Accessing the Energy Recovery Wheel
Disconnect power to the ERV
e
. Open door labeled
“Energy Wheel Cassette Access”.
Unplug the wheel drive motor.
Pull the wheel cassette halfway out.
Energy Recovery Wheel Maintenance
Annual inspection of the energy recovery wheel is
recommended. Units ventilating smoking lounges
and other non-clean air spaces should have energy
recovery wheel inspections more often based upon
need. Inspections for smoke ventilation applications
are recommended bimonthly to quarterly until a
regular schedule can be established.
Removing the Energy Recovery Wheel Segments
(stainless steel rim)
Steel retainers are located on the inside of the wheel
rim. Push the retainer towards the center of the
wheel, then lift up and away to release segments.

Important!
Place retainers back in the original
position before rotating the energy recovery wheel,
otherwise damage to retainer will occur.
Cleaning the Energy Recovery Wheel
If the wheel appears excessively dirty, it should be
cleaned to ensure maximum operating efficiency.
Only excessive buildup of foreign material needs to
be removed. Discoloration and staining of energy
recovery wheel does not affect its performance.
Thoroughly spray wheel matrix with household
cleaner such as Fantastik® or equivalent. Gently rinse
with warm water and using a soft brush remove any
heavier accumulation. A detergent/water solution can
also be used. Avoid aggressive organic solvents, such
as acetone. The energy recovery wheel segments
can be soaked in the above solution overnight for
stubborn dirt or accumulation.
After cleaning is complete, shake the excess water
from the wheel or segments. Dry wheel or segments
before placing them back into the cassette. Place
wheel or segments back into cassette by reversing
removal procedures.
CAUTION
Do not clean energy recovery wheel segments with
water in excess of 140ºF (60ºC).
Do not dry energy recovery wheel segments in air in
excess of 140ºF (60ºC).
The use of a pressure washer to clean segments is
not recommended
. Damage could result.
Energy Recovery Wheel Belt
Inspect belts each time
filters are replaced. Belts
that look chewed up
or are leaving belt dust
near the motor pulley
may indicate a problem
with the wheel. Be sure
to inspect wheel for
smooth and unrestricted
rotation. If a belt requires
replacement, contact
the local Greenheck
representative. Instructions
for replacement will ship with the new belt.
Energy Recovery Wheel Bearing
In the unlikely event that
a wheel bearing fails,
the bearing is behind
a removable plate on
the wheel support
beam. Contact the local
Greenheck representative
for detailed instructions
on how to replace the
bearing.
