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.

Energy Wheel Cleaning

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, 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.
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.

Cleaning the Energy Wheel Motor

WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could
result in death or serious injury. Disconnect all electric
power, including remote disconnects before servicing.
Follow proper lockout/tagout procedures to ensure the
power can not be inadvertently energized.
Disconnect all electrical power, then use a vacuum cleaner
and brush to remove accumulated material from the
energy wheel motor. The use of spray aerosol cleaners is
not recommended. Examine the motor monthly for debris
accumulation.
Cleaning the 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 with potential
microbial growth or damage to the energy wheel could
occur.
5. Examine the module monthly for material build-up on
the wall surfaces.

Segment Removal and Replacement

Segment Removal - 900-15,000 wheel cfm

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
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 196).
5. Close any open segment retainers prior to rotating the
wheel. Failure to close any retainer may damage the
retainer, seals, or segments.
