NOTICE
Overvoltage!
An incorrect voltage range setting can damage the motor.
Always check the set voltage range before switching on the pump.
Only change the voltage range when the pump is disconnected from the power
mains.
Three-phase motor The three-phase current motor circuit
The connections U1 - L2, V1 - L1 and W1 - L3 result in a clockwise rotation of the motor
shaft as seen looking towards the motor fan.
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.
Fig. 7: Motor coil and connecting plate of Delta Connection (for low voltage)
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.
Fig. 8: Motor coil and connecting plate of Star Connection (for high voltage)
NOTICE
Do not start with star/delta connection.
Always start motor directly.
Inspection of the direction of rotation
For pumps with three-phase motors, it is necessary to check the direction of rotation!
14
Motor protection
Installation
CAUTION
Operating fluids may leak out!
If the direction of rotation is incorrect, there is a danger that operating fluids may leak at
the vacuum flange.
Always check the direction of rotation before filling in operating fluid.
Remove the locking cap from the exhaust flange (if existing).
Switch the pump on briefly (from 2 to 3 sec.).
– The motor and motor fan must turn in a clockwise direction (see the arrow on the
support stand).
If the direction of rotation is incorrect: Swap two phase contacts at the connecting ca-
ble.
Fill up the operating fluid.
The transmission power of the pump’s magnetic coupling is so great that the coupling is no overload protection for the motor.
With PTC temperature sensors (3PTC)
Pump motors equipped with PTC temperature sensors (3PTC) in the stator windings can
be connected to a PTC resistor tripping device for protection against overload. Other approved motor temperature monitoring can be used also by the operator.
Tripping devices store the shutdown event and need to be manually switched back on
again via the integrated RESET button or via the external RESET S3. Mains-ON is detected as an automatic RESET.
Set up the connections so that the directional rotation indicated on the pump is main-
tained, regardless of the representations in the current flow diagram.

Operation
6Operation
6.1 Before switching on the pump
Check the operating fluid level in the sight glass.
Compare the voltage and frequency information on the rating plate with the mains volt-
age and frequency values.
Check that the exhaust connection allows free flow (max. permissible pressure 1500
hPa absolute).
– Activate the shut-off valves in such a way that they open before or at the same time
as the pump is started.
Protect the pump sufficiently from taking in contaminants by means of suitable precau-
tions (e.g. dust filters); if necessary, check operating fluid regularly or replace at shorter intervals.
6.2 Switching on
The pump can be switched on in any pressure range between atmospheric and
ultimate pressure.
The ideal operating condition of the pump is achieved during continuous operation. Cyclic operation is possible, but 10 cycles per hour should not be exceeded and the operating phase should always be longer than the downtime (non-operation time).
No special precautions are necessary when pumping dry gases. In order to attain the
lowest possible ultimate pressures, the gas ballast valve should be closed.
Hot surface!
Danger of burns if hot parts are touched. Depending on the operating and ambient conditions, the surface temperature of the pump may rise above 70 °C.
In this case, use suitable finger guards.
Switch on pump at main switch 15.
Switch on the pump with the vacuum flange closed and allow to warm up for 30 min-
utes.
Check operating fluid level only when the pump is warm and running; therefore
– close vacuum flange and gas ballast valve,
– correct filling level during operations: within the markings at the sight glass frame,
– check operating fluid daily in non-stop operation, otherwise whenever the pump is
switched on. Refilling is possible when the pump is in final vacuum operation.
6.3 Pumping condensable vapours
Should the process gases contain condensable gases, the rotary vane pump must be
operated with gas ballast (i.e. with an open gas ballast valve).
Bad final vacuum and damage to the pump!
Danger of condensation and corrosion due to exceeding the water vapour compatibility
during operation without gas ballast or in case of insufficient supply of flushing gas.
Only pump vapours when the pump is warm and the gas ballast valve is open.
When the process has been completed, allow the pump to continue running for
about 30 minutes with the vacuum flange closed and the gas ballast open for operating fluid regeneration purposes.

