Problem
Possible Cause
What To Do
No Power
Main Fuse
Check the main fuse next to the power
in port. If that is intact check the fuse
located on the main control board. This is
located behind the front panel.
Defective Control
If your unit has some power you will see
an indicator light flash when the power
button is pressed. The other option is
that the fuses are both ok and power is
present but not distributing it through the
system.
Only Back Power Is
On
Bad Transformer
Back power is on, but there is no power
on the control board. Check the 12 VAC
transformer located behind the bottom
right-hand corner on the front cover.
No Ozone
Old or Damaged Plates
Look in the side of the unit with the
vents. There should be a purple glow all
over the ozone plate. If there isn’t any
glow or it is very “spotty” then you will
need to replace them.
Order
C-3500 Ceramic Ozone Plates Set
to repair this issue.
Unit in Repeat Mode
When you select a repeat timer, the
unit will run its full timer function and
then the fan will continue to run until
the power is turned off. However, the
ozone plates will turn off until the next
ozonation cycle after the repeat timer.
No Plates Selected
Hit O
3
Plate Selection Button until the
desired amount of plates are selected.
