Blower not Running
Symptoms Corrections
Power cut If temporary (24/48 Hours) do nothing. If extended, obtain
alternative source of power or tanker sewage away.
Important: on power being returned to three phase supplies check
for correct rotation of blowers
Power supply fault Switch off blowers check fuses and any RCD breakers, on 3-phase
supplies check for correct rotation. Switch blowers to on and the
blowers should start. If not switch off and call electrician.
Blower overload has
tripped
Check for any obvious causes, reset overload and switch to on.
Blowers should start, if not switch off and call an electrician.
Blower runs
intermittently
Check that the cooling fan is running and the air ducts are clear, as
overheating in the cabinet will cause the high temperature trip to
switch off the power to all but the fan and beacon if fitted. Replace
fan if it has failed. Temporary solutions if the weather is fine: leave
the kiosk door open but ensure that no one can gain access to
electrical or rotating mechanisms.
No air bubbles showing on the surface of the filter section
Symptom Corrections

If the plant has been flooded due to high water level or other
cause the 'V' notches may have become blocked these should be
