4.4.2 Exhaust connection (OUT)
WARNING
Risk of bursting due to excess pressure in the ex-
haust line.
Unacceptably high pressure in the exhaust line may cause
the vacuum pump to burst or damage seals.
Ø
The exhaust line (outlet, gas outlet) must always be open
and free of pressure.
Ø
Always lay the exhaust hose so that it is descending, or
take measures to prevent condensate return flow into
the vacuum pump.
Ø
Observe the maximum allowable pressures and pressure
differentials.
