or replacement.Two additional access doors are provided
for service access into the filter / evaporator section.
Operation
Figure 104. IntelliPak II energy wheel section
WARNING
Toxic Hazards!
Do not use an energy wheel in an application where the
exhaust air is contaminated with harmful toxins or
biohazards. Failure to follow this instruction could
result in death or serious injury.
CAUTION
Motor Failure!
Do not install a variable frequency drive (VFD) to
control the energy wheel speed. This could result in
failure of the energy wheel motor.
WARNING
Confined Space Hazards!
Do not work in confined spaces where refrigerant or
other hazardous, toxic or flammable gas may be
leaking. Refrigerant or other gases could displace
available oxygen to breathe, causing possible
asphyxiation or other serious health risks. Some gases
may be flammable and or explosive. If a leak in such
spaces is detected, evacuate the area immediately and
contact the proper rescue or response authority. Failure
to take appropriate precautions or to react properly to
such potential hazards could result in death or serious
injury.
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.

ERW Startup
1. Turn the energy wheel clockwise (as viewed from the
pulley side) by hand to verify that the wheel turns
freely through a full rotation.
2. Confirm that all wheel segments are fully engaged inthe wheel frame and that the segment retainers are
completely fastened. See Figure106, p. 156.
3. Manually rotate the energy wheel clockwise through several
 rotations to confirm the seal adjustment and
proper belt tracking on the wheel rim. Correct belt
tracking is approximately midway between the seal
plate and the outer edge of the rim.
Note: The
 drive belt is a urethane stretch belt designed to
provide constant tension throughout the life of the
belt. No periodic adjustment is required. 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.
4. If the wheel has difficulty starting, turn off the power and
 inspect the wheel for excessive interference
between the wheel surface and the four diameter
seals.To correct interference, loosen the diameter seal
adjusting screws and back the diameter seals away
from the surface of the wheel. Apply power to confirm
free wheel rotation. Re-adjust and tighten the seals
according to instructions in the “Service and Repair”
section.
Damper Actuators
Stroke the actuators to observe full open and full closure
of the dampers.
Routine Maintenance
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, removed the wheel segments and follow these
steps:
1. Wash the segments or the wheel in a five-percent solution of non-acid-base coil cleaner (part no.
WARNING
Rotating Components!
During installation, testing, servicing and
troubleshooting of this product it may be necessary to
work with live and exposed rotating components. Have
a qualified or licensed service individual who has been
properly trained in handling exposed rotating
components, perform these tasks. Failure to follow all
safety precautions could result in rotating components
cutting and slashing technician which could result in
death or serious injury.
WARNING
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. Failure to disconnect power
before servicing could result in rotating components
cutting and slashing technician which could result in
death or serious injury.

CHM00021 at your local Trane parts center) or in an
alkaline detergent and warm water.
2. Soak the segments in the solution until grease, oil, and
tar deposits are loosened.
3. Before removing the cleaner, rapidly run your fingers across
 the surface of segments to separate polymer
strips for better cleaning action.
4. Rinse the dirty solution from the segments and remove the
 excess water before re-installing the segments in
the wheel.
Note: S
ome permanent staining of the desiccant may
remain but is not harmful to performance.
Cleaning Frequency
In reasonably clean office or school buildings, cleaning
with a coil cleaner 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 or more frequent
cleaning may be required to remove these contaminants
and restore performance. Periodic inspection of the wheel
should be done to determine the cleaning intervals.
High-maintenance applications may benefit from keeping
a spare set of clean segments on hand. This allows for
rapid change-out of clean segments with minimal
downtime. The dirty segments can then be cleaned at a
convenient time.
Segment Removal
Wheel segments for the low CFM energy recovery optionfor the 90, 105, and 120 ton units are secured to the wheel
frame by a segment retainer that pivots on the wheel rim
and is held in place by a segment retaining catch. All other
units have larger sized wheels and have inner and satellite
segments.The satellite segments are secured to the wheel
frame by a segment retainer in the same fashion as the
outer segments for the above mentioned smaller low CFM
recovery wheels. The inner segments are secured to the
wheel center hub with a screw.
Outer and Satellite Segment Removal
Procedure:
1. Disconnect all electrical power.
2. Secure wheel from rotation.
3. Pry the segment retainer latch out from the catch. See Figure 10 6. For the first or for an individual segment
removal, it will be necessary to do so on both sides of
the
 segment.
4. Remove the forked segment retainer(s). See Figure 10 6. Again, for the first or for an individual
segment removal, it will be necessary to do so on both
sides
 of the segment.
5. Remove the segment from the wheel frame. It may be necessary
 to gently pry the segment out of the wheel
with a screwdriver.
6. Pull the segment up and out of the wheel frame.
7. Close any open segment retainer prior to rotating the wheel.
 Failure to close the retainer may damage the
retainer, seals, or segments.
8. Rotate the wheel and continue this procedure to remo
 ve all segments. See Figure10 7, p .156.

