5 OPERATION OVERVIEW
feed tube is
inserted into
material
The feed tube joins air with material and it should be plunged (and kept) in the material
supply, but allow upper section of feed tube to remain above material level.
Adjust load time. See next page for detailed instructions on control settings and options.
To allow optimum loading and longest filter life, adjust load time to fill the loader without
over filling. To identify optimal load time, operate the motor until material stops moving
and note the corresponding fill time. This means the loader is OVER FILLED. Subtract 5
seconds from the over-filled time to limit premature filter blinding.
Rotate the feed tube ring for the best air to material mixture. The best mixture of air and
material will allow material to flow efficiently, with the right proportion of conveying air,
without clogging and without rapid hose wear. Be sure material flows into loader
consistently from start to finish, without surging or floating at the pickup or loader inlet.
