Accessing the Energy Recovery Wheel
Disconnect power to the ERVe. 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.

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.

IMPORTANT
Place retainers back in the original position before
rotating the energy recovery wheel, otherwise damage
to retainer will occur.
