2.3 Thermal Hazards
CAUTION:
The surface of the pump may attain temperatures over 80 °C. There is the risk of burn
injury.
1.
Before servicing and maintenance work, always leave the pump to cool down.
2.4 Hazards Caused by Materials and Substances
DANGER:
Before commissioning the pump, make sure that the media which are to be pumped
are compatible with each other so as to avoid hazardous situations. Observe the
instructions for proper and improper use of the pump in Conforming Use.
2.5 Noise Hazard
CAUTION:
The noise level of the pump during ultimate pressure operation corresponds to the
values stated in the technical data. In other operating modes and depending on the
connected vacuum system, higher values can be expected. Make sure that suitable
protection measures are taken to protect your hearing.
2.6 Risk of Damaging the Pump
1.
Before starting up for the first time, the motor circuit must be equipped with a
suitable protective motor switch. Please take note of the information in these
Operating Instructions and on the electric motor (wiring diagram).
2.
Do not allow the ingestion of objects (screws, nuts, washers, pieces of wire, etc.)
through the inlet port. If required, use an inlet filter.
3.
Do not use the pump for applications that produce abrasive or adhesive powders or
condensible vapors that can leave adhesive or high viscosity deposits. When
planning to pump vapors other than water vapor please contact our sales or service
department for advice.
4.
This pump is suited for pumping water vapor within the specified water vapor
tolerance limits.
5.
Avoid vapors that can condense into liquids when being compressed inside the
pump, if these substances exceed the vapor tolerance of the pump.
6.
In the case of wet processes we recommend the installation of liquid separators
upstream and downstream of the pump as well as the use of the gas ballast.
7.
The exhaust line should be laid so that it slopes down and away from the pump so
as to prevent condensate from back streaming into the pump.
8.
Avoid the entry of particles and fluids.
9.
The air intakes of the pump and the motor must remain free.
