Regulating the suction intensity

The suction intensity can be regulated with the slide in the suction hose handle. Reducing the suction intensity can be
useful when the unit operated in the sludge suction mode draws in too much unwanted material, for instance, pebbles
that block the passage.

Unusual behaviour could be encountered during operation.
The unit heavily vibrates. Turn the unit off at the power switch (16) and on again after 20 seconds. If vibration per-
sists, probably either
– the tank is full (when operated as a wet vacuum cleaner, plug inserted),
– or the intake distributor, the drain or the foam filter is soiled.
In this case, clean and service the unit.
Vapour develops. No reason to worry. This is condensate released through the ventilation slots in the form of water
vapour. This effect is particularly encountered in cold weather.

Malfunction
Cause
Remedy
Vapour escapes from the unit
In cold weather, condensate forms in the unit,
which is released in the form of water vapour.
This is normal. No remedy necessary
The unit develops noise and/or heavy vibration
The tank is full
Drain tank
Intake distributor, drain or foam filter is soiled
Switch off the unit, wait 20 s, then switch on
again. If the malfunction reoccurs, clean the
unit.
The unit does not suck or its performance re-
duces
No mains voltage
Check mains voltage
Excessive height difference between water
level and unit
We recommend that the outlet height is slightly
above the water level
Both containers are full of water. The float bod-
ies seal completely
Drain the unit
Dirt plugs foam filters, the suction tube or the
suction hose
Remove dirt
The flap at the intake distributor is jammed or
soiled
Remove the intake distributor. Check the flap
seating (Fig. I, 4)
O ring at the inlet distributor not properly seated Check the O-ring seating (Fig. I, 4)
The flap at the outlet valve is jammed or soiled
Remove the drain hose. Check the flap seating
O ring at the inner tank not properly seated
Check the O-ring seating (Fig. I, 27)
Low suction capacity
Slide in the suction handle is open
Close the slide in the suction handle
Increased tube friction resistance
Keep the suction hose as short and flat as pos-
sible.
Suction depth too large. Due to the design, the
suction capacity reduces as from a suction
depth of 2 m
Reduce the suction depth
The container does not empty
The drain hose is kinked or was not laid with an
incline
Route the hose correctly. See Installation.
Drain hose or drain valve plugged with dirt
Remove dirt from the drain hose and the drain
valve
Poor unit switching behaviour between the con-
tainers, or no switch-over
Dirt film on the pistons after an extended down
time
Remove motor housing (G, 17). Start the
switching cycle manually by holding the motor
head overhead.
