Air curtains are widely installed at the entrances of supermarket, theater, meeting room, hotel,
office room, storeroom etc. They can reduce penetration of insects, dust, and unconditioned air
into a conditioned space by forcing an air stream over the entire entrance to create a comfortable
environment for you.

WIRING DIAGRAM
6.OPTIONAL MAGNETIC SWITCH INSTALLATION
This air curtain comes with a magnetic door switch, contact seller or Awoco if you are missing a
magnetic switch. The dedicated 2 wires (Yellow) are to connect to the magnetic switch.
Note: Keep the 2 wires connected (closed) if the magnetic switch is not used.
Connect the magnetic door switch:
Cut the nut off the 2 yellow wires, and connect the 2 yellow wires to the magnetic switch one by one. Use the
black electrical tape to seal the connection. Don’t place the magnetic switch close to existing alarm sensors.

6
Mount the 2 pieces magnetic switch to the door/window edge and frame; keep them close when the
door/window is closed. If needed, apply a metal “Z” bracket to raise the magnet to the same position. Note: Do
NOT use big screws!!! Oversized screws will damage the magnetic switch internally.
Note: Don’t place the magnetic switch close to existing alarm sensors. The existing alarm sensor
magnet will interfere with this magnetic door sensor.

7.TROUBLESHOOTINGS
Failure symptom
Possible causes
Troubleshoot and solution
Fan blower is
broken
Damaged during
shipment
If the fan blower is broken and your purchase is from
an authorized seller, contactAwoco to get a fan wheel
replacement.
Fan blower is stuck
or generates
strange noise
The fan blower is
damaged during
shipment
ContactAwoco for instruction on changing the fan
blowers.
The magnetic
switch isn’t function
correctly
sometimes.
The magnetic
switch is defective
or close to an
alarm sensor
Don’t place the magnetic switch close to an alarm
sensor. The alarm sensor magnet will interfere with it.
Remove the magnetic switch connection and test if
the magnetic switch is defective.
The air curtain
doesn’t turn on.
(Make sure your
power outlet is
120V before
plugging in. Some
old air curtains
might use 240V)
The magnetic
switch is defective
or loosen
connection
Remove the magnetic switch connection, directly
connect the 2 yellow wires together then test the air
curtain. 80% of the failure is due to the magnetic
switch setup. Don’t use oversize screws, and make
sure the connection is secure.
Check if the front
switch is function
After a long period of time, the L/Off/H (or On/Off)
switch might be burnt out. Please test the switch.
Circuit board
failure or no power
to circuit board
Toggle the magnetic switch and the front switch; hear
if “Tic-Tac” sounds from the relay on the circuit board.
No sound means no power to motors.
Motor rotates slowly
Startup capacitor
is not connected
securely or
defective
Check if the 2 yellow/orange wires securely connect
to the capacitor under the motor. Remove the motor to
get access if needed.
After above
troubleshoot
processes, motor
still doesn’t turn on
Motor is defective
This chance is very low but it might happen.
Use Ohm meter to measure the continuity between
motor’s black wire and the white wire to check if it is
open. Open means defective.
Note: This air curtain requires technique/skills to open the cover to service, and changing
the blower requires some special tools. If you are a technician, please contact Awoco
technical support for repair instructions. Return/exchange is always the option.
