Mains connection
The pump is electrically connected to a properly installed protective contact socket with a mains
voltage of 230 V / 50 Hz.
Assembly
To avoid long suction lines and the resulting loss of performance, the pumps should be installed at or
below the water level if possible.
In the case of fixed pumping systems, the electric pump can be anchored on the ground. Use the
holes provided in the base plate for this.
The pumps must be installed in a well-ventilated, dry and flood-proof location.
Cable installation
The suction line must be protected against negative pressure and be installed approx. 30 cm
below the water level. This avoids the formation of whirls and the inevitably associated air
entry.
The line connections must be completely airtight. Bends and waves formed by the lines should
be avoided as far as possible.
The suction line should have a minimum gradient of 2% over its entire length so that no air
can remain inside the system.
The pressure line must have a diameter that is either equal to or larger than that of the pump
pressure connection.
The suction and pressure lines must never rest on the pump.
Make sure that all connections are tight so that the pump does not come into contact with
moisture and possibly be damaged.
We recommend the installation of a foot valve. When setting up, make sure that the pump is
not self-priming.
Operation
1.
Fill the system with water to find and repair any leaks.
2.
Open any slide valves in the pressure and suction lines and check whether all lines are
connected.
3.
Let water run into the pump via the pool overflow / suction or fill the suction line and the pump
body completely with water. Not being self-priming, the pump must be completely filled before
operation to prevent it from running dry.
4.
Plug in the pump and check that the pump is circulating the water.
5.
If the pump is used above the pool water level, a foot valve must always be installed at the
beginning of the suction line so that the water does not run back from the suction into the pool
after the pump is switched off.
6.
If the motor does not start or if no water is transportend, please switch off the pump and check
whether there is any blockage inside the line system or inside the pump.
