Routine Maintenance
Cleaning the Motor
WARNING
Hazardous Voltage!
Disconnect all electric power,
including remote disconnects before
servicing. Follow proper lockout/
tagout procedures to ensure the
power can not be inadvertently
energized. Failure to disconnect
power before servicing could result
in death or serious injury.
Disconnect all electrical power, then
use a vacuum cleaner and brush to
remove accumulated material from
the CDQ wheel motor. The use of
spray aerosol cleaners is not
recommended. Examine the motor
monthly for debris accumulation.
Cleaning the CDQ
Module
1. Disconnect all electrical power.
2. Use a vacuum cleaner to remove
dust and debris from the module
surfaces.
3. If needed, use a detergent
solution to remove grease, oil, or
other stubborn deposits from
module surfaces. Follow the
manufacturer's instructions
regarding use of the product.
4. Rinse any cleaning product
thoroughly from the module
walls. The use of a water stream
from a garden hose or high
pressure washer is not
recommended. Saturation of the
wall panel insulation could result
in potential microbial growth.
5. Examine the module monthly for
material build-up on the wall
surfaces.
Bearing and Motor
Lubrication
The wheel gear motor bearings are
pre-lubricated at the manufacturer
and do not require re-lubrication.
Wheels smaller than 8500 cfm,
66- inches in diameter, have a
permanently sealed inboard bearing
and need no maintenance. Larger
wheels come equipped with a
external flanged bearing that should
be greased annually.
Drive Belt Tension
The drive belt is a link stretch belt
designed to provide tension
throughout the life of the belt.
Inspect the belt annually for proper
tracking and tension. A properly
tensioned belt will turn the wheel
immediately, with no visible
slippage, when power is applied. If
belt needs tensioning, see "Drive
Belt Adjustment/Replacement" on
page 16.
