Rivulis F2400 Media Filter
6. PERIODIC CLEANING
Close valves at the inlet and outlet of filters.
Release pressure within the filter and open the top filling port.
Inspect media level and its cleanliness.
If the media is not effective anymore (long usage, or tough caking), replace the media, see
“replacing the filter’s media”.
Check the valves. Check the Flow Limiting Valve or throttling valve.
7. MAINTENANCE
Perform monthly periodic checks.
Once a week perform a manual back flush, make sure that the differential pressure is below
0.25 bar (4 psi), after the back flush.
Once a year spread a layer of grease on the top cover's handle threads.
Special coating protects all Rivulis products; any damage to the protective
coating of the equipment must be repaired without delay. Prior to the
application of the protective paint, clean thoroughly the damaged areas with a
wire brush.
Replace batteries in the controller, if applicable, with fresh ones at the
beginning of the irrigation season.
Before installing back bolts, spread bolts threads with thin layer of grease.
The array should be disinfected by chlorination at the beginning and end of each irrigation
season. Chlorination Process:
1. Close the array’s inlet and outlet valves.
2. Empty the filters half full of water. If the array is completely dry, first fill the filters half full of
water, and then add the liquid Sodium Hypo-chlorite (NaOCl) to each filter, according to the
table below.
3. Add water to each filter to 10 centimeters (4") above the media surface layer and close the
upper inlets. Each filter will contain a concentration of 80 -100 ppm of liquid Sodium Hypo-
chlorite.
4. Wait for 30 minutes (no water flowing), then perform two backwash cycles to each of the
array’s filters – without opening the outlet valve.
