Preliminary Start-Up
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 hopper discharge is open and the
storage container is sealed, if equipped. Excess
airflow to the fan will cause electrical failure.

7. Turn the compressed-air supply ON. Adjust
pressure regulator for 90 to 100-psig.
8. Turn the fan motor ON then OFF to check for
proper rotation by referencing the rotation arrow
located on the motors mounting plate.
To reverse rotation, single-phase power supply:
Follow manufacturers instructions on the
motors nameplate.
To reverse rotation, three-phase power supply:
Turn electrical power OFF at source and switch
any two leads on the output-side of the fan-
motor starter.
9. Adjust the fan for proper airflow by adjusting the
volume control damper on the fan discharge and
silencer, if equipped.
Note: Excess airflow can shorten filter life, cause
electrical system failure, and fan motor
failure.
