a
These measurements assume that the autoloader is installed in accordance with the instructions in this manual.
b
The autoloader is in its original packaging. The packaging is designed to protect the autoloader from condensation caused by extreme
temperature variations (15° C or more). When the autoloader is moved from a cold storage environment to a warm operating
environment, it must be acclimated in its packaging for at least 12 hours before opening to prevent serious condensation damage
from occurring.
