WSO Mist Collector, WSO M

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.
2. Monitor pressure drop across filters using the
differential pressure gauge.
Abnormal changes in pressure drop may indicate a
change in operating conditions and possibly a fault
to be corrected.
4. Monitor exhaust.
5. Monitor hopper drainage. If slow or has stopped,
check hopper for obstructions and clean as
necessary.
6. For a typical installation, Donaldson recommends
filter installation when the gauge indicator needle
is half way into the red zone. See First Stage Filter
Cleaning and Installation.
Do not attempt to clean or wash
the primary filter. Replace only.
Do not operate the unit without the first stage
or primary filter in place. Significant reduction
in final filer 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.
Turn power off and lock out electrical
power sources before performing service or
maintenance work.
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.
Do not operate the WSO M mist
collector without the first-stage
filter in place. Significant reduction in primary
filter life can result.
High temperature, steam-
cleaning methods should not be
used with the polypropylene filters due to the
temperature limitations.
