"MAX. ESP," "RATING ESP," and "MIN. ESP" settings;
these curves are shown for High (H), Medium (M), and
Low (S) speeds, as selected by the user at the controller.
3. All tables show air flows at “H-Speed” for each ESP set

INSTALLATION
Step 1 — Unpack the Inspect Units —
Units are
packaged for shipment to avoid damage during normal transit
and handling. It is the receiving party’s responsibility to inspect
the equipment upon arrival. Any obvious damage to the carton
and/or its contents should be reported on the bill of lading and a
claim should be filed with the transportation company and the
factory. Unit should always be stored in a dry place, and in the
proper orientation as marked on the carton.
After determining the condition of the carton exterior, carefully
remove each unit from the carton and inspect for hidden
damage. Make sure that items such as the accessory kit,
thermostats, controller, etc. are accounted for whether
packaged separately or shipped at a later date. Any hidden
damage should be recorded, a claim should be filed with the
transportation company, and the factory should be notified.
In the event a claim for shipping damage is filed, the unit,
shipping carton, and all packing must be retained for physical
inspection by the transportation company. All units should be
stored in the factory shipping carton with internal packaging in
place until installation.
PROTECTING UNITS FROM DAMAGE — Do not apply
force or pressure to the coil, piping, or drain stub-outs during
handling. All units should be handled by the chassis or as close
as possible to the unit mounting point locations.
The unit must always be properly supported. Temporary
supports used during installation or service must be adequate to
hold the unit securely. To maintain warranty, protect units
against hostile environments (such as rain, snow or extreme
temperature), theft, vandalism, and debris on job site.
Equipment covered in this manual is not suitable for outdoor
installations.
Do not allow foreign material to fall into drain pan. Prevent
dust and debris from being deposited on motor, fan wheels and
coils. Failure to do so may have serious adverse effects on unit
operation and in the case of motor and blower assembly, may
result in immediate or premature failure. Failure of any unit
caused by deposits of foreign material on the motor or blower
wheels will not be covered by the manufacturer’s warranty.
Some units and/or job conditions may require some form of
temporary covering during construction.
