Maintenance Information
Instruct all personnel on safe use and maintenance
procedures.
Use proper equipment and adopt
all safety precautions needed
for servicing equipment. 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.
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 compressed air components
and replace compressed air filters.
Drain moisture following the manufacturer’s
instructions. With the compressed air supply ON,
check the cleaning valves, solenoid valves, and
tubing for leaks. Replace as necessary.
2. Monitor pressure drop across filters.
Abnormal changes in pressure drop indicate a
change in operating conditions and possibly a fault
to be corrected. For example, prolonged lack of
compressed air will cause an excess build-up of dust
on the filters resulting in increased pressure drop.
Cleaning off-line with no flow usually restores the
filters to normal pressure drop.
3. Monitor exhaust.
4. Monitor hopper drainage. If slow or stopped, check
hopper for obstructions and clean as necessary.
5. Check that the P-Trap is full. Refill if low or dry.
6. If equipped with a HEPA or 95% DOP, monitor
pressure drop across after filter. Initial final filter
pressure drop is approximately 1-2”wg. Replace the
final filter when the gauge reads 3.5 to 4.0”wg. Do
not attempt to clean or wash the final filter. Replace
only.
Do not operate the unit without
the first- or primary-stage filter
in place. Significant reduction in final filter life
can result.
Filter Removal and Installation
Use proper safety and protective
equipment when removing
contaminants and filters.
Dirty filters may be heavier than they appear.
Use care when removing filters to avoid
personal injury.
First Stage Filter Cleaning and Installation
Remove the first stage filter through the lower access
door. Clean the first-stage screen by tapping it gently
over an appropriate waste container. If further cleaning
is required, wash in an appropriate wash tank. To clean
the first-stage filter, soak in an appropriate wash tank,
rinse, dry, and re-install.
High temperature, steam-
cleaning methods should not be
used with the polypropylene filters due to the
temperature limitations.
Do not operate the WSO mist collector without
the first-stage filter in place. Significant
reduction in primary filter life can result.
