−Electrical installations must meet the national regulations and may only be carried out by a qualified electrician.
−A person is regarded as a qualified electrician, if, due to his/her vocational education, knowledge and experience, he
or she is capable of and authorised to judge and carry out the work commissioned to him/her. Working as a qualified
person also includes the recognition of possible hazards and the adherence to the pertinent regional and national
standards, rules and regulations.
−For your own safety, please consult a qualified electrician.
−The unit may only be connected when the electrical data of the unit and the power supply coincide. The unit data is
to be found on the unit type plate or on the packaging, or in this manual.
−Ensure that the unit is fused for a rated fault current of max. 30 mA by means of a fault current protection device.

−Never operate the unit if either the electrical cables or the housing are defective!
−Do not carry or pull the unit by its electrical cable.
−Route all cables such that damage is excluded and nobody can trip over them.
−Never open the unit housing or its attendant components, unless this is explicitly required in the operating
instructions.
−Only use original spare parts and accessories for the unit.
−Never carry out technical modifications to the unit.
−Only have repairs carried out by customer service points authorised by OASE.

Installation

Preparation (Fig. C, D, E):
−Fit the wheels (11) on the housing.
−Bring the transport brace (12) into the desired position. For this purpose, loosen and retighten the hand screw (13).
−Fit the intake distributor (4) into the inlet (14) by performing a plug-turn movement (bayonet closure).
−Connect the suction hose (2) to the intake distributor (4).
−Fit the extension tube (Fig. A, 6, 7) at the hand-held nozzle of the tube (2). The transparent tube (6) allows a flow
control to be able to detect blockages earlier.
−Slide on the tool (9, 10) appropriate for the task.
Note: The higher the number of tubes used, the higher the tube frictional resistance. This leads to a reduction of the
suction capacity.
Operation as a sludge suction unit (Fig. B, E)
Attention! Never operate the unit without foam filter (Fig. I, 22) or float body! Both are fitted when delivered.
−Place the unit at a minimum distance of 2 m from the water.
−Route the drain hose (3) with a slight gravity: Places the unit slightly higher. Ensure a safe and stable position.
Ensure that the drain opening (15) is above the water level.
−Plug the drain hose (3) into the drain opening (15) of the collection container.
−Ensure that the hose lies straight: Avoid kinks or bends caused by unevenness of the ground. Allow unrestricted
draining of the water, which has to be disposed of in accordance with the local conditions.
Note: When you pull the dirt catcher bag (Fig. A, 8) over the free end of the drain hose (3), you can return the water,
then free from coarse particles, such as dead leaves or algae, into the pond. As an alternative, the removed pond
sludge can be used as plant fertiliser. In this case, lay the drain hose directly on a plant bed. Otherwise dispose of in
accordance with the local conditions.
Use as a wet vacuum cleaner
Attention! Never operate the unit without foam filter (Fig. I, 22) or float body! Never vacuum dust or dirt!
−Place the unit at a minimum distance of 2 m from the water (Fig. B).
−Seal the drain opening (15) of the collection container by means of the plug (Fig. C, 5).
Note: A maximal of 10 l of fluid can be taken in.

Use of the tools (Fig. A, 9, 10):
Universal tool (a): To remove pond sludge without taking in the pond gravel.
Thread algae tool (b): For the separation and removal of thread algae.
Bristle tool (c): For the removal of stubborn soiling.
Large tool (10): For cleaning large, level surfaces.
Wet suction tool (d): Only to be used when operating the unit as a wet vacuum cleaner to remove soiled water or
residual water.
Note: Always work slowly, performing smooth, uniform movements. This largely prevents sediments from being swirled
up.

Connect the unit to the power supply. The unit is equipped with a power switch (Fig. F, 16):
Position I: Automatic mode. Continuous operation.
Position 0: The unit is switched off.
Note: When the unit is used as a sludge suction unit, the waste water is directly drained through the drain ho-
se (Fig. E, 3). The water is not collected in the container.

Operation

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 tank is full Drain tankThe 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 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.
