Thermal protector
An internal thermal protector has been
used in your cleaner to prevent over-
heating if a large item or clog gets
caught in the nozzle or at the opening of
the bag.
When the blockage is not removed,
the thermal protector will trip and
cleaner will stop running.
If this happens, turn cleaner OFF and
disconnect cleaner from electrical
outlet.
Then disconnect nozzle and
remove obstruction. Within 15 minutes
the thermal protector will cool and auto-
matically reset and cleaning may
resume.
If cleaner does not operate, allow addi-
tional time for thermal protector to reset
.
