INSTALLATION
RECOMMENDATIONS
The importance of the Sub-Zero PRO 48
installation cannot be overemphasized. The
installation procedure should be completed by
aqualified 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.
