SECTION 7: PRE-OPERATION

7.1 Overview

The Rotofilter must be checked after installation to
verify that all elements are ready for operation, and
to prevent damage to the unit or other equipment.
Some components may need to be adjusted due to
shifting during the shipping or installation process.
The electrical components must be checked for
proper operation and the Rotofilter will need to run
for a 24-hour period to allow for final calibration.
Follow all sections sequentially.

7.2 Checking Fasteners

Check the fasteners that secure the screen
clamps and the support wheels. These fasteners
can loosen during the shipping and installation
processes.
