7.2. Starting
 Only operate the pump under the operating parameters and
conditions described in chapter 4, Technical data.
 Make sure the pump is used properly (see chapter 2.1).
 Make sure the pump is not used improperly (see chapter 2.2).
 Observe the safety precautions (see chapter 3).
Hazard of the pump head bursting due to excessive
pressure increase
 Do not exceed max. permissible operating
pressure (see chapter 4).
WARNING
 Monitor pressure during operation.
 If the pressure exceeds the maximum permissi-
ble operating pressure, immediately shut down
pump and eliminate fault (see chapter 9. Trou-
bleshooting).
 Only throttle or regulate the air or gas quantity in
the suction line to prevent the maximum permis-
sible operating pressure from being exceeded.
 If the air or gas quantity in the pressure line is
throttled or regulated, make sure that the maxi-
mum permissible operating pressure of the
pump is not exceeded.
Excessive pressure (with all of the related hazards) can be
prevented by placing a bypass line with a pressure-relief valve
between the pressure and suction side of the pump. For further
information, contact your KNF technical adviser.
 With the pump at a standstill, open pressure and suction lines
to normal atmospheric pressure.
