PROBLEM
Motor/blower won’t start or won’t stay
running.
Dust emissions from clean air
discharge.
Insufficient airflow.
POSSIBLE CAUSES
Blower rotation is running in reverse.
No voltage to system.
Improper electrical wiring.
Starter overloads are tripped.
Hopper discharge open to
atmosphere.
Blower damper not properly adjusted.
Low system static pressure.
Filters not installed properly.
Filters are damaged.
Filter access doors not installed
properly.
Blower rotation is running in reverse.
Loose or open access.
Volumetric duct dampers or blower outlet
damper is not positioned properly.
An inlet(s) obstructed.
Filters plugged.
RECOMMENDED SOLUTIONS
Reverse blower rotation (refer to Section
5.1).
Check primary voltage to motor circuits for
proper voltage on all legs.
Check and correct internal motor wiring
for proper connections based on the incom-
ing line voltage at the motor junction box.
Check control voltage power (i.e. fuses, trans-
former, etc.).
Check for proper motor starter overload
rating against full load amps on motor name-
plate. Adjust or replace overloads as required.
Ensure drum is properly sealed against drum
lid package. Ensure drum lid package is prop-
erly installed (refer to Figure 13).
Check motor current draw and close
volumetric control damper or silencer damper
until amperage FLA is below full load rating
of motor.
Close dampers to increase static pressure or
install orifice plate in a branch duct.
Inspect and reinstall cartridge filters (refer to
Section 6), gasket end first.
Replace damaged filter(s) with new ProTura
®
Nanofilber cartridge filter(s).
Remove and reinstall QuickSeal filter access
door assembly (refer to Figure 17 and
Section 6).
Reverse blower rotation (refer to Section 5.1).
Remove QuickSeal filter access door assem-
bly, verify filters are properly installed (refer to
Section 6.1 and Figure 17), gasket end first.
Verify drum lid is installed properly (refer to
Figure 13).
Adjust dampers to allow for sufficient air vol-
ume (refer to Sections 5.1 and 5.2).
Inspect and clean all hoods and other machine
connections.
Refer to troubleshooting procedures for con-
tinual pressure drop.
