filler material behind the face frame for a proper installation. Refer to the illustration.
DUAL INSTALLATION
If two units are installed side by side, a dual installation kit
may be required. Installations without a custom filler strip
require a dual installation kit. If a dual installation kit is not
specified, a 2"

units. Dual installations without a filler strip can only be
accomplished using two units with opposite hinges. Refer
to the illustrations below.
Dual installation kits are available through an authorized
Sub-Zero dealer. For local dealer information, visit the find

CAUTION
Before moving the unit into position, secure the door
closed and protect any finished flooring.
WARNING
When positioning the appliance, ensure the supply
cord is not trapped or damaged.
Use an appliance dolly to move the unit near the opening.
If the unit has been on its back or side, it must stand
upright for a minimum of 24 hours before connecting
power.
Plug the power cord into the grounded outlet. For model

LEVELING
Once the unit is in position, rotate the front legs clockwise
to raise and counterclockwise to lower. Rear height adjustment can be made from the front. Using a Phillips drive,
turn clockwise to raise the unit or counterclockwise to
lower. Use the lowest torque setting when using a power
drill. Do not turn the leveling legs by hand. Refer to the
illustration below.
When the unit is properly leveled, door adjustments are
less likely to be necessary.
IMPORTANT NOTE: Level the unit to the floor, not the
surrounding cabinetry. This could aect the operation of
the unit, such as door closing.
WARNING
To reduce the possibility of the unit tipping forward,
the front leveling legs must be in contact with the
floor.

DOOR PANEL INSTALLATION
Typical panel dimensions are based on an 34⁄"
ished height with ⁄"
(3) reveals. Placement of the template
(876) fin-
must be adjusted for panels exceeding the typical dimensions.
Place the panel face down on a protected work surface.
Position the template flush with the top and sides of the
panel. Verify the correct side of the template is being used,
then mark and drill holes. Refer to the illustration below.

Use a Torx drive to partially insert a #8 x ⁄" screw into the
second hole from the top on each side of the panel. The
screws should be approximately ⁄"
(4) proud of the panel
and will support the weight of the panel during installation.
Align the support screws on the back of the panel with the
slotted holes on both door mounting brackets. Refer to
the illustration below. Opening the door slightly may help
with alignment. Once the panel is supported by the screws,
partially insert a #8 x ⁄" screw into the second hole from
the bottom on each side of the panel, but do not tighten.
CAUTION
As reveals between cabinetry and the unit decrease,
severe finger pinching can occur while the door is
closing.

DOOR PANEL ADJUSTMENT
Close the door. Make any necessary adjustments to align
the panel and reveals.
For side-to-side adjustment, move the panel side to side,
then install and tighten all mounting screws.
For up-and-down and in-and-out adjustments, slightly
loosen the bracket screws. Depending on the level of
adjustment required, it may be helpful to loosen all of the
bracket screws which will allow for maximum adjustment.
Once the bracket screws are loosened, use a wrench to
rotate the cams to make adjustments. After the adjustments have been made, tighten all bracket screws. Refer to

DOOR TRIM INSTALLATION
After the door panel has been adjusted, install the decorative side trim to the door. To install, start at the top
and align the trim with the front and rear flanges on the
bracket, then snap into place by pushing the trim toward
the back of the panel. Once the top is secure, continue the
installation downward until the remaining trim is completely secure. Refer to the illustration below.
SIDE TRIM INSTALLATION
Install the decorative trim strip to the handle side of the
unit. The side trim snaps over the brackets attached to the
handle side of the unit. Refer to the illustration below.
KICKPLATE INSTALLATION
The kickplate must be removable for service. The floor
cannot interfere with removal. Finger-tighten the adjustment bracket nuts. Refer to the illustration below. Make
in-and-out adjustments, then wrench-tighten the bracket
nuts. Install the kickplate with the provided screws.
A decorative kickplate can be attached to the factoryinstalled kickplate. The three rows of vented louvers
cannot be covered. A decorative kickplate cannot be
attached to the outdoor model.
To install a decorative kickplate, remove the paper backing
from the magnets and attach the decorative kickplate to
the magnets. The magnets allow the decorative kickplate
to be removed if necessary.
