●
Do not carry out any unauthorised modifications or conversions to the pumps.
●
Depending on the operating and ambient conditions, the surface temperature of the
pumps may rise above 70 °C. Use suitable finger guards if necessary.
●
When returning the pumps to us please note the instructions in the Service section.
The following safety instructions are only valid for the disassembly of the drive
system for a vacuum pump with a magnetic coupling:
●
When disassembling the drive system from the pump housing, the strong magnetic
field may influence the function and operational reliability of electrical and electronic
devices.
●
Persons with cardiac pacemakers must keep away from the magnetic coupling.
Danger to life
!
–
Minimum distance: 2 m!
●
Disassembled magnetic couplings must be kept away from computers, data storage
media and other electronic components.
●
Keep the disassembled components of the magnetic coupling separate at all times.
Danger of crushing!
●
Do not allow any magnetised parts into the vicinity of the magnetic coupling. Danger

2.2 Protective equipment
Determined situations concerning the handling of vacuum pumps require wearing of per-
sonal protective equipment. The owner, respectively the employer are obligated to pro-
vide adequate equipment to any operating persons.
Duty to inform
Each person involved in the installation, operation or maintenance of the vacuum pump
must read and observe the safety-related parts of these operating instructions.
The operator is obligated to make operating personnel aware of dangers originating
from the vacuum pump, the pumped medium and the entire system.
DANGER
Danger to health by hazardous substances during maintenance or installation
Depending on the process vacuum pumps, components or operating fluids can be con-
taminated by toxic, reactive or radioactive substances.
Wear adequate protective equipment during maintenance and repairs or in case of
reinstallation.
CAUTION
Risk of injury through hot surfaces
Vacuum pumps can become hot during operation.
Allow the pump to cool before maintenance and repairs.
If necessary wear protective gloves according to directive EN 420.
