Safety information

Electrical connection

Only connect the unit if the electrical data of the unit and the power supply match.
Only plug the unit into a correctly installed outlet. Ensure that the unit is fused for a rated fault current of max. 30 mA by means of a fault current protection device.
Extension cables and power distributors (e.g. outlet strips) must be suitable for outdoor use (splash-proof).
Protect open plugs and sockets from moisture.

Safe operation

Do not use the unit, if electrical lines or the housing are damaged.
If a power connection cable is damaged, have it replaced immediately by OASE, an authorized customer service or a qualified electrician to prevent electric shock.
Do not carry or pull the unit by its power cable.
Route lines so that they are protected from damage and nobody can trip over them.
Never make technical modifications to the unit.
Only carry out work on the unit that is described in this manual.
Only use original spare parts and accessories.
Should problems occur, please contact the authorized customer service or OASE.

	Never dispose of the unit with normal household waste.
	Read the operating instructions.

Installation and connection

Connecting the pressure hose

An optimum flow rate is achieved with a 50 mm hose diameter.
How to proceed:

Adapt the stepped hose adapter to the hose diameter.
Screw the stepped hose adapter onto the connection on the pressure side.
Connect the pressure hose to the stepped hose adapter. – Secure the pressure hose with a hose clip.

Automatic mode

When the water level rises, it lifts the float switch until the switch-on point is reached and the pump switches on.
When the water level drops, the float switch lowers until the switch-off point is reached and the pump switches off.
How to proceed:

Push the float switch cable into the cable clip.
– The shorter the cable between the float switch and the cable clip, the lower the switch-on point and the higher the switch-off point.

To ensure faultless function, ensure that the length of cable between the float switch and the cable clip is at least 100 mm long.

The minimum residual water height is only reached in manual mode.

Manual mode

The pump remains permanently switched on if the float switch is positioned vertically (cable hanging down).

NOTE

The pump can run dry in manual mode. Running the pump dry increases wear.

Switch off the pump when the minimum water level is reached.

Installing the pump

Install the pump in a vertical and stable position in the water.
If it needs to be lowered into a shaft, fasten a rope to the handle. Do not carry it by the power connection cable.
Install the pump so that it does not take in dirt particles with a size >40 mm, which would block the intake. Install the pump in a raised position if necessary.
Ensure that the float switch can always move freely.

Operation

WARNING

Serious injury or death from electric shock is possible.

Only operate the pump if no persons are in the water.
Disconnect all electrical devices in the water from the power supply before reaching into the water

NOTE

The pump is not suitable for long-term operation. Long-term operation will reduce the pump service life accordingly.

Switching on the unit

Insert the power plug into the outlet.
– The pump is ready for operation.
– The pump will start up as soon as the water level reaches the activation height.

Switching off the unit

Disconnect the power plug.
– When the pump is switched off, residual water in the hose may flow back and out of the pump intake.

Rinse the pump with clear water after use.

Maintenance and cleaning

NOTE

Do not use aggressive cleaning agents or chemical solutions. These agents can damage the housing, impair the function of the device and harm animals, plants and the environment.

Clean the unit with clean water and a soft brush or sponge wherever possible. Remove stubborn dirt with the aid of the recommended cleaning agents.

Clean the unit as required, but at least twice a year.

Recommended cleaning agent for removing stubborn limescale deposits:
– Pump cleaning agent PumpClean from OASE.
– Vinegar- and chlorine-free household cleaning agent.
After cleaning, thoroughly rinse all parts in clean water.

Storage/overwintering

The unit is not frost-proof and has to be removed and put into storage if freezing temperatures are expected.
How to correctly store the unit:

Thoroughly clean the unit and replace damaged components.
Store the unit in a dry and frost-free place.
Protect open plug connections from moisture and dirt.
Empty hoses and connections as much as possible

Troubleshooting

Malfunction	Possible cause	Remedy
The pump does not start	The power supply is interrupted	Plug in the power plug Check the fuse of the power outlet
The pump switches off after a short running period	The overload protection has switched the pump off due to overheating	Clean the intake opening and the pressure hose Allow the pump to cool down. The overload protection is auto- matically reset after cooling down
The pump is running but is not delivering, or the delivered quantity is insufficient	The pressure hose is blocked	Route the pressure hose with- out kinks Check the outlet and clean if necessary
	The intake opening is clogged	Clean the intake opening
	The pressure hose contains air	Bleed the pressure hose
	If applicable: The non-return valve is incorrectly fitted in the pressure hose or clogged	Fit the non-return valve cor- rectly Clean the non-return valve
	The impeller unit is faulty or worn	Contact OASE. The impeller unit may only be replaced by the OASE service.
