Routine Maintenance

WARNING
Hazardous Service Procedures!
The maintenance and troubleshooting procedures
recommended in this 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.
Unless specified otherwise, 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.

Maintenance Checklist

Frequency Maintenance
After 48 hours
For belt-drive fans, the belts have acquired their permanent set. Readjust but do not overtighten. See
of operation p. 55 for more information.
Every week
Observe unit weekly for any change in running condition and unusual noise.
• Clean or replace air filters if clogged or dirty; coat permanent filters with oil after cleaning; change bag filters when pressure drop is
1 in. w.g. See the "Filters" section on page 78 for more information.
Every month
• Belt-drive fans - relubricate fan bearings if necessary. See the "Fan Bearing Lubrication" section on page 77 for more information.
Belt-drive fans - check and adjust fan belt tension.See
• Belt-drive fans - check fan bearing grease line connections. Lines should be tight to the bearings.
• Check motor bracket torque. See
• Belt-drive fans - check bearing bolt torque and bearing setscrew torque. See
Every three to
• Belt-drive fans - align fan and motor sheaves. Tighten sheave set screws to the proper torque. See
six months p. 57 for more information.
• Inspect and clean drain pans. See the "Drain Pans" section on page 67 for more information.
• Tighten electrical connections.
• Inspect coils for dirt build-up. See the "Coils" section on page 64 for more information.
• Inspect the unit casing for corrosion. If damage is found, clean and repaint.
• Clean the fan wheels and shaft. See the "Fans" section on page 77 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.
Every year
• Inspect wiring for damage.
• Rotate the fan wheel and check for obstructions. The wheel should not rub. Adjust the center if necessary.
• Lubricate motor bearings in accordance with motor manufacturer's recommendations (see the "Motor Bearing Lubrication" section on
page 78 for more information).
• Check condition of gasketing and insulation around unit, door and dampers.
• Examine flex connections for cracks or leaks. Repair or replace damaged material.

Rotating Components!
The following procedure involves working with
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 rotor to
ensure rotor cannot freewheel. Failure to secure rotor
or disconnect power before servicing could result in
rotating components cutting and slashing technician
which could result in death or serious injury.
