19.2 Mounting Control Box
Mount the Control Box on top of the Air Handler.
Ɣ Be sure to mount the control box in the correct position indicated below or else it will come into contact
with the wiring holes of the air handler. Incorrect positioning will damage the wiring and affect the conduit
connection. A serious accident and malfunction may result.
Ɣ Make sure there are no shavings left inside the control box and air from drilling mounting holes for the
control box on the air handler. Shavings inside the control box will cause a serious accident and corrosion
to the heat exchanger.
