●Keep the pump away from fixed walls, at a minimum using the value indicated on the diagram be-
low.
5.2 Connecting to the pumping line
The user and/or product integrator is ultimately responsible for the equipment and must apply the spe-
cific safety instructions, in accordance with local regulations.
WARNING
Risk of crushing or cutting in case of contact with moving parts
The pump inlet flange is large enough for body parts (fingers or hands) to the inserted into it, present-
ing a risk of crushing due to contact with moving parts. The inlet and exhaust ports should be sealed
with blanking plates before connection.
►Wait for the pumping line to be connected before removing the blanking plates.
►Wait for the pump to be connected before powering on.
General instructions for installing the pump in the pumping line in accordance with industry
best practices
The inlet and exhaust connections must not put undue strain on the pumping line that could cause leak-
age.
1. Only use accessories on the inlet and exhaust lines with materials and sealing properties that are
compatible with the gases being pumped. Refer to the connection accessories catalog available at
the Pfeiffer-Vacuum website.
2. When assembling the pumping line, include accessories for isolating the pump from the pumping
line and making maintenance easier to carry out (pump inlet and exhaust isolation valves, purge
valves, etc.).
Installation
16/46

3. The O-rings located under the blanking plates are not compatible with all applications. Product
users or integrators are responsible for installing O-rings that are compatible with their ap-
plications.
4. Remove the blanking plates used to seal the inlet and exhaust ports.
5. Keep the blanking plates, screws and washers for reuse when transporting the pump.
6. Ensure that no screws, washers or other objects are dropped into the pump inlet.
7. Fit flexible tubes in the pumping line to reduce the transmission of vibration.
8. Perform a leak test on the entire pumping line after installation.
5.2.1 Connection on the pump inlet side
Make sure that the parts or chambers connected to the inlet of our products can withstand
a negative pressure of 1·10-3 hPa relative to atmospheric pressure.
To achieve the optimum pumping speed, make the pumping line as short and straight as possible
and ensure that its inside diameter is not narrower than the pump inlet flange inside diameter.
The product is not designed to withstand loads on its inlet flange which may compromise stability.
●Mechanically attach the vacuum chamber separately from the pump.
●Use only dry parts and clean, grease-free, dust-free pipelines.
●It may be necessary to install an inlet filter (particle filter or condensable filter).
●If necessary, install an isolation valve on the inlet which closes when the pump stops.
5.2.2 Connection on the pump exhaust side
DANGER
Risk of poisoning in case of contact with toxic substances and by-products generated by the
process
The vacuum pump, pumping line components and operating fluids may potentially be contaminat-
ed with toxic, corrosive, reactive and/or radioactive substances related to the process and harmful to
health.
►Always connect the pump exhaust to an exhaust extraction system.
Ensure that all components in the exhaust line have a maximum pressure rating that ex-
ceeds the highest pressure the pump can generate.
5.2.3 Connecting the purge circuit
The gas purge consists of injecting an inert gas into the pump.
In this manual, the inert gas will be called ‘nitrogen’, as it is the most commonly used gas. For more
information about the type of purge gas, contact your Pfeiffer Vacuum service center.
DANGER
Danger of death by explosion when pumping gases containing pyrophoric/flammable materi-
als
There is a risk of explosion if pyrophoric materials above the LEL (Lower Explosive Limit) are sent to
the pump.
►Ensure there is a sufficient flow of nitrogen to lower the concentration below the LEL.
►Provide an interlock to ensure that gas flow towards the pump is stopped if the nitrogen flow is
interrupted.
The effect of nitrogen injection continuity on the process
If an interruption to the nitrogen flow represents a serious risk for the process, it is advisa-
ble to control the nitrogen supply with an external system capable of taking over if the nitro-
gen circuit fails.
Installation
17/46

Version G
A gas purge circuit protects the low- and high-pressure ball bearings and dilutes trace amounts of corro-
sive gases.
The pump must be connected to a dry and filtered nitrogen supply that has the required characteristics
(see chapter “Nitrogen characteristics”).
1. Connect the neutral gas pipe to the 1/4 BSPT connector provided for this purpose (flexible or rigid
pipe supplied by the customer).
2. Install an isolation valve on the neutral gas injection circuit, as close as possible to the pump. This
enables the pump to recover its initial pumping performances when gas injection is not used.
3. The purge maximum pressure must not exceed de 300 hPa (relative).
5.3 Check that the installation is leaktight
When the product leaves the factory, product leaktightness under normal operating conditions is guar-
anteed. The operator must maintain this level of leaktightness, especially when pumping dangerous
gases. For more information concerning leak tests, please contact our service center.
1. Perform a leak test on the entire pumping line after installation.
2. Carry out regular checks to ensure that there are no traces of the pumped gases in the surround-
ing environment and that no air is entering the pumping line during operation.
5.4 Electrical connection
WARNING
Risk of electric shock due to non-compliant electrical installations
This product uses mains voltage for its electrical supply. Non-compliant electrical installations or in-
stallations not done to professional standards may endanger the user’s life.

thorized to work on the electrical installation.
►This product must not be modified or converted arbitrarily.
WARNING
Danger of electrocution by contact during maintenance or overhaul
There is an electric shock hazard in case of contact with a product powered on and not electrically
isolated.
►Before carrying out any work, set the main switch to O.
►Disconnect the power cable from the mains.
►Secure the installation correctly by tagging and locking (LO/TO) the system to prevent uninten-
tional re-engagement.
NOTICE
Risk of electromagnetic disturbance
Voltages and currents can induce a multitude of electromagnetic fields and interference signals. In-
stallations that do not comply with the EMC regulations can interfere with other equipment and the
environment in general.
►Use shielded cables and connections for the interfaces in interference-prone environments.
Electrical safety
The pump is equipped with an I/O main switch that isolates the product from the power line when it is in
O position.
The pump is equipped with a frequency converter in compliance with EC standards that allows the
pump to run automatically at high and low voltages. The frequency converter is protected against short-
circuits from power line. Once this safety process is activated, power is switched off and the pump is put
into a safe condition.
Installation
18/46

Procedure for restarting the pump after a power failure

Tbl. 1: Rotation speed
Influence of rotation speed on pump performances
Pump performances are guaranteed for a nominal speed of 100 Hz. Changing the rotation
speed affects the pumping speed and the ultimate pressure of the pump. At low speed, it is
the customer’s responsibility to find the correct settings according to the pump and the
process.
●Do not exceed the maximum frequency.
●Do not run the pump continuously at speeds ≤ 60 Hz.
