Connect and set up the cooling water

Water only flows if the pump is running or for about 10 seconds when the pump is first energised. The water
circulation system may be damaged if it cannot tolerate a no flow condition.
Notes: 1. For optimum water cooling, ensure that the cooling water supply meets the specification given in
Section 2.6. Ensure water supplies are connected in parallel. Refer to
recommends that quick connectors be used to reduce the risk of water spillage during connection/
disconnection.
2. For minimum water consumption, regulate the cooling water flow to the system. For this purpose, a
Constant Flow control water valve kit is available as an accessory. Refer to
Use the following procedure to connect the cooling water supply and ensure that the system is receiving the correct
water flow rate. Before starting the procedure, ensure that the electrical power supply to the system is switched off.
1. Connect the supply and return hoses to the pump.
2. Turn on the cooling water supply.
3. Switch on the electrical power to the system. The water valves in the pump cooling system will automatically
open in a pre-determined sequence.
4. Inspect the water hoses, pipelines and connections and check that there are no leaks.
Turn off the water supply while completing the remainder of the installation procedure.

Commission the system

During some application cycles it is possible that the system may exceed 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 pumping
system is being operated. A sound pressure survey must be conducted after installation and, if
necessary, controls implemented to ensure that the relevant limits are not exceeded during
operation and that adequate precautions are taken to prevent personnel from exposure to high
noise levels during operation.
1. Switch on the external electrical supply and check that the POWER LEDs
go on. If the LEDs do not go on, contact Edwards.
2. Switch on the cooling water and nitrogen 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. Press the LOCAL CONTROL button
(Figure 2, item 6) comes on and then remains continuously illuminated.
