ACCESSORIES
RETURN AIR GRILLE - This decorative, expanded metal grille
will enhance the appearance of any unit that has no return air
ductwork and is especially recommended for units located
within the conditioned space.
SUPPLY AIR PLENUM - This decorative, horizontal discharge
plenum will enhance the appearance and performance of any
unit that does not have supply air ductwork. It has the same
durable finish as the evaporator blower, is fully insulated, is
shipped ready for mounting on horizontal or vertical units and
has grilles which may be adjusted to meet the throw and spread
requirements of the conditioned space.
BASE SECTION - The base section can be used to elevate
units off the floor. If desired, outdoor air may be introduced thru
these sections by cutting an access opening to accommodate
the outdoor air duct connection. The base has a durable finish
to match the evaporator blower unit. It may have to be insulated
for certain applications.
SUSPENSION PACKAGE - This accessory can be used to
suspend horizontal units from above without interfering with
access to the unit. It can also be used for elevating a floor-
mounted unit (either horizontal or vertical) to provide additional
height for the installation of a trap at the condensate drain
connection. A suspension package can be used with vibration
isolators.
HOT WATER COIL - A drainable water coil is available for field
installation between the blower and the coil modules of both
horizontal and vertical units. Since their casings match the
dimensions and the finish of the basic units, they become an
integral part of the unit after installation. The coil slides out of its
casing for easy installation. The coil has copper tubes that have
been mechanically expanded into aluminum fins. Both headers
are located on the same end of the coil. Each coil is leak-tested
at 325 psig under water and dried before their connections are
capped for storage and shipping.
STEAM COIL - A steam coil is available for field installation
between the blower and coil modules of both horizontal and
vertical units. Since their casings match the dimensions and
the finish of the basic units, they become an integral part of the
unit after installation. The coil slides out of its casing for easy
installation and is pitched in its casing to facilitate condensate
drainage. The coil has copper tubes that have been
mechanically expanded into aluminum fins. Both headers are
located on the same end of the coil. Each coil is leak-tested at
325 psig and dried before their connections are capped for
storage and shipping.
BLOWER MOTORS - Different HP motors are available to
meet almost any air delivery requirement. All motors are UL
approved, have inherent protection, permanently lubricated
ball bearings and get field-mounted within the insulated cabinet
of the unit to minimize the transmission of sound to the
surrounding space.
Power wiring for the blower motor is
field supplied.
DRIVE PACKAGES - Different size pulleys and belts are
available to provide a blower RPM range to meet almost any air
delivery requirement. Variable pitch motor pulleys can be
adjusted to provide the proper blower RPM. All drive packages
are rated at least 25% above the nominal HP rating of the
blower motor. Two-groove pulleys and two belts are provided
on every drive package rated at 5 HP.
