INSTALLATION AND OPERATING INSTRUCTIONS

METALFAB BIN ACTIVATORS

Description

1. Upper hanger (suspension arm) brackets are pre-assembled, at the factory,
to a flanged cylindrical section. It insures proper alignment of the suspension
arms and sleeve clamping surfaces.

2. Flanged mounting ring may be provided with bolt holes for bolting to a
mating flange on the bin.

Note: Nuts, bolts and gasketing for the mating flanges are not

supplied by Metalfab. Use high strength, grade 5 bolts
and locknuts.

3. When being installed on a conical section of a bin, it can also be welded
directly to the bin cone. The cone may be butted against the horizontal or
inside diameter of the flange and seal welded.

4. Before doing any welding, remove the vibrator from the Bin Activator.

5. In all cases, regardless of installation procedures, the mounting flange must
not be distorted or bent during installation.

6. Even though the locating of suspension brackets is done with special
equipment, it is recommended that mating parts be maintained, i.e., do not
interchange mounting flanges from one serial numbered unit with another
serial numbered unit.

7. To insure proper fit and alignment, plan view orientation of the hopper
mounting flange with relation to the Bin Activator must not be changed.

8. In most cases, generally 3 foot through 8 foot diameter units, the mounting
flange is shipped pre-assembled to the Bin Activator. For 10 foot diameter
and larger, the mounting flange is split in half and shipped on the same skid
as the Bin Activator or separately. A metal brace may be welded to each half
section to prevent distortion during shipment. If so, remove after installation.

Installation _ Assembly

1. Specific sequence of installing a Metalfab Bin Activator can be changed to
suit individual requirements. Most important is the end result, i.e., proper
alignment and tightness of nuts, bolts and sleeve clamps.

2. Plan view orientation of the vibrator location with respect to the storage bin is
not critical. It can be located to suit.

3. For units provided with bolt holes, the bolt holes can be pre-drilled in the
mating bin flange. Care must be taken to make certain that the flange is not
warped or not distorted. If the bin flange is warped, distorted or not level,
transfer bolt holes from the mounting flange at the time of installation. Shim,
with metal, as required before bolting mating flanges.

4. The mating flanges can also be welded, continuous internal and intermittent
or continuous external.

5. When bolting the mating flange, it is good practice t use a sealant such as
Permatex, Silastic or similar material between the flanges to prevent leakage
of fine particle size products. A thin, approximately 1/8Åh gasket of resilient
material may be used in place of a sealant. Sealant by others.

6. After installing the completely assembled Bin Activator and tightening all
bolts, run the unit empty for approximately ten minutes. Then recheck the
suspension arm bolts, vibrating mounting bolts and sleeve clamps for
tightness. Suspension arm bolts are Grade 5 and must be torqued to 466
foot pounds; vibrator mounting bolts as follows:

3 / 8Åh BOLT.....GRADE 5 ........................35 FOOT POUNDS

1 / 2Åh BOLT.....GRADE 5 ......................125 FOOT POUNDS

5 / 8Åh BOLT.....GRADE 5 ......................160 FOOT POUNDS

3 / 4Åh BOLT.....GRADE 8 ......................310 FOOT POUNDS

7 / 8Åh BOLT.....GRADE 8 ......................473 FOOT POUNDS

1Åh BOLT...........GRADE 8 ......................540 FOOT POUNDS

7. Metalfab 10 foot and 12 foot diameter Bin Activators and special units are
shipped unassembled, in some cases the mounting flange is split in half for
shipping purposes.
