Please read these instructions thoroughly before using the pump!
Use: Centrifugal pump for submersible usage with resin encapsulated
motor.
The pump is suitable for use in water, e.g. for garden ponds, fountains,
terraced fountains, indoor fountains, in fi shponds, for the operation of
fi lter systems, fl owing brooks etc. as well as for circulating and oxygena-
ting water.
The pump may not be used in or on the side of swimming pools!
For all technical data please refer to the type plate.
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)
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 water level of approx. 12 cm is required for submersible use in order to
prevent the pump from taking-in air.
- 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)!
