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 and is 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
driven out of 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.
Safety
• Keep the areas around the air intake
and exhaust grilles free from possible
obstructions!
• During operation the surfaces of the unit
are hot!
• The unit must not be fully or partially
covered with clothing, or similar
materials, as overheating can result in a
fire risk! (AR300E)
• This appliance is not intended for use by
persons (including children) with reduced
physical, sensory or mental capabilities,
or lack of experience and knowledge,
unless they have been given supervision
or instruction concerning use of the
appliance by a person responsible for
their safety. Children should be supervised
to ensure that they do not play with the
appliance.
