Trough in the pipe
Dimension the pipeline connections based on
pressure, temperature and medium properties.
Connect the pipes to the pump so that they are free of ten-
sion and compression to ensure that no stresses are applied
to the pump.
Secure pipes to ceilings, walls, or floor using pipe clamps.
Align pipes flush with pump connections using a bracket.
6.5
Electrical connection
Electrical connection may only be performed by a qualified elec-
trician.
1. Heed the connection values on the motor's rating plate. The
specified voltage must not be exceeded.
2. Only connect the motor to fuse-protected circuits to prevent
excessive current consumption.
3. Connect the motor according to the circuit diagram in the
terminal box of the motor.
4. Protect cable feedthroughs against penetration by moisture.
5. Turn on the motor for 2 to 3 seconds and low speed. Com-
pare the actual direction of rotation of the motor fan impel-
ler with the arrow on the pump head.
6. Reverse the polarity if the pumping direction is incorrect.
6.6
Cleaning
Only use cleaning agents that comply with the hygiene guide-
lines for the respective pumping medium.
1. Before sealing the pump ensure that there are no foreign
objects inside the pump or pipes.
2. Seal the pump.
3. Connect the pipes.
4. Thoroughly clean the pump and the pipe system before ini-
tial use.

Operation
7.1
Safety instructions
– Danger of bursting: If the allowable pressure or temperature
range is exceeded, the pump may burst or become leaky.
Maintain the pump pressure and temperature within the
specified ranges. See
"Order-Related Documents"
in the
attached documents.
– Danger of bursting: Cold extinguishing agents used to extin-
guish a pump fire can cause the hot pump to burst.
Do not cool the pump down excessively when extin-
guishing the fire.
– Danger of burning: Pumping of hot media can cause the
pump to become very hot.
Check the temperature before touching the pump.
Only touch the pump if you are wearing suitable gloves.
– Noise emissions: The A-weighted sound pressure level of the
pumps can be greater than 80 dBA.
Always wear ear protectors in the vicinity of the running
pump.
The local noise exposure regulations must be complied
with.
See noise emission values for the pumps:
.
– Pump running in reverse direction despite emergency shut-
off: If the pump is shut off using the emergency shut-off
function, the pumping medium in the discharge line will
flow in reverse direction through the pump.
Install a check valve.
7.2
Commencement of Operation
NOTE
Pump runs dry
Running the pump without medium results in damage to the
magnetic coupling.
Ensure that the pumping medium always reaches the upper
edge of the outlet side in the pump before and during oper-
ation.
The pump must be vented.
