WARNING!
ATEX pumps in areas at risk from explosion
– Make sure that a suitably competent person checks
whether the appropriate installation information from
the "Installation" chapter has been implemented cor‐
rectly.
– Make sure that a "recognised competent person"
checks the electrical installation and in particular the
intrinsically safe power circuits.
– Set the opening pressure of the relief valve to a
maximum of no more than 1.5 times the nominal
pressure of the pump.
WARNING!
Only motors with a frequency converter: Danger of elec‐
tric shocks
– The danger of an electric shock remains for 3
minutes after the mains voltage has been switched
off on conducting parts of the motor with integrated
frequency converter (FC) and on the lines them‐
selves.
– After switching off, allow the unit to stand for 3
minutes before opening the terminal box.
Only motors with a frequency converter: The motor can be damaged
The input current limiter could be damaged if a motor with integrated
n
frequency converter is restarted within 3 minutes of the mains voltage
being switched off.
After switching off, allow the unit to stand for at least 3 minutes before
n
restarting.
The metering pump may only be operated by trained personnel. The oper‐
ator is responsible for ensuring that under the given operating conditions
(pressure, temperature, corrosiveness, etc.) danger to the operating per‐
sonnel is avoided by use of appropriate accident prevention measures.
Feed chemical could escape
Check suction and pressure lines, and liquid end with valves, for leak-
n
tightness and tighten if necessary.
Check whether the necessary flushing pipes or bleed lines have been
n
connected.
Liquid end may be damaged
Always fit a filter in the suction line with feed chemicals with a particle
n
size greater than 0.3 mm
Prior to commissioning, check that the power end motor or pump and cor‐
responding ancillary equipment is connected in compliance with the regu‐
lations.
When using pumps with speed control, observe the instructions in the fre‐
quency converter operating instructions.
Observe the details in the Chapter "Technical data", such as pressure, vis‐
cosity, resistance, etc.
