Adjusting the level detection device)
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 <50 °F (<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-clarifier switched
off for at least 36 hours so as not to impair their efficacy.
5.2
Adjusting the level detection device
A rise in the water level during operation indicates that the system is contaminated. The level detection
device signals possible soiling to the control system and the cleaning cycle is started.
The water level in the filter system is independent of the water level in the pond. The water level in the
filter system is dependent upon the circulation capacity. Therefore, it may be necessary to adjust the
level detection device.
The level detection device can be fitted in two positions.
►
Position 1: Suitable for circulation capacities greater than 2378 gph (9000 l/h) (factory default
setting).
►
Position 2: Suitable for circulation capacities smaller than 2378 gph (9000 l/h) and fewer automatic
cleaning intervals.
