Product Description
Bitron Eco 120W/180W/240W is a powerful UVC clarifier for controlling algae and harmful bacteria thanks to its
radiation output, water dwell time and thorough mixing action.
• The UVC lamps are switched on and off as required according to the algal growth rates. This allows it to achieve a
maximum result with minimum use of energy.
• The capacity can be individually adjusted using the control unit.
• Fully automatic bypass control ensures an ideal combination of flow rate and radiation output.
• The long dwell time of the water in the large volume casing increases the sterilising capacity.
• Suitable for fitting to OASE filter systems ProfiClear, BioTec 30 and BioTec Screenmatic.
• The cleaning rotor continuously removes soiling from the quartz glass.
• The 60 Watt Eco lamps are energy saving and have an operating life of 12000 hours.
• The electronic ballast is virtually lossless.
• It is not necessary to remove the quartz glass for changing the UVC lamps. The filter system can remain in operati-
on continuously.
Intended use
Bitron Eco 120W/180W/240W, in the following termed "unit", and all other parts from the delivery scope may be used
exclusively as follows:
• For cleaning garden ponds, swimming ponds, pools and aquariums.

Selecting the operating mode
To allow irradiation of algae and germs to suit the respective situation, it is possible to choose between four operating
modes.
The duration of irradiation is automatically controlled on the basis of the measured water temperature and the selected
operating mode. The ratio of the switch-on time to the switch-off time of the UVC lamps is dependent upon the operating mode. The higher the percentage value, the longer the switch-on time in relation to the switch-off time.
The UVC lamps are permanently switched on in the 100% operating mode.
Function Proceed as follows Note
Selecting the operating
mode
Press
several times until the desired
operating mode is reached.
− Switching sequence: 50 % – 75 % – 90 % – 100 % – Off.
− UVC lamps on: LED is lit blue:
− UVC lamps off: LED is lit green (energy-saving phase in Eco
mode).
− Select Eco mode 50 % if the water is only slightly soiled.
− Select Eco mode 75 % or 90 % if the water is more soiled.
− Select operating mode 100 % if the water is very soiled.
Procedure for green water:
− Start with operating mode 100 %. As soon as the desired result
is achieved, change to Eco mode 50 %. If the water becomes
green again, choose the next highest Eco mode until the desired result is achieved in the long term.
Procedure for clear water:
− Start with Eco mode 50 %. If the water starts to go green,
select the next highest Eco mode until the desired result is
achieved in the long term.

Display of different temperature values
when several OASE units with temperature display are used.
Toleranc e range of the tem perature measurement
The temperature probes are precise to ± 1 °C. If other
units with temperature display are operated, the
displayed temperature values may differ from one
another by up to 2 °C.
− Recommendation: The arithmetic mean of all
displayed values produces a useful approximation of
the actual temperature.
− Greater deviations are possible if the units are
exposed to direct sunlight. For this reason, ensure
that the unit is installed such that it is protected from
direct sunlight.

Cleaning the quartz glass
Attention! Breakable glass.
Possible consequences: Injury to your hands caused by cuts.
Protective measures: Handle the quartz glass and UVC lamp with care.
Note!
If the water flow is suddenly interrupted downstream of the outlet (e.g. with a slide valve), this can lead to a
brief increase of pressure of more than 1 bar (water hammer).
Possible consequences: The unit may be damaged.
Protective measures:
• Switching off: First switch off the pump, then close the slide valve. If the unit is operated in a filter system,
first take the filter system out of operation.
• Switching on: First open the slide valve, then switch on the pump. If the unit is operated in a filter system,
start up the filter system last.
• Install the slide valve upstream of the inlet.
