Refer to Table 2 for unit weights and to Figure 1 for approximate
center of gravity.
Filters should be checked monthly especially since this unit
may be used for both heating and cooling.
CLEARANCES
CONDENSATE DRAIN
All units require certain clearances for proper operation and
service. Refer to Figure 6 for the clearances required for
combustion, construction, servicing and proper unit operation.
A condensate trap is required to be installed in the condensate
drain. The plumbing must conform to local codes. Use a sealing
compound on male pipe threads. Install the condensate drain
line (3⁄4“ NPTF) to spill into an open drain.
WARNING: Do not permit overhanging structures or shrubs to
obstruct the condenser air discharge outlet.
DUCT WORK
These units are adaptable to downflow use as well as rear
supply and return air duct openings. To convert to downflow,
use the following steps:
1. Remove the duct covers found in the bottom return and
supply air duct openings. There are four (4) screws securing
each duct cover (save these screws to use later).
2. Install the duct covers, removed in step one, to the rear
supply and return air duct openings. Secure with the four
(4) screws used in step one.
3. Seal the duct covers with silicone caulking.
Downflow units must have an L-shaped supply duct without any
outlets or registers located directly below the supply outlet of
the unit.
Duct work should be designed and sized according to the
methods of the Air Conditioning Contractors of America
(ACCA), as set forth in their Manual D.
A closed return duct system shall be used. This shall not
preclude use of economizers or ventilation air intake. Flexible
joints may be used in the supply and return duct work to
minimize the transmission of noise.
CAUTION: When fastening duct work to the side duct flanges
on the unit, insert the screws through the duct
flanges only. DO NOT insert the screws through the
casing. Outdoor duct work must be insulated and
waterproofed.
NOTE: Be sure to note supply and return openings.
Refer to Figure 6 for information concerning rear and bottom
supply and return air duct openings.
FILTERS
Single phase units are shipped without a filter and is the
responsibility of the installer to secure a filter in the return air
ductwork or install a Filter/Frame Kit (1FF0114).
A filter rack and a filters are standard on three phase units.
Filters must always be used and must be kept clean. When
filters become dirt laden, insufficient air will be delivered by the
blower, decreasing your units efficiency and increasing operating costs and wear-and-tear on the unit and controls.
Unitary Products Group
SERVICE ACCESS
Access to all serviceable components is provided by the following removable panels:
• Blower service access
• Electrical/filter access
• Compressor service access
Refer to Figure 6 for location of these access panels and
minimum clearance.
THERMOSTAT
The room thermostat should be located on an inside wall
approximately 56" above the floor where it will not be subject
to drafts, sun exposure or heat from electrical fixtures or
appliances. Follow manufacturer’s instructions enclosed with
the thermostat for general installation procedure. Four, five or
six color coded insulated wires (minimum #18 AWG) should be
used to connect thermostat to unit. See Figure 3.
POWER AND CONTROL WIRING
Field wiring to the unit must conform to provisions of the current
N.E.C. ANSI/NFPA No. 70 or C.E.C. and/or local ordinances.
The unit must be electrically grounded in accordance with local
codes or, in their absence, with the N.E.C./C.E.C. Voltage
tolerances which must be maintained at the compressor terminals during starting and running conditions are indicated on the
unit Rating Plate and Table 1.
The wiring entering the cabinet must be provided with mechanical strain relief.
A fused or HACR breaker disconnect switch should be field
provided for the unit. If any of the wire supplied with the unit
must be replaced, replacement wire must be of the type shown
on the wiring diagram.
Electrical line must be sized properly to carry the load. Each
unit must be wired with a separate branch circuit fed directly
from the meter panel and properly fused.
Refer to Figure 2 for typical field wiring and to the appropriate
unit wiring diagram for control circuit and power wiring information.

SEQUENCE OF OPERATION FOR DEH MODELS
Units are shipped with compressor mountings factory-adjusted
and ready for operation.
CAUTION: Do Not loosen compressor mounting bolts.
Cooling
The following sequences of operation are based on using a
standard single-stage cooling thermostat.
WITH POWER TO UNIT AND THERMOSTAT IN COOLING
MODE.
1. If the fan switch on the thermostat is in the "ON" position,
the 24 volts at "G" will energize the "K1" relay on the fan
control board, close the "K1" relay contacts, and energize
the indoor blower motor. If the fan switch is in the "AUTO"
position, the blower will operate only when there is a call for
cooling by the thermostat.
2. On a call for cooling, the thermostat will send 24 volts to "Y"
on the fan control board. The 24 volt signal will energize
contactor "M1", and power will be supplied to the compressor and outdoor fan motor. If the fan switch on the thermostat is on the "AUTO" position, the thermostat will also send
a 24 volt signal to "G" on the fan control board and the indoor
blower will operate as indicated in step 1.
when the 24 volt "Y" signal is removed. If the fan switch on
the thermostat is in the "ON" position, the indoor blower will
continue to run. If the fan switch is in the "AUTO" position,
the 24 volt "G" signal will be removed, and after a 60 second
delay, the "K1" relay will open and de-energize the indoor
blower motor.

the 24 volts at "G" will energize the "K1" relay contacts, and
energize the indoor blower motor. If the fan switch on the
thermostat is in the "AUTO" position, the blower will operate
only when there is a call for heating by the thermostat.
2. On a call for heating, the thermostat will send 24 volts to
"W1" on the fan control board. The 24 volts signal will
energize relay "K2" on the fan control board, and the first
stage of electric heat will be energized.
3. When the heating demand is satisfied, the electric heat will
be de-energized when the 24 volt "W1" and "W2" signals
are removed. If the fan switch on the thermostat is in the
