Calculating Duct Run
To calculate the length of your planned duct run, measure from the dryer to external venting point in roof or wall. For each bend or elbow add 5-7
feet to your total duct run calculations. The DBF4XLT-705 can be used on runs up to 130 feet.
Fan and Switch Mounting
The DBF4XLT-705 is to be mounted a minimum of 5 linear (not
equivalent) feet from the dryer outlet. Exception: A secondary lint trap
can be used where required and in applications where excessive dryer
lint generation is likely or to increase the time interval between routine
maintenance of the (DEDPV). (See illustration to the right.). An MB
mounting bracket (included) attached to a rafter or joist should be used
to stabilize the fan. The duct work to the inlet of the DBF4XLT-705 is to
be attached with the FC4 clamp (included) to permit periodic inspection
of the blower. Refer to maintenance instructions for inspection
recommendations. All duct connections should be properly sealed to
prevent leakage and loss of fan performance. Flex duct (if allowed by
building codes) should be stretched as smooth as possible.
Indicator Panel
The DBF4XLT-705 is equipped with a remote mounted low voltage
operation indicator panel. This panel contains an LED that will indicate
proper operation of the (DEDPV). In the event of a problem with the
system, it will indicate the nature of the problem. The panel must be
mounted in the 2 gang decora switch plate with warning label
(furnished).
Pressure Sensor Switch
Operation
The DBF4XLT-705 contains a positive pressure sensing switch which
recognizes dryer operation and activates the (DEDPV) from an
independent electrical circuit. This eliminates connections through the
dryer circuit which may void the manufacturers' warranty as well as
manual systems which require the attention of the operator or costly
current/temperature sensing systems.
Power to the (DEDPV) is provided through the attached 120VAC
power cord. A pressure tap is connected to a nipple on the side of
the switch. When the dryer begins operation, positive pressure in the
duct causes the switch diaphragm to expand closing the circuit to the
(DEDPV).
