1.To check the temperature rise through the unit, place thermometers
in the supply and return air ducts as close to the unit as possible.
2.Open ALL registers and duct dampers.
6. Reset thermostat fan switch to AUTO. The circulating air blower
should go OFF after a 30 second delay. Nothing should be running.
Cooling
1. Be sure that electric power is OFF.
2. Set thermostat Heat-Cool select to COOL.
3. Adjust thermostat setting to below room temperature.
4. Turn electric power ON. During power application check the follow-
ing:
a. Contactor- Contactsclosing
b. Compressor- ON
c. Condenserfan motor- ON
d. Circulatingair blower- ON (afterdelay)
5.Switch the thermostat to OFF, check the following:
a. Contactorcontactsopening.
b. Compressor- OFF
c. Condenserfan motor- OFF
d. Circulatingblower - OFF(afterdelay)
6.Turn electric power OFF

NOTE: Repeat circulatingairblower procedureaboveif AuxiliaryElectricHeat is being
installedafterunit hasbeen installedand checkedout.
3.Set thermostat Heat-Cool selector to HEAT.
4.Set the thermostat temperature setting as high as it will go.
5.Turn electric power ON.
6.Operate unit AT LEAST 5 minutes, then check temperature rise.
NOTE: The maximum outlet air temperature for all models is 200°F
(93.35C). Maximum temperature rise for electric heat is 60°F (33.35C)
7.Set thermostat to normal temperature setting.
8.Turn electric power OFF.
9 Change blower speed tap if 60°F (33.3°C)TemperatureRisewasexceeded
and repeat.
10.Be sure to seal all holes in ducts if any were created during this
process.
Sequence of Operation
CoolingMode: Energized(R,G,YI) De-energized(N/A)
(a) When high and low voltage is initially applied to unit:
(f)On a call for cooling ......... :
The compressor and condenser fan will energize. The evaporator
blower motor will have a delay on and will energize after 30 seconds.
Temperature Rise Check

NOTE:The temperaturerisecan beadjustedby changingthe heating speedtap at the
unit'sblowerterminalblock.Referto the unit'sInstallationInstructionsfor airflowinforma-
tion.
(2)When the cooling setpoint has been satisfied ......... :
The compressor and condenser fan will de-energize immediately.
The evaporator blower motor will have a delay off and will de-ener-
gize after 30 seconds.
if temperature rise is excessive, verify proper airflow through the unit. if
temperature rise is inadequate, check for proper electrical supply to the
heater and verify correct airflow.
8. Operation
Electrical shock hazard.
Turn OFF electric power supply at disconnect switch or ser-
vice panel before removing any access or service panel from
unit.
Failure to follow this warning can result in property damage,
personal injury, and/or death.

CAUTION
Do NOT operate unit on cooling when the outdoor temperature is be-
low 60°F. This is necessary to prevent possible damage to the com-
pressor.
Turning The Unit Off

1.Set the thermostat selector switch to OFF and set the fan switch to
AUTO. To restart, set thermostat selector switch to COOL or HEAT
and set thermostat to temperature desired.
2.To shut the unit down completely, turn electric high voltage power
OFF