– Closed when fully turned to the right; open when fully turned to the left.
Gas ballast valve with solenoid valve
To control the flow of the flushing gas externally, an electromagnetic valve can also be
used as an alternative to the versions described above. The valve makes it easier to operate the gas ballast and allows clean air or other gas to be let in in a process-controlled
manner.
NOTICE
Flushing gas pressure higher than allowed endangers the operational reliability
of the pump.
The power input of the pump, the temperature and the ejection of operating fluid will increase.
Observe the maximum permissible flushing gas pressure of 1500 hPa (absolute).
Set the amount of flushing gas on site; dosing is not possible when using a solenoid
valve!

Operation
6.5 Switching off the pump
The pump can be switched off in any pressure range.
Rotary vane pumps have an integrated safety valve on the intake side. If the differential
pressure between the exhaust side and the intake side is 250 hPa, then the valve closes automatically and vents the pump when the pump is switched off.
Switch the pump off at the mains switch or disconnect from the mains in a secure man-
ner.
Venting the vacuum
chamber
Danger of backflow of operating fluid into the intake line!
Contamination of the connected vacuum system!
Vent the vacuum chamber within 30 s, regardless of the chamber size.
For a longer venting process, use an additional shut-off valve and shut off the intake
line after switching off the pump.
NOTICE
Maintaining the vacuum in the chamber
NOTICE
Danger of backflow of operating fluid into the intake line!
Contamination of the connected vacuum system!
Because the safety valve of the pump is not suitable for longer-term sealing, install
an additional shut-off valve in the intake line.
Shut off the intake line immediately after switching off the pump.

7.2 Changing the operating fluid
The service life of the operating fluid is dependent on the application area for the pump.
It must be changed if:
● The specified ultimate pressure is no longer reached
● The operating fluid in the sight glass is visibly contaminated, milky, or cloudy
● The operating fluid is thermally aged, identifiable by its color ID value (applies to min-
eral oils only).
Depending on the applications, Pfeiffer Vacuum recommends determining the exact service life of the operating fluid during the first year of operation.
The replacement interval may vary from the guide value specified by Pfeiffer Vacuum
depending on the thermal and chemical loads, and the accumulation of suspended particles and condensation in the operating fluid.
Hot operating fluid!
Danger of burns when draining due to contact with skin.
Wear suitable protective clothing.
Use a suitable collecting vessel.

Allow pump to run for a maximum of 5 seconds with the vacuum flange open.
Drain off remaining operating fluid.
– In case of serious contamination, the operating fluid will have to be changed sev-
eral times (flushing):
Fill up with operating fluid and check the filling level (see p. 17, chap. 5.5).
The level of deterioration of operating fluid P3 can be determined for clean processes
with the colour scale (in accordance with DIN 51578); supplementary sheet PK 0219
BN on request or at www.pfeiffer-vacuum.com.
Suck off operating fluid from the pump through the operating fluid filler opening.
Fill the specimen in a test tube or some similar vessel and test by holding against the
light.
Where discolouration is red brown (equivalent to 5 on the scale) change operating flu-
id at the latest.
If the interior of the pump is heavily contaminated with process residues, we recommend
performing several changes of operating fluid to flush away the contamination:
Operate the pump with the gas ballast open until the pump has warmed up.
Drain the operating fluid again and check for contamination, flush again if necessary.
Take off the cap and clean the sight glass and pump system externally (without clean-
ing agent).
Replace the filter elements in the accessories.
Screw the operating fluid drain screw back in.
Fill up with operating fluid and check the filling level (see p. 17, chap. 5.5).
Screw in operating fluid filler screw 304.

7.3 Changing the kind of operating fluid
When filling up, topping up or changing the operating fluid, always use the type of operating fluid indicated on the pump type plate. If, for example, amended process conditions
require the use of a different operating fluid, the fluid can be changed as follows:
Changing the type of operating fluid.
A change of operating fluid type can be only be made between mineral (P3) and synthetic operating fluid (D1). It is not possible to change from these two types to F4/F5 or
the other way round!
For the two flushing processes and final fill, the pump needs to be filled up three times
with fresh operating fluid, and this is the amount of operating fluid required.
Perform two flushing processes with the new operating fluid.
Clean any accessories present such as the ONF/OME or ORF/ODK and replace their
filter elements; pay attention to whether more operating fluid is required.
Fill the pump for the final time with the third filling.
Note down the current type of operating fluid in an appropriate place on the pump
(preferably on the type plate).
