IMPORTANT SAFEGUARDS
This symbol indicates important safety information. The accompanying illustration shows
a warning: "Be careful of electric shock."
Always unplug the fan before moving it to a different location.
Do not use the fan in or near a window. Exposure to rain may cause electrical hazards.
Do not damage, modify, excessively bend, pull, bind or place heavy objects on the power
cord. Doing so may cause electric leakage, fire, or electric shock.
If the fan will not be used for an extended period, unplug it from the power outlet.
If the power cord is damaged, do not attempt to repair it yourself.
Contact your local service center or a qualified electrician for replacement to avoid risk of
injury or damage.
Never insert fingers, pencils, or any other objects through the safety guard while the fan
is operating.
Do not attempt to disassemble, repair, or modify the unit while it is in operation. This can
lead to electric shock, fire, or personal injury.
Failure to follow these instructions may result in electric shock, fire, personal injury, or
damage to the unit.
When unplugging the fan, always hold the plug—do not pull the cord. Pulling the cord
may damage it and cause electric shock or fire.
Always disconnect the power before cleaning the fan.
WARNING
Use only with a power supply that matches the rated voltage. Using an incompatible
power source may cause fire or electric shock.
Stop using the fan immediately if you notice smoke, unusual odors, abnormal motor
sounds, or any other malfunction. Continued use may result in fire or electric shock.

PRODUCT OVERVIEW
Heavy-Duty Build Next-Gen DC Motor Dual-Ball Bearings
Telescopic Wall-Fit Design
Two-Way AirflowSmart Controller
This model improves ventilation between rooms through wall fans, making it ideal for offices,
workshops, recreation rooms, laundry rooms, bedrooms, guest rooms, and other areas that
might not otherwise have access to proper airflow.
Application
Pwm Control Fans
The system utilizes high-performance DC motors controlled by PWM (Pulse Width Modulation).
This technology allows the dual fans to operate smoothly at extremely low RPM speeds without
generating motor or electromagnetic noise. Additionally, the fans feature blades designed with
a high static pressure rating, making them perfect for applications where airflow is restricted,
such as through ductwork. The motor housing allows the fan system to be mounted either
horizontally or vertically.

INSTALLATION GUIDE
From the center point, measure the distance
to the end of the wall (X) and the height to
the floor (Y).
Keep these measurements for Step 7.
Step 2
Drill the mounting holes into the wall.
Cut the circular outline to create the opening using a saw for best results.
Step 3
Step 1
Choose a mounting location free of
obstructions (e.g., studs, waterlines,
electrical cords, etc.). Ensure the wall is
3.5 to 6.2 inches thick.
Use the rear faceplate stencil to mark
the center point, mounting points, and
the circular outline.
- 05 -
X
Y
Step 8
Place the front faceplate stencil over
the center point, then mark the mounting
points and circular outline.
Step 9
Drill the mounting holes into the wall.
Cut the circular outline to create the opening.
Again, using a saw is recommended.
Step 4
Insert the included anchors into the
mounting holes.
Step 5
Position the rear faceplate into the circular
cutout, ensuring the mounting holes align.
Step 6
Secure the rear faceplate by drilling the
screws into the anchors.
Step 7
On the opposite side of the wall, mark the
center point using the length (X) and height
(Y) from Step 2.
- 06 -
X
Y
Step 10
Insert the included anchors into the mounting holes.
Step 11
Insert the front faceplate into the circular
cutout, ensuring the mounting holes align.
The cylinder should easily slide into the rear
faceplate's cylinder.
Step 12
Route the power cord through the opening
at the lower right corner to ensure the front
faceplate is flush against the wall.
Step 13
Secure the front faceplate by drilling the
screws into the anchors.
Step 14
Insert the power adapter cable into the unit's
power socket. Then, plug the AC power cord
into a wall outlet to power the fan.
