FOR DISTRIBUTION USE ONLY - NOT TO BE USED AT POINT OF RETAIL SALE
DESCRIPTION
These completely assembled units include a well-insulated cabinet, a
DX cooling coil with copper tubes and aluminum fins, expansion
valve(s), distributor(s), throwaway filters, a centrifugal blower, a blower
motor, an adjustable belt drive, a blower motor contactor and a small
holding charge of refrigerant-22.
The units are shipped in the vertical position ready for field installation.
They can be installed for horizontal operation by reversing the position
of the solid bottom panel with the return air duct flange on the front of
the unit.
ACCESSORIES—FIELD INSTALLED
SUPPLY AIR PLENUMS
These fully insulated plenums are available for free standing units
located within the conditioned space, are shipped knocked-down for
easy field assembly, are finished to match the exterior of the basic
unit, and have double deflection grills that can be adjusted to vary the
throw, spread and drop of the supply air.
RETURN AIR GRILLS
These expanded metal grills are available for free standing units
located within the conditioned space, are finished to match the exterior
of the basic unit and are shipped in one piece for easy installation.
BASES
Bases are available to raise vertical units above the floor. Outdoor air
may be introduced through these bases by cutting an access opening
to accommodate the outdoor air duct connection. These bases are fin-
ished to match the exterior of the basic unit. They may have to be insu-
lated in the field for certain applications.
THREE-PHASE ELECTRIC HEATERS
Electric heaters are available in several capacities to provide maxi-
mum 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 field
installation over the supply air opening of the unit. They have been
tested by and will be shipped with a CSA label. Every heater will be
fully protected against excessive current and temperature by fuses
and two high limit thermostats.
Units with electric heat will require only one power supply for both the
heating elements and the supply air blower motor, and the power wir-
ing can be protected by either dual element/time delay fuses or an
inverse time circuit breaker.

NOMENCLATURE
ACCESSORIES-FIELD INSTALLED (CONT.)
HOT WATER COILS
These drainable coils have 2 rows of 1/2" copper tubes, 12
aluminum fins per inch, a casing that is finished to match the
exterior of the basic unit, but no water control valve. The coils
slide out of their casings for easy field installation. They
should be mounted over the return air opening on 5, 7-1/2
and 10-ton units—between the unit coil and blower sections
on 15-ton units.
STEAM COILS
These non-freeze coils have 1 row of 1" copper tubes, a 5/8"
copper tube inside each 1" tube to distribute the steam evenly
across the entire length of the coil, 8 aluminum fins per inch,
a casing that is finished to match the exterior of the basic unit,
but no steam control valve. The coils slide out of their casings
for easy field installation and are pitched in their casings to
facilitate condensate drainage. They should be mounted over
the return air opening on 5, 7-1/2 and 10-ton units—between
the unit coil and blower sections on 15-ton units.
SUSPENSION KIT
Suspension kit 1HH0451 is available for 15-ton units installed
horizontally. The accessory includes two channel iron sup-
ports and the hardware to secure them to the top of the unit.
The hanger rods must be supplied by the field.
THERMOSTATS
Wall-mounted thermostats and subbases (24-volt) with sys-
tem and fan switches are available to control the operation of
these split system air conditioners.
APPLICATION FLEXIBILITY
MODELS 5, 7-1/2 & 10 TON
These units are built in a single cabinet with two condensate
drain pans. This allows the units to be installed in either the
vertical or horizontal position for maximum flexibility.
On vertical applications, the air velocity across the cooling
coil keeps the condensate from dripping off the finned sur-
face onto the filters.
On horizontal applications, the unit must be installed with the
condensate drain pan under the entire cooling coil.
• The Supply Air Plenum and the Return Air Grill accesso-
ries can be used on either arrangement.
• The Base accessory can only be used on the vertical
arrangement.
Units installed horizontally are designed for ceiling suspen-
sion. Four 3/8"-16 weld nuts are provided in the angle sup-
ports on the front of the unit (the side with the logo).
Knockouts are provided in the exterior panels for access to
these weld nuts. The hanger rods must be supplied in the
field.

These units have two distinct modules . . . a blower module
and a coil module. Although the unit is always shipped in the
vertical position with a vertical air discharge as shown in illus-
tration (a), the blower module can be repositioned in the field
as shown in illustrations (b) and (c) for maximum flexibility.
• The Supply Air Plenum, Return Air Grill and Base acces-
sories can be applied on arrangement (a).
• The Return Air Grill and Base accessories can be
applied on arrangement (b).
• The Supply Air Plenum, Return Air Grill and Suspension
accessories can be applied on arrangement (c).

1. Adjusting the vertical louvers will vary the throw, the spread and the drop.
2. Adjusting the horizontal louvers will only vary the drop.
3. The velocity of the air will be 125 ft./min. at the minimum distance and 80 ft./min. at the maximum distance.
4. The velocity of the conditioned air at the bottom of the drop will be 50 ft./min. Drafts will occur if the drop extends into the occupied
level of the conditioned space.

WITH ELECTRIC HEAT - Remove this 2-1/2” knockout from the
rear panel of the plenum. Route the power wiring conduit through
this opening and connect it to the field-supplied fitting on the elec-
tric heat accessory. Connect the power wiring to the fuse block in
the heater control box.
Install the control wiring per basic unit Installation Manual.
DO NOT route any field control wiring through the plenum.
WITHOUT ELECTRIC HEAT - Install the power and the control wiring
per basic unit Installation Manual. DO NOT route any wiring through
the plenum and DO NOT remove this knockout.
Electric Heaters are NOT CSA approved for installation
within a supply air plenum.
WITH ELECTRIC HEAT - Remove this 2-1/2” knockout and one of the 7/8”
knockouts from the rear panel of the plenum. Remove the 1-23/32” knockout
and one of the 7/8” knockouts from the top panel of the basic unit. Install a 1/
2” squeeze connector in both of the 7/8” openings.
Route the power wiring conduit through the 2-1/2” opening and connect it
to the field-supplied fitting on the electric heat accessory. Connect the
power wiring to the fuse block in the heater control box.
Route the control wires through the 7/8” openings and connect them to
the terminals on block TB1. Secure them with the 1/2” squeeze connec-
tors.
Electric Heaters are NOT CSA approved for installation
within a supply air plenum.
WITHOUT ELECTRIC HEAT - Remove both 7/8” knockouts from the rear
panel of the plenum and both 7/8” knockouts from the top panel of the
basic unit. Install a 1/2” squeeze connector in one of the plenum open-
ings and both of the unit openings. Install a 1/2” conduit fitting in the other
opening of the plenum.
Connect the power wiring conduit to the fitting on the plenum. Route the
power wiring through the conduit, one of the squeeze connectors on the
unit, and the field-supplied squeeze connector on the blower motor contac-
tor box. Connect the power wiring to the blower motor contactor.
Route the control wires through the remaining plenum and unit open-
ings and connect them to the terminals on block TB1. Secure them
with the 1/2” squeeze connectors.
