4.2 Frost protection
Turn the temperature selector as far to the right as possible.
In this position, the temperature controller switches on the
heating element automatically if the room temperature drops
below the frost protection temperature.
4.3 Limiting the temperature controller
Using the two pins fitted to the back of the control casing, you
can fix the temperature controller at a certain setting or limit the
temperature setting range.
Break out the pins.
To fix the selected temperature, push a pin into the hole op-
posite (see diagram).

5. Cleaning, care and maintenance
CAUTION Burns
Never spray cleaning spray into the air slot.
Ensure that no moisture can enter the appliance.
If a pale brownish discolouration appears on the appliance
casing, wipe it off with a damp cloth.
Clean the appliance when cold with ordinary cleaning products.
Avoid abrasive or corrosive cleaning products.
Note
As part of regular maintenance, we recommend also
having the control components checked. The safety and
control components should be checked by a contractor
no more than ten years after commissioning.
6. What to do if...
... the appliance does not heat up:
Check the temperature set at the appliance and the MCB/fuse
in your fuse box.
The appliance has a safety temperature controller that shuts the
appliance down if it overheats. After the cause has been removed
(for example air outlet or inlet apertures covered) and the appli-
ance has cooled down for a few minutes, operation starts again.
If you cannot remedy the fault, contact your contractor. To facilitate
and speed up your enquiry, please provide the number on the type
plate (no. XXXXXX - XXXX - XXXXXX).
