Flushing after Foam Operation
ATTENTION !
To ensure the pump operates without malfunctions, it is important
to flush the system parts (pressure outlets) which are in touch with
a water-foam mixture.
- Operate the pump system as mentioned in the
◊
"Tank Suction Operation" or
◊
"Drafting Operation from Open Water Source" or
◊
"Hydrant / Supply Operation" chapters.
- Keep all proportioner valves (J87)/(J87_)* closed.
- Open the pressure outlets that have been in use with a water-
foam mixture.
- Flush the roof turret:
◊
Operate the roof turret with water as mentioned in the "Roof
turret Operation with water" chapter.
- Open flushing valves (J164/1) for the water-side pressure
gauges.
- Increase pump pressure to approx. 5 bar.
- Carry on flushing until clean water is discharged.
- Before completion of flushing, flush the priming pump:
◊
Reduce pump speed to idle (pump pressure below 2 bar).
◊
The priming pump will engage automatically.
◊
Carry on flushing until clean water is discharged.
ATTENTION !
The Flushing procedure must be done carefully after each foam
