The depth of each model is 23⁄" (587). Allow for panel
thickness when planning the finished opening depth. A
minimum 3⁄" (89) finished return is required on all sides of
the opening. Framed cabinets require additional finished
filler material behind the face frame for a proper installa-
tion. 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" (51) filler strip is recommended between the
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 a showroom section of our website, subzero.com.
For questions regarding the installation, call Sub-Zero

LEVELING
Once the unit is in position, rotate the front legs clockwise
to raise and counterclockwise to lower. Rear height adjust-
ment 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 aect 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.
