WARNING: USE PROTECTIVE EQUIPMENTS
Risk of injury
. During some applicaon cycles the system can possibly exceed OSHA
1910.95 Occupaonal Noise Exposure Limits, the EU noise direcve 2003/10/EC or
other regional noise limits. The noise level depends upon the process, duty cycle,
installaon or environment in which the system is being operated. A sound pressure
survey must be conducted aer installaon. If necessary, set up controls to make
sure that the relevant limits are not exceeded during operaon and that precauons
are taken to prevent personnel from exposure to high noise levels during operaon.
WARNING: HOT SURFACES
Risk of burn injury
. The pump exhaust will heat up when the pump is in operaon. Do
not touch the pump surface.
Refer to Figure: Front panel controls:
1. Switch on the external electrical supply and check that the POWER LEDs illuminate.
If the Light-Eming Diodes (LEDs) do not illuminate, contact us.
2. Switch on the cooling water and nitrogen supplies.
3. Make sure that the exhaust ex
tracon system is not blocked (for example, that
valves in the exhaust extracon system are open).
4. Make sure that all openings to atmospheric pressure in the foreline vacuum system
are closed.
5. Press the Local Control buon and check that the green Local Control LED
illuminates and then remains connuously illuminated.
6. Press Start buon.
7. If the dry pumping system starts and connues t
o operate, connue at Step 8. If a
warning or alarm condion is indicated:
▪ Shut down the system: refer to Shut down on pag
e 62.
▪ Contact us.
8. Monitor the pressure gauge in the inlet pipeline:
▪ If the pressure is increasing, immediately shut down the system and contact
us.
▪ If the pressure is decreasing connue a
t Step 9.
9. Aer commissioning the system:
▪ To connue to operate the system, refer to Start-up on page 59.
▪ Otherwise, shut down the system, refer to Shut down on page 62.
