To minimize air that bypasses the wheel the perimeter
seals should be adjusted such that air gaps are not visible
around the wheel. Do not over compress the seal against
the perimeter as this may cause the wheel not to turn or
overload the motor. To minimize air the leaks from one
side to the next the diameter seals should be adjusted to
come in full contact with the wheel face.

minimize leaks
CDQ Drive Motor and Pulley Replacement
1. Disconnect all electrical power.
2. Remove the belt from the pulley and temporarily
position it around the wheel rim.
3. Measure and record the distance from the inner edge
of the pulley to the mounting wall.
4. Loosen the set screw in the wheel drive pulley using an
Allen wrench and remove the pulley from the motor
drive shaft.
5. While supporting the weight of the drive motor in one
hand, loosen and remove the four mounting bolts.
6. Install a replacement motor with the hardware kit
supplied.
7. Install the pulley and adjust it to the distance recorded
in the previous step.
8. Tighten the set screw to the drive shaft.
9. Stretch the belt over the pulley and engage it in the
groove.

Energy Wheels

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.
NOTICE:
Equipment Damage!
Do not use acid based cleaners, aromatic solvents,
steam or temperatures in excess of 170°F to prevent
damage to internal components. Trane assumes no
responsibility for equipment damage caused by
cleaning solutions or steam.
NOTICE:
Reduced Airflow!
Accumulated dirt and debris may result in reduced
airflow and/or increased pressure drop across the
energy wheel. Increased pressure drop can result in
permanent damage to the energy wheel. Trane is not
responsible for equipment-only-damage caused by
debris.

Cleaning the Energy Wheel

Disconnect all electrical power, then use a vacuum or
brush to remove accumulated material from the face of the
wheel. Examine the energy wheel monthly for material
build-up on the wheel.
If more aggressive cleaning is needed, consult
manufacturer's instructions.
Cleaning Frequency
In reasonably clean office or school buildings, cleaning
with a solution may not be required for several years. If the
energy wheel is exposed to air streams containing, for
example, high levels of occupant tobacco smoke, cooking
facility exhaust air, or oil-based aerosols found in machine
shop areas, annual cleaning may be required to remove
these contaminants and restore performance.
Energy Wheel Bearing and Motor
Lubrication
The wheel drive motor and wheel support shaft bearings
are permanently lubricated and no further lubrication is
necessary.
