Safety instructions for product removal
Maintenance must be performed by a skilled maintenance operator
trained in the relevant health and safety aspects (EMC, electrical hazards,
chemical pollution, etc.).
Isolate the product from all energy sources (mains electricity, compressed air,
water, gas ...) before starting work.
Standard precautions before any maintenance operation:
Before performing a maintenance operation, stop the pump. When the pump
is at rest, switch off the pump by setting the controller main switch to «0»,
wait 5 minutes before disconnecting the main cable. If this last one remains
connected, some components will still be energized.
Be sure that the controller status is visible from the operator otherwise
disconnect the cable from the pump.
Risk of injury by cutting:
The inlet of the pump musn’t be disconnected as long as the rotor is moving
and without having disconnecting the power line cable.
After pumping on corrosive or toxic gases, it is strongly recommended to
seal the pump with blanking plates in case of return to the repair service
centers (
E 100). Don’t forget to label in a visible way the product for the
operator.
Risk due to pumping conditions:
Remaining process gases in the pump may cause severe injury or death.
Before removing the pump from the installation, continue N2 flow from the
process tool for 30 min. Nitrogen pressure and flow rate should be identical
to the programmed values during process.
Chemical supplies coming from the tool, as well as the water and the
nitrogen need also to be locked out / tagged out.
During pump removal, operator could be in contact with process residues
on the inlet and exhaust ports which could cause severe injury or death. Ask
your safety department for instructions according to the local regulations.
