The UVC lamps can be switched on and off as required based on the algal growth rates. This permits maximum results with minimum use of energy. The power level can be adjusted individually 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 high-volume casing increases the sterilising capacity. Suitable for use with 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 to change the UVC lamps. The filter system is suitable for continuous operation. Symbols on the unit Read the operating instructions.

Commissioning/start-up NOTE The unit may be damaged, if the water flow is suddenly interrupted downstream of the outlet (e.g. by a slide valve). The sudden interruption can cause a temporary pressure increase of over 1 bar (hydraulic shock). 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. As an alternative, install the slide valve upstream of the inlet. It takes approx. 3 to 4 weeks before the micro-organisms in new filters are fully established. During this time – or at a water temperature of <10 °C – the filter may overflow. In this case the filter does not need to be cleaned. When using filter starters, medicines or pond water treatments, leave the UVC pre-clari- fier switched off for at least 36 hours so as not to impair their efficacy. On delivery, the unit is turned off. OF is indicated on the display. In new pond installations, wait at least 36 hours after set-up to start UV irradiation to en- sure that a stable pond biology can develop as quickly as possible. Order of starting up steps Switch on the pump. Check all connections for leaks. Connect the unit to the power supply. – The unit switches on with the last selected operating mode. – Switch on the unit if necessary. (→ Switching ON/OFF) Select the operating mode. – A garden pond is subject to a number of different influencing factors that encourage algae growth (e.g. direct sunlight, nutrient contamination, natural planting). Therefore the suita- ble Eco mode can only be individually determined. – Observe the information regarding the selection of a suitable operating mode. (→ Selecting the operating mode)40 Operation Switching ON/OFF Function Proceed as follows Note Switching on Press . The operating mode "50 %" is active. The display indicates the current water temper- ature. The status display of the UVC lamps is lit. Switching off Press several times until the UVC lamps turn off after operating mode "100 %". Switching sequence: 50 % – 75 % – 90 % – 100 % – Off. The display indicates OF. In the event of an error, the corresponding error message is displayed. Selecting the operating mode It is possible to choose from four operating modes to match irradiation of algae and germs to the requirements of the situation. The duration of irradiation is automatically controlled on the basis of the measured water tem- perature 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. In 100% operating mode, the UVC lamps are permanently switched on. Function Proceed as follows Note Selecting the oper- ating mode Press until you reach the desired operating mode. 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. How to proceed if the water is green: 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 higher Eco mode until you achieve the desired result permanently. How to proceed if the water is clear: Start with Eco mode 50 %. If the water starts to go green, select the next higher Eco mode until you achieve the desired result permanently.EN
