correctly affixed. The result is leaks or negative changes in the running properties.
►Observe the shape tolerances for the counter flange.
►Observe the maximum deviations in evenness across the entire surface.
Risks during operation
WARNING
Danger of death from poisoning due to toxic gases being expelled without an exhaust line
Exhaust gases and vapors are released from the turbo pumping station unhindered during normal us-
age. In the case of processes with toxic media, there is a risk of injury and danger of death due to
poisoning.
►Note the corresponding regulations for handling toxic substances.
►Toxic process gases should be safely conveyed away via an exhaust line.
CAUTION
Risk of injury from bursting due to high pressure in the exhaust line
Faulty or insufficient exhaust lines cause hazardous situations, e.g. increase in exhaust pressure.
There is a risk of bursting. It is not possible to rule out the risk of injuries due to broken pieces flying
around, high escaping pressure and damage to the equipment.
►Lay the exhaust line without shut-off units.
►Observe the permissible pressures and pressure differentials of the product.
►Check the exhaust line regularly for correct function.
NOTICE
Leaks may occur due to the incorrect installation of CF flanges
Inadequate cleanliness when handling CF flanges and copper seals results in leaks and may cause
process damage.
►Always wear suitable gloves before touching or fitting any components.
►Fit seals only if dry and free of grease.
►Note any damaged surfaces and cutting edges.
►Replace the damaged components.
NOTICE
Destruction of the pump due to gases with excessively high molecule masses
When conveying gases with non-permissibly high molecule masses, there is a risk of the turbopump
being destroyed.
►Make sure the gas mode is set correctly [P:027] on the electronic drive unit.
►Consult Pfeiffer Vacuum before using gases with larger molecule gases (> 80).
Safety
9/56

NOTICE
Damage to the turbopump due to nonpermissibly fast pressure rise during venting
Non-permissibly high pressure rise rates place a significant load on the rotor and the magnetic bear-
ing of the turbopump. During venting very small volumes in the vacuum chamber or the turbopump,
there is a risk of uncontrollable pressure rises. This causes mechanical damage to the turbopump,
including potential failure.
►Observe the prescribed maximum pressure rise speed of 15 hPa/s.
►Avoid manual and uncontrolled venting of very low volumes.
►Where necessary, use a venting valve from the Pfeiffer Vacuum range of accessories.
Risks during maintenance
WARNING
Danger of death from electric shock during servicing and maintenance work
The device is only free of voltage with the mains plug disconnected and the turbopump at a standstill.
►Switch off the main switch prior to starting any work.
►Wait for the turbopump to come to a standstill (speed = 0)
►Disconnect the mains plug from the device.
►Secure the device against accidental restart.
WARNING
Health risk and potential environmental damage due to toxic contaminated parts or devices
Toxic process media result in contamination of the devices or parts thereof. During maintenance work
there is a health risk due to contact with these poisonous substances. The non-permitted disposal of
toxic substances results in environmental damage.
►Take appropriate safety precautions and avoid health risks or environmental hazards due to toxic
process media.
►Decontaminate the affected parts before carrying out maintenance work.
►Wear protective equipment.
NOTICE
Malfunction due to changing the connection configuration
The pumping station connections are pre-configured at the factory. If the control lines on the connec-
tor are mixed up, this causes the pumping station to malfunction or fail.
►When removing components, note their original layout for subsequent re-assembly.
►Make a note of the accessories configuration and important setting values from the DCU before
disassembly of the pumping station or components.
Risks during recommissioning
NOTICE
Damage to the turbopump due to excessive aging of the operating fluid after recommission
ing
The storage capacity of the operating fluid in the turbopump is limited. Excessive aging of the operat-
ing fluid can result in the ball bearings failing and cause damage to the turbopump.
►Observe the usable service life of the operating fluid:
●Without operation, maximum of 2 years,
●Following operating and standstill times, 4 years in total.
►Observe the maintenance instructions and inform Pfeiffer Vacuum Service.
Safety
10/56

