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.
WARNING
Keep Hands Away!
Always keep hands away from the
bearing support beam when
installing or removing segments.
Failure to do so could result in
serious injury.
CAUTION!
Cleaners And Solvents
Do not use acid based cleaners,
aromatic solvents, steam, or
temperatures in excess of 170°F.
Doing so may cause damage to the
wheel!
CAUTION!
Keep Wheel Clean
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 or
module.
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.

Routine
Maintenance
If more aggressive cleaning is
needed, segment removal may be
required.
1. Wash the segments or the wheel
in a five-percent solution of non-
acid-base coil cleaner (part no.
CHM00021 at your local Trane
parts center) or in a 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 the segments to
separate the polymer strips for
better cleaning actions.
4. Rinse the dirty solution from the
segments and remove excess
water before re-installing the
segments in the wheel. Note that
some permanent staining of the
desiccant may remain but is not
harmful to performance.
Cleaning Frequency
In reasonably clean office or school
buildings, cleaning with 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
cleaning may be required to remove
these contaminants and restore
performance.
High maintenance applications like
these 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/
Replacement
Segment Removal (for
wheel cfm 900-15,000)
For unit sizes 3 to 8, the energy wheel
module is equipped with only one
access panel and the entire energy
wheel cassette slides out through the
door for maintenance. For unit sizes
10 to 50, the energy wheel module is
equipped with four access doors and
the wheel segments are removable.
Wheel segments are secured to the
wheel frame by a segment retainer,
which pivots on the wheel rim and is
held in place by a segment retaining
catch.
1. Disconnect all electrical power.
2. Unlock the two segment retainer
brackets, one on each side of the
selected segment opening (see
Figure 9).
3. Remove the segment from the
wheel frame. It may be necessary
to gently pry the segment out of
the wheel with a screwdriver.
4. Pull the segment up and out of
the wheel frame (see Figure 10).
5. Close any open segment retainers
prior to rotating the wheel. Failure
to close any retainer may damage
the retainer, seals, or segments.
6. Slowly rotate the wheel by hand
180 degrees and repeat the
process to remove the second
segment.
7. Rotate the wheel 90 degrees by
hand and remove the third
segment.
