The importance of the Sub-Zero PRO 48
installation cannot be overemphasized. The
installation procedure should be completed by
a qualified installer.
Before you begin the installation process, it is
recommended that you read this entire Instal-
lation Instructions book. There are key details
that you should take special care to observe
during the installation. By reading these
instructions carefully, you will make the instal-
lation process easier, problem-free and, most
importantly, safe.
The installation process is identical for both
the Model 648PROG which features a glass
door on the upper refrigerator compartment
and Model 648PRO with a solid door.
Any questions or problems about the
installation should be directed to your
Sub-Zero dealer or the Sub-Zero Customer
Service Department at 800-222-7820. You may
also check the service center locator on our
website, subzero.com.
Dimensions in parentheses are in
millimeters unless otherwise specified.
