Filling the pump and the suction line
When the pump is put into operation for the first time, the pump housing must be completely bled.
To do this, the pump housing must be completely filled with water via the filling/bleed screw as shown in the
instructions below.
1. It is essential to use a suction line that includes a non-return valve and to bleed it - i.e. to fill it with water.
After this procedure, connect the suction line to the suction connection of the pump.
2. Open the filling/bleed screw by turning it anti-clockwise.
Now fill the pump, mounted on the carrier provided, with water until it is completely full.
3. Close the filling/bleed screw by turning it clockwise.
4. It may be necessary to carry out this procedure (filling the pump housing) several times. Check that there is
no leakage.
6. Electrical connection
The unit is equipped with a mains connection cable and a mains plug. It must only be replaced by qualified staff to
avoid any danger. Please do not use the mains connection cable to carry the pump, and do not use this cable to
pull off the plug from the socket, either. Protect the mains connection cable and mains plug from heat, oil or sharp
edges.
The values stated in the technical details have to correspond to the mains voltage. The person
responsible for the installation has to make sure that the electrical connection is earthed in
compliance with the applicable standards.
The electrical connection has to be equipped with a highly sensitive residual current circuit-
breaker (FI
switch): ∆ = 30 mA (DIN VDE 0100-739).
If extension cables are used, their cross-section must not be smaller than that of rubber-
sheathed cables of the H07RN-F (3 x 1,0 mm²) short code. The mains socket and the plug-
and-socket elements have to be in splash water-proof design.
7. Putting into operation
Nobody must be in the water while the pump is running.
The pump must only be operated in the performance range indicated on the type plate.
Dry-running - i.e. operating the pump without discharging water - is to be avoided since the
absence of water may cause the pump to run hot. This may cause considerable damage on
the device. In addition, there is very hot water in the system, so there is a
risk of scalding. If the pump is running hot, unplug it from the mains and let the system cool
down.
Please make sure that the electrical plug connections are in the flood-proof area.
As long as the device is connected to the electrical mains, one must never reach with
one’s
hands into the opening of the pump.
The pump must not run while the pressure port or the pressure line are closed.
Please inspect the pump visually prior to each use. This applies in particular to the mains connection line and the
mains plug. Make sure that all screws are firmly tightened, and verify the perfect condition of all connections. A
