Dangers during ventilation
Looking out for dan-
gers during ventila-
tion
Depending on the process, a potentially explosive mixture can form
in installations or other dangerous situations can occur.
Dangers due to residual energy
Possible residual en-
ergies
After the vacuum pump has been switched off and disconnected
from the power network, dangers may still be present due to resid-
ual energies:
n
Thermal energy: Motor waste heat, hot surface, compression
heat.
n
Electrical energy: Installed condensers have a discharge time of
up to 3 minutes.
Please note the following before performing actions:
ð Allow the vacuum pump to cool down.
ð
Wait until the condenser have discharged.
Dangers due to hot surfaces or overheating
Surface tempera-
tures
The surface of vacuum pumps can reach temperatures greater than
70 °C during operation, especially when vacuuming heated media.
ð
Avoid direct contact with the surface or wear heat-resistant
safety gloves if contact cannot be excluded.
ð Provide contact protection if the surface temperature should be
elevated on a regular basis.
ð Allow the vacuum pump to cool down before performing main-
tenance tasks.
Overheating
The vacuum pump can become damaged due to overheating. Po-
tential causes are insufficient air supply to the cooling fan and/or
non-compliance with minimum distances.
ð
When setting up the device, observe a minimum distance of 5
cm between the cooling fan and adjacent parts (e.g. housing,
walls, etc.).
ð
Always ensure that there is sufficient air supply; if necessary,
provide an external forced ventilation system.
ð Place the device on a stable surface. A soft surface, e.g. foam as
sound absorber, can impair and block the supply of air.
ð Clean dirty ventilation slots.
