Installation
– Physical forces from the piping system must not be allowed to act on vacuum
pumps.
Î
Lay piping from the pump sloping downward so that no condensate can flow
back into the pump; otherwise fit a condensate separator.
– If an air trap is created in the system, then a device for draining condensation
water must be provided at the lowest point.
5.5 Connecting to the mains power supply
Î
Plug the mains cable into the the mains connection on the rear side of the pum-
ping station and fix it with the clip.
Î
Connect the mains cable to the mains.
5.6 Connecting accessories
• An air cooling unit is integrated in the casing of the pumping station and is sui-
table for ambient temperatures up to +35 °C.
• A venting valve is installed and connected to the turbopump.
Î
Generally use water cooling if the ambient temperature is > +35 °C.
Î
Connect additional accessories according to the operating manual of the turbo-
pump.
WARNING
Ensure safe electrical installation
Safe operation after installation is the responsibility of the operator.
Î
Do not independently modify or change the pump and electrical equipment.
Î
Make sure that the system is integrated in an emergency off safety circuit.
Î
Always ensure a safe connection to the protective earthing conductor (PE, protection
class I).
Î
Consult Pfeiffer Vacuum for special requirements.
NOTE
Installation and operation of accessories
Pfeiffer Vacuum pumps can be equipped with a series of adapted accessories. The
installation, operation and maintenance of connected devices are described in detail in
the operating instructions of the individual components.
Î
For information on the operating instructions of components, see "Accessories".
Î
Use original accessory parts only.
CAUTION
Dangerous excess temperatures
Process-related high temperatures can result in impermissible excess temperatures
and thus damage to the turbopump.
Î
Always use water cooling when a casing heating unit is used or when the pump is
connected to a heated vacuum chamber.
