6. Installation & Start-up
Installation
A.
Check for any transport damage (The System operates under pressure!).
B.
Make sure that the inlet and outlet orientations are correct (shown by arrows on The System).
C.
Connect the Inlet, Outlet, Drain with theirs valves to the Main manifolds.
D.
Verify that all the covers clamps are properly closed !.
E.
Connect and check the pressure source to the command solenoids of the PLC/Controller.
F.
Connect the Air pressure source to the Accumulator.
Start-up Operation
•
If possible do a dry test run (once or more) on all the system to be sure all connections and wiring are
ok.
•
Run the System by slowly open the inlet valve letting the Air from the system to vent out from the Air
Release Valve on top of the Inlet manifold.
•
Once the Air vents, check for leakages that can happen during transportation and installation.
•
If the pressure difference is high, verify that the flow rate is not too high. An excessive flow rate
through the filter causes excessive pressure loss.
•
Open the Air supply and check the Air pressure in the Accumulator tank.
•
Manually Start a back-flush cycle and make sure that all system components function correctly.
•
If after the Back-flush the pressure difference is not reduced check if the flow is not too high, or the Air
supply is too low (pressure/flow).
Note:
PLC/Controllers are varied according to the Order.
PLC/Control
•
Refer to the manufacturer’s handbook before installing the PLC/Controller.
•
Make sure that the voltage is correct BEFORE connecting it.
•
Check that the ∆P hydraulic switch HIGH and LOW pressure tubes are correctly connected to the
appropriate ports.
•
Set the DP switch to the required ∆P (Recommended ∆P will be 5m/ 7PSI according to the site
conditions).
•
Set the PLC/Controller Back-flush Time to 7 seconds, Valve Delay to 1 second and the Dwell time to 25
seconds. These settings may require adjustment to conform to local water conditions. Typically, a 1 to
3 hour interval between back-flushes cycles is recommended.
•
Typically the Back-flush Cycle Time is a backup for the DP switch, it work in a way that whichever come
first reset the back-flush Cycle Timer.(Manual override will reset it too).
