Solenoid Removal & Installation (Figure 5)
The solenoid hydraulically controls the flushing valve's operation.
1. Remove the 4 screws attaching the electronic control unit cover, disconnect and remove the
9V battery.
2. Disconnect the solenoid control tubes.
3. Remove the fittings from the damaged solenoid.
4. Disconnect the electrical wiring from the control card terminals (white (+), red (o) and
black (c) wires).
5. Remove the nut from the solenoid lower section.
6. Pull the solenoid out of the control assembly.
7. Insert a new solenoid into the control assembly.
8. Install the nut on the solenoid lower section.
9. Install the fittings on the ports of the new solenoid.
10. Connect the electrical wiring to the control card terminals (white, red and black wires)
(See Figure 5).
11. Connect the solenoid control tubes.
12. Connect the 9V battery according to the correct polarity and secure the electronic control unit
cover with the 4 screws.
WARNING
Take precautions while operating the filter as the filter may enter a flushing
mode automatically, without prior warning.
13. For AC controlled filter, refer to Appendix 1.
14. Perform a flushing cycle by disconnecting the low pressure tube from the differential pressure
indicator (closing of the electrical circuit) – re-connect it immediately as flushing starts.
15. Verify that the hydraulic flushing valve closes after 5 seconds.
16. Perform an additional flushing cycle manually, by operating the handle (turn clockwise 90
°
)
located on the solenoid (See Figure 3).
