NOTE: If necessary, adjust fan OFF delay settings to obtain satis-
factory comfort level.

Unit Shutdown

1. Set the thermostat to lowest setting.
2. Turn off the electrical power supply to the unit.
3. Remove the heat exchanger door on the side of the unit by
removing screws.
4. Move the gas control valve switch to the OFF position. Do
not force.
5. Close manual gas shutoff valve external to the unit.
6. Replace the heat exchanger door on the unit.
7. If cooling and/or air circulation will be desired, turn ON the
electrical power.

OOLING TARTUP
NOTE: Check all manual reset limit controls in heating circuit if
cooling mode does not operate.
Compressor Protection Devices
The compressor includes components which are designed
to protect the compressor against abnormal operating
conditions.
T
O PREVENT PERSONAL INJURY OR DEATH, ALWAYS DISCONNECT ELECTRICAL
POWER BEFORE INSPECTING OR SERVICING THE UNIT.
PROTECTION DEVICES RESET AUTOMATICALLY, ENERGIZING THE CONTACTOR
AND OUTDOOR FAN.
Refrigerant Charge Check
After completing airflow measurements and adjustments the
unit's refrigerant charge must be checked. The unit comes factory
charged, but this charge is based on 325 CFM per ton and
minimum ESP per AHRI test conditions (generally between .15
-.28 ESP). When air quantity or ESP is different than above,
the refrigerant charge must be adjusted to the proper amount.
WARNING
A
LL COMPRESSOR
All package units with fixed orifice devices are charged using
the super heat method at the compressor suction line.
After superheat is adjusted it is recommended to check unit
sub-cooling at the condenser coil liquid line out. For charge
adjustments, see superheat and sub-cooling charts shown for
each model.

Cooling Operation
NOTE: Mechanical cooling cannot be reliably provided at ambient
temperatures below 50° F.
1. Turn on the electrical power supply to the unit.
2. Place the room thermostat selector switch in the COOL
position (or AUTO if available, and if automatic changeover
from cooling to heating is desired).
3. Set the room thermostat to the desired temperature.

The following presents probable causes of questionable unit
operation. Refer to Diagnostic Indicator Chart for an
interpretation of the signal and to this section for an explanation.
Remove the control box access panel and note the number of
diagnostic LED flashes. Refer to Diagnostic Indicator Chart
for an interpretation of the signal and to this section for an
explanation.

BNORMAL PERATION
Internal Control Failure
If the integrated ignition control in this unit encounters an
internal fault, it will go into a "hard" lockout and turn off the
diagnostic LED. If diagnostic LED indicates an internal fault,
check power supply to unit for proper voltage, check all fuses,
circuit breakers and wiring. Disconnect electric power for five
seconds. If LED remains off after restoring power, replace control.
External Lockout
An external lockout occurs if the integrated ignition control
determines that a measurable combustion cannot be established
within three (3) consecutive ignition attempts. If flame is not
established within the seven (7) second trial for ignition, the gas
valve is de-energized, 15 second inter-purge cycle is completed,
and ignition is reattempted. The control will repeat this routine
three times if a measurable combustion is not established. The
control will then shut off the induced draft blower and go into a
lockout state.
