If airflow through the ozonizer drops below
75 litres per hour, ozone production will shut
down to prevent overheating. Please provide
sucient airflow to the ozonizer, removing any
blockages.
High temperature shutdown
If there is insucient ventilation for cooling or
insucient airflow, both combined with highlevel ozone production, the temperature in the
ozonizer may exceed its limit (70 °C). In this
event, the ozonizer will shut down to prevent
damage. Please provide sucient circulation of
air, in particular if the ozonizer is mounted in
a cabinet. The ozonizer will resume operation
once the temperature has dropped to be within
limits.

Specifications
⇒ Ozone output: 2000 milligrams per hour
⇒ Power supply: 100–240 volts AC (50/60 Hz)
⇒ Current consumption: 1,5 ampères
⇒ Operating voltage: 24 volts DC
Cleansing and maintenance
of the ozone generator
Humidity and dust contamination in the inlet air
cause ozone output to be reduced substantially.
With this in mind, the ozone generator has
been designed for easy maintenance and
cleansing.
With continuous operation, it is recommended
that the ozone generator be examined for
contamination about once every 3 to 6 weeks.
Before cleansing the ozonizer, please set the
ozone output to zero, but keep it running for a
few minutes. This will cause any residual ozone
to be removed from the ozone generator.

Determining and setting the
Operation with the Sander Redox Controller
appropriate ozone output
As a rough guide, use about 10 mg of ozone per
hour for every 100 liters of salt water, or about
5 mg of ozone per hour for every 100 liters of
fresh water.
When first using the ozonizer, we recommend
slowly increasing the ozone output over
a timespan of about 14 days, so that the
aquarium may gradually adjust to the enhanced
water quality.
For precise management of your setup’s ozone
requirement, we recommend using the ozonizer
in combination with a redox controller (Sander
redox potential detector and controller, part
number 7.1C). This device automatically turns
the ozonizer on or o, depending on a set value
for the redox potential.
To connect the redox controller, remove the
dummy plug from the 4-pin socket (8) on the
ozonizer, and replace it with the single plug on
the supplied redox controller adapter cable.
Then connect the two plugs on the other end of
the cable with the redox controller.
The actual value for the redox potential, as well
as the controller state, are displayed on the
redox controller’s top panel.
For further instructions, please refer to the
redox controller’s user guide.

Introduction
Intended use
Congratulations on your purchase of this
Sander quality product. We are confident
that you will be satisfied with this ozonizer.
Our many years of experience in aquarium
technology will benefit you in every detail.
Please familiarize yourself with the ozonizer
before using it for the first time — by reading
this user guide and paying particular attention
to the safety instructions. The ozonizer may
only be used for the specific purposes described
below. Please keep this user guide handy for
future reference, and include this guide when
handing the ozonizer over to a third party.
Package contents
Immediately aer unpacking, please make sure
the following items are included in the package,
and in flawless condition:
⇒ Ozonizer XT2000
⇒ Power supply
for aquariums and ponds
The ozonizer is a device for generating ozone
from air. It was developed specifically for use
with aquariums and ponds.
When operated with dry air, the ozonizer has
a rated output of 2000 milligrams (2 grams;
0,07 oz.) of ozone per hour. When using
ambient air (40 – 80 % humidity), ozone output
is reduced by about half.
Ozone must be released into the water at a
depth of no less than 20 cm (8 in).
We recommend using a skimmer, such as our
Helgoland series devices (for salt water), or
Fresh-Skim (for fresh water).
Other uses or device modifications are
considered non-intended use and may result
in injuries and/or damage to the ozonizer. The
manufacturer assumes no liability for damages
resulting from non-intended use.
The device is not intended for commercial use.

Safety instructions
The use of the ozonizer occurs at your
!
own risk.
The ozonizer may not come into
contact with water.
Free ozone is hazardous by inhalation.
To avoid release of excess ozone, it
must only be produced in the quantity required
by the application. The threshold limit value
(TLV, or maximum acceptable workplace
concentration) for ozone is 0.1 ppm (200 µg/
m³). However, the odour detection threshold
for ozone is 5 to 10 times lower (about
0.02 ppm). Detection of ozone odour is a sign
of excess ozone generation. Excess ozone (eg.
from a skimmer’s exhaust) must be released
into the outside air or fed into a residual ozone
absorber.
The ozonizer requires an airflow of no
less than 75 litres per hour. Reduced
airflow may cause the ozone generator to
overheat. The ozonizer will detect insucient
airflow and automatically shut o ozone
production to avoid overheating.
The ozonizer may be used by children
from age 8 — as well as by persons
with reduced physical, sensory or mental
capabilities, or insucient experience and
knowledge — only under supervision, or if
instructed on the safe use of the ozonizer,
and if they are aware of and understand the
potential hazards. Children may not play with
the ozonizer. Maintenance and cleansing tasks
may be performed by children only under
supervision.
Do not open the ozonizer’s casing.
Improper repair work or other
modifications may create considerable hazards.
In the event that your ozonizer requires
repair or other servicing, please contact your
specialist supplier or refer directly to the
manufacturer.
Do not operate the ozonizer if it is
damaged. Damaged ozonizers may
pose considerable hazards to the user.
The ozonizer may only be operated
with the original power supply unit
(item designation GS60A24-P1J, 24 volts,
2.5 ampères, 60 watts).
The surfaces of the ozone generator
may be hot. Before performing any
maintenance or cleansing tasks, please allow
the ozonizer to cool.

Air
There are two fastening clips on the reverse
side of the ozonizer. These may be used
for wall mount. It is recommended that the
ozonizer be mounted above the water level.
This will prevent water from flowing back into
the ozonizer, eg. in the event of a power failure.
Connect the air inlet (9) to an air pump using
6/8 mm tubing. Connect the ozone outlet (6)
to the airstone in the skimmer using ozoneresistant tubing.
If ozone production is turned o while the
ozonizer is still connected to the skimmer, the
air supply must remain on. This will prevent
water from entering the ozone generator.
Connecting the ozonizer for skimmer
operation with an injector
Connect the injector with the ozone outlet (6).
In this setup, airflow through the ozonizer is
provided automatically. To keep the inlet air
free of contaminants (including dust), it is
recommended to use a filter at the air inlet (9).
