Startup Procedure
Place the ozonizer and power supply unit on a dry surface. Plug the 12V connector into the socket (2)
on the ozonizer. The ozonizer is equipped with a controller (potentiometer) (1), which allows continu-
ously variable adjustment of the ozone output. Plug the power supply unit into a socket.
The following guide values for setting the ozone volume apply: approx. 10 mg of ozone per hour for
26.4 gallons of marine water; approx. 5 mg of ozone per hour for 26.4 gallons of freshwater.
The LED (7) lights up when the ozonizer is in operation, though not when the output is zero. Above
zero, the LED (7) lights up and gets brighter as the output increases. At 100% output, the LED is
permanently lit up.
To determine the ozone requirements, we recommend measuring the redox potential with a Sander
redox measuring and regulating device, which switches the ozonizer on and off automatically depend-
ing on the set target value. For this purpose, the ozonizer should be set to full output.
When the device is new, we recommend gradually increasing the output over a period of roughly 14
days. This allows the living organisms in the water to slowly adjust to the improved water quality.
Cleaning and Maintaining the Ozonizer
To ensure that the ozonizer functions properly at all times, the ozone element must be cleaned regu-
larly. The ozone element has therefore been designed to be easily opened and cleaned. If the device
is in permanent use, we recommend checking the ozone element every three to six weeks for dirt and,
if necessary, cleaning it.
Cleaning procedure
• Before cleaning the ozonizer, set the ozone output to zero by turning the potentiometer,
and allow the device to run in this state for a few minutes. This ensures that any resid-
ual ozone is discharged from the ozone element.
• Switch off the ozonizer.
• Allow the ozone element (5) to cool down.
• Unplug the power supply unit.
• Remove the power plug (2) from the ozonizer.
• Remove the tubes from the tube connections.
• Unscrew the locking screws (6) for the ozone element (5) using a standard Phillips
screwdriver.
• Remove the cover for the ozone element (5).
• Clean the ceramic and titanium plate using a cloth and warm water (and standard
cream cleanser, if necessary); when doing so, also remove any dirt from the connect-
ing nipples.
• Allow the device to dry thoroughly.
Reassembling the device and switching it back on:
• Place the cover back on the ozone element (5), making sure that the sealing ring is
firmly seated in the groove.
• Reinsert the screws (6) partway and then tighten evenly.
• Reattach the tubes to the tube connections.
• Plug the 12V connector back into the power connection (2).
• Plug the wall power supply unit back into the socket.
• Use the potentiometer (1) to set the desired ozone output.
