TROUBLESHOOTING
Red LED Flashing
The pre-filter and/or main filters may be blocked.
One or all of these filters may be blocked. Unless recently
changed you should first clean then replace the pre-filter and
re-start the machine. If the red LED (or audible alarm) does not
switch off you should then replace the main filter. If these filters
have been recently changed then another fault may be causing
the LED to illuminate. See below.
If the filter blocked alarm continues after filters have been certified
Connecting hose may have a leak.
Check all hose, seals and connections for leaks.
The alarm has triggered and the blower stops.
The thermal cutout on the blower may have engaged. Turn off the
power to the machine. Check the cooling vents both inside and
out. Switch off mains power and allow the blower to cool. If this
does not remedy the fault please contact your supplier.

Filter Faults
Odour or particles in exhaust air.
The main filter may be damaged, fitted incorrectly, missing or
the chemical section of the main filter may be exhausted. Check
main filter and replace if necessary.
Airflow insufficient to remove fume when the filter is not blocked.
Possible airflow leak or a blockage. Check all hose, seals and
connections for leaks. If OK then increase airflow level. If not OK
contact your supplier.
The main filter has a shorter than expected life.
Large particles may be bypassing the particle pre-filter. Check the
