For optimum results – read your user’s manual
Before you start using the oven and in order for you to be able to fully utilise its many facilities and
advanced technology, it is important that you are familiar with its operating modes and range of
applications. We therefore recommend that you study the manual thoroughly, because if you do,
you are sure to achieve optimum cooking results through appropriate and safe operation. By going

The oven cabinet and the technical parts of your new HOUNÖ oven are covered by a 12-month
factory warranty. However, the heating elements in the oven compartment and the steam generator
are guaranteed for 24 months. The period of warranty takes effect from the date of installation.
The warranty does not include....
We especially draw your attention to the fact that the factory warranty does not cover glass parts
such as oven door glass, lamp glass and incandescent lamps, nor does it cover sealing such as door
gaskets, gaskets for heating elements, etc.
Furthermore, the factory warranty does not apply in the case of
1. defects that are due to the fact that installation has not been carried out in accordance with the
HOUNÖ Installation & Service Manual at present in force (electricity, water/drain, exhaust).
2. defects and interruptions of operation that are the result of the oven not being handled/operated
as specified in the user's manual.
