check fuses and circuit-breaker (if
any).

If the fault cannot be rectified, please
contact a qualified service technician.
Safety cut-out
(applies to units with electric heater)
If the installation is protected by
means of a safety cut-out, which trips
when the appliance is connected, this
may be due to moisture in the heating
element. When an appliance containing
a heater element has not been used
for a long period or stored in a damp
environment, moisture can enter the
element.
This should not be seen as a fault, but
is simply rectified by connecting the
appliance to the mains supply via a
socket without a safety cut-out, so that
the moisture can be eliminated from
the element. The drying time can vary
from a few hours to a few days. As a
preventive measure, the unit should
occasionally be run for a short time
when it is not being used for extended
periods of time.
