Recommended Maintenance; Error Indications - Fantech DEDPV-705 Manuel D'installation Et D'opération

Recommended Maintenance

1. Since fan bearings are sealed and provided with an internal lubricating material, no additional lubrication is necessary.
2. Fan impeller may accumulate lint. Periodic inspection, based upon dryer usage, should be performed to ensure that the fan impeller is not
obstructed or loaded with lint. Under normal conditions, fan should be inspected a minimum of every Six (6) Months. Note: Excessive booster fan
noise or vibration may be an indication of lint buildup on the impeller. To inspect and clean the impeller:
a. Disconnect the incoming power supply at the source.
b. Remove the duct from the fan inlet and remove any lint buildup on the impeller.
c. Reconnect the duct to the fan. Turn power supply on.
Troubleshooting
This is a simple procedure to verify proper operation of the booster fan. It should be run at setup to verify that the system is operating correctly. In
normal operation the system will indicate the status of the booster fan; however, this process can also be repeated as a system diagnostic.
a. Generally, if the indicator LED is not illuminated it is OK to run the test. Should you notice any behavior other than that described below, shut
the dryer off and wait at least 5 minutes to allow the system to reset and then run the test again.
b. Start the dryer and run it for a period of 1 minute.
c. The indicator LED should illuminate about 10 seconds after the dryer starts.
d. The booster fan should stop 5 to 10 minutes after the dryer stops.
e. Indicator LED should remain illuminated for 5 to 10 minutes after the dryer stops.
f. If indicator LED does not illuminate or flashes, see error indication section. Otherwise, the booster fan is functioning correctly.

Error Indications

If the LED flashes or does not illuminate, check the list below for error indication and likely sources of the problem. Should your DEDPV-705 show an
error other than what is listed, or if these help topics do not solve the problem, please contact Fantech's Technical Assistance Department for
further assistance.

1. The LED illuminated in a steady state indicates that the Dryer Booster Fan is operating properly.
2. If LED does not illuminate when clothes dryer is on, check the booster fan operation.
• If it is not working, verify that the booster fan is properly connected to a 120V AC power source.
• Verify that there are no obstructions in the duct between the clothes dryer and the Dryer Booster Fan.
• Verify that the clear plastic tubing is connected between the nipple on the Dryer Booster Fan and the clothes dryer duct (see Step 5 of Fan
Installation).
• If it is working
• Verify that the low voltage wire is properly plugged into the booster fan.
• Check the polarity of the low voltage connection to the indicator panel (red to positive, black to negative). If the polarity is reversed the LED will
not illuminate.
3. LED flashes evenly
• This indicates a locked rotor condition. The fan is receiving power, but the motor is not turning. Check the booster fan for obstruction or motor
failure.
4. LED flashes twice followed by a brief pause
• This indicates that the booster fan is operating at less than its standard speed. Check the boost fan for buildup of debris or motor damage.
5. LED flashes three times followed by a brief pause
• This is indicating that the system airflow has dropped. Check duct system for obstructions. LED flashes that appear after the clothes dryer has
turned off are a result of decreased airflow through the duct system caused by the clothes dryer turning off and does not require any action. If
LED flashes are present when the clothes dryer is running, corrective action should be taken.
