3.4. Connecting The Exhaust Side
Pressure can rise to dangerous levels in
exhaust lines.
Lay exhaust lines without built-in shutoff
devices. If a shut-off device is installed for
internal operating reasons or if there is a risk of
excess pressure developing in the lines, official accident prevention regulations must be complied with.
The exhaust line diameter should not be less than 63 DN.
The line from the pump must be laid with a downward
gradient so that condensate is prevented from flowing back
into the pump. Otherwise a trap must be installed.
Expelled gases and vapours can represent a
hazard to health and/or the environment.
For this reason the relevant regulations must
always be complied with when working with
toxic substances. Only officially approved filters
may be used for the separation of such substances. This also
applies when handling toxic or chemically unstable gases
and to gases susceptible to polymerisation or to the formation
of peroxide (see 9. Accessories).
3. Installation
3.1. Preparations For Installation
Do not carry out any unauthorised conversions
or modifications on the pump.
Fill up with operating fluid before operating the
first time (included in a separate pack in the
delivery consignment). When transporting use
only the eyebolts provided for the purpose.
When filled with operating fluid, do not tilt the
pump otherwise operating fluid could escape
via the exhaust opening.
3.2. Pump Assembly And Location
➡ Where stationary installation is involved, anchor the pump
on site.
➡ Sight glass 1 on the front side must be visible and gas bal-
last valve readily accessible.
➡ When installing the pump in a closed housing, ensure the-
re is sufficient air circulation.
3.3. Connecting The Vacuum Side
➡ Keep the connection between the vacuum chamber and
pump as short as possible.
➡ Remove all scaling and loose particles from welded lines
prior to assembly.
– To protect the pump, separators, filters and cooling traps
etc.(see Section 9. Accessories) can be fitted upstream of
the pump. However, the conductance value of the
accessory causes a reduction in volume flow rate.
Where rotary vane vacuum pumps are
anchored, no forces from the piping system
should be allowed to act on the pump.
Suspend, decouple or support all piping
concerned with the pump.

3.5. Connecting To The Mains Power Supply
Power connections must comply with local
regulations. Voltage and frequency information
given on the rating plate must correspond to
the mains voltage and frequency values.
When the electrical connections have been
completed, carry out the earthed conductor test. The pump
must be disconnected from the power before opening the terminal box.
When switching on for the first time, check the direction of
rotation:
Checking The Direction Of Rotation
Check the direction of rotation of the pump
before filling up with operating medium.
➡ Remove blank flange on the exhaust side.
➡ Switch on pump for a short time (max. 5 seconds).
Motor/motor fan must turn clockwise (see arrow on motor
fan cover).
➡ If direction of rotation is incorrect: Interchange two
phases on the connecting cable.

The Three Phase Current Motor Circuit
The three phase motor winding consists of three identical
coils.
Delta Connection
The three coils are connected in series with the connection
point connected to the mains. The voltage of each coil is the
same as the mains voltage whereas the mains current is the
cube root of the coil current. Delta connections are denoted
by the symbol ∆∆.
The voltage between the mains supply lines is called mains
voltage. The mains current is the current which flows in the
supply lines.
Star Connection
The ends of the three coils are connected at the star center.
The terminal voltage is the cube root of the coil voltage; the
mains and the coil current are the same. Star connections are
denoted by the symbol Y.
A star connection three phase motor for 400 V mains voltage
has a coil voltage of 230 V.

Rotation Speed and Operating Hours Monitor RCI 002
3.6. Monitoring Connection
The Rotary Vane Pumps UNO/ DUO 120 A have been designed
so that they can be connected to a Rotation Speed and
Operating Hours Monitor RCI 002, which is connected at
connecting socket 45. For the operation and application of
this device please refer to the relevant operations
instructions.
Important: The instructions in 4.1.2 must be
observed when working with synthetic
operating medium F5.
3.7. Special Models
Helium Tight and Corrosive Gas Models
Helium tight and corrosive gas models are becoming
increasingly important.
– Helium tight models are distinguished by their high level
tightness to the atmosphere. Corrosive gas models are
manufactured with special materials.
– There is a different high vacuum safety valve control.
– The rotor shaft of both versions is sealed with an
additional radial shaft seal. The cavity between the radial
shaft seals 118 and 133 is filled with operating medium and
is supplied by the oiler 136.
– If the gas ballast valve 2 is not available, the opening
should be closed with the locking screw 169 or a special
gas ballast valve with dosing device and hose connection
for flushing gas is available (on request).
– Helium tight models are operated, as standard, with opera-
ting medium P3 and the corrosive gas version with synthe-
tic operating medium F5, also as standard.

