Use
The skimmer 250 removes coarse soiling from the pond surface. The integrated pump takes the pond water in via the skimmer flap and conveys the cleaned water back into the pond through the pump outlet. The surface soiling is retained by the basket. The Skimmer 250 is recommended for a maximum water surface area of 250 m².
Intended use
The Skimmer 250, in the following text termed unit, may only be used to clean normal pond water at a water temperature of +4°C to + 35°C. Do not use the unit in swimming ponds.
The unit floats on the water. To keep it in position, the enclosed wire cables
are fastened to the unit and either to the bank or to the pond bottom.
Anchoring the unit at the bank (A): Shorten the two wire cables to the desired
length. Form loops at the cable ends and fasten with the cable clamps (3).
Hook the cables into the eyebolts (4) at the skimmer housing by means of
bayonet hooks (1). Knock the two tent pegs (2) into the bank ground.
Important: Adhere to the specified bracing angles (6) to prevent the unit from
moving. Set the unit in the water and hook the cables to the tent pegs (2)
using the bayonet hooks (1). Attention: Pull relieve the connection cable (8)
and protect the power plug from moisture!
Anchoring the unit to the pond bottom (B): Shorten the two wire cables to the
desired length (minimum 5 m). Form loops at the cable ends and fasten with the
cable clamps (3). Hook the cables into the eyebolts (4) at the skimmer housing
by means of bayonet hooks (1). For anchoring to the pond bottom, screw the
enclosed threaded hooks (9) including the dowel, for instance, into two
sufficiently heavy stones. Hook both cables with bayonet hooks (1) in the
threaded hook (9), lower the stones to the bottom of the pond and set the unit
on the water. Attention: Pull relieve the connection cable (8) and protect the
power plug from moisture!
