SERVICE AND TECHNICAL SUPPORT MANUAL

Checklist

1. Put away tools and instruments. Clean up debris.
2. Verify that the jumper is removed from the TEST/TWIN
terminal. Verify that there is nothing plugged into the PLT
connector.
NOTE: If there is a jumper connector plugged into PLT, remove
it and discard. (See Figure 4)
3. Verify that the Blower/Heat Off Delay jumpers are set as
desired. (See Figure 4 and Figure 15)
4. Verify that the blower (lower door in upflow position) and
control ("Main" or upper door in upflow position) doors
are properly installed.

NOTE:
1. A filter is required for each return−air inlet. Airflow performance includes a 3/4 in. (19 mm) washable filter media such as contained in factory−authorized accessory
filter rack. See accessory list. To determine airflow performance without this filter, assume an additional 0.1 in. w.c. available external static pressure.
2. Blower speed taps are not always in the same order. Factory Default blower connections are as follows:
Heating airflow − BLUE (also used for Continuous Fan)
Cooling airflow − BLACK (enabled when the Y terminal is energized)
ADJUST THE BLOWER SPEED TAPS AS NECESSARY FOR THE PROPER AIR TEMPERATURE RISE FOR EACH INSTALLATION.
3. Airflows over 1800 CFM require bottom return, two−side return, or bottom and side return. A minimum filter size of 20" x 25" (508 x 635 mm) is required.
4. For upflow applications, air entering from one side into both the side of the furnace and a return air base counts as a side and bottom return.
5. Highlighted areas indicate that this airflow range is beyond the range allowed for heating. THESE AIRFLOW RANGES MAY ONLY BE USED FOR COOLING.

Specifications subject to change without notice.
5. Verify that the Status LED glows. If not, check that the
power supply is energized and that the blower door is
secure. See Figure 14 to interpret diagnostic codes
6. Cycle test furnace with room thermostat to be sure that it
operates properly with the room thermostat. Check all
modes including Heat, Cool and Fan.
7. Check operation of accessories per manufacturer's
instructions.
8. Review Home Owner's Information with owner.
9. Attach entire literature packet to furnace.
