Routine Maintenance
The following checklist is provided as an abbreviated guide to periodic maintenance. Detailed
procedural information is given after this checklist.
WARNING
Hazardous Service Procedures!
The maintenance and troubleshooting procedures recommended in this section of the manual
could result in exposure to electrical, mechanical or other potential safety hazards. Always refer
to the safety warnings provided throughout this manual concerning these procedures. When
possible, disconnect all electrical power including remote disconnect and discharge all energy
storing devices such as capacitors before servicing. Follow proper lockout/tagout procedures to
ensure the power can not be inadvertently energized. When necessary to work with live
electrical components, have a qualified licensed electrician or other individual who has been
trained in handling live electrical components perform these tasks. Failure to follow all of the
recommended safety warnings provided, could result in death or serious injury.
WARNING
Rotating Components!
Disconnect all electric power, including remote disconnects before servicing. Follow proper
lockout/ tagout procedures to ensure the power can not be inadvertently energized. Secure
drive sheaves to ensure rotor cannot freewheel. Failure to secure drive sheaves or disconnect
power before servicing could result in death or serious injury.

Frequency Maintenance
After 48 hours
of operation
Belts have acquired their permanent set. Readjust but do not overtighten. See “Tension the Fan Belt” on page 78 for more
information.
Every week
Observe unit weekly for any change in running condition and unusual noise.
Every month
• Clean or replace air filters if clogged or dirty; coat permanent filters with oil after cleaning; and, change bag filters when
pressure drop is 1 in. wg. See “Air Filters” on page 86 for more information.
• Relubricate fan bearings if necessary. See “Fan Bearing Lubrication” on page 89 for more information.
• Check and adjust fan belt tension.
Every three to
six months
• Check fan bearing grease line connections. Lines should be tight to the bearings.
• Check bearing and motor bracket bolt torque and bearing setscrew torque.
• Align fan and motor sheaves. Tighten sheave set screws to the proper torque. See “Align Fan and Motor Sheaves” on
page 80 for more information.
• Inspect and clean drain pans. See the “Drain Pans” section on page 87 for more information.
• Tighten electrical connections.
• Inspect coils for dirt build-up. See “Coils” on page 91 for more information.
Every year
• Inspect the unit casing for corrosion. If damage is found, clean and repaint the surface with a rust-resistant primer.
• Clean the fan wheels and fan shaft. See “Fans” on page 88 for more information.
• Inspect and clean drain pans.
• Check damper linkages, set screws, and blade adjustment. Clean, but do not lubricate, the nylon damper rod bushings.
• Clean damper operators.
• Inspect electrical components and insulation.
• Inspect wiring for damage.
• Rotate the fan wheel and check for obstructions in the fan housing. The wheel should not rub on the fan housing. Adjust
the center if necessary and tighten wheel set screws to the proper torque.
• Lubricate motor bearings in accordance with motor manufacturer’s recommendations (see the “Motor Bearing Lubrication”
section on page 90 for more information). This may only need to be done every 2 to 3 years.
• Check condition of gasketing and insulation around unit, door and dampers.
• Examine flex connections for cracks or leaks. Repair or replace damaged material.
