Taking into operation
First turn the shut-off lever on the safety adapter to the ON position to open the three val-
18
ves. If the shut-off lever cannot be turned to the ON position, the safety adapter has not
been 昀椀tted correctly to the pump head. In that case, repeat step 17.
Press the suction aid 昀椀rmly several times until the 昀椀lter container automatically 昀椀lls with
19
water. As soon as the container is full the mains plug can be plugged in to begin operating
the 昀椀lter. Make sure that the nozzle tube (delivery side) is above the surface of the water during
the 昀椀lling process so that the device is optimally bled of air.
Attention:
may 昀椀ll with water. In that case, you can squeeze the 昀椀lled suction channel 昀椀rmly toget
her with your 昀椀ngers until the empty hose has 昀椀lled.
-
Then place the plug in the open end of the nozzle tube.
Regulating the 昀氀ow
To set the desired 昀椀ltering performance on the delivery side, turn the shut-off lever on the
20
safety adapter slowly in the OFF direction. The 昀氀oat in the indicator window shows the
actual 昀氀ow of water.
Indicator
The indicator provides continuous information about the volume of water 昀氀owing through
21
and signals any faults that may occur. If the 昀氀oat touches the red bar, the 昀椀lter is not per
forming to its full capacity and the 昀椀lter 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 昀椀lter 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 (pre昀椀lter)
Pull pre昀椀lter out of the container by the two handles and place in the pre昀椀lter
22
transportation dish. Empty pre昀椀lter and rinse out blue 昀椀lter pad thoroughly under lukewarm
running water until the water runs clear.
Renew blue 昀椀lter pad after the second or third cleaning (Order No. 2616802).
Tip:
-
Remove lattice screen from the container and check to see if the white 昀椀lter pad is very
dirty. Replace if necessary. The white 昀椀lter pad is for mechanical 昀椀ne 昀椀ltering. Since the dir
particles that cling to it cannot be completely washed out, the 昀椀lter pad may only be used
once. Use a new 昀椀lter pad (Order No. 2616802).
-
Replace pre昀椀lter in the 昀椀lter 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
