READ AND SAVE THESE INSTRUCTIONS
WARNING — TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK OR INJURY TO PERSONS, OBSERVE
THE FOLLOWING :
A - Your dryer installation incorporates a dryer exhaust power ventilator (DEDPV)
incorporating a lint trap.
B - Your dryer depends on the DEDPV for its safe and e󱐰cient operation. Operating your
dryer without a functional DEDPV will result in ine󱐰cient dryer operation, excess energy
consumption and a possible re hazard. See warning light on DEDPV front panel.
C - The VTX-DEDPV shall be permanently installed within the space in which the dryer
is installed. In the case of a dryer installed in an alcove provided with a door, the DEDPV
shall be installed within the alcove or be installed immediately adjacent to the doors of the
alcove. The DEDPV shall be located where it will be readily visible after the dryer is installed
without opening any doors other than those necessary to access the dryer.
WARNING — IF A CONTINUOUS ALARM SOUNDS OR A VISUAL ERROR INDICATOR IS PRESENT,
DO NOT OPERATE THE CLOTHES DRYER. CONTACT YOUR SERVICE PERSONNEL
• Do not install in an exhaust ductwork of a clothes dryer whose instructions prohibit the
installation of a clothes dryer booster fan (DEDPV).
• Do not install in an exhaust ductwork where the equivalent duct length is less than 25 ft
(7.62 linear metres).
• The VTX-DEDPV is suitable to overcome an equivalent duct length of 130 feet
(39.6 meters) of 4 inch diameter galvanized steel duct, and to maintain an air velocity
of 1200 fpm (6.10 m/s).
• Do not exhaust air in excess of 167F (75C) and do not install less than linear 4ft (1.21m)
from clothes dryer exhaust outlet.
• Do not install less than 4 linear feet (1.21 linear meters) or more than 45 linear feet (13.71
linear meters) from clothes dryer exhaust outlet.
• Insulated dryer duct shall not be used upstream of the ventilator.
• The ventilator must not be used in conjunction with high output dryers.
• For general ventilating use only. Do not use to exhaust hazardous or explosive materials
and vapors.
• The installation must comply with local electrical and mechanical building codes,
and must be inspected and accepted by local authorities having jurisdiction.

Calculating duct run for secondary lint trap
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 feet (1.52 meter) to your total duct run calcu-
lation. The VTX-DEDPV can be used on runs up to 130 feet (39.6 meter).
Fan location
The VTX-DEDPV is to be mounted a minimum
of 4 linear feet (1.21 meter) and not more
than 45 linear feet (13.71 linear meters) from
clothes dryer exhaust outlet. A secondary lint
trap can be used where required and in appli-
cations where excessive dryer lint generation
is likely to increase the time interval between
routine maintenance of the dryer booster fan.
The VTX-DEDPV is to be attached with the 4
ADC4 clamps (included) to permit periodic
inspection of the blower. Refer to mainte-
nance instructions for inspection recommen-
dations. All duct connections should be prop-
erly sealed to prevent leakage and loss of fan
performance.

STEP 1 — Install the mounting bracket on both side of
the fan
REMARQUE : Fan mounting can be done at any angle
however, vertical mounting is recommended to reduce
condensation buildup in the fan. If a horizontal installa-
tion is necessary and condensation buildup may pose a
problem, a 1/4” (6 mm) hole drilled in the bottom of the
housing (along with an NPT insert (by others) and drain
tubing) may be installed to allow condensation to drain.
STEP 2 — Mount the fan
Using wood screws provided, attach the mounting
bracket to a support beam at the selected location. For
proper operation, the control box (located on the fan)
needs to be positioned to provide access to the indica-
tor panel RJ12 female connector and the tubing con-
nections.
STEP 3 — Install acces duct on inlet and oulet and se-
cure with ADC4
Install the 8 ” long cleanout duct using the ADC4 duct
clamps. See dimensional data on next page.
STEP 4 — Install acces duct on inlet and oulet and secure with ADC4
Drill a 1/4 inch diameter hole in the inlet duct wall 4 to 8 inches from the inlet of the fan. Carefully
insert the grommet into the hole.
Do not connect the tubing in such a manner as to allow condensation from the duct to collect in
the tubing. Mark the opposite end of the pressure tubing ½ inch from the edge and insert into
the grommet until the marking is reached.
Indicator panel
The VTX-DEDPV is equipped with a remote mounted low voltage operation indicator panel. This
panel contains a RGB LED that will indicate proper operation of the booster fan. In the event of a
problem with the system, it will indicate the nature of the problem.

