4.1. Filling Up And Checking The Operating
Fluid
Standard version pumps are tested with opera-
ting fluid P3. Guarantees relating to attainment
of final pressures and trouble free functioning
apply only providing this operating fluid is used.
The delivery consignment contains sufficient operating fluid
for one filling (valid only for P3).
Pumps for special applications (e.g. for pumping corrosive
gases) can be operated with special operating fluids such as
F5 and other Pfeiffer Vacuum operating fluids. The use of
such operating fluids requires prior authorisation from the
manufacturer.
P3 must be disposed of in accordance with local waste dispo-
sal regulations.
➡
Remove operating fluid filler screw 42.
➡
Fill up with operating fluid included in the consignment
(only for P3); refer to rating plate for correct quantity.
➡
Replace operating fluid filler screw 42; be careful with the
O-ring.
CAUTION
➡
Check operating fluid level only when the pump is warm
and running and vacuum connection 1 and gas ballast
valve are
closed.
➡
The level of operating fluid must always be between the
top and the middle of the sight glass 44.
➡
Topping up operating fluid is possible when the pump is
running and in final vacuum operations.
➡
In non-stop operations check operating fluid daily,
otherwise whenever the pump is switched on.

4.1.2. Operating Fluid F5
Only the synthetic operating fluid F5 may be used for corrosi-
ve gas model pumps. The use of other operating fluid must be
cleared by the manufacturer.
When working with synthetic operating media,
the manufacturer’s directions must be
observed.
If ‘’F5’’ is heated above 250°C, toxis vapours
which can harm the airways are given off.
Do not allow ‘’F5’’ to come into contact with tobacco products
(danger of poisoning when ignited). The precautions
necessary in the handling of chemicals must be observed.
Operating fluids containing toxic or aggressive
substances require special treatment. The
instructions for handling such media must be
observed.
Never fill into pumps which contain mineral oil
residues.
If there is a noticeable loss of operating fluid,
the radial shaft seals should be checked.
If operating fluid is leaking out underneath the
casing 15 from the opening between the
support stand 28 and motor 3, the radial shaft
seal must be replaced. Please contact your local Pfeiffer-
Service (see Section 7.).
