10 Safety Device Operation
NOTE
: The vacuum has an overheating protection device.
It will automatically switch off power to the motor if it overheats. eg. from
blocked nozzles, full dust container or unclean filters.
If this happens, turn off the vacuum and unplug from power socket, clean
blockage and / or filters and allow to rest for at least 60 minutes which should
be enough time for the motor to cool down.
Note
: If the over-temperature device activates and turns the motor off, and
you do not unplug the appliance from the power point, the motor will restart
automatically after it has cooled down enough to reset the safety device.
11 Vacuuming – Wet Surface
Inside the vacuum cleaner is a float which rises as the dust canister fills
with water.
When the water level gets high enough, the float will block off the air
intake, which will be noticeable by the motor noise changing pitch, and
prevents any further suction.
At this point, the vacuum cleaner must be stopped, switched off and
unplugged before removing the dust canister for emptying.
12 Vacuuming – Dry Surface
During normal vacuuming, the water float will remain in the lower position
and will not interfere with the performance, however, should the vacuum
cleaner be knocked over on its side or top, the float will move and may
block off the air intake.
This will be noticeable by the motor noise changing pitch, and prevents
any further suction.
If this happens, the vacuum cleaner motor needs to be turned off, the
vacuum cleaner up righted and then the motor can be restarted.