Risks in the event of faults
WARNING
Danger of death due to the turbopump tearing off in the event of a fault
Sudden blocking of the rotor generates high destructive torques in accordance with ISO 27892. If it is
not fastened correctly, the turbopump will tear off. The energy released in this way can propel the
entire pump or broken pieces from the inside of the pump through the room. Potentially dangerous
gases may escape. There is a risk of serious injury, potentially even fatal, and significant equipment
damage.
►Follow the installation instructions from the manufacturer.
►Observe the requirements for stability and the design of the counter flange.
►Only use approved original accessories or mounting elements approved by Pfeiffer Vacuum for
the installation process.
WARNING
Danger of death due to the turbopump with vibration damper is tearing off in the event of a
fault
Sudden blocking of the rotor generates high destructive torques in accordance with ISO 27892.
These result in the turbopump tearing off when using a vibration damper. The energy released in this
way can throw the entire pump or broken pieces from the inside of the pump through the space. Po-
tentially dangerous gases may escape. There is a risk of serious injury, potentially even fatal, and
significant property damage.
►Provide suitable safety measures on customer's side to compensate the torques arising.
►Please contact Pfeiffer Vacuum before installing a vibration damper.

5 Installation
The rotor of the turbopump revolves at very high speed. In practice it is not possible to exclude the risk
of the rotor touching the stator (e.g. due to the penetration of foreign bodies into the high vacuum con-
nection). The kinetic energy released acts on the housing and on the anchoring of the turbopump within
fractions of a second. This makes the stability of the turbopump and its fastenings extremely important.
Comprehensive tests and calculations conforming to ISO 27892 confirm the safety of the turbopump
both against crashes (destruction of the rotor blade) and against bursting (breakage of the rotor shaft).
The experimental and theoretical results are expressed in safety measures and recommendations for
the correct and safe fastening of the turbopump.
5.1 Preparatory work
Preliminary note
►Choose an installation location that permits access to the pumping station and to supply lines at
all times.
Prerequisites
●The given ambient conditions
●level, vibration-free surface
●Distance to side walls or adjacent devices: at least 50 cm
●Distance to free table edges min. 10 cm
●when using a housing heater and water cooling, the temperature on the connection flange on the
vacuum chamber is not permitted to exceed 120 °C
Choosing the installation location
1. Ensure adequate cooling options for the pumping station.
2. Install suitable protective shielding if ambient magnetic fields occur that are higher than the maxi-
mum permitted.
3. Install suitable protective shielding to prevent the radiated heat output exceeding the permissible
values when high temperatures arise due to the processes involved.
5.2 Setting up the pumping station
CAUTION
Cutting injuries on sharp and rotating parts with the high vacuum flange open during installa
tion
With the high vacuum flange open, access to sharp-edged parts is possible. There is a risk of cutting
injuries. Objects falling inside destroy the pump during subsequent operation.
►Only remove the original protective cover immediately before connecting the high vacuum flange.
►Do not reach into the high vacuum flange.
►Wear protective gloves during the installation process.
►Do not put the pump into operation with the vacuum flanges open.
►Ensure that the mechanical installation is completed before the electrics are connected.
General notes for the installation of vacuum components
►Choose an installation location that permits access to the product and to supply lines at all times.

5.2.1 Grounding the pumping station
Fig. 5: Example grounding terminal for a HiCube 80 Eco
Connecting the grounding
Pfeiffer Vacuum recommends connecting an appropriate grounding cable to divert applicative interfer-
ence forces.
1. Use the grounding terminal of the turbopump (M4 internal thread).
2. Perform the connection in accordance with applicable local regulations.
5.2.2 Anchor the pumping station (only applies to HiCube 300 Eco)
Fig. 6: Fasten the HiCube 300 Eco pumping station using securing straps
1 Securing strap 2 Securing hooks
Secure the HiCube 300 Eco against twisting
In the case of a sudden blocking of the turbopump rotor, the resulting torque must be taken up via the
pumping station frame by the fixture provided by customer. Anchoring the pumping station is mandatory
in order to secure the pumping station and the vacuum system. For this purpose there are 2 securing
hooks at the sides of the pumping station frame.
1. Always fasten the HiCube 300 Eco pumping station using securing straps to both securing hooks.
2. Fix the securing straps against the securing hook openings and thus against the direction of rota-
tion of the turbopump.
3. Fasten the securing straps at the customer's site such that they are able to withstand loads of up
to 2000 N per fixing point.
4. Ensure that the straps are correctly positioned and tensioned. The loop of each strap must be in
the hollow of the hook.
