Observe the technical data
Test the diaphragm rupture sensor
WARNING!
Only motors with a frequency converter: Danger of electric
shock
On conducting parts of the motor with an integrated fre‐
quency converter and on the lines themselves, there remains
a risk of an electric shock for 3 minutes after switching off the
mains voltage.
–
After switching off allow the device to stand for 3 minutes
before opening the terminal box.
CAUTION!
Only motors with a frequency converter: The motor may be
damaged
If a motor with an integrated frequency converter is restarted
within 3 minutes of switching off of the mains voltage, the
input current limiter could be damaged.
–
After switching off, allow the device to stand for at least 3
minutes before restarting.
CAUTION!
Feed chemical could escape
–
Check suction and discharge lines and liquid end with
valves for leak-tightness and tighten if necessary.
–
Check whether the necessary flushing pipes or bleed
lines are connected.
CAUTION!
Prior to commissioning, check that the power end motor and
corresponding ancillary equipment is connected in compli‐
ance with the regulations.
CAUTION!
When using pumps with speed control, observe the instruc‐
tions in the frequency converter operating instructions.
CAUTION!
Danger of material damage
Observe the details in the chapter "Technical Data" (pres‐
sure, viscosity, resistance, ...).
CAUTION!
Feed chemical can escape unnoticed
If the diaphragm rupture sensor does not stop the pump or
no alarm is triggered, feed chemical can escape unnoticed.
–
Trigger the diaphragm rupture indicator - see chapter
"Repairs" and in so doing check the reaction of the anal‐
ysis unit.
