2. Low flow
3. Dirty filter requires rinsing and backwashing
4. Pump has blocked.
5. Inlet line is blocked.
6. Pump is not primed.
7. Incorrect water chemistry. Check pH and other water readings.
Check UV is working correctly (replace UV bulbs older than
6 - 12 months).
8. Clogged or channelled media. Perform an extra long rinse and
backwash.
Short filtration
cycles
Too much algae. Excessive water flow and pressure.
Check pump size. Overloaded with fish. Excessive feeding.
Filter blocked through calcium.
Above normal
or excessive
force is needed
to operate the
multi-port valve
Scoring or jamming with foreign matter or debris. If this condition
persists after rinsing, disassemble the valve to clear. Continued
operation may result in leaking due to damage to the multi-port
valve (spider gasket). See dealer or installer.
Filter media has
gelled / stuck
together
• Switching the Air Blower ON and OFF 2 or 3 times and performing
multiple rinses can free up media.
• Performing a backwash prior to following the cleaning instructions
can free up the media.
• Operating the filter on re-circulate will determine if the restriction
is in the filter.
• If you don’t succeed when following the two points above,
switch off the pump, isolate and drain the filter. Manually drain
the filter, remove the lid and inspect the inside of the unit.
The media may need to be removed and cleaned.
