3
Contaminated parts can be detrimental to health and environment.
Before beginning with any work, first find out whether any parts are
contaminated. Adhere to the relevant regulations and take the neces-
sary precautions when handling contaminated parts.
4
The user has to ensure that all appropriate safety codes and all safety
procedures are applied in case of pumping toxic, chemically reactive,
corrosive gases and/or pyrophoric substances. Before using the
RUVAC pumps with toxic and/or aggressive gases, it is imperative that
you consult your local Leybold office.
5
Leybold is not in a position to perform servicing (repairs) and waste
disposal of radioactively contaminated pumps. Both needs to be
ensured from the side of the user.
6
When pumping hazardous gases you must assume the presence of
corresponding residues in the pump.
7
After having operated the pump, the cooling water lines may suffer
from microbiological contamination. Introduce corresponding safety
precautions.
8
The intake and the discharge lines should be checked regularly for
leaks. There exists the danger of escaping gas.
9
The cooling water used must not attack stainless steel (note the cool-
ing water quality).
10
When changing the oil, remove any escaped oil as otherwise there
exists the risk of slipping.
11
After having completed the installation work we recommend running of
a leak test on the complete installation at an absolute pressure of 1100
mbar. Otherwise the possibility of escaping of process gases cannot
be completely ruled out.
12
Some Roots pumps use perfluoropolyether (PFPE) as lubricant.
When handling PFPE you should observe the following:
During thermal decomposition at temperatures over 290 °C toxic and
corrosive gases are released. When handling PFPE keep it way from
open fires. Do not smoke in the work area.
Touch the inner sections of the pumps only while wearing clean gloves,
and use clean tools;
do the necessary work in clean and dry rooms;
after having removed the pump from its packaging, start it up as
quickly as possible;
as cleaning agents solvents based on hydrofluorether compounds may
be used.
