1. Check all electrical connections for tightness
and contact.
2. Check for and remove all loose items in or near
the inlet and outlet of the unit.
3. Check that all remote controls are wired into
the control system, and all service switches are
in the OFF position.
4. Check that all optional accessories are installed
properly and secured.
5. Check that all filters are properly installed and
filter access doors are closed and latched.
6. Check that hopper discharge is open and the
storage container is sealed, if equipped.
7. Fill P-trap if equipped, or close faucet valve on
drain collection container if used.
8. Turn power ON at source.
9. Turn the blower motor ON then OFF to check
for proper rotation by referencing the rotation
arrow located on the motor’s mounting plate.
To reverse rotation, three-phase power supply:
Turn electrical power OFF at source, properly
lock-out power, and switch any two leads on
the output-side of the blower motor starter.

adjusting the volume control damper on the
blower discharge, if equipped.
Note: Excess airflow can shorten filter life,
cause electrical system failure, and blower
motor failure.
Service Information
Operational Checklist
1. Monitor overall performance of the collector.
2. Monitor exhaust. Exhaust should remain
visually clean throughout filter life. If leaks are
visible, check the filters for positive gasket seals.
3. Monitor hopper drainage. If slow or stopped,
check hopper for obstructions and clean as
necessary.
4. Check that the P-trap is full. Refill if low or dry.
5. Monitor pressure drop across the primary filter
and afterfilter (if equipped) using the
appropriate differential pressure gauge. See
Filter Cleaning and Replacement section.
6. For a typical installation, Donaldson
recommends filter replacement when the gauge
indicator needle is half way into the red zone.
See Filter Cleaning and Replacement section.
Note: Do not attempt to clean or wash the
primary filter. Replace only.
Note: Do not operate the unit without the first-
stage or primary filter in place.
Significant reduction in final filter life can
result.
