Risks during installation
DANGER
Danger to life from electric shock
Contact with exposed and live elements generate an electric shock. Incorrect connection of the mains
supply leads to the risk of live housing parts that can be touched. There is a risk to life.
► Before the installation, check that the connection leads are voltage-free.
► Make sure that electrical installations are only carried out by qualified electricians.
► Provide adequate grounding for the device.
► After connection work, carry out an earthed conductor check.
WARNING
Risk of crushing from rotating parts
Fingers and hands may be caught by rotating pistons within the connection flange. This results in se-
vere injuries.
► Keep limbs out of the reach of the roots pump.
WARNING
Risk of scalding from suddenly escaping hot cooling water
The cooling water connections are open to both sides. When connecting the cooling water supply,
there is a risk of scalding from the sudden escape of overpressurized hot water.
► Prior to installation, ensure that pressure is discharged from the cooling water system, and that it
is cooled down.
► Wear protective equipment, e.g., safety goggles and gloves.
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.
CAUTION
Risk of injury from loss of stability
During setup, there is a risk of injury from tipping, if the vacuum pump is not anchored on the stand-
ing surface.
► Secure the vacuum pump using suitable lifting gear.
► Wear personal protective equipment.
CAUTION
Danger of injury from moving parts
After a power failure or a standstill as a result of overheating, the motor restarts automatically. There
is a risk of injury to fingers and hands if they enter the operating range of rotating parts.
► Safely disconnect motor from the mains.
► Secure the motor against reactivation.
► Dismantle the vacuum pump for inspection, away from the system if necessary.
