115-Volt Line Connection of Accessories—Electronic
Air Cleaner
WARNING
HIGH VOLTAGE!
Goodman 6
Disconnect ALL power before servicing.
Multiple power sources may be present.
Failure to do so may cause property damage,
personal injury or death.
The furnace's integrated control module is equipped with
line-voltage accessory terminals for controlling power to an
optional field-supplied electronic air cleaner.
The accessory load specifications are as follows:
Electronic Air Cleaner—1.0 Amp maximum at 120 VAC
NOTES:
Turn off power to the furnace before installing any
accessories.
Follow the air cleaner manufacturers' instructions for locating,
mounting, grounding and controlling these accessories.
Accessory wiring connections are to be made through the ¹⁄₄"
quick connect terminals provided on the furnace integrated
control module.
The electronic air cleaner hot terminal is identified as EAC-H.
The electronic air cleaner neutral terminal is identified as LINE
NEUTRAL.
Resetting from Lockout
Furnace lockout results when a furnace is unable to achieve
ignition after 3 attempts. It is characterized by a non-functioning
furnace and a one 1-flash diagnostic LED code. If the furnace is
in "lockout," it will (or can be) reset in any of the following ways.
1. Automatic reset. The integrated control module will
automatically reset itself and attempt to resume normal
operations following a 1 hour lockout period.
2. Manual power interruption. Interrupt 115-volt power to the
furnace for 1 to 20 seconds.
3. Manual thermostat cycle. Lower the thermostat so that there
is no longer a call for heat then reset to previous setting.
Interrupt thermostat signal to the furnace for 1 to 20 seconds.
NOTE: If the condition which originally caused the lockout still
exists, the control will return to lockout. See "Troubleshooting."
Annual Inspection
The furnace should be inspected by a qualified installer, or
service agency at least once per year. This check should be
performed at the beginning of the heating season. This will
ensure that all furnace components are in proper working order
and that the heating system functions appropriately. Pay
particular attention to the following items. Repair or service as
necessary.
Flue pipe system. Check for blockage and/or leakage. Check
the outside termination and the connections at and internal to
the furnace.
All field wiring must conform to applicable codes.
Optional Accessories Wiring
Connections should be made as shown below.
A. Electronic air cleaner (optional)
B. EAC-H
C. 120 VAC hot and park terminals
If it is necessary for the installer to supply additional line
voltage wiring to the inside of the furnace, the wiring must
conform to all local codes, and have a minimum temperature
rating of 105°C.
All line voltage wire splices must be made inside the furnace
junction box.
The integrated control module electronic air cleaner terminals
(EAC) are energized with 115 volts whenever the circulator
blower is energized.
MAINTENANCE
Heat exchanger. Check for corrosion and/or buildup within
the heat exchanger passageways.
Burners. Check for proper ignition, burner flame, and flame
sense.
Drainage system. Check for blockage and/or leakage. Check
hose connections at and internal to furnace.
Wiring. Check electrical connections for tightness and/or
corrosion. Check wires for damage.
Filters
Maintenance
Improper filter maintenance is the most common cause of
inadequate heating or cooling performance. Filters should be
cleaned (permanent) or replaced (disposable) every 2 months or
as required. When replacing a filter, it must be replaced with a
filter of the same type and size.
Filter Removal
Depending on the installation, differing filter arrangements can be
applied. Filters can be installed in either the central return register
or a side panel external filter rack (upflow only). A media air filter
or electronic air cleaner can be used as an alternate filter. Follow
the filter sizes given in the Recommended Minimum Filter size
table to ensure proper unit performance.
