Safety measures
- Caution! It may only be used in garden ponds and in their protection area if the electrical installations
have been set up to comply with the code's requirements. Please contact an electrician.
- Before use: Check whether mains connection and plug are intact.
- Mains voltage and type of current have to correspond to the data on the type plate.
- The pump has to be connected to a regular safety plug socket through a residual current
device (RCD, 30 mA).
- The connection box should be located in a water-protected area. It should be at least 2 m away from the
edge of the pond (see fi g.1).
- Keep the plug dry!
- Pull out mains plug before starting to work on the pump, fountain or pond. It is not allowed to
run the pump when people are inside the water (disconnect the pump)!
- Important! If the mains connection or the motor housing is damaged, the pump cannot be used
anymore. It cannot be repaired since the connection is cast into the motor housing.
- Never hang up or transport the pump by the cable!
- Operate the pump only when it is immersed in water!
Start-up (see fi g. 1, 4 + 6)
Important! Do not let the pump run dry. This could cause damage to the appliance.
- Immerse the pump completely in your pond. This causes the pump body to be fi lled with water.
- A minimum water depth of 12 cm is required for underwater operation to avoid the pump taking in air.
- The maximum depth for submerged operation of the
pump is 2 m!
2 m
- The water temperature should not exceed 35°C.
- Do not let the pump freeze in the wintertime.
- The pump is switched on by putting the plug in the socket.
- To prevent the pump becoming unnecessarily dirty, place it above the mud in your pond, in a fi rm and
horizontal position (on a brick)!
- A range of accessories may be fi tted onto the threaded connection of the pump.
- Running in conjunction with fountain jets, the pump should be positioned fi rmly and horizontally (on a
brick).
- You can adjust the pump's fl ow rate (+/-) by turning the control knob (9)!
