SUB-ZERO BUILT-IN USE & CARE
OPERATIONS
DOOR AND DRAWER CLOSING
Over-and-under models:
Your refrigerator door
has a door closing cam to help in closing the
door. With the door opened to about 110°, the
cam will hold in the open position if the door is
stopped. As you close the door, the cam will take
over at about 15° to help close the door.
Your freezer drawer has a self-closing mecha-
nism. The incline, built into roller assemblies on
the drawer, uses gravity to assist in closing the
drawer.
If your Built-In unit is positioned in a corner, you
may want to install an optional door stop, which
limits door opening to 90°. This door stop is pro-
vided with each Built-In model and is shipped in
a plastic bag in the grille area.
DOOR CLOSING
All refrigerator, all freezer and side-by-side
models:
Your refrigerator and freezer doors have
spring-loaded closure mechanisms. As the doors
are closed, the door closure engages to help
close and seal the doors. A 90° door stop is pro-
vided with each unit and is shipped in a plastic
bag in the grille area.
CONDENSER FAN MOTOR
All Sub-Zero Built-In models have a fan behind
the grille to cool the compressor area. This fan
runs with either compressor.
AUTOMATIC DEFROST
Your Sub-Zero unit is equipped with an auto-
matic defrost system. The refrigerator section
will defrost during each off cycle of the refriger-
ator compressor. The freezer section is con-
trolled by an energy-saving Adaptive Defrost
system, which defrosts as needed.
SOUNDS
You may hear some noises in the normal opera-
tion of the unit. Surrounding acoustics like walls,
floors and cabinets may affect the sound of your
unit. For example, a gurgling or running water
sound is probably refrigerant circulating through
the tubing. In Models ICBBI-42SD and ICBBI-
48SD, the ice dispenser motor inside the refriger-
ator door closes five seconds after either the
or key pad is released.
During the ice maker cycle you may hear the
sound of ice dropping into the container or the
water valve operating while refilling the ice
maker with water. During the freezer defrost you
may hear crackling and/or sizzling as the heat
from the defrost element clears the frost from
the freezer coil and water runs into the water
pan.
While the compressors are in operation, you
may hear a slight hum. During the start-up and
shutdown of the compressor, you may feel vibra-
tion for a few seconds.
Some of these noises may be enhanced when
the unit door(s) are open.
VACATION TIME
For extended vacations, shut off power to the
unit. Empty the unit and block the doors open
slightly. A 25 mm space will let fresh air in to
keep the interior dry and fresh.
For short vacations, remove all perishable items.
Shut off the ice maker and empty the ice bucket.
Do not change the control settings.
If the unit is put into service temporarily and
later shut off, block the doors open to allow
fresh air to circulate inside the unit. Be sure to
shut off power to the unit.
If your religious observances (Sabbath Mode)
require turning off the lights and ice maker, see
Sabbath Mode, page 8.
ICE AND WATER DISPENSER
DISPENSER WATER GRILLE
For dispenser models, a water grille at the base
of the glasswell will catch and evaporate small
spills. Because there is no drain in this area, do
not pour water into the water grille. To clean the
area, remove the water grille by pressing the
front left corner of the grille and lifting it out.
LOCK
For dispenser models, the lock feature is used to
prevent unintended ice and water dispensing.
When the dispenser is locked, all key pads on the
glasswell are deactivated to allow cleaning or to
prevent small children from using the dispenser.
To activate the lock feature, hold down the
key pad on the glasswell until the key pad lights
flash once and the red
icon is illuminated
(approximately five seconds). The lights will
remain in the state they were in before the lock
feature was activated.
To deactivate the lock feature, hold down the
key pad until the key pad lights flash once and
the red
icon is no longer illuminated
(approximately five seconds). The lights will
remain in the state they were in before the lock
feature was deactivated.
Be sure to block doors open when unit is not
in service. Moisture buildup during even the
shortest amount of run time could attack the
interior metal surfaces.
