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)
