Specifications
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
Customer Care at 800-222-7820.
