CLEARANCES
FILTERS
All units require certain clearances for proper operation and
service. Refer to Figure 3 for the clearances required for com
bustion, construction, servicing and proper unit operation.
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 sup
ply 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 secur
ing each duct cover (save these screws to use later).
2. Install the duct covers, removed in step one, tothe rear sup
ply 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 throughthe 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 3 for information concerning rear and bottom
supply and return air duct openings.
Single phaseunits are shipped without a filter and isthe responsi
bility 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 fil
ters become dirt laden, insufficient air will be delivered by the
blower, decreasing your units efficiency and increasing operat
ing costs and wear-and-tear on the unit and controls.
Filters should be checked monthly especially since this unit
may be used for both heating and cooling.
-
CONDENSATE DRAIN
A condensate trap is required to be installed in the condensate
drain. The plumbing must conform to local codes. Use a seal
ing compound on male pipe threads. Install the condensate
drain line (
3
“ NPTF) to spill into an open drain.

SERVICE ACCESS
Access to all serviceable components is provided by thefollow
ing removable panels:
• Blower service access
• Electrical/filter access
• Compressor service access
Refer to Figure 3 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 appli
ances. Follow manufacturer's instructions enclosed with the
thermostat for general installation procedure. Four or five color
coded insulated wires (minimum #18 AWG) should be used to
connect thermostat to unit. See Figure 2.

Cooling
SEQUENCE OF OPERATION
Heating
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 compres
sor and outdoor fan motor. If the fan switch on the thermo
stat is on the ”AUTO" position, the thermostat will also send
a 24 volt signal to “G” on the fan control board and the in
door blower will operate as indicated in step 1.
3. When the demand for cooling has been satisfied, the “M1"
contactor will be de-energized when the 24 volt ”Y" signal is
removed. If the fan switch on the thermostat is energized
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 willbe removed, andafter a
60 second delay, the “K1" relay will open and deenergize the indoor blower motor,
WITH POWER TO UNIT AND THERMOSTAT IN HEATING
MODE.
1. If the fan switch on the thermostat is in the “ON” position,
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 oper
ate only when there is a callfor 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 ener
gize 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
“ON” position, the indoor blower will continue to run. If the
-
fan switch isin the “AUTO” position, the “K1" relay will open
and de-energize the indoor blower motor after the appropri
ate time delay.
Please refer to Table 13 for more information.
