INSTALLATION, OPERATION AND MAINTENANCE MANUAL
**WARNING**
DISCONNECT ALL ELECTRICAL POWER TO THE ERM PRIOR TO INSPECTION OR SERVICING.
FAILURE TO COMPLY WITH THIS SAFETY PRECAUTION COULD RESULT IN SERIOUS INJURY OR DEATH.

INSTALLATION

Greenheck Energy Recovery Modules (ERM) are thoroughly inspected
and test run at the factory, however damage may occur during handling
and shipping. Consequently, it is important to inspect the unit for visible
and concealed damage before beginning installation. Report any
damage to the shipper immediately. Turn the wheel by hand (clockwise
as viewed from the pulley side) to verify the wheel rotates freely. In
addition, assure all accessory items are present.

ELECTRICAL CONNECTIONS

The electrical supply must be compatible with that shown on the wheel
drive motor nameplate: voltage, phase, and amperage capacity (see
page 2 for specific requirements). Units are supplied with a receptacle
for the cassette plug and service box for wiring. Connect the ERM
wiring directly to blower wiring or to blower fan relay to assure power to
the ERM whenever fan is in operation. All wiring must be properly fused
and conform to local and national electrical codes.
DO NOT OPERATE THE ERM FOR ANY EXTENDED PERIOD WITHOUT
AIRFLOW ACROSS THE ENERGY WHEEL AS THE DRIVE MOTOR IS
COOLED BY THE AIRFLOW.

MOUNTING

The ERM is shipped with a mounting kit, which contains four hanging brackets, fasteners and a separate instruction sheet with
parts list. These brackets will support the ERM in either the vertical or horizontal position for design flexibility. A 3/8"x3/4" hex
head bolt is located at each corner of the ERM for attaching these brackets. To hang
the ERM:
Note: To reduce unit weight for handling purposes, the cassette may be removed from
the cabinet (reduces ERM-36 from 155 lbs. to 75 lbs., reduces ERM-52 from 280 lbs. to
110 lbs.).
1. To remove the cassette from the cabinet, remove the access panel and unplug the
wheel drive motor at the electrical receptacle in the cabinet.
2. Replace the access panel before mounting to insure squareness.
3. Remove the appropriate four bolts from the ERM and use to

designed for 3/8" threaded hanging rods.
4. To reinstall the cassette in the mounted ERM cabinet, align
the cassette sliders with the channels in the cabinet and slide
the cassette in place. Replace access panel when finished.
IMPORTANT: ERM MUST BE INSTALLED SUCH THAT THE
ENERGY WHEEL CASSETTE SLIDES IN AND OUT OF THE
CABINET PARALLEL TO THE FLOOR.
