- Monthly inspection: Remove deposits in the upstream area of filter chamber No. 15. Remove any major residues. Clean
residues from filter cartridge. Check that the hose connector bush fits tightly in air intake No 27a.
- Six-monthly maintenance: Change the G4 filter mat No 34. If the filter mat becomes clogged, the turbine can be irreparably
damaged through lack of cool air.
- The eco may only be used for dry extraction and not in the open air. The unit must be, of course, be serviced and repaired as
necessary. See also Section 10 / page 5 “Troubleshooting checklist”.
Prevention of mechanical hazards: All moving parts of the machine (e.g. turbine) which are potential hazards are covered by
means of permanent, fixed, protective covers which can only be removed with the use of tools.
Prevention of electrical hazards: All parts of the machine which carry an electric current are insulated by means of
permanent, fixed protective devices which can only be removed with the use of tools.
Other risks: If the above mentions instructions are not observed, there is acute danger for the operating personnel.
7. Filter
7.1 Air flow, filter arrangement
The extracted particles (e.g. dust, flower, powder, chips, granulate) are drawn via air intake No. 27a into the synthetic filter No.
42. The synthetic filter No. 42 serves to relieve filter cartridge No.14 and absorbs the chips and a large portion of the dust.
However, fine dust passes through the synthetic filter. The air flow carries the fine dust to filter cartridge. Here, it is deposited on
the pleated surface of the filter cartridge (air intake area No. 15).
7.2 Red indicator light No. 5
The red indicator light comes on when the performance of the extractor drops significantly at a medium potentiometer setting (5-
7 on the scale). When the red light comes on, the EC blower cuts out immediately. In order to briefly continue to operate the
turbine until the indicator light comes on again, a RESET can be carried out as follows:
1. Set main switch NO.1 to position “0”
2. Set the changeover switch No. 2 position “0”
3. Set main switch No. 1 to position “1”
4. Set the changeover switch No. 2 to position “1” (with remote control via SUB9 port) or position “2” (without remote
control) depending on the function selected.
- Important: both filters must now be checked (see 7.3 and 7.4), because
•the synthetic filter may be full
•there may be heavy deposits on the filter cartridge
•the synthetic filter may be full and there may be heavy deposits on the filter cartridge
7.3 Synthetic filter: filter saturation, visual inspection, changing
The synthetic filter is a disposable filter and should be changed when it is ¾ full. Depending on the application and the amount
and specification of material to be extracted, it may be necessary to carry this out every day or not for several weeks. The
condition of the synthetic filter can be determined by as follows:
Visual inspection: Release clasp No. 26b, remove filter chamber cover No. 24. The level of the synthetic filter can be seen
through opening No. 35 or feeling by hand. When replacing the filter chamber cover, make sure that both pins No. 23 engage in
holes No. 12 and that both guide lugs No. 25 fit onto pins No.17. Fasten the cover with the clasp. During visual inspection, the
extraction hose must be removed from the air intake.
Changing synthetic filter: Remove the filter chamber cover. Remove Holder of synthetic filter No. 18 complete with synthetic
filter No. 42 from the filter chamber. Pull the synthetic filter out of the slot No. 19 (see also direction of arrow in Fig. 4) and close
synthetic filter with the paper sealing lug No. 44 (turn it down). Insert new synthetic filter Note: tab No. 43 must remain
protruding from slot No. 19 – see Fig. 3). Insert the holder with the synthetic filter. Replace the filter chamber cover as described
under “Visual inspection” and fasten same.
7.4 Filter cartridge: filter saturation, visual inspection, cleaning, removing and replacing
Filter cartridge No. 14 is upstream of the turbine and fastened onto retaining bolt No. 13 by means of nut No. 13b (with silicone
seal and washer). The filter cartridge (category M filter material) is designed for fine dust.
Visual inspection: When the filter level light described in 7.2 comes on, the filter cartridge must be checked. Remove filter
chamber cover (as described in 7.3). The filter cartridge is pleated. Check for dust deposits between the pleats and for dust
accumulation on the floor on the filter chamber. If this is the case, the filter cartridge must be cleaned.
Cleaning/removing and replacing the filter: Use a size 10 open-ended spanner to undo M6 No. 13b. Put a sufficiently large
plastic bag (e.g. 30 or 50 litre rubbish back over the filter cartridge). Pull out the filter cartridge with the plastic bag over the
threaded bar (retaining bolt), No. 13a. Close the plastic bag around the filter cartridge. The fine dust can now be shaken out of
the pleats by shaking the filter cartridge several times. Replace the filter cartridge over the threaded bar and position it over
cantering plate No. 38. Tighten the silicone seal, washer and nut.
Fasten filter chamber cover (as described in 7.3)
The filter cartridge can be re-used several times. After a long service life, the cartridge must be replaced by a new one. This is
because the pores of the filter material gradually seal up over time and can no longer be cleaned by shaking. It is necessary to
replace the (shaken) filter cartridge if the red light comes on again after a fairly short time.
