Gravity fed system
Order of steps for start-up
How to proceed:
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 on
the display of the control system.
Moving Bed filter chamber
The Moving Bed filter chamber contains three 5.3-gal bags (20 l) of Hel-X 13 biomedia (15.9 gal (60 l)).
Optionally 22.5 gal (85 l) can also be used (supplementary kit order no.: 42904).
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 colonized. Uncolonized
Hex-X biomedia tend to float more.
When using the supplementary kit, add the biomedia gradually. Recommendation: max. 1.3 gal
(5 l) per week.
Filter drum
5. Manually turn the filter drum by 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. Open the slide valve at the inlet and outlet, if applicable, to fill the filter system with water.
8. Fill the pond until the maximum water level is reached.
9. Check the water level in the Drum Filter Module. Refer to the adhesive label with level markings on
the inside wall of the container.
– Ideal water level: 4.3 in (110 mm) below the top edge of the container
– Permissible tolerance: -0.8 in (-20 mm), i.e. 5.1 in (130 mm) below the top edge of the container.
– Correct the installation if the minimum water level is not reached.
10. Fit the container cover.
Switching on the control system and additional units, checking the pipes
11. Switch on the control system and perform any necessary adjustments. (→ Operation)
12. Switch on the filter pump and UVC clarifier (if applicable).
– Ensure that the water is returned to the pond via the return pipe.
13. Check all pipes, hoses and their connections for leaks.
– Expansion seals may leak initially until they have fully expanded on contact with water.
14. Adjust the level detection device, if necessary. (→ Setting 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 clarifying
unit switched off for at least 36 hours so as not to impair their efficacy.
