CLEANING

It is advisable to keep dust build-up on warm surfaces to a minimum, since dust, in some cases, can be a
UM
combustible.
Dust build-up in the circulating fan can impair blower performance; therefore, reduce effi ciency.
The recovery coil is located immediately above the blower assembly. Over time, it may become coated with
dust. To clean the recovery coil:
1. Turn off electrical power to the furnace.
2. Remove the blower access door
3. Remove the screws fastening the blower assembly to the blower division panel.
LABEL ALL WIRES PRIOR TO DISCONNECTION WHEN SERVICING CONTROLS.
WIRING ERRORS CAN CAUSE IMPROPER AND DANGEROUS OPERATION.
4. Unplug harness from blower division, junction box and remove thermostat wires (label wires to correct
position).
5. Pull the blower assembly out.
6. Once the blower assembly has been removed, the coils may be vacuumed with the soft brush attachment.
