Taking into operation

18
First turn the shut-off lever on the safety adapter to the ON position to open the three val-
ves. If the shut-off lever cannot be turned to the ON position, the safety adapter has not
been fitted correctly to the pump head. In that case, repeat step 17.
19
Press the suction aid firmly several times until the filter container automatically fills with
water. As soon as the container is full the mains plug can be plugged in to begin operating
the filter. Make sure that the nozzle tube (delivery side) is above the surface of the water during
the filling process so that the device is optimally bled of air.
Attention:
may fill with water. In that case, you can squeeze the filled suction channel firmly toget
her with your fingers until the empty hose has filled.
- Then place the plug in the open end of the nozzle tube.
Regulating the flow
20
To set the desired filtering performance on the delivery side, turn the shut-off lever on the
safety adapter slowly in the OFF direction. The float in the indicator window shows the
actual flow of water.
Indicator
21
The indicator provides continuous information about the volume of water flowing through
and signals any faults that may occur. If the float touches the red bar, the filter is not per
forming to its full capacity and the filter system must be checked (see what to do if...,
pages 17-19).

Service and maintenance

- First turn the shut-off lever on the safety adapter to the OFF position
(see step 20). Pull out plug from mains. Remove safety adapter (see step 6).
- Tilt the filter slightly forward, using the recessed grips and pull out of the cabinet on the
castors. Open all four closing clips and remove the pump head.
Interim cleaning (prefilter)
22
Pull prefilter out of the container by the two handles and place in the prefilter
transportation dish. Empty prefilter and rinse out blue filter pad thoroughly under lukewarm
running water until the water runs clear.
Tip:
Renew blue filter pad after the second or third cleaning (Order No. 2616802).
- Remove lattice screen from the container and check to see if the white filter pad is very
dirty. Replace if necessary. The white filter pad is for mechanical fine filtering. Since the dir
particles that cling to it cannot be completely washed out, the filter pad may only be used
once. Use a new filter pad (Order No. 2616802).
- Replace prefilter in the filter container. Check seals on the pump head and the upper edge
of the container and clean off any soiling. Replace pump head. Close all four closure clips.
Reinsert safety adapter (see step 17).
- Turn shut-off lever to the ON position (see step 18) and press suction aid several times
(see step 19). Then take the device into operation by plugging it into the mains.
Depending on the way the hoses are laid, initially only one of the two hoses
