice. For dispenser
models, dispense several glasses of water for a period of
two minutes. This will help clean the water system and
clear air from the line.
Although it is designed to last for up to one year of use,
the actual life of the filter cartridge may vary with water
supply conditions. Therefore, it is recommended that the
filter cartridge be replaced when the indicator is
displayed, if the ice cubes become hollow or smaller, or
the water flow from the dispenser has slowed significantly.
IMPORTANT NOTE The warranty for the water filter
cartridge supplied with the unit only covers defects in
materials or workmanship and not replacement due to
normal use.
REPLACEMENT WATER FILTER
Replacement Sub-Zero microbiological water filter
cartridges (7005017) can be ordered by calling
800-222-7820 or online at subzerowolfstore.com.
FILTER REPLACEMENT OPTIONS
Due to advanced water filter technology, poor water
conditions can significantly shorten the life of a microbio-
logical filter cartridge. An alternate water filter cartridge
(7009931) is available for these instances.
IMPORTANT NOTE The alternate filter does not provide
microbiological or chemical filtration but can help alleviate
the inconvenience of frequent filter replacement while
providing basic chlorine, taste, odor and particulate filtra-
tion. We recommend contacting your local water treatment
professional before you select this filter option.
If you choose not to utilize the water filter, the system
can be placed in water filter bypass mode. A separate
bypass plug (7011209) is required and is available by
contacting Sub-Zero at 800-222-7820 or online at
subzerowolfstore.com
IMPORTANT NOTE A reverse osmosis water filter system
may not maintain the minimum water pressure needed for
the water filter to operate properly. It is recommended that
a water filter bypass plug be used for these instances.

Ice and Water Dispenser
For dispenser models BI-42SD and BI-48SD, the auto-
matic ice and water dispenser gives you both ice and
chilled water without having to open doors.
ICE DISPENSER OPERATION
To operate the ice dispenser for models BI-42SD and
BI-48SD, set a glass on the water grille of the glasswell,
and press and hold the ICE key pad on the glasswell until
you have the ice you need. For larger quantities of ice,
open the refrigerator door and place an ice container
under the dispenser chute, then press the BULK ICE key
pad on the left-hand wall inside the refrigerator section.
Refer to the illustrations below.
After initial ice maker start-up, discard the first few batches
of ice, they may be discolored by the new plumbing.
ICE DISPENSING
Models BI-42SD and BI-48SD have a feature that limits
the maximum amount of ice that is dispensed each time
the ICE key pad on the glasswell is pressed.
To dispense ice, hold down the ICE key pad for approxi-
mately two seconds. The dispenser will meter out ice for
about two seconds, collect the ice directly above the
glass, then drop the ice into the glass. If less ice is
desired, hold the ICE key pad down for less than two
seconds. If more ice is desired, hold the ICE key pad
down until the dispensing cycle repeats.
Built-In Use & Care 20
Use a sturdy glass to catch ice crescents. Fragile
glasses can break. Also, to avoid breakage, make
sure that the glass is sitting vertically on the water
grille.
IMPORTANT NOTE Be sure that dispenser key pads are
clean and dry when pressed to avoid problems with the
dispenser operation.
ICE DISPENSER OPERATING TIPS
•If there’s no ice, make sure the ice maker system is
turned on and indicator is illuminated in the control
center display panel.
•Make sure that the water filter cartridge is in place or
that the water filtration system is in bypass mode.
A separate bypass plug is required to bypass the
water filtration system. This bypass plug (7011209) is
available through your authorized Sub-Zero dealer.
Refer to the installation instructions provided with the
bypass plug.
•Make sure there is a supply of ice in the ice bucket.
See ice bucket removal, page 15.
•Make sure the ice bucket is all the way in and engaging
the auger motor at the back of the bucket. If it is not all
the way back, push on the ice bucket and press the
ICE key pad on the glasswell at the same time.
•Press the ICE key pad on the glasswell. If you do not
hear auger motor noise, wait five minutes, then try
again. If you do not hear auger noise after the second
try, call your Sub-Zero authorized service center.
•If the ice dispenser is not used for a long period, the
ice may fuse together. To avoid this, empty the ice
bucket as needed.
