Operation
Abnormalities
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.
Remedy of faults
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 tank is full Drain tank The unit develops noise and/or heavy vibration
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.
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
bodies 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. H, 25)
O ring at the inlet distributor not properly seated
Check the O-ring seating (Fig. H, 25)
The flap at the outlet valve is jammed or soiled Remove the drain hose. Check the flap seating
O ring at the distributor unit not properly seated
Check the O-ring seating (Fig. I, 28)
The unit does not suck or its performance
reduces
O ring at the inner tank not properly seated
Check the O-ring seating (Fig. I, 27)
Increased tube friction resistance Keep the suction hose as short and flat as
possible.
Low suction capacity
Suction depth too large. Due to the design, the
suction capacity reduces as from a suction
depth of 6.5 ft (2 m)
Reduce the suction depth
The drain hose is kinked or was not laid with an
incline
Route the hose correctly. See Installation. The container does not empty
Drain hose or drain valve plugged with dirt Remove dirt from the drain hose and the drain
valve
Poor unit switching behaviour between the
containers, 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.
