5.1 Safety Information
The safety information given in the following applies to all maintenance work.
Notice safety information 0.1 to 0.4.
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.
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 Leybold
service.
We would like to point out that Leybold offers training courses on the mainte-
nance, repair, and troubleshooting of RUVAC pumps. Further details are
available on request.
5.2 Exchanging the Lubricant
Notice safety information 0.3 to 0.5.
The oil-fill ports must be sealed air-tight. In the presence of a vacuum, the
entry of air may cause oil-containing gas to enter the pumping chamber via
the impeller seals.
When using PFPE as intended, PFPE is not subject to ageing. It must only be
changed if it is contaminated by the process gas. It can only be determined
for each individual case when the PFPE is so contaminated that it must be
changed.
In case the pump suffers a severe mechanical failure, the possibility of
hazardous substances being released owing to their thermal decompositi-
on cannot be excluded. When opening the pump wear suitable personal
protection equipment.
For recycling contaminated PFPE we ask you to consult us. As PFPE we
recommend our LVO 400 or LVO 410.
Change the synthetic oil more frequently when pumping corrosive vapors or
large amounts of dust or when cycling frequently from atmospheric to wor-
king pressure.
