Unit is not connected to power 

source, or is connected to 

improper power source

Refer to input power 

requirements on pg. 12, and 

Figure 1 on pg. 14 for proper 

electrical connections.

Electrical short circuit

Visually inspect unit and check 

for loose connections. Inspect 

printed circuit board (PCB) for 

burn marks. Inspect HV wire from 

PCB to CD cell for disconnection 

or burn marks. Repair any and 

all problems prior to placing 

unit back into service, or contact 

factory for service.

Unit is connected to improper 

power source

Refer to pg. 12 to ensure that 

unit is plugged into proper 

voltage outlet.

Unit turns on, 

but no ozone 

output

Frequency driver is defective

Replace PCB board.

Frequency driver high voltage 

lead not connected to ozone 

cell

Connect red flag terminal to CD 

cell spade connection.

Water has been allowed to 

back up into the CD cell and 

has caused a direct short

Dry CD cell using drying 

procedure on pg. 10. Replace 

CD cell.

Cell is plugged with build-up 

of nitrous byproducts and 

particulate matter. Usually 

caused by the lack of proper 

air preparation

Refer to section 5.1 on pg. 10 to 

clean CD cell. Replace CD cell.
