CONDITION
POSSIBLE CAUSE
SOLUTION
F
Pump capacity too low
Check the pump to make sure it is
working correctly. Check the plumbing
system for any obstructions. Reduce
Agitation Volume.
G
Pump capacity too high
Some centrifugal pumps provide more
fl
ow than necessary for the application.
A throttle valve is sometimes required to
restrict the
fl
ow coming from a centrifugal
pump.
Increasing bypass and agitation volumes
can also help when
fl
ows are too high to
reach the target application.

Make sure there is no pressure in the
system.
Remove the
fl
ow meter from the
discharge line. Inspect the inside of
the meter for obstructions. The turbine
should move freely. If it does not rotate
easily, try
fl
ushing it out with clean water.
If it remains stuck, remove the turbine
by releasing the retaining clip. Clean the
turbine carefully and make sure it rotates.
Replace the turbine into the
fl
ow meter
body and secure with the retaining clip.
If you have a rapid check
fl
ow meter,
remove the turbine from the
fl
ow meter
body by unthreading it at the sensor.
Check the turbine for obstructions.
Flush with clean water or disassemble if
necessary.
Check to ensure that the sprayer pump
has been engaged while trying to spray.
Check cabling for any loose connections.
