SECTION 9 - TROUBLESHOOTING
A malfunctioning filter can be found in one of the following modes:
Section 9.1 - The filter does not experience rinse cycles (automatic or manual).
Section 9.2 - The filter rinses continuously (rinse valves do not close).
Section 9.3 - The filter cycles continuously (rinse valves open and close
repeatedly).
Section 9.4 - Controller inoperative.
Listed below are steps to be followed in troubleshooting the filter to determine the cause
of the situation. Prior to proceeding with the following, all tubing connections should be
verified against the schematics provided on pages 9 - 13 of this manual.
9.1 - The filter does not experience rinse cycles (automatic or manual).
1. Check the differential pressure across the filter versus the preset on the differential
pressure switch. If the differential is higher than the preset, go to step 5.
(NOTE: All differential pressure switches are factory preset for 7 psig increasing).
2. If the differential is lower than the preset, monitor the differential pressure across the
filter to determine whether it is increasing. If it is increasing, allow the differential
to increase to the preset value and monitor operation.
3. If it is not increasing, or is increasing very slowly, shut down the filter and extract the
fine screen. Carefully inspect the screen and o-rings for damage. Replace parts
as necessary. When reinstalling the screen, check to ensure that it is seated
properly inside the housing and that the dirt collector moves freely.
4. If the screen is intact and was seated properly, then the screen openings (micron
size) may be too large for the particular application. Contact your Orival
representative for assistance.
5. If the differential is higher, check to ensure that the Controller power switch is on.
6. Close the isolation valve on the filter outlet and allow the inlet and outlet pressures
to equalize. Initiate a manual rinse cycle by depressing the rinse cycle button. If
the filter rinses, check the differential pressure switch and connections and
repair or replace as necessary. Recheck operation. Go to step 11.
7. If the filter does not rinse, check to ensure that the solenoid valve is being
energized. (most standard valves have a small light illuminated when energized).
Repair or replace as necessary.
8. Check to ensure that the solenoid valve is attempting to drain the top chamber of
the manifold by observing its flow to the drain. If not, check for blockages in
the solenoid valve.
