INSTALLATION, OPERATION, & MAINTENANCE MANUAL

SECTION ONE — Receipt & Initial Installation, Cont’d.
Sales Representative should be notified immediately so
that proper action may be taken.
NOTE: Should any questions arise concerning warranty repairs, the
factory must be notified BEFORE any corrective action is taken.
Where local repairs or alterations can be accomplished,
the factory must be fully informed of the extent and
expected cost of those repairs before work is begun.
Where factory operations are required, the factory must
be contacted for authorization to return equipment and a
Return Authorization Number will be issued. Unauthorized
return shipments of equipment and shipments not marked
with an authorization number will be refused. In addition,
any claims for unauthorized expenses will not be accepted
by the manufacturer.
Handling and Installation
While all equipment is designed and fabricated with
sturdy materials, and may present a rugged appearance,
great care must be taken to assure that no force or
pressure be applied to the coil, piping or drain stub-
outs during handling. Also, depending on the options
and accessories, some units could contain delicate
components that may be damaged by improper handling.
Wherever possible, all units should be maintained in an
upright position, and handled by the chassis, plenum
sections, or as close as possible to the mounting-point
locations. In the case of a full cabinet unit, the unit must
obviously be handled by the exterior casing. This is
acceptable providing the unit is again maintained in an
upright position, and no force is applied that may damage
internal components or painted surfaces.
The equipment covered in this manual IS NOT suitable
for outdoor installations. The equipment should never be
stored or installed where it may be subjected to a hostile
environment such as rain, snow, or extreme temperatures.
Before, during, and after installation, special care must be
taken to prevent foreign material such as paint, plaster,
and drywall dust from being deposited in the drain pan or
on the motor or blower wheels. Failure to do so may have
serious adverse effects on unit operation, and in the case of
the motor and blower assembly, may result in immediate or
premature failure. All manufacturer’s warranties are void if
foreign material is allowed to be deposited in the drain pan
or on the motor or blower wheels of any unit. Some units
and/or job conditions may require some form of temporary
covering during construction.
Installation Instruction for Ceiling Hung Units
Anchoring the equipment in place is accomplished by
using the mounting points provided with 3/8” or 1/2”
all thread (not supplied with unit). See Figure 1 for
recommended all-thread diameter. The unit must be
positioned so that the drain pan is on a LEVEL PLANE.
Care must be taken to insure that the drain pan does not
slop away from the outlet connection. Horizontal open
coil unit models HHY or FHY may be mounted using the
neoprene grommets provided. Plenum-type unit models
HPY or CPY may be mounted using the four grommets in
the coil section, or the rear coil section grommets may be
removed to the plenum hanger brackets. Hi-performance
cabinet unit models HLY or HXY must be mounted using
the slotted hanger rails provided. (Grommets are not
furnished from the factory).
Other field-furnished mounting devices such as rubber-
in-shear or spring-type vibration isolators selected by the
contractor or engineer may be substituted for the factory
grommets, and should be used where factory grommets
are not provided.
It should be noted that unacceptable system operating
characteristics and/or performance may result from
improper or inadequate unit structural support. In addition
adequate clearance must be provided for service and
removal of the equipment and its accessory components.
