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.

5. Verify that the Status LED has heartbeat (bright

−

dim). 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.

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.
