STORAGE

When a unit is not going to be in service for an extended amount of time, certain procedures should be
followed:

• Cover unit with tarp to protect from dirt and moisture (Note: do not use a black tarp as this will
promote condensation)

• Store unit in location which does not have vibration

If storage of unit is in a humid, dusty or corrosive atmosphere, rotate the fan and purge the bearings once a
month. Improper storage which results in damage to the unit or components will void the warranty.

ELECTRICAL CONNECTIONS

The electrical supply must be compatible with that shown on the wheel drive motor nameplate: voltage,
phase, and amperage capacity (see page 3 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 power the ERM whenever the 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 in. x 3/4 in. 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.

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 secure the brackets as
shown in Figure 1. These brackets are designed for 3/8 in. 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.
