Install the accessories
WARNING:
When fitting accessories inside the enclosure, ensure that the pump is switched
off. Lockout and tagout the electrical supply before removing the enclosure
panels.
WARNING:
The surfaces of the dry pump, booster (if fitted) and spools are very hot when
the dry pumping system is running. Allow these surfaces to cool to safe
temperatures before installing the accessories inside the enclosure. Be sure to
route and secure accessory cables as shown in their installation manuals to
prevent the cables from resting on hot surfaces.
Refer to the individual accessories manuals for installation information.
6.12.
Commission the dry pumping system
WARNING:
During some application cycles, the dry pumping system may exceed the OSHA
1910.95 Occupational Noise Exposure Limits, the EU noise directive
2003/10/EC or other regional noise limits dependent upon the process, duty
cycle, installation or environment in which the dry pumping system is being
operated. A sound pressure survey must be conducted after installation. If
necessary, the controls must be implemented to ensure that the relevant limits
are not exceeded during the operation and that adequate precautions are taken
to prevent the person from exposure to the high noise levels during the
operation.
1.
Before starting the pump, the main power supply should be connected
correctly and cooling water and purge gas need to be checked.
2.
Switch on the cooling water and purge gas supplies.
3.
Ensure that the exhaust extraction system is not blocked (for example, that
valves in the exhaust extraction system are open).
4.
Ensure that all openings to atmospheric pressure in the foreline vacuum
system are closed.
5.
Either connect the main power supply or install the run button (1x6:6 and
1x6:7).
6.
If the dry pumping system starts and continues to operate, continue at step 8.
