Caution
The library must be installed on a level, hard-surfaced floor such as cement or tile.
Never install it on carpeted flooring.
Caution
When the library is moved from a cold environment to a warm environment, it
should not be powered on for at least 24 hours. This adjustment period prevents
condensation damage.

Storing
a
and Shipping (Non-Operating) Environment Specification
a. The library is in its original packaging. The packaging is designed to protect the library from
condensation caused by extreme temperature variations of 27° F (15° C) or more. When the library is
moved from a cold storage environment to a warm operating environment, it must be acclimated in its
packaging for at least 24 hours before opening to prevent serious condensation damage from occurring.
