During commissioning, Er88 is indicated in the display of the control system,
► for as long as the final water level is not reached in the filter container,
► when the pump status detection is not correctly set.
If the filter system operates correctly, the system message will reset automatically.

Order of starting up steps
How to proceed:
E
1. Close the slide valve for the dirt outlet at the bottom of the container.
2. Check that the entire filter system (pipes and hoses) is complete.
3. Remove the container cover.
– The filter drum is stopped for safety reasons if the filter cover is lifted and Er11 is indicated in the
display of the control system.
Moving bed filter chamber
The moving bed filter chamber contains three 20 l sacks of Hel-X 13 biomedia (60 l). Optionally, 80 l can
be used (supplementary kit Order No.: 43383).
4. Tip the Hel-X biomedia from the bags into the moving bed filter chamber.
– Ensure that the Hel-X biomedia can move around freely in the container.
– It can take several weeks for the Hel-X biomedia to become completely colonised. Uncolonised
Hex-X biomedia tend to float more.
When using the supplementary kit, add the biomedia gradually. We recommend adding max. 5 l per
week.
Filter drum
5. Manually turn the filter drum for one whole rotation to ensure unobstructed movement.
6. Fill the filter with water until the rinsing pump is submerged (dry run protection of the rinsing pump).
7. Fit the container cover.
Switching on the control system and additional units, checking the pipes
8. Switch on the control system and perform any necessary adjustments. (→ Operation)
9. Switch on the filter pump and UVC clarifier (if applicable).
– Ensure that the water is returned to the pond via the return pipe.
10. Check all pipes, hoses and their connections for leaks.
– Expansion seals may leak initially until they have fully expanded on contact with water.
11. Adjust the level detection device, if necessary. (→ Setting the level detection device)
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 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.
