Pyrolytic Oven - Default 420°C - SK520 only
NOTE: This function has an added safety feature to
prevent it from being selected accidentally. To run the
pyrolytic function, select “Pyrolytic” on the “Function
Selector Display”, then press the sensor. The door
will lock and remain locked until the appliance is cool.
This oven can clean itself by a process known as pyrolysis, heating the
cavity to a temperature of approximately 420˚C. This will burn o the
residue from spattering and spillages caused by cooking.
Pyrolytic programmes should be used when the oven smokes during
preheating or cooking or if the oven smells even when cold. It is not
necessary to run a pyrolytic programme after every use of the oven.
Do not wait until the oven is coated in grease to run a pyrolytic
programme.
The smoke produced by pyrolysis is broken down by passing through a
catalyser.
After a pyrolytic function has been completed, disconnect the appliance
from the power supply and wipe clean the interior of the oven with a
damp, clean cloth. Allow the interior to dry before reconnecting the
power to the appliance.
Eco Fan Oven - Default 180°C
With this function, the appliance is saving energy. This
produces similar results to normal fan oven but saves
energy.

14
Before any pyrolytic programme, remove all shelves, trays and
other accessories from the oven and clean up any major spills to
avoid the risk of fire or excessive smoke.
During the pyrolytic process the oven exterior including the door
will become hotter than during normal cooking. Children and pets
must be kept away from the oven. Do not hang towels or cloths on
the oven handle at any time.

Cleaning and maintenance
Keeping your oven clean and well maintained helps to prolong the
fault-free lifespan of it and helps prevent your home from being
filled with odours. It is important that, before any cleaning or
maintenance is performed, you switch o the oven at the mains
supply. Do not start any cleaning or maintenance until the oven
has been allowed to cool completely.
We recommend always wearing PPE (Personal Protective
Equipment) when carrying out any cleaning or maintenance.
Cleaning the oven exterior
As the oven has, glass, stainless steel and enamel surfaces you
should use a nonabrasive cleaner. Any abrasive cleaner (including Cif)
will scratch the surfaces and could erase the control panel markings.
Stainless steel can be eectively cleaned by simply using a dilute
solution of water and mild detergent and drying to a shine with a clean
cloth.
Proprietary stainless steel cleaners are available. We recommend
a microfibre cloth for stainless steel surfaces. If necessary, wipe
any area that has been cleaned using a damp soft cloth or tissue to
remove any residual cleaning fluid and then wipe dry with a clean, dry
cloth or tissue (such as kitchen towel).
Cleaning the oven interior
The oven should always be cleaned after use when it has been
allowed to cool down.
The cavity should be cleaned using a mild detergent solution and
