9.1 Dangers during connection work
The following safety instructions must be observed:
o
Have all work on the pump station and pipe system only carried out by authorized qualified per-
sonnel.
o
Ensure that impurities cannot get into the pump station and pipe system.
o
Ensure that mechanical connections are mounted free of stress.
o
Observe the tightening torques.
o
Have all the work on the electrical equipment only carried out by electricians.
o
Before commissioning ensure correct earthing and equipotential bonding.
o
Before beginning work on the pump station ensure that the electrical power supply is deenergized
and is secured against being switched back on.
o
If the insulation of the electrical cables or wires is damaged, disconnect the power supply immedi-
ately.

ATTENTION
Damage to device through impurity in the pipe system.
► During welding work attach protective covers in front of the connecting flanges.
► Ensure when welding that welding beads and abrasive dust cannot get into the pipe system and
the pump station.
► Ensure that a commissioning filter is installed when the pipe system is flushed and cleaned using
the pump.
ATTENTION

1.
Check whether the reversing valve or the two-way valve moves easily.
If the levers of the valves cannot be turned by hand, remedy the fault before commissioning the
pump station.
2.
Attach protective covers in front of the connecting flanges before welding work.
3.
Place the piping in position and support the weight of the piping. Do not use the pump station as
a support for connected piping.
4.
Install compensating elements if temperature-related material expansion is possible.
