Instruct all personnel on safe use and maintenance
procedures.
Use proper equipment and adopt
all safety precautions needed for
servicing equipment.
Use appropriate access equipment and
procedures. Note the standard collector is not
equipped with access platforms unless noted on
the specification drawings.
Electrical service or maintenance work must be
performed by a qualified electrician and comply
with all applicable national and local codes.
Turn power off and lock out electrical
power sources before performing service or
maintenance work.
Do not install in classified hazardous
atmospheres without an enclosure rated for the
application.
Maintenance Information
Turn positive displacement pump OFF and bleed lines and
tank before performing service or maintenance work.
Operational Checklist
1. Monitor the physical condition of the collector and repair or
replace any damaged components.
Routine inspections will minimize downtime and maintain
optimum system performance. This is particularly
important on continuous-duty applications.
Periodically check the positive displacement pump
components and replace filters as required to maintain
blower pressure rating. Check rotation of cleaning arms.
2. Monitor pressure drop across filters.
Abnormal changes in pressure drop may indicate a
change in operating conditions and possibly a fault to be
corrected.
4. Monitor exhaust.
5. Monitor dust disposal.
Weekly
1. Check that pressure drop is within normal operational
range (from 1 to 6 "wg).
2. Check for proper air pressure at reservoir (8 psi for 570-
608 collectors and 9 psi for all larger collectors).
3. Check for proper lubricant level in positive-displacement
blower.
Quarterly
1. Check condition of the clean-air plenum. If dust
accumulation is present, check filter bags for wear, tears
or loose seals. Replace as necessary.
2. On high inlet collectors, check the condition of the
removable baffle weld assembly by removing the side
access cover on the baffle housing. Replace significantly
worn baffle assemblies to prevent damage to the filter
tubes and housing section.
3. Check solenoid and diaphragm valve operation.
4. Check door seals and replace as necessary.
5. Check cleaning arm drive chain and positive-
displacement blower belt tension.
6. Check positive-displacement blower and gear reducer oil
levels. Add oil through breather mounting holes or other
oil fill locations. Reference the blower owner’s manual for
proper lubricant.
0°F-32°F - use ISO 68 lubricant
32°F-90°F - use ISO 100 lubricant
90°F-120°F - use ISO 150 lubricant
7. Inspect explosion vents, if applicable, for signs of wear or
cracks.
8. Check the rotating arm manifold drive gear reducer oil
level. Add oil through breather mounting holes or other
oil fill locations. The gear reducer is filled with synthetic
oil. See reducer manual for recommended lubrication
type and quantity. When checking or replacing the oil,
make sure to check both housings of the double reduction
reducer. Each housing has its own vent, fill and drain
plug.