4.1. Filling Up And Checking The Operating
Fluid
Standard version pumps are tested with operating 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.
Pumps for special applications (e.g. for pumping corrosive
gases) can be operated with special operating fluids such as
F5 and other PFEIFFER operating fluids. The use of such
operating fluids requires prior authorisation from the
manufacturer.
P3 must be disposed of in accordance with local waste disposal 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.
➡ Check operating fluid level only when the pump is warm
and running and vacuum connection 5 and gas ballast valve are closed.
➡ The level of operating fluid must always be between the
top and the middle of the sight glass 1.
➡ 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 corrosive 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 300°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.
Please note:
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 loca
Pfeiffer-Service (see Section 7.).
4.2. Switching The Pump ON And OFF
When operating the pump gets hot.
The pump can be switched ON and OFF in any pressure
range. On switching off, the built-in high vacuum safety valve
6 to the vacuum plant closes automatically and vents the
pump.
Minimum start-up temperature, in compliance with German
Industrial Standard DIN 28 426: + 12 °C.
On switching OFF (intake pressure < 750 mbar) the built-in
high vacuum safety valve to the vacuum chamber closes
automatically and the pump is vented.

4.3.2 Corrosive Gas Model
Gas ballast valve 2 is fitted with a dosing device and a
flushing gas connection. It has a sliding sleeve which opens
the valve when pushed towards the pump and shuts the valve
when pushed away from the pump (Fig. 8). The dosing device
is closed when the groove in the dosing screw is in the
horizontal position; in the vertical position the dosing device
is fully open. A flow meter enables any intermediate gas volume setting between fully open and fully closed to be made.
Please note:
Flushing gas must be connected when operating corrosive
gas version pumps. The gas ballast valve must be open. Flushing gas pressure may not exceed 1.5 bar. Our specialists
would be pleased to give advice regarding the type and volume of flushing gas required.
11
4.4. Pumping Off Dry Gases
No special measures are necessary. The gas ballast valve
can remain closed.
4.5. Pumping Off Vapours
To prevent their condensation in the pump,
vapours should only be pumped off with the
pump at operating temperature and the gas bal-
last valve 2 open.
Observe pump water vapour tolerance levels
(see Section 8.0 Technical Data). When the process has been
completed, allow the pump to continue running for approx. 30
minutes for operating medium cleaning purposes.

Operating fluid can contain substances from
the medium pumped. Operating fluid must be
disposed of in accordance with the local
respective regulations.
Please request safety instruction data sheets for operating
fluids from PFEIFFER or download from the INTRANET/
INTERNET.
6.2. Re-Setting The Silencer
If the silencer 13 is not functioning, a knocking noise
becomes audible at end vacuum. This does not cause damage to the pump but it may be disturbing in quiet rooms. Setting
can be carried out while the pump is running and the intake
socket and gas ballast valve are closed, using a normal
screwdriver:
➡ The pump must have reached its operating temperature.
➡ Remove locking screw 44 (UNO 120A) or operating medium
filler screw 42 (DUO 120 A).
➡ Using a screwdriver, open the valve spindle 47 approx. 3
turns (flushing) for some seconds and then close it again
completely (clockwise).
➡ Slowly open the valve spindle 47 (1/2 to a complete turn)
until the knocking noise is no longer audible.
➡ Replace locking screw 44 or operating medium filler screw
42 paying attention to the O-ring.
Please note:
Silencer cleaning is described in the service instructions.
When carrying out servicing work, take the following
precautions:
Always ensure the pump cannot be switched
on when carrying out any work on the pump. If
necessary, remove the pump from the system
to carry out inspection work.
➡ Only dismantle the pump as far as is necessary in order to
repair defects.
➡ Dispose of used operating fluid in compliance with local
regulations.
➡ When working with synthetic operating media, toxic
substances and substances contaminated with corrosive
gases, the relevant instructions governing their use must
be observed.
➡ Only use benzine or similar agents for cleaning pump
parts. Do not use soluble cleaning agents.
6.1. Changing The Operating Fluid
The rate of deterioration of the operating fluid depends on the
pump applications.
➡ The level of deterioration of organic operating fluids (for
example P3) can be read off from the colour scale in
accordance with DIN 51578 on the supplementary sheet
PK 800 219 BN/B, on request.
– The colour scale enables precise colour determination.
➡ Fill a specimen in a test tube or some similar vessel and
test by holding against the light.
➡ Where the discolouration is dark yellow to red brown
(equivalent to 4 ... 5 on the scale) change operating fluid.
Where organic operating fluids, for example P3,
are involved, the operating fluid should be
changed at least once a year!
Replacing The Operating Fluid
➡ Switch off the pump.
➡ Unscrew operating fluid drain screw 43 and drain
operating fluid.
The operating fluid temperature can be as high
as 80 °C. During maintenance and repair work,
process related toxic gases and vapours can
escape from the operating fluid which may
become contaminated with harmful substances
(radioactive, chemical etc.).
Disposal of used operating fluid is subject to the relevant
regulations.
