This manual contains the information necessary to ensure a safe and
successful installation. Please read and comply with the section on page
9 of this manual pertaining to SAFETY. Doing so will ensure proper oper­ation of the equipment and the safety of all personnel.

Before discarding shipping container, please inspect it thoroughly and
verify that all parts ordered are accounted for. Sometimes smaller parts
become stuck under carton flaps and other packaging materials.

PRE-INSTALLATION CONSIDERATIONS

Choosing a Location: (See Figure 1)

1) Material Flow - When selecting a location for any rotary pad-

dle bin monitor, choose a point in the vessel where the paddle
will be out of the direct flow of incoming and outgoing materi­al to prevent any mechanical damage that may be caused by
the pressure of the flow. This is particularly important for
materials with large, lumpy characteristics.
must be positioned at a point where incoming material will
reach and cover the paddle in its normal flow, and when
receding, will flow away from the paddle in an even manner.

2) Vibration Concerns - Mount at a location that is subject to
limited vibration, away from bin vibrators thereby attaining
maximum operational life. Consult the factory when ques­tionable conditions exist.

3) Guard Reinforcement - When using shaft extensions and
guards in top mounted applications, select a location where it
is feasible to reinforce the guard to the vessel wall. See
Mechanical Installation portion of this bulletin for further
details.

flow characteristics. This baffle can be created using a number
of materials including angle iron, welded plates and pipe sec