periodic adjustment is required. 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.
1. Disconnect all electrical power.
2. Confirm the model number on the belt replacement kit
matches the model number on the label by the motor
pulley. Remove all remnants of the old belt.
3. Uncoil the belt as necessary. The belt must not twist when
 being feed around the wheel rim.
4. At a location near the motor pulley, tape the hook end of
 the belt to the wheel rim, see Figure110, p.159and
Figure 10 7, p .156.The tape should cover the hook and
belt.
5. Manually rotate the wheel clockwise while feeding the belt
 onto the wheel rim, taking care that the belt does
not twist.
Note: If
for any reason the belt were to become flipped or
twisted 90° in either direction, belt failure will be
imminent.
6. Upon feeding the belt completely through, remove the tape
 and join the link with the belt positioned around
the wheel rim, see Figure110, p.159. Keep light
tension on the belt, as a slack belt may be prone to
twist.
7. Manually rotate the wheel clockwise until the linked belt
 ends are approximately 180° from the motor
pulley location.
8. Insert the right angle belt retainer from the replacement
 kit at the pulley location. Place it between
the segment retainer latch pivot point and the wheel
spoke, see Figure111 , p .160(left of the spoke).
Important: T
 o avoid release of the segment latch do not
insert retainer on the other side of spoke. 9. Manually rotate the wheel counter-clockwise to
position
 the belt retainer clip close to the center beam
and diameter seals.
10. In a section between the retainer clip and the motor pulley
 , remove the belt from the wheel rim and then
place it over the pulley.
11. Manually rotate the wheel clockwise until the belt is fully
 stretched around the wheel rim and motor pulley.
12. Remove the belt retainer clip and manually rotate the wheel
 clockwise at least two full rotations while
verifying the belt is not twisted on the wheel rim or as
it enters the pulley(s).
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. Do not open the service access
doors while the unit is operating. Failure to disconnect
power before servicing could result in death or serious
injury.
CAUTION
Added Support Required!
Before laying across the energy wheel, place a rigid
board across the span of the energy wheel cassette.
Failure to do so could result in personal injury and/or
damage to the energy wheel.

Note:Pile seal brackets are fixed with a single screw to
the cassette frame near the ends of the wheel
bearing beam. Because the height of the belt link is
slightly higher than that of the urethane belt, a rare
interference may occur when it passes the seal
bracket. If this occurs, remove the interfering
bracket(s). No measurable change of performance
will occur.
Seal Adjustment
1. Disconnect all electrical power.
2. Loosen the diameter seal adjustment screws and back
the seals away from the wheel surface, see Figure11 2.
3. Rotate the wheel clockwise until two opposing spokes are
 hidden behind the bearing support beam.
4. Using a folded piece of paper as a feeler gauge,position the paper between the wheel surface and the
diameter seals.
5. Adjust the seals toward the wheel surface until slight friction
 on the paper feeler gauge is felt when the
gauge is moved along the length of the spoke.
6. Check the seal adjustment through a full rotation of the wheel.
 Re-tighten the adjusting screws and recheck the
clearance with the paper-feeler gauge.
Drive Motor and Pulley Replacement
1. Disconnect all electrical power.
2. Remove the belt from the pulley and position it temporarily
 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 earlier
 in this procedure.
