- The rain barrel pump is designed for pumping clear water only.
- The rain barrel pump is intended for pumping water from a rainwater butt or rainwater collecting tank. It is particularly suitable for watering plants in the garden.
It is not intended for delivering salt water, corrosive, easily flammable or explosive liquids (e.g. petrol, paraffin, thinners, etc.), faeces, oil, heating oil or foodstuffs.
■ This pump is not intended for commercial or industrial purposes.
■ The pump is not suitable for continuous operation, e.g. for watercourses in garden ponds. - Please note that the lubricants used in the pump may escape and cause contamination. Do not use the pump in garden ponds with fish stocks or valuable plants.
- The intended use also includes an operation following the operating instructions. Any use beyond these parameters (different media, applying force) or any changes (reconstruction, no original accessory) can lead to serious risks and is regarded as use that is contrary to the intended purpose.
Before first Use
Unpack the rain barrel pump and check all parts for any damage in transit. Keep packaging materials out of reach of children. There is risk of suffocation!
Charging the Battery
Before using the pump for the first time, fully charge the battery.
- Connect the battery charger (9) with a wall socket. The LED lights up green to indicate that power is on.
- Connect the battery (11) with the battery charger. The LED light up red to indicate that the battery is charged.

Pay attention to the maximum sub- mersion depth. Always make sure that the suction opening (8) is not blocked or obstructed during operation.
If necessary, place the pump on a brick or similar.
-
Run the irrigation hose for watering the plants. Observe the maximum delivery height.
-
Open the shut-off valve (1).

■ Make sure that water and moisture cannot get into the control unit.
■ Make sure that no particles bigger than approx. 1 mm are sucked into the pump.
■ Never pull the rain barrel pump by the cord.
- Avoid dry running of the pump! Dry running is operating the pump without water in the casing.
Using the Clamp
