WARNING
Risk of injury due to incorrect installation
Dangerous situations may arise from unsafe or incorrect installation.
► Do not carry out your own conversions or modifications on the unit.
► Ensure the integration into an Emergency Off safety circuit.
WARNING
Danger of cut injuries from unexpected start up.
The use of mating plugs of the electronic drive unit (accessories) enables the automatic run-up of the
vacuum pump as soon the power is turned on. Attaching mating plugs before or during the installa-
tion leads to the movement of parts hence the risk of cut injuries by sharp-edged in the exposed high
vacuum flange.
► Only connect mating plugs after the mechanical installation.
► Only switch on the vacuum pump immediately prior to operation.
CAUTION
Danger of burns on hot surfaces
Depending on the operating and ambient conditions, the surface temperature of the vacuum pump
can increase to above 70 °C. If access to the vacuum pump is unrestricted, there is a danger of burns
due to contact with hot surfaces.
► Install suitable touch protection if the vacuum pump is accessible to untrained persons.
► Allow the vacuum pump to cool down before carrying out any work.
► Contact Pfeiffer Vacuum for suitable touch protection in system solutions.
Risks during operation
WARNING
Risk of burns on hot surfaces when using additional equipment for heating during operation
The use of additional equipment for heating the vacuum pump or for optimizing the process gener-
ates very high temperatures on surfaces that can be touched. There is a risk of burning.
► If necessary, set up a contact guard.
► If necessary, apply the warning stickers provided for this at the danger points.
► Ensure adequate cooling down before working on the vacuum pump or in its vicinity.
► Wear protective equipment, e.g., gloves.
WARNING
Risk of serious injury in the event of vacuum pump destruction due to over pressure
Gas entry with very high over pressure results in destruction of the vacuum pump. There is a risk of
serious injury due to ejected objects.
► Never exceed the permissible 1500 hPa (absolute) inlet pressure on the suction side or the vent-
ing and sealing gas connection.
► Make sure that high, process-related over pressures cannot directly enter the vacuum pump.
CAUTION
Risk of injuries due to contact with vacuum when venting
While venting the vacuum pump there is a risk of minor injuries due to the direct contact of body parts
with the vacuum, e.g. hematomas.
► Do not fully unscrew the venting screw out of the housing during venting.
► Keep a distance from automatic venting device, such as venting valves.
