tors may be available in 115, 230 and 460 volt models. The damp-
er motor nameplate voltage should be verified prior to connection.
**A transformer may be provided in some installations to correct the
damper motor voltage to the specified voltage.

Maintenance

L 2
Establish a schedule for inspecting all parts of the fan. The
frequency of inspection depends on the operating conditions
and location of the fan.
Inspect fans exhausting corrosive or contaminated air within
the first month of operation. Fans exhausting contaminated air
(airborne abrasives) should be inspected every three months.
Regular inspections are recommended for fans exhausting
non-contaminated air.
It is recommended the following inspections be conduct-
ed twice per year:
• Inspect bolts and setscrews for tightness. Tighten as
necessary. Refer to Torque chart
• Inspect belt wear and alignment. Replace worn belts with
new belts and adjust alignment as needed. Refer to Belt and
Pulley Installation, page 5
• Bearings should be inspected as recommended in the
Conditions Chart, page 4
• Inspect for cleanliness. Clean exterior surfaces only.
Removing dust and grease on motor housing assures
proper motor cooling

Fan Bearings

The fan bearings are provided prelubricated. Any special-
ized lubrication instructions on fan labels supersedes informa-
tion provided herein. Bearing grease is a petroleum lubricant
in a lithium base conforming to an NLGI #2 consistency. If
user desires to utilize another type of lubricant, they take re-
sponsibility for flushing bearings and lines, and maintaining a
lubricant that is compatible with the installation.