Indicator panel installation
STEP 1 — Selecting panel location
The VTX-DEDPV indicator panel mounts near the dryer
in a location that will be visible to the operator of the
dryer. The indicator panel is supplied with 50 feet (15.2
meter) of cable. Ensure that the indicator panel and
booster fan are located to allow their connection with
this cable.
STEP 2 — Connection and mounting panel
The indicator panel is a low voltage device that is not
required to be installed in an electrical junction box. If
provided with clearance for the cable and terminal block
it can be mounted to a wall using appropriate fasteners.
If installer chooses to mount indicator panel in a single
gang junction box (by others), it should not be installed
in a box that contains high voltage wiring or devices.
Both end of the 50 foot (15.2 meter) cable have a RJ12
male connector.
STEP 3 — Warning label
Install waining label sticker next to the indicator panel. The VTX-DEDPV is equipped with a re-
mote mount, low voltage, operation indicator panel. This wall-mounted indicator panel contains

a RGB LED that is intended to visually alert the occupant of any detected faults.
STEP 4 — Connect indicator panel cable to the fan
Connect both end RJ12 of the 50 foot (15.2 meter) cable, one end to the fan jonction box female
connector and one end the the female connector on the back of the indicator panel.
VTX-DEDPV Calibration procedure
IMPORTANT — Make sure all of the following are performed before supplying power to the
VTX-DEDPV. Conrm the VTX-DEDPV and the entire duct system is completely installed and clear
of lint. (Required for proper calibration)

Page : 7
• Conrm the dryer is o󱐯 and cool.
• Conrm all lint traps are empty of lint and reinstalled in their proper position.
• Conrm the dryer is empty of clothing.
• Conrm the door on the dryer is closed.
• Supply power by plugging in the power cord or cycling the power circuit that supply the
VTX-DEDPV
NOTE — Within 10 seconds of the VTX-DEDPV dryer booster being supplied power, it will come
on and run for up to 15 - 20 seconds. This is a calibration period and will only happen when the
VTX-DEDPV is rst powered, LED is ashing blue during calibration mode and after calibration
mode motor and LED will shut o󱐯. The VTX-DEDPV is now calibrated and the clothes dryer can be
used.
NOTIFICATION PANEL STATUS MODE
CALIBRATION MODE (Flashing blue LED)
PROPER VENTING MODE (Steady green LED)
When the VTX-DEDPV is on, the green LED will be continuously on.
PRESSURE FAULT MODE (Flashing orange LED) If at anytime during the calibration or operating
cycle of the VTX-DEDPV and the dryer there is excessive pressure sensed, the notication panel
will ash the orange LED. The VTX-DEDPV will continue to operate to try to clear the blockage.
Stop the dryer immediately and have the vent system inspected by someone qualied to do so.
The power to the VTX-DEDPV will need to be removed to clear the fault condition and turn the
VTX-DEDPV motor o󱐯. The VTX-DEDPV calibration cycle will need to be performed. (See trouble-
shooting for complete details)
CIRCUIT FAILIURE MODE (Flashing pink LED).
If at anytime during the calibration or operating cycle the VTX-DEDPV is not fonctionning proper-
ly due to a circuit or motor failiure stop the dryer immediately, turn o󱐯 power of the VTX-DEDPV
and contact the manufacturer.
TEMPERATURE FAULT MODE (Flashing red LED) The VTX-DEDPV has a non-resettable thermal
fuse link which will trigger when exhaust temperatures exceed 196°F. This is a safety feature de-
signed to prevent the VTX-DEDPV from operating during abnormal/dangerous drying conditions.
Call technical support for authorization before opening the electrical compartment; check resis-
tance across the thermal overload protector.
RECOMMENDED MAINTENANCE
Depending on use, but at least once a year, we recommend cleaning the dryer exhaust vent. On
an annual basis, make sure that exhaust hood apper or backdraft damper is clean of lint and
moves freely. The VTX-DEDPV motor is maintenance free. If the VTX-DEDPV is acting erratically,
perform the calibration procedure.
Fan impeller may accumulate lint. Periodic inspection, based upon dryer usage, should be per-
formed to ensure that the fan impeller is not obstructed or loaded with lint.

To inspect and clean the impeller :
• Disconnect the incoming power supply at the source.
• Loosen the ADC4 fast clamps and remove the 8-inch extender ducts from the fan inlet
and outlet; remove any lint buildup on the impeller and near the outlet.
• Reconnect the duct to the fan. Turn power supply back on to recalibrate the unit.
WARNING — Do not blow into the pressure sampling tube in the direction of the circuit board.
The pressure sensor is a very sensitive device that can be destroyed if subjected to the pressure
created by someone blowing strongly into it.
TROUBLESHOOTING
IMPORTANT — All faults are indicated by a di󱐯erent colored LED light or no lights on notica-
tion panel. Faults must be investigated as outlined below and must only be cleared once a thor-
ough investigation of the dryer vent system and dryer has been performed by someone qualied
to do so. Perform VTX-DEDPV calibration procedure to clear any faults once investigation is com-
pleted.
No indicator light | VTX-DEDPV not operating when dryer runs.
• The VTX-DEDPV is interlocked to the dryer by sensing the pressure inside the exhaust
duct when the dryer turns on. Replace the tubing if damage is observed.
• Dryers are equipped with operating temperature controls that monitor drying
temperatures. Normal exhaust temperatures should not exceed 167°F. If the safety
thermal fuse in the VTX-DEDPV trips, the dryer is operating outside its limits. Contact
the dryer manufacture and replace the VTX-DEDPV.
• If the dryer is operating and there is no green LED on the notication panel, stop the
dryer immediately and have the vent system inspected by someone qualied to do so.
PRESSURE FAULT MODE (Flashing orange LED)
If at anytime during the calibration or operating cycle of the VTX-DEDPV and the dryer there is
excessive positive pressure of +0.16” W.C. sensed for over four minutes, the notication panel will
ash the orange LED. Stop the dryer immediately and have the vent system inspected by a per-
son qualied to do so. This is an indication of excessive back pressure in the vent system.
