OPERATION
DBF-DEDPV Calibration procedure
IMPORTANT — ENSURE ALL OF THE FOLLOWING ARE PERFORMED BEFORE SUPPLYING POWER
TO THE DBF-DEDPV.
• Confirm that the power of the clothes dryer is turned off.
• Confirm all lint traps are empty of lint and reinstalled in their proper position.
• Confirm the clothes dryer is empty of clothing.
• Confirm the door on the dryer is closed.
• From the electrical panel, turn on the power to the DBF-DEDPV.
NOTE — Within 10 seconds of the DBF-DEDPV being powered on, it will come on and run for up
to 20 seconds. This calibration period will only happen when the DBF-DEDPV is powered for the
first time. The blue indicator light will flash during calibration mode and after calibration mode,
the motor and the light will shut off.
The DBF-DEDPV is now calibrated and the clothes dryer can be used.
NOTIFICATION PANEL STATUS MODE
CALIBRATION MODE (Flashing blue light)
PROPER VENTING MODE (Steady green indicator light)
When the DBF-DEDPV is on, the green indicator light will be continuously on.
PRESSURE FAULT MODE (Flashing orange indicator light)
If, at any time during the calibration or operating cycle of the DBF-DEDPV, a flashing orange
indicator light appears, the DBF-DEDPV pressure sensor is detecting a rise of static pressure in the
duct due to a blockage to the system. The DBF-DEDPV will continue to work but you must stop
the clothes dryer immediately and have the vent system inspected by a qualified service provider.
The power to the DBF-DEDPV will need to be turned off to turn the DBF-DEDPV motor off so you
can clear the faulty duct condition and/or remove the obstruction. The DBF-DEDPV calibration
cycle will need to be performed once more. (See Troubleshooting for complete details)
CIRCUIT FAILURE MODE (Flashing pink indicator light)
If, at any time during the calibration of operating cycle a flashing pink indicator light appear the
DBF-DEDPV is not functioning properly due to a circuit or motor failure, stop the dryer immedi-
ately, turn off the power of the DBF-DEDPV and contact the manufacturer.
TEMPERATURE FAULT MODE (Flashing red indicator light)
The DBF-DEDPV is equipped with a non-resettable thermal fuse link which will trigger in case of a
fire. This is a safety design feature to prevent the DBF-DEDPV from operating during abnormal or
dangerous drying conditions. If this occurs, contact the manufacturer.
