2.2 Safety notes
WARNING!
Danger from hazardous sub‐
stances!
Possible consequence: Fatal or
very serious injuries.
Please ensure when handling
hazardous substances that you
have read the latest safety data
sheets provided by the manufac‐
ture of the hazardous substance.
The actions required are
described in the safety data sheet.
Check the safety data sheet regu‐
larly and replace, if necessary, as
the hazard potential of a sub‐
stance can be re-evaluated at any
time based on new findings.
The system operator is respon‐
sible for ensuring that these safety
data sheets are available and that
they are kept up to date, as well
as for producing an associated
hazard assessment for the work‐
stations affected.

WARNING!
Danger of electric shock
Mains voltage may be present
inside the pump housing.
Immediately disconnect the pump
from the mains power supply if the
pump housing has been dam‐
aged. Only return the pump to
service after an authorised repair.
CAUTION!
Warning of feed chemical
spraying around
The metering pump can generate
a multiple of its rated pressure.
Hydraulic parts may burst if a dis‐
charge line is blocked. -
Correctly install a relief valve in
the discharge line downstream of
the metering pump.
CAUTION!
Warning of backflow
Metering pumps are not abso‐
lutely leak-tight shut-off devices.
Use a shut-off valve, a solenoid
valve or a vacuum breaker for this
purpose.
CAUTION!
Personnel injury and material
damage
The pump can start to pump, as
soon as it is connected to mains
voltage.
Install an emergency cut-off
switch in the pump power supply
line or integrate the pump in the
emergency cut-off management of
the system.
CAUTION!
Device starts immediately
The unit does not have an On/Of
switch and begins to work as soon
as it is connected to the mains
voltage.
Only connect the device to the
mains voltage when all installation
work has been completed and the
pumped chemicals can no longer
escape in an uncontrolled
manner.
CAUTION!
Contact with chemicals
De-pressurise, drain and rinse the
hydraulic part of the unit before
working on it.
Safety and responsibility

Protective equipment
The transparent cover on the
liquid end serves to prevent direct
contact with the rotor and
escaping chemicals in the event
of a ruptured hose.
Information in the event of an emer‐
gency
In the event of an electrical accident,
disconnect the mains cable from the
mains power supply or press the
emergency cut-off switch fitted on the
side of the system. If feed chemical is
escaping, switch off the pump by
pressing [Stop/Start] . If necessary
ensure that the hydraulic system
around the pump is at atmospheric
pressure. Adhere to the safety data
sheet for the feed chemical.
2.3 Intended use

tection (exterior housing, weather‐
proof roof) for external use. The
housing can be affected by direct
sunlight
nOnly allow adequately qualified
and technically expert personnel
to operate the unit
