Typical Installation Drawing
Start-up and first operation
1.
Make sure all the electrical cables are properly wired according to the relevant drawings.
2.
Turn on control power and 24VAC but leave OL protector off. Verify that the limit switches are wired correctly by
manually toggling them. Monitor the appropriate inputs according to the wiring diagram accompanying the control
panel. Proceed to next step only after verifying correct wiring of all limit switches in the system.
3.
CHECK ROTATION: The suction scanner shaft should turn clockwise (CW) and move towards the filter housing until it
reaches the inner limit switch (BLS). If the motor rotates in the opposite direction (CCW), turn off the power
immediately and change the direction of the motor rotation by changing the phase order. (By authorized electrician).
4.
The motor must stop when the limit switch plate reaches the limit switch (opening the NC circuit).
5.
Operate a "dry" flushing cycle by pressing on the "TEST" push button. Check that the flushing cycle runs as described in
the “Self
-
cleaning process” p
aragraph in this manual.
6.
Open the inlet valve to the filter, leaving the outlet valve closed or with an open by-pass valve (This will keep the flow
through the filter to a minimum), and initiate a flush cycle.
7.
Check that the exhaust valve opens, and all stages of the flushing cycle perform properly.
Attend to leakage, if any.
8.
Close the 1/4" valve at the low-pressure sensing port and drain the low-pressure side of the PDS.
The instrument should switch ON and after 5 seconds, flush cycle should start.
Re-open the 1/4" valve.
9.
Gradually open the outlet valve and/or close the by-pass valve. Operate the filter under the designed hydraulic
conditions.
10.
Set the flushing interval timer for 6-8 hours.
11.
Check and re-tighten all bolts after the first week of operation.
