PRODUCT CONTENTS

INSTALLATION

MOUNTING

STEP 1
Remove the tube from the differential pressure switch.
Unscrew the bolts on both sides from the plastic rings using a Phillips screwdriver.

STEP 2
Remove the motor box from the flange bracket. Remove the wind circle between the motor box and the intake flange.

STEP 3
Use the flange bracket to set your desired fan position. Mark the four mounting holes.
Your fan MUST be mounted at least 5 ft. away from the ventilation outlet.

STEP 4
Drill four holes into the marked locations. Make sure your mounting area is structurally sound and free from obstruction.

STEP 5
If you are mounting onto anything other than a wood support or stud, insert the included four wall anchors into the drilled mounting holes.
You may need to use a hammer to secure them through the holes.

STEP 6
Align the flange bracket’s holes with the wall anchors. Screw in four wood screws with a screwdriver or drill to secure the flange bracket.
Make sure its airflow arrow is pointing in your desired direction.

STEP 7
Place the wind circle back into the intake flange.

STEP 8
Slide the motor box back into the flange bracket, making sure its airflow arrow is pointing in the same direction as the flange bracket’s arrow.
Screw the bolts back into the plastic rings to secure the motor box to the flange bracket.
Place the tube back onto the differential pressure switch. Make sure to insert the tube over the positive outlet. See page 7 for more information.

STEP 9
When installing ducting, use duct clamps (sold separately) to secure it to either end of your duct fan, making sure there is a tight seal.
Tighten the duct clamps using a flathead screwdriver.

Do NOT move the fan after it is fully installed. Movement of the fan unit may result in false triggers as a result of changing differential pressure and will require recalibration. See page 23 for recalibration steps.

CONFIGURATION SETUP

ONMIDIRECTIONAL MOUNTING
Your fan can be mounted horizontally, vertically, or diagonally in extended ductwork, crawlspace, and dryer exhaust applications. It must be mounted tightly with your desired ducting.
To achieve optimal ventilation, make sure your fan’s mounting location is free of obstruction as specified on the product warning page.
Make sure your exhaust is flowing towards your ventilation source using the arrow as a guide.

Do NOT move the fan after it is fully installed. Movement of the fan unit may result in false triggers as a result of changing differential pressure and will require recalibration. See page 23 for recalibration steps.

POWERING AND SETUP

STEP 1
Plug your fan’s power cord into an AC power outlet to power your fan.

CLEANING

STEP 1
Unplug your fan to completely unpower it.
Then remove the motor box from the mounting flange. Refer to steps 1-2 on page 11 to learn how to remove the motor box.

STEP 2
Use a damp cloth to clear the impeller and fan blades of any dust and debris. Remove the wind circle in between the motor box and input flange.

STEP 3
Clear the stator blades of any dust and debris on the opposite end. Clean the area inside the output and exhaust flanges.

STEP 4
Secure the motor box onto the mounting flanges. Refer to steps 7-9 on page 14-15 to learn how to secure the motor box.

PROGRAMMING

1. MODE BUTTON
   Cycles through the controller’s modes: OFF, ON, and AUTO.

2. SPEED BUTTON
   Cycles through the levels to select a fan speed from 0-5. Pressing the speed button increases the fan speed in one unit increments.

OFF MODE
Your fan will not run while in this mode.

ON MODE
Your fan will actively run at the level set here. The ON Mode setting also serves as the maximum level the AUTO Mode will run at.

AUTO MODE
While in AUTO Mode, the fan will continuously monitor the environment for changes in pressure even while not in operation.
Once a pressure difference is detected for 5 seconds, the fan will be triggered to run.
The fan will run for 5 minutes, then pause for 5 seconds to test the atmospheric pressure. It will remain off if no difference is detected. Otherwise the fan will repeat the cycle as needed.
The fan speed must be adjusted in ON Mode before returning to AUTO Mode.

RECALIBRATION

UNINSTALLATION

STEP 1
Unplug your fan to completely unpower it.
If you need to relocate your fan, continue to step 2. Otherwise, skip to step 6.

STEP 2
Remove the tube from the differential pressure switch.
Remove the motor box and wind circle from the mounting flange.
Refer to steps 1-2 on page 11 to learn how to remove the motor box.

STEP 3
Loosen the duct clamps using a flathead screwdriver and remove the duct tubes from the flange.

STEP 4
Unscrew the wood screws with a screwdriver or drill to release the flange bracket from the wall.

STEP 5
Relocate your fan to a stable location free of obstruction.
Refer to steps 3-9 on pages 12-15 to learn how to mount your fan.

STEP 6
Plug your fan’s power cord into an AC power outlet to power your fan.
The base pressure should recalibrate once your fan is on.

FREQUENTLY ASKED QUESTIONS

Q: Can I mount this inline duct fan vertically or horizontally?
A: The automatic duct fan can be mounted in any orientation.

Q: Will I be able to hardwire this fan to my own controller or thermostat?
A: We do not recommend hardwiring or splicing our fan’s power wires. Such modifications may compromise electrical safety and will void this product’s warranty.

Q: Do I need to use a power converter if I’m outside the US?
A: This product’s voltage range is 100-240V AC. You may need a simple travel adapter to plug it into a foreign socket, or a power converter if your country uses a different voltage.

Q: I’m not getting enough airflow even after setting the fan speed to 5. What can I do?
A: Bends in ducting will reduce your fan’s CFM performance. To retain airflow, you may straighten the ducting and eliminate as many bends as possible.

Q: My fan isn’t triggering correctly. How do I fix this?
A: Check to see if your fan has been moved; this will affect its pressure detection. Refer to pages 23-25 for recalibration instructions.
