Commissioning/start-up
N O T E
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 da-
maged.
• 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.
N O T E
New filters take approx. 3 to 4 weeks before the bacteria in the unit 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 starter, medicines or pond water treatments, leave the UVC clarifying unit switched off for
at least 36 hours so as not to impair their efficacy.
