INSTALLATION
Step 1 — Unpack and 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. The 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. Check to make sure that items such as the accessory
kit, thermostats, and the controller 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 jobsite.
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 the motor, fan wheels,
and coils. Failure to do so may have serious adverse effects on
unit operation. In case of motor and blower assembly, debris
deposits 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.
CAUTION
To avoid equipment damage, do not lift unit by the drain
pipe or refrigerant piping. Unit should be lifted using the
mounting brackets.

ESP - External Static Pressure
SP - Static Pressure
NOTE: (For Fig. 5 - Fig. 11):
1. There are multiple ESP settings available for each ducted unit.
2. All fan curves show examples of fan characteristics of the "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 setting.
4. ESP settings are listed in the first column of each table.
5. Select ESP setting according to the connected ductwork system.
6. Refer to the Wired Controller manual for details on static pressure settings.
