Oase Bitron Eco Serie Puesta En Marcha página 24

Without bypass
• OASE recommends closing the bypass in the following situations:
– Acute problems such as disease or turbidity due to a build-up of bacteria.
– Low flow rates:
Bitron Eco 120 W: < 10000 l/h
Bitron Eco 180 W: < 13000 l/h
Bitron Eco 240 W: < 15000 l/h
How to proceed:
 H
1. Turn the bypass holder counterclockwise until it makes an audible click and remove it from the
outlet.
2. Pull the bypass membrane out of the bypass holder and fit the bypass closure onto the bypass
holder.
– The bypass closure can only be fitted onto the bypass holder in one position.
3. Insert the bypass holder into the outlet and turn it clockwise until it makes an audible click.
– The bypass holder is locked in place.
4. Insert the outlets with flat seals through the holes in the container wall into the distributor.
5. Screw the distributor nuts onto the outlets and hand tighten.
6. Connect the Bitron to the filter pump. (→ Connecting the inlet)
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.
