Troubleshooting
Problem Possible Cause Solution
The filter does not flush Valves are closed Open valves
Pressure differential is not correct Perform a manual flush as follows:
1.
Close the filter outlet valve
2. Check that the filter outlet and inlet pressures are
equal
3. Perform a manual flush as in item 7, page 9.
4. Check the pressures at the inlet valve and in the
rotor chamber
Excessive pressure in the
rotor chamber
Drain pipes are not clear Check if drain lines are clear. If necessary replace with a
larger (diameter) flush drain line, or shorten the existing
lines.
Insufficient inlet pressure
(less than 2 bar—30 psi)
Inlet valves not fully open Open inlet valves to maximum.
Increase the inlet pressure or throttle the outlet to
increase pressure during the flush cycle.
Pressure differential exceeds
0.7 bar (10 psi) during
normal operation
Coarse filter is blocked Check coarse filter
Water does not flow through
the filter
Inlet lines blocked Check inlet lines
Isolating valves are closed Open isolating valves
