Step 5 – Remove control module & electrical cord set
If your application as it relates to step #3 is plugged directly into an outlet on the
top of the hood, unplug it at this time.
Standing on a ladder, remove the left screw only on the top of the control module.
***Be prepared that the control module will be completely free when you remove
the other screw.***
Next remove the screw to the right and hold the module up so it does not fall
forward.
Now let the control module move forward slightly and then lift it straight up to
free it from the lower bracket of the front mounting plate.
Once you have it off the bracket, have your helper hold it, allowing you to be free
to remove the final connections:
 Ethernet cable (if applicable)
 Power cord (depending on your application)
Unplug the ethernet connection and remove it from the controller. If your
controller is not hardwired into the electrical system and plugged directly into an
outlet on the top left side of the hood you may now move on to the next step.
Otherwise if your controller is hardwired directly into your electrical system then
you must continue with the rest of this step.
***Again at this point make sure all power supplied to the hood controller is
turned off at the breaker.***
Next, disconnect the quick connect to remove the control module from the inlet
power electric cord set.
Step 6 – Snake all remaining wires up through hood
Now snake the wires that you disconnected from step #4 through the hood as
needed so that you can completely remove the controller from the super structure.
Once you have the control module free, have your helper place it on a table so
that it faces down on a piece of cardboard.
