SECTION 3: UNPACKING
All AEROMIX TORNADO
®
aerators are inspected and tested at our factory prior to
shipment to assure that each aerator meets our quality standards. Be sure to inspect
the aerator for dents, scratches or any other damage that may have been caused in
shipping. Turn the propeller by hand to make sure it rotates freely without binding.
Minor binding resulting from bumps in shipping and handling can usually be remedied by
a thoughtful adjustment of the four propeller-end bolts attaching the draft tube to the
bearing support tube. These bolts require a 9/16 inch wrench and are easily accessed
(See
FIGURE 16
). The four similar bolts on the motor end of the draft tube do not
need adjustment. Simply tighten and loosen opposing pairs of the bolts in tandem to
again make the machined "collar" of the
propeller concentric within the draft tube. It
may require some experimenting with
adjustments to these two pair of bolts, but the
binding will be quickly and easily remedied.
(Note: Re-apply Loktite to the bolts whenever
removing and reinstalling them.) Uncorrectable
binding may be caused by a bent shaft, often the
result of the aerator being dropped onto its
propeller during shipping and handling. Check all
the aerator bolts for tightness. Report any
damage to the freight carrier, equipment
distributor and AEROMIX.
SECTION 4: MOUNTING THE AERATOR
All AEROMIX mounting accessories require mounting cradles as illustrated in
FIGURE 4
below. Mounting the aerator simply consists of lowering the unit so the motor mount
pins set in the mounting cradle slot. A bolt, lockwasher, and flatwasher is tightened into
the semicircular slots on each side of the aerator. The semicircular slot allows the
aerator to be mounted in nearly any position from vertical to horizontal. Mounting
cradles are included in float or with mount kits.
Recommended tilt angle for general wastewater
applications is 45º from the horizontal. In some
applications, larger or smaller angles may be called
for to optimize the air aspiration rate and mixing
profile. Smaller angles maximize horizontal mixing
but reduce bubble hang time – larger angles mix
more deeply but reduce slightly the amount of air
aspirated. When angles smaller than 35° are used
to mount the aerator, vortex/cavitation shields may
be needed.
