fl ow is
lower than 14 slm,
a hazard stops the
pump after 80 s
When the pressure
reaches 2000 hPa,
a hazard stops the
pump immediately
When the motor tem-
perature reaches
150 °C, a hazard
stops the pump imme-
diately
When the differen-
tial pressure in the
exhaust box reaches
1.6 hPa, a hazard
stops the pump after
80s
When the electrical
ground leak is lower
than 30 mA, the main
breaker is activated
and the pump stops
