Maintenance

5.1 Safety Information

The safety information given in the following applies to all maintenance work.

Notice safety information 0.1 to 0.3.

Disconnect the electrical power before disassembling the pump. Make
absolutely sure that the pump cannot be accidentally started (logout/
tagout).

If the pump has been pumping harmful substances, determine the nature
of hazard and introduce suitable safety measures. Observe all safety regu-
lations !

When shipping contaminated pumps which require approval by the author-
ities, you must observe the applicable packaging and shipping regulations.

All maintenance and cleaning work described in this section must be car-
ried out only by suitably trained personnel.

Improper maintenance or repairs may affect the service life and perfor-
mance of the pump, and cause problems when filing warranty claims.

Advanced repair work not described here should be left to the Oerlikon
Leybold Vacuum service.

We would like to point out that Oerlikon Leybold Vacuum offers training
courses on the maintenance, repair, and troubleshooting of RUVAC pumps.
Further details are available on request.
