Vacuum
WARNING
►
Hazard due to sudden ventilation of the vacuum apparatus.
►
Due to sudden ventilation, the vacuum apparatus can explode.
►
Prevent sudden ventilation. Check the pressure in the vacuum appa-
ratus before you disconnect the pneumatic connections.
A vacuum can also exist in the vacuum apparatus when the device is
switched off.
GLASS APPARATUS
►
Glass apparatus is especially endangered.
Make sure that the glass apparatus is vacuum-proof and non-breaka-
ble.
2.5 Device-specific hazards
2.5.1
Reliable operation
CONVEYING VAPORS
►
When conveying vapors, condensation may form inside the vacuum
pump. This can (greatly) reduce the service life of the components.
►
The device must be at operating temperature before applications are
started. This will reduce condensation formation in the vacuum pump.
Do not operate the device without a separator or emission condenser. The separator can
only be emptied after the vacuum system has been ventilated. The condensate must then be
disposed of in accordance with legal requirements.
Note possible hazards caused by the required substances (see section
In addition, note the following:
It is not permissible to use the device to convey liquid materials.
The exhaust line must be freely and sufficiently sized.
The exhaust line must be routed in such a way that the condensate can drain.
Check the glass apparatuses for damage before use.
2.5.2
Temperatures
MEDIA/OPERATING TEMPERATURE
►
The permissible media temperature must not be exceeded.
►
Ensure that the maximum ambient temperature is not exceeded. Suffi-
cient ventilation around the device must be ensured.
►
Values for permissible operation: see section 3.2 Characteristic values.
