DESCRIPTION
This completely assembled unit includes a well-insulated
cabinet, a DX coil with copper tubes and aluminum fins, an
expansion valve, a distributor, throwaway filters, a centrifugal
blower,ablower motor,an adjustablebeltdrive, ablowermotor
contactorand asmallholding chargeofrefrigerant-22. Theunit
ismanufacturedunderISO9002QualitySystemCertification.
The unit is shipped in the vertical position ready for field
installation. It can be installed for horizontal operation by
reversing the position of the solid bottom panel with the return
air duct flange on the front on the unit.
ACCESSORIES - FIELD INSTALLED
SUPPLYAIR PLENUM - A fully insulated plenum is available
forfree standingunits locatedwithin the conditionedspace. Itis
shipped knocked down for easy field assembly, is finished to
match the exterior of the basic unit, and has double deflection
grilles that can be adjusted to vary the throw, spread and drop
of the supply air.
RETURN AIR GRILLE - An expanded metal grille is available
forfree standingunits locatedwithin the conditionedspace. Itis
finishedtomatchtheexteriorofthebasicunitandisshipped in
one piece for easy installation.
BASE- Abaseisavailableto raisevertical unitsabovethefloor.
Outdoor air may be introduced through the base by cutting an
access opening to accommodate the outdoor air duct
connection. The base is finished to match the exterior of the
basic unit. It may have to be insulated in the field for certain
applications.
THREE-PHASE ELECTRIC HEATERS - Electric heaters are
available in four capacities to provide maximum flexibility. Both
the air conditioning unit and the heater can be selected to
precisely match the cooling and heating requirements of the
conditioned space. These heaters are designed for easy fieldinstallationover thesupplyair opening ofthe unit. Every heater
isfully protectedagainstexcessive currentandtemperature by
fuses and two high limit thermostats.
Units with electric heat require only one power supply for both
the heating elements and the supply air blower motor. The
power wiring can be protected by either dual element/time
delay fuses or an inverse time circuit breaker.
HOTWATERCOIL- Thisdrainable coilhas tworows of13mm (
1
in.) copper tubes, eight aluminum fins per 25mm (1 in.), a
2
casingthat isfinished tomatchthe exteriorof the basicunit, but
nowater control valve.Thecoil slides outof the casing foreasy
fieldinstallation.It shouldbe mountedbetween theunitcoiland
blower section.
STEAMCOIL -The non-freeze coil has onerowof 25mm (1in.)
copper tubes, a 16mm (
(1 in.) tube to distribute the steam evenly across the entire
length of the coil, eight aluminum fins per 25mm (1 in.), a
casing finished to match the exterior of the basic unit, but no
steam control valve. The coil slides out of the casing for easy
field installation and is pitched in the casing to facilitate
condensate drainage. It should be mounted between the unit
coil and blower sections.
SUSPENSION KIT - Suspension kit 1HH0451 is available for
units installed horizontally. The accessory includes two
channel iron supports and the hardware to secure them to the
topoftheunit.Thehangerrodsmustbesuppliedbythefield.
THERMOSTATS - Wall-mounted thermostats and subbases
(24volt) with system and fan switches are available to control
the operation of these split system air conditioners.

Thisunit has two distinct modules, a blower module
and a coil module. The unit is always shipped in the
vertical position with a vertical air discharge as
shown in illustration (a). The blower module can be
repositionedinthefield asshown inillustration (b)or
(c) for maximum flexibility.
