1. Apply power to the DEDPV-705
The blue light on the indicator panel only illuminates when the DEDPV-705 is operating.
2. The DEDPV-705 turns ON approximately 10 seconds after the dryer has started by sensing the pressure inside the exhaust duct. A
blue LED will illuminate (solid) on the indicator panel when the DEDPV is operating.
3. Once ON, the DEDPV-705 will run continuously for 5 minutes.
4. After 5 minutes, the fan will temporarily turn off to verify the status of the dryer. If the dryer is still running and positive pressure is
sensed within the exhaust duct, the DEDPV-705 will re-energize and run another 5-minute cycle. The indicator panel will remain lit
during this verification step.
The verification check takes approximately 30 seconds.
5. If after a complete 5 minute run cycle the DEDPV does not sense pressure from the dryer, the DEDPV-705 will engage in a final
5-minute cool-down cycle before turning OFF.
Since fan bearings are sealed and provided with an internal lubricating material, no additional lubrication is necessary.
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 once a year.
Excessive 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. Loosen the 4 fast clamps and remove the 10-inch extender ducts from the fan inlet and outlet; remove any lint buildup on the
impeller and near the outlet.
C. Reconnect the duct to the fan. Turn power supply on.
