Troubleshooting
Problem
Probable Cause
Recommended Action
Pressure does
not consistently
reach correct
range (too low)
during
commissioning
procedure
Leakage between
pump and Automist
head
Check for leakage on the high pressure water path, for
example the quick-fit connector may not be secured or its
o-ring may not have been fitted.
Re-run commissioning.
Blockage at the pump
inlet
Close off the water with the isolation valve.
Disconnect the hose at the pump inlet and check for
blockages on the pump strainer and within the inlet hose.
Incorrect Nozzle
specification
Check to see the correct specified nozzles have been
installed
(nozzle “A” numbers should sum to 32 on each
pump, where present).
Please contact your Automist supplier.
Mains pressure or
flow is too low
Close off the water with the isolation valve and disconnect
the hose.
Verify that the water mains connection can supply at least 6
litres per minute (lpm) of flow and if possible check that the
static inlet pressure is at least 1 bar.
If the flow is close to or below 6 lpm, the mains pressure
may be too low for Automist to operate correctly, or there
may be constrictions in the water supply. A plumber should
be called to resolve the issue.
