together, the timer is cancelled and ”--“ will show in the minute
display.

13
When the cooking time is reached, the corresponding cooking
zone will switch off automatically and the beeper will sound a
single beep.

14
Efficient Use of Your Hob
Before using your hob for the first time, switch the zones on for a
FEW SECONDS to burn off any grease left over from the
manufacturing process.
The ceramic glass retains heat, so to make best use of the
residual heat, switch off the zone five minutes prior to the end of
cooking.
To reduce the cooking time, the zone can be set to the maximum
setting at the beginning of cooking, and then reduced during
cooking time.
The hob is equipped with zones of different sizes, designed to
accommodate most shapes and sizes of pan. For best results,
only use pans with flat bottoms and choose an appropriate zone
depending on the size of the pan. The most efficient use of the
hob is shown below, where the pan and zone are correctly
chosen.
Use pan lids where possible to minimise the energy usage of your
appliance.
Zone Size Minimum Pan Size (mm) Maximum Pan Size (mm)
165mm 145 185
200mm 180 220
It is very important that the pans used on the hob are made of a

15
suitable material and have the correct type of base. The base
should be flat and smooth, as any rough part on the pan base
could scratch the ceramic hob top.
Choose pans which are between the sizes recommended in the
table above, and with bases that are as non-reflective as possible,
e.g. dull and dark.
Only pans recommended for use on ceramic hobs should be
used.

16
Care and Maintenance
Always disconnect the appliance from the power supply before
undertaking any cleaning or maintenance. You should use a non-
abrasive cleaner to clean the hob top. Any abrasive cleaner
(including Cif) will scratch the surface and could erase the control
panel markings.
