Static Electricity
The pump needs to be sufficiently grounded so as to avoid any electrostatic
charging. This is attained when properly connecting the electric ground conductor
to the motor. During normal operation no hazardous generation of
charges will occur on the plastic coupling or the fan (for further information
relating to the hazards caused by static electricity, see CENELEC report
CLC/TR 50404: 2003 Electrostatics - Code of practice for the avoidance of
hazards due to static electricity).
Only original Leybold oil filters and gas inlet filters must be used since these
have been designed such that proper connection to ground is ensured. Dust
on the surfaces must only be removed using a moist piece of cloth so as to
exclude the possibility of generating sparks.
Chemical Reactions
The pump must not be used in connection with reactive or corrosive gases,
which might result in an exothermal chemical reaction.
Additional Safety Measures
Overheating the pump can give rise to temperatures which exceed the maximum
permitted surface temperature.
In order to prevent overheating, installation and maintenance need to be
done in accordance with the information provided in these Operating
Instructions. Especially the correct oil level needs to be maintained.
The oil must be exchanged within the recommended interval or earlier if contaminated
by the process gas.
Additional Maintenance Requirements
In those cases where dust can deposit itself on the pump or the motor surfaces,
measures must be introduced which ensure that such deposits are
removed on a regular basis.
In order to ensure that the defined safety level is complied with, use only original
Leybold spare parts.
In addition to the maintenance work described in the Operating Instructions
every 15.000 operating hours or every three years a complete refurbishment
of the pump including a replacement of the bearings and the couplings
should be scheduled.
