Safety information
Risk of burns due to hot surfaces or overheating
The surface of the vacuum pump can reach operating tempera

, in particular when pumping heated media. The sur
‑
face temperature of the silencer in particular might be elevated in
case of high gas flow.
>
Avoid direct contact with the surface.
>
Use protection against accidental contact if the surface tem
‑
perature is regularly elevated.
>
Allow the vacuum pump to cool down before performing main
‑
tenance work.
The vacuum pump can be damaged due to overheating. Possi
‑
ble causes include insufficient air supply to the fan and failure to
maintain minimum distances.
>
When installing the device, ensure that there is a minimum
distance of 5 cm between the fan and adjacent parts (such as
the housing, walls, etc.).
>
Always ensure a sufficient air supply; if applicable, provide
external forced ventilation.
>
Place the device on a stable surface; a soft surface such as
foam rubber as a sound absorber can impair and block the air
supply.
>
Clean polluted ventilation slots.
>
Remove covers from the device before operating it.
>
Avoid excessive heat input due to hot process gases.
>
Observe the maximum admissible media temperature
