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 electrical
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 rectiied by temporary 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
can be hot!
• The unit must not be fully or partially
covered with clothing, or similar
materials, as overheating can result in a
ire risk! (AR300E)
• This appliance is not intended for use
