J. WINTERIZING
UNIT DAMAGE HAZARD
Failure to follow this caution may result in furnace
component damage.
Freezing condensate left in the furnace may damage the
furnace.
CAUTION
!
If the furnace will be off for an extended period of time in a
structure where the temperature will drop to 32_F(0_C) or
below, winterize a s follows:
1. Turn off electrical supply to furnace.
2. Remove main furnace door.
3. Disconnect upper inducer housing drain connection cap
from inducer housing. (See Fig. 18.)
4. Connect field-- supplied 1/2--in. I.D. inducer housing tube
to upper inducer housing drain connection.
5. Insert funnel in tube and pour one quart of antifreeze,
propylene glycol (RV, swimming pool antifreeze, or
equivalent) into funnel/tube until it is visible at point
where condensate enters open drain. (See Fig. 19.)
UNIT DAMAGE HAZARD
Failure of plastic components may occur.
Do not use ethylene glycol (Prestone II antifreeze/coolant or
equivalent automotive type).
CAUTION
!
6. Replace drain connection cap and clamp to inducer
housing.
7. Replace main furnace door.
8. Propylene glycol need not be removed before restarting

TROUBLESHOOTING
Use the troubleshooting guide, the status code LED on the
furnace control and the component test to isolate furnace
operation problems.
A more detailed troubleshooting guide is available from your
distributor.
For an explanation of status codes, refer to service label located
on back of main furnace door (See Fig. 20.)
The furnace control stores all status codes for a period of 72
hours, regardless of 115-- v or 24--v power interruption.
NOTE: Removing blower access panel opens blower access
panel door switch and terminates 115-- v power to furnace control.
Before removing blower access panel or turning of f 115--v power,
look into blower access panel sight glass for current LED status.
1. To retrieve status code, proceed with the f ollowing:
NOTE: NO thermostat signal may be present at furnace control
and all blower time delay periods must be completed.
a. Leave 115--v power to furnace turned on.
b. Remove main furnace door.
c. Lookintobloweraccesspanelsight glassfor currentLED
status code.
d. Remove blower access panel.
e. Turn setup switch SW1 --1 to ON position. (See Fig. 16
or 21 for location.)
f. Manually close blower access panel door switch. Use a
piece of tape to hold switch closed.
