CLEARANCES
FILTERS
All units require certain clearances for proper operation and
service. Refer to Figure 3 for the clearances required for combustion, construction, servicing and proper unit operation.
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).
WARNING: Do not permit overhanging structures or shrubs to
obstruct the condenser air discharge outlet.
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.
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:
Filters should be checked monthly especially since this unit
may be used for both heating and cooling.
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).
CONDENSATE DRAIN
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.
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.
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.
SERVICE ACCESS
Access to all serviceable components is provided by the following removable panels:
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.
• Blower service access
• Electrical/filter access
• Compressor service access
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.
Refer to Figure 3 for location of these access panels and minimum clearance.
THERMOSTAT
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.
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 or five color
coded insulated wires (minimum #18 AWG) should be used to
connect thermostat to unit. See Figure 2.
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.

Checking Supply Air CFM
a dry coil, the compressors should be deactivated while the test
is being run.
To check the supply air CFM after the initial balancing has been
completed:
1.Remove the two ¼ inch dot plugs in the duct panel.
2.Insert at least 8 inches of ¼ inch tubing into each of these
holes for sufficient penetration into the airflow on both sides of
the indoor coil.
3.Using an inclined manometer, determine the pressure drop
across the dry evaporator coil. Since the moisture on an evaporator coil may vary greatly, measuring the pressure drop across
a wet coil under field conditions would be inaccurate. To ensure
4.Knowing the pressure drop across a dry coil, the actual CFM
through the unit can be determined from the curve in Coil Delta
P vs. Supply Air CFM figure.
WARNING! Failure to properly adjust the total system air quantity can result in extensive system damage.
After readings have been obtained, remove the tubes and reinstall the two ¼ inch plugs removed in Step 1.
NOTE: De-energize the compressors before taking any test
measurements to ensure a dry indoor coil.

SEQUENCE OF OPERATION
Cooling
Heating
The following sequences of operation are based on using a
standard single-stage cooling thermostat.
WITH POWER TO UNIT AND THERMOSTAT IN HEATING
MODE.
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 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.
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 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.
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.
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 is in the “AUTO” position, the “K1" relay will open
and de-energize the indoor blower motor after the appropriate time delay.
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 will be removed, and after a
60 second delay, the “K1" relay will open and deenergize the indoor blower motor,
