Regulating The Suction Intensity - Oase PondoVac 4 Instrucciones De Uso

Operation as a sludge suction unit (Fig. B, E)
Note: When the unit is used as a sludge suction unit, the waste water is directly drained through the drain
hose (Fig. B, 3). The water is not collected in the container.
How to proceed:
– 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
Note: When using the unit as a wet vacuum cleaner, the waste water is collected in the container. A maximum of 10 l
of fluid can be taken in.
How to proceed:
– 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).
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 resid-
ual water.
Note: Always work slowly, performing smooth, uniform movements. This largely prevents sediments from being swirled
up.
Commissioning/start-up
Attention! Never operate the unit without foam filter (Fig. H, 22) or float body! Both are fitted when delivered. Never
vacuum dust or dirt!
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.
Operation

Regulating the suction intensity

I
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.
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.
