Start-up and first operation
1.
Make sure all the electric wiring is correct, according to the enclosed drawings.
2.
Switch ON the control & 24V circuit breakers and the motor protector O.L. The motor will start operating *.
3.
CHECK ROTATION: The suction scanner shaft should turn clockwise (CW) and move towards the filter housing until it
reaches limit switch "A". If the motor rotates in the opposite direction (CCW), turn off the electricity immediately and
change the direction of the motor rotation by changing between two phases.
4.
The motor must stop when the limit switch plate reaches limit switch "A" (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” paragraph 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 operate a flushing 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 of the pressure differential switch for 5 seconds. The PDS hand will
move to the red area and the filter will start the flushing process. 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 (T1) for 6-8 hours.
11.
Check and re-tighten all bolts after the first week of operation.
When using Control board type "C" (Relay type) it is necessary to press the "Test" push button in order to start the motor
operation for the first time.
