Notes:
•
” on page 28 for configuring the system for a new system or a
process change to an existing system.
•
This procedure is based on a typical pressure controlled feed pump. Other setups may
require slight alterations.
•
For proper operation of the SC-150 skid, it is important that there be no air within the
system. Each time the system is started, the air should be bled from the system.
1. Inspect the system to ensure it is ready to start:
•
Make sure the controller is powered, but in the standby state.
•
Make sure that all downstream processes and drains are prepared to receive water.
•
Make sure all upstream processes are active or in standby, and prepared to deliver water.
2. Make sure all valves are closed; filtrate valve, purge valves, inlet valve, service valves, etc.
3. Open the air and high pressure bleed valves. Make sure all downstream valves from the bleed
valve (if any) are open. (Note that the main service drain valve is upstream from the air bleed
tubing, and it must remain closed.)
4. Ideally, the skid should be gravity bled with low
pressure (2-4 psi feed) by allowing water to flow
through inactive feed pumps. If the feed water
supply is below the skid and the feed pump must
power bleed, care must be taken to reduce any
pressure surges and water hammers.
5. Touch the AV icon on the home screen. If using
gravity to bleed the system then press the Air Bleed
button
6. Slowly open the feedwater inlet valve just enough to permit a small amount of water into the
system to expel air through the air bleed tubing.
7. Continue bleeding the system until no more air is present at the air bleed, and then close the air
and high pressure bleed valves.
8. If power bleeding, release the feed pump Manual On button and press the Done button to clear
the pop-up screen.
9. Make sure the feedwater service valve is fully open.
10. If the Home screen is not displayed, press the Home icon.
11. Press the Start button and confirm (Yes) to begin the startup event.
12. During the startup event, air must be bled from the low-pressure line. After the system has met
the minimum RPM setpoint, open the low-pressure bleed valve for a short time until all air is bled.
•
NOTE: this will bleed air on the “clean” side of the filter so adequate cleaning assembly RPM
must be confirmed before opening this valve. Failure to do so will cause premature plugging of
the filter.
