WARNING
Hazard of the pump head bursting due to excessive
pressure increase

Do not exceed max. permissible operating pres-
sure (see Chapter 4. Technical Data.

Monitor pressure during operation.

If the pressure exceeds the maximum permissi-
ble operating pressure, immediately switch off
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 is not ex-
ceeded.

Ensure that the pump outlet is not closed or con-
stricted.
Excessive pressure (with all of the related hazards) can be pre-
vented by placing a bypass line with a pressure-relief valve be-
tween the pressure and suctions sides of the pump. For further
information, contact our technical adviser (contact data: see
www.knf.com).
With the pump at a standstill, open pressure and suction lines to
normal atmospheric pressure.
WARNING
Automatic starting can cause personal injury and
pump damage
When the operation of the pump is interrupted by the
thermal switch or the trigging device for PTC sen-
sors, the pump will restart automatically after cooling
down.

Take all necessary care to prevent this leading
to a dangerous situation.
7.3. Switching Pump on/off
Switching pump on
The pump may not start up against pressure during switch-on.
This also applies in operating following a brief power failure. If
a pump starts against pressure, it may block. This activates the
overload switch and the pump switches off.

Make sure that normal atmospheric pressure is present in the
lines during switch-on.

Pumpe am Netzschalter einschalten (siehe Fig. 1/ 3 in Kapitel
5).
Depending on the applied electrical voltage, initialization of the
electronics may take up to one second before the pump starts.
