Standard Equipment
Standard equipment consists of a self-contained
unit housing the filters, blower, clean- and dirty-air
chambers, and dust drawers. Locate the unit as
close to the dust source as possible, except where
explosive or flammable material is present.
1. Make the electrical connections to the
customer-supplied safety disconnect switch,
blower, and blower starter.
2. Turn power ON at source.
3. Turn the blower motor ON then OFF to check
for proper rotation by referencing the rotation
arrow located on the blower housing. A blower
running in the wrong direction will still deliver
approximately 40% of its rated air volume
making proper rotation extremely important.
To reverse rotation, sinÖle-phase poïer supply:
Follow manufacturer’s instructions on the
motor’s nameplate.
To reverse rotation, three-phase poïer supply:
Turn electrical power OFF at source and switch
any two leads on the output-side of the fan-
motor starter.
Optional Equipment
Hopper

3/8-16 x 1-in bolts, washers, and nuts as

front or back hopper access.
Note: The 5-gallon pail hopper does not
require cross bracing.
2. Position the hopper and leg assembly on the
foundation’s anchor bolts and fasten securely.
3. Apply 1/4-in diameter rope-type sealant to the
hopper’s top flange.
4. Lift cabinet over hopper and leg assembly and
lower slowly.
5. Secure with bolts, washers, and nuts supplied.
