loose debris. Such material could clog the blower motor air ducts and reduce the air flow through the
blower motor.

problems using the "Troubleshooting" section.
Keypad Operation

again before the cycle ends will stop the blower motor. Note that this product also has an automatic
purge cycle, which initiates about 30 minutes after the blower has stopped.
