Hazards encountered by the combination of water and electricity
– The combination of water and electricity can lead to death or severe injury from electrocution, if the unit is incor-
rectly connected or misused.
– Prior to reaching into the water, always disconnect the power supply to all units used in the water.

Correct electrical installation

– Electrical installations at ponds must meet the international and national regulations valid for installers.
– Electrical installations may only be carried out by qualified electricians.
– Only use cables approved for outside use.
– Ensure that the unit is protected by for a rated fault current of max. 30 mA via a fault current protection device.
– Only connect the unit when the electrical data of the power supply is identical to that on the unit type plate.
– Only operate the unit when plugged into a correctly fitted socket. Keep the socket dry.
Safe operation of the unit
– Only operate the unit if no persons are in the water.
– Keep the power plug dry.
– Route the power cable so that damage is excluded.
– Do not carry or pull the unit by the power cable. The power connection cable cannot be replaced.
– Never run the unit without water. The unit would be destroyed.
– Never use the pump for fluids other than water. Other fluids could destroy the unit.
– Never open the unit housing or its attendant components, unless this is explicitly mentioned in the operating in-
structions.
– Never carry out technical modifications to the unit.
– Only use original spare parts and original accessories for the unit.
Assembly and installation (A-D)
Unit assembly (A)
Screw the injector (3) on the pump outlet (4). Push the hose clips (6) over the injector hose (2) and slide the hose ends
on the connection sockets of the injector (3) and on the floating body (1) respectively. Fasten both hose clips (6) at the
hose ends over the connection sockets.
Drum adjustment (B)
Turn out the grip screw (7) to arrest the drum (5). Turn the drum (5) until the injector (3) is in the desired position.
Tighten the grip screw (7).
Adjustment hints (8): Adhere to the specified minimum distances from the bottom of the pond to ensure the proper
function of the injector. When the injector is directed downwards towards to the bottom of the pond, it generates deep
aeration thereby biologically activating the pond sludge. When the injector is directed at a flatter angle, it generates a
stronger water flow.
Unit installation (C,D)
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 ( C ): Shorten the two wire cables to the desired length. Form loops at the cable ends
and fasten with the cable clamps (11). Hook the cables into the eyebolts (12) at the floating body by means of bayonet
hooks (9). Knock the two tent pegs (10) into the bank ground. Important: Adhere to the specified span angles (14) to
prevent the unit from moving. Set the unit in the water and hook the cables to the tent pegs (10) using the bayonet
hooks (9). Attention: Pull relieve the connection cable (13) and protect the power plug from moisture!
Anchoring the unit to the pond bottom (D): Shorten the two wire cables to the desired length (minimum 5 m). Form
loops at the cable ends and fasten with the cable clamps (11). Hook the cables into the eyebolts (12) at the floating
body by means of bayonet hooks (9). For anchoring to the pond bottom, screw the enclosed threaded hooks (15) in-
cluding the dowel, for instance, into two sufficiently heavy stones. Hook both cables with bayonet hooks (9) in the
threaded hook (15), lower the stones to the bottom of the pond and set the unit on the water. Attention: Pull relieve the
connection cable (13) and protect the power plug from moisture!
