9. The Control and Use of Air Curtain
1. Installation of the magnetic door switch (Picture 6-1, 6-2). The air curtain can be controlled by this
switch.
Part A goes on the door frame and Part B goes onto the door itself. As long as the magnets in both parts
work when close to each other when the door is closed, the magnetic door switch has been properly
installed. When the door is closed and both parts are close to each other, the air curtain will not be active
and will be off. (Picture 6-1) Once the door is open and both parts are no longer near each other, the air
curtain gets activated and will turn on. (Picture 6-2)

circuit (Picture 7-1, 7-2); once you have pressed the ON button please press LO or HI, then after
obtaining the appropriate air speed, press the OFF button to stop.

mentioned above, the door switch allows the air curtain to turn on whenever the door opens which is
convenient for when the door is normally kept closed. The remote can only turn the air curtain on when
the door is open and Part A and B of the magnetic door switch are no longer touching. Once the door is
open, and the air curtain is off, you can click the ON button on the remote and the air curtain will be
activated to the setting of either HI or LO. If you wish to go back to having the air curtain controlled by the
magnetic door switch, just go ahead and turn it off using the remote and turn it back on using the buttons
directly on the air curtain itself as mentioned in #2 of section 9.
