•
Running a screwdriver with a handle diameter
of at least 20mm through the hose, handle first.
•
Hold one end of a 10 to 12 metre length of string
and vacuum the other end through the hose.
Switch off the power unit, and attach a brush
or other similar object to one end of the string,
pulling the string and object through the hose.
11. pVC ducting blocked
Check the airflow at the power unit. If there is good
flow there but not at all wall the valves, the pVC
ducting behind the wall may be cracked, broken
or blocked. you may need to call your service
technician.
If you prop open furthest wall valve and run the
power unit by shorting out its low voltage pins, you
may determine if you have a blockage or a break.
If there is little air flowing out of the power unit
exhaust, there is likely to be an obstruction in the
ducting rather than a break. you could try plugging
in the nozzle of a portable vacuum unit into a wall
valve which may suck out the obstruction.
12. dirt canister overflow
If you have a bagless Cyclonic power Unit, a full or
overflowing dust bin will impede the efficiency of
your unit resulting in poor performance.
while your system newly installed it is advisable
to check the dust bin regularly until you develop a
sense of how long it takes to fill the bin.
13. filter bag clogged
If you have a paper or cloth bag power Unit, a full
bag will impede the efficiency of your unit resulting
in poor performance.
while your system newly installed it is advisable to
check the bag regularly until you develop a sense
of how long it takes to fill the bag.
Very fine material such as concrete dust can clog a
bag very quickly. Vacuuming such materials is not
recommended.
If vacuuming of fine material is unavoidable, the bag
should be replaced immediately after the cleanup
is completed or during the cleanup if there is a loss
in performance while vacuuming.

14. dirt canister lid off
If your Vacuum power unit has a lid, the lid must
be placed squarely on the top of the dirt canister,
otherwise the vacuum will leak causing a reduction
or complete loss of suction.
15. dirt canister gasket loose
If the dirt canister gasket has been dislodged or is
loose, there will a be vacuum leak which will also
significantly reduce any performance. the seal may
need to be glued back into position.
16. outside exhaust blocked
If there is poor air flow at the end of the exhaust line,
but the air flow is better at the exhaust on the power
unit with the exhaust line removed, there will be a
blockage in that section of pVC ducting.
you may need to call your service technician.
17. dirt canister not latched
If your power unit has a latching clips on the lid or
dirt canister, ensure it is properly closed or latched,
as any leak will greatly reduce performance.
18. Wall inlet valve door open
only one inlet wall valve should be opened for use
at any one time. a slight opening or leak in any valve
other than the one you are using will greatly reduce
performance.
19. lint filter clogged
the lint filter located under the bottom baffle may
clog, causing poor performance, if the dirt canister is
overflowing or the bag has burst. this metal gauze lint
filter is easily accessible under the bottom baffle and
should be checked each time the bag is changed.
See page 17. Cleaning the lint Filter
20. relay stuck on
Some power units may have an internal relay, rather
than a solid state control board to switch the unit.
as mentioned in "9" above, if you have unplugged
the low voltage wiring, and the power unit still runs,
then you will need to switch the power unit off at the
power point.
Internal service to the power unit should only be
carried out by qualified persons. Please call your
service technician.
