complete breakdown. It is recommended that
the appliance is serviced every 6 months.

 Clean the griddle toaster regularly. A clean

appliance looks better, will last longer and will
perform better. Carbonised grease on the
surface or on the griddle plate will hinder the
transfer of heat from the cooking surface to the
food. This will result in loss of cooking efficiency.

DO NOT use water on the griddle plate while this
item is still hot as warping and cracking may occur.
Allow the griddle plate to cool down before
cleaning.

NOTE:

 DO NOT use abrasive detergents, strong solvents

or caustic detergents as they could corrode or
damage the griddle toaster.

 In order to prevent the forming of rust on the

griddle plate (Steel Plate), ensure that any
detergent or cleaning material has been
completely removed after each cleaning. The
appliance should be switched on briefly to
