2. Connect the motor supply cable (Using 4x0.75-1mm) between control board and Filter junction
box terminals. (Through flexible conduit g land)

E. OPERATION.
Motor synchronization must be carried out as follows :
a. Switch the [MAIN] switch to ON = 1 position and Verify that L1 [ON] indicator lights.
b. Press pushbutton [MANUAL FLUSH] momentarily and Verify that L2 [FLUSH] indicator lights
and the motor activated simultaneously.
Check the motor axis rotation (Which drives the filter dirt collector), The rotation must be at
the same arrow label direction.
If not , switch the [MAIN] switch to OFF = 0 position , and exchange between two of the
Motor phase and check again.(e.g. Between motor connection to TB 6-7 or TB 7-8 in the control
board or in the filter junction box.)
F. TIMERS FUNCTION.
TP - Differential pressure sense timer. (Factory set to 5 sec.)
Note that in case of differential pressure signal continuation the system will flush every TP
Time set.
TF – Flush timer. (Factory set to 10 sec.)
NOTE that the practical flushing time is the time required for the hydraulic piston to
Complete its movement due to a given line pressure. In order to minimize the flushing
Time/waste of flushed water set TF respectively.
TD – Interval flush timer. (Factory set to 10 hours & enabled - TB 13/14 shorted)
NOTE that the TD timer can be disabled by removing the short wire from TB 13/14-SET
inlets)
