Preliminary Start-Up Check
Instruct all personnel on safe use and maintenance
procedures.
Electrical work during
installation, service or
maintenance 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.
Check that hopper discharge is properly set
and functioning.
Turn compressed air supply OFF, bleed and
lock out lines before performing service or
maintenance work.
Check that the collector is clear and free of all
debris before starting.
Do not install in classified hazardous
atmospheres without an enclosure rated for
the application.
Optional fans over 600 lbs must be
independently supported.
5. Check that fan exhaust damper is set to the fully-
closed position.
6. Check and remove all loose items in or near the inlet
and outlet of the collector.
7. Check that all remote controls and solenoid
enclosures (if applicable) are properly wired and all
service switches are in the OFF position.

properly and secured.
9. Turn power ON at source.
10. Turn the compressed-air supply ON. Adjust pressure
regulator for 90-psig.

rotation through the back of the motor.
Check that the exhaust plenum is free of tools
or debris before checking blower/fan rotation.

Excess airflow can shorten filter
life, cause electrical system
failure and fan motor failure.
13. Turn powered hopper discharge devices ON.
1. Check all electrical connections for tightness and
contact.
2. Check for proper rotation as noted on the fan and/or
hopper discharge device housing.
To reverse rotation, single-phase power supply:
Follow manufacturer’s instructions on the motor’s
nameplate.
To reverse rotation, three-phase power supply:
Switch any two leads on the motor junction box.
Do not interchange a power lead
with the ground wire. Severe
personal injury and/or property damage may
result.
