RECEIVING AND HANDLING
The ERM is thoroughly inspected and test run at the factory. However, damage may occur during shipping
and handling. Upon delivery, inspect the unit for both obvious and hidden damage. If damage is found, record
all necessary information on the bill of lading and file a claim with the final carrier. In addition, ensure all
accessory items are present. Some accessory items are stored inside the unit during shipping.
SAFETY WARNING
Improper installation, adjustment, alteration, service or maintenance can cause property damage, injury or
death. Read this installation, operation, and maintenance manual thoroughly before installing or servicing this
equipment. Installation and service must be performed by a qualified installer, service agency, or the gas supplier.
SAVE THIS MANUAL
This manual is the property of the owner, and is required for future maintenance.
This manual should remain with each ERM unit when the job is complete.
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 Fantastic
™
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.
** DO NOT CLEAN ENERGY RECOVERY WHEEL SEGMENTS WITH WATER IN EXCESS OF 140°F
** DO NOT DRY ENERGY RECOVERY WHEEL SEGMENTS IN AIR IN EXCESS OF 140°F.
** THE USE OF A PRESSURE WASHER TO CLEAN SEGMENTS IS NOT RECOMMENDED. DAMAGE
COULD RESULT.

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.
ACCESSING ENERGY RECOVERY WHEEL
Disconnect power to the ERM unit. Remove access panel and UNPLUG the wheel drive motor. Pull the
cassette halfway out.
REMOVING THE ENERGY RECOVERY WHEEL SEGMENTS
Rotate the wheel by hand clockwise (as viewed from the pulley side of cassette) to check each
segment. Steel retainers are located on the inside of the wheel rim (see
diagram). Push the retainer toward center of wheel, the 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.

ROUTINE MAINTENANCE
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 BEARINGS
In the unlikely event that a wheel bearing fails, the bearing is
behind a removable plate on the wheel support beam (slide
cassette halfway out of cabinet to access). Contact the local
Greenheck representative for detailed instructions on how to
replace the bearing.
