⇒ If the operating fluid is contaminated (black), fill
with new operating fluid. Dispose of operating
fluid in accordance with the local regulations!
⇒ Notify customer service if an operating fluid con-
tains metal chips!
6. Pour in operating fluid: Rotate the pump until the
opening points upwards. Fill-in the operating fluid into
the opening.
⇒ Comply with the specifications for operating fluid
locations and quantity! When recycling the operat-
ing fluid, check the quantity and if required adjust
it!
7. Clean the screw plug, replace the seal ring and screw it
back in. Max. tightening torque: 8 Nm!

Stationary wet well installation
NOTICE
Delivery problems due to water level being
too low
The hydraulics are self-venting. As a result, smaller
air cushions are dissolved during the pumping pro-
cess. If the level of the fluid is lowered too much, the
volume flow can be interrupted. The minimum per-
missible water level must reach the upper edge of
the hydraulics housing!
The pump is installed in the fluid for the wet well in-
stallation. For this, a suspension unit must be installed
in the chamber. On the pressure side, the on-site pipe
system is connected to the suspension unit and on the
suction side to the pump. The connected pipe system
must be self-supporting. The suspension unit must not
support the pipe system!
CAUTION! If the motor emerges during operation,
observe the operating mode for non-immersed oper-
ation (S2-15, S3 10 %*)!
* Operating mode S3 25 % is permitted if the necessary
motor cooling is guaranteed before the motor is
switched on again! To ensure the required cooling, the
motor must be completely immersed for at least 1 min.!

CAUTION
Damage to the pump due to incorrect install-
ation
Observe the following points during the installation
of the pump:
• Observe the max. permissible tightening torque:
15 Nm (V05) or 25 Nm (V06)
• Do not insert an additional gasket between the
flange and the accessories! A gasket is mounted
on the pump flange!
• Only use accessories with a flange shape in ac-
cordance with EN 1092-2, type A. The use of
other flange shapes is not permitted!
‡ Operating space/installation location is prepared for the
installation.
‡ Suspension unit and pipe system were installed.
‡ Pump is prepared for operation on the suspension unit.
1. Use a shackle to attach the lifting equipment to the at-
tachment point of the pump.
2. Lift the pump, swivel it above the chamber opening and
slowly lower the guide claw onto the guide pipe.
3. Lower the pump until it sets on the suspension unit and
is connected automatically. CAUTION! Hold the power
supply cables slightly taut when lowering the pump!
