The metering pump can generate a multiple of its rated
pressure. Hydraulic parts can burst if a discharge line is
blocked.
Fit a relief valve in the discharge line.
CAUTION!
Caution: backflow
Metering pumps are not absolutely leak-tight shut-off
devices.
Use a shut-off valve, a solenoid valve or a vacuum
breaker as an absolutely leak-tight shut-off device.
CAUTION!
Personnel injury and material damage / Unit starts
immediately
The pump can start to pump as soon as it is connected
to 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.
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!
Contact with chemicals
De-pressurise, drain and rinse the hydraulic part of the
unit before working on it.

Both flushing connections can always remain closed in
normal mode.
