Commissioning for operation with liquid
concentrate
Commissioning must be done by certified
service persons.
Wear personal protective equipment.
Observe the chemical manufacturer's safe-
ty data sheets (SDS) and safety instruc-
tions of the used chemicals.
Make sure that all electrical, hydraulic and
mechanical installation is done correctly
and all system components are ready for
operation. The system must be stopped
and control mode must be "Local".
Some pre-assembled mechanical and hy-
draulic connections in the system are loos-
ened for transport. Make sure all connec-
tions are tightened before commissioning.

not designed to carry the weight of a per-
son.
Make sure that the liquid-concentrate line
is connected with a foot valve and installed
with flooded suction to avoid dry-running of
the pump.
