Preliminary Start-Up Check
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 blower will cause electrical
failure.

proper rotation by referencing the rotation
arrow located on the motor’s mounting plate.
To reverse rotation, single-phase power supply:
Follow manufacturer’s instructions on the
motor’s 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.

manually shake the EZ Filter Pack.
