5.5 Problem: Frequent or continuous flushing while filling main pipeline.
POSSIBLE CAUSES
1. Downstream pressure is not available to provide vacuum cleaning power.
2. Rapid-filling flow rate exceeds the controllers' pressure differential.
SOLUTION
Partially close downstream mainline valve; filter gauges should read 25 psi.
P
OSSIBLE CAUSE
Filter may have been shut down "dirty,” with a contaminant that is difficult
to remove after it dries on the screen.
SOLUTION
A super flush needs to be performed as follows: a downstream mainline
valve should be adjusted providing that the static pressure against the valve
does not exceed 80 psi. After the valve is adjusted, cycle the filter through
several "long" flushings. This process uses the entire available differential
pressure in the filter cleaning process.
5.6 Problem: Frequent flushing during normal operation.
POSSIBLE CAUSE
Very dirty water.
SOLUTION
Increase flushing time to 6 seconds or more.
POSSIBLE CAUSE
The controller pressure differential is set too close causing vibration to initiate
a flush cycle.
SOLUTION
Increase pressure differential (see Page 2 for both electronic ant hydraulic
controller).
