A manual that details the operation of the pulse control is available under
separate cover.
Pre-Start Up
Turn the fan “ON” for a brief instant (JOG) and check rotation. Rotation must be clockwise
when viewed “OVER THE MOTOR” from the discharge side. If the rotation is correct start
motor.
Check to assure that air leaks do not exist at the seams of any field assembled cabinet
components such as Duct connections or the booth connections
Check the compressed air system for leaks. Confirm 80 PSI minimum air pressure and 90
maximum air pressure.
Assure the compression couplings of the pulse valves are tight.
Check each valve to assure each valve pulses as required.
Check each valve for leaks. It is normal for the bleed air port to release a burst of air at each
pulse.
Check adequacy of air supply by assuring no less than 40% drop in pressure during pulse.
Filter Installation
Should the filter be shipped loose from the collector they must be installed as follows prior to
start up?
Be sure the horizontal flange around the venturi is clean. With care not to damage filter
cartridge place gasket side down on flange. Rotate filter slightly to assure no binding and
proper location on the flange.
Most DIVERSITECH dust collectors use two filters, stacked vertically on each venturi. Position
second filter directly on top of first filter, gasket side down and centered vertically with lower
filter.
Place filter cap with gasket side down on top of the top filter cartridge and centered on
opening. Turn “T” handle, clockwise, down against filter cap so that the dimple penetrates the
threaded bore of the “T” handle. Continue to rotate “T” handle until gaskets are
approximately 30% compressed.
Start Up
New filters should be properly pre-conditioned before start up. Factory pre-conditioned filters
are available from DIVERSITECH. Filters not pre-conditioned can be conditioned in the field.
Please contact your DIVERSITECH Distributor for assistance.
Start system fan and confirm the designed air volume and actual air volume are within 10%. If
the air volume is more than the designed volume adjustments should be made to reduce the
volume to the designed volume.
