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.
CLEARANCES
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.
NOTE: Be sure to note supply and return openings.
WARNING: Do not permit overhanging structures or shrubs to
obstruct the condenser air discharge outlet.
Refer to Figure 3 for information concerning rear and bottom
supply and return air duct openings.
DUCT WORK
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).
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:
A filter rack and high velocity filters are standard on three
phase units.
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).
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.
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 duct covers with silicone caulk.
Filters should be checked monthly especially since this unit is
used for both heating and cooling.
Downflow units must have an “L”-shaped supply duct without
any outlets or registers located below the outlet of the unit.
CONDENSATE DRAIN
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.
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.

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. Six color coded
insulated wires (minimum #18 AWG) should be used to connect thermostat to unit. See Figure 2.
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.
POWER AND CONTROL WIRING
COMPRESSORS
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

Checking Supply Air CFM
curate. To ensure 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:
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.
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.
WARNING! Failure to properly adjust the total system air
quantity can result in extensive system damage.
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 inac-
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
Anti-short Cycle Timer
This unit has an anti-short cycle timer built in to the defrost control. This timer will not permit the compressor to start within five
minutes after the completion of the last cycle or power interruption. To bypass the anti-short cycle feature, short the “TEST”
pins together for 2 seconds.
The following sequences of operation are based on using a
standard single-stage heat pump thermostat.
Cooling Operation
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 on the thermostat
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”
and “O” on the fan control board. After the anti-short cycle
period is complete,The 24 volt signal will energize contactor “M1", and the reversing valve solenoid. Power will be
supplied to the compressor and outdoor fan motor, and the
reversing valve will switch to the cooling position. If the fan
switch on the thermostat is on the ”AUTO" position, the fan
control will energize the indoor blower.
3. When the demand for cooling has been satisfied, the 24
volt “Y” signal is removed and the “M1" contactor will be deenergized. 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 a 60 second delay,
Heating Operation
WITH POWER TO UNIT AND THERMOSTAT IN HEATING
MODE.
stat 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.
Please refer to Tables 7 and 8 for more information.
Defrost Operation
The minimum time between defrosts can be field selected at
30, 60 or 90 minutes. The default time is 90 minutes if the
jumper is not installed.
Defrost will initiate when the defrost sensor, located on the outdoor coil, senses a temperature below 31°F and when the time
since the last defrost is greater than the selected time on the
defrost control. The defrost cycle terminates when either the
defrost sensor reaches 55°F or the unit has been in defrost
mode for 10 minutes. If the room thermostat opens during defrost, the unit will resume operation in defrost when the thermostat re-closes.
During the defrost mode, the defrost control will provide a 24
volt signal from terminal “W1/66" to the fan control terminal
”W1". This signal will energize electric heat stage 1, if the unit is
so equipped.
For trouble shooting purposes, the defrost cycle can be manually initiated by shorting the “TEST” pins together for 5 seconds. Defrost will terminate normally during the “TEST” mode.
Heat Pump Safety Switch Operation
If the unit is equipped with the field installed upgrade safety
package, the refrigeration system will be protected against
high or low refrigerant pressure and low indoor coil temperature. If any of these three safety switches opens, the unit will be
shut off for the 5 minute anti-short cycle time. Once this has expired, a six hour elapsed run timer begins. If a second opening
of a safety switch occurs during this six hour period, the compressor will be locked out.
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 on the thermostat
is in the “AUTO” position, the blower will operate only when
there is a call for heating by the thermostat.
Resetting the lockout function is accomplished by;
2. On a call for heating, the thermostat will send 24 volts to “Y”
on the fan control board. After the anti-short cycle period is
complete, the 24 volts signal will energize contactor coil
“M1" and power will be supplied to the compressor and outdoor fan motor. The reversing valve will remain in the heating position. If the fan switch on the thermostat is in the
”AUTO" position, the fan control will energize the indoor
blower.
3. Shorting the “TEST” pins together for more than 2 seconds.
3. For units equipped with supplementary electric heat, if the
heat pump cannot meet the demand, the thermostat “W”
will send 24 volts to “W2" on the fan control board. This signal will also be sent through the defrost control terminals
”W" and “W1/66" and back to the fan control ”W1". This 24
volt signal will energize all stages of electric heat.
4. When the heating demand is satisfied, the electric heat will
be de-energized when the 24 volt “W” signal is removed,
and the “M1" contactor will be de-energized when the 24
volt ”Y" signal is removed. If the fan switch on the thermo-
1. Removing power from the control's thermostat 1st stage
(Y) input for a time not to exceed 5 seconds (ON-OFF-ON).
2. Removing power from “R” for more than 2 seconds.
Electric Heat Limit Switch Operation
The limit switch responds to over temperature conditions in the
air duct. Opening of the device results in dropping power to the
relays. The control logic will also respond by turning off the relays. After four limit cycle trips the unit goes into a 1 hour soft
lockout period. If during this period the control “sees” another
limit cycle, the unit will go into a hard lockout condition. Once in
a hard lockout state, the fan is locked on and the heaters are
disabled. Only a power cycle will clear the state.
During the soft lockout period, the fan responds to thermostat
input but the heaters are enabled. This is to sense a failed
heater relay. The limit cycle count is reset at the start of a heat
request. If the limit remains open for period of 80 seconds or
more, the control is immediately put into a hard lockout condition. Only a power cycle will clear this state.
SECURE OWNER'S APPROVAL: When the system is functioning properly, secure the owner's approval. Show him
the location of all disconnect switches and the thermostat. Teach him how to start and stop the unit and how to adjust temperature settings within the limitations of the system.
