Cleaning And Maintenance; Problem Solving - Hoover HH74DBXP User Instructions

To activate timer, heater must be selected and its power level must
be greater than "0";
Select the zone to be timed. Power level of the zone greater than 0.
Static is displayed in the zone being timed . "0 0" in the digits
reserved for the timer.
1) With "+" or "-" keys, timer time can be chosen. No Beeps at time
change.
2) Pressing simultaneously timer "+/-" keys the timer is cancelled
(goes to 00).
3) If timer "+" or "-" keys is maintained pressed during TBD time, there
is quick setting.
4) When setting timer time, it is possible to go from "00" to "99" with "-"
key, and from "99" to "00" with "+" key.
5) Maximum time 99 minutes.
6) When the time is elapsed and the hob is beeping, press any key and
the alarm and digit sequence will end.
7) It is possible to adjust the timer time while the timer is previously
running.
8) Power of timed zone can be modified without consequences on the
timer programming.
9) Last minute will be displayed by seconds (For Variants only visible if
we enter the timer programming while the last minute of the
countdown)
10) Pressing the Timer key without any selected zone and when no
zone is being timed, does nothing.
11) Pressing the Timer key without any selected zone and when many
zones are being timed, the time shown in time digits changes in a
rotatory way, and shows the time whose power display has the
decimal point ON.
12) Alternatively Power (5s) and (0,5s) is displayed in the zone being
timed.
Remaining time is displayed in the digits reserved for the timer. If
multiple zones are timed, the smallest remaining time is displayed,
and the decimal point is displayed in the corresponding zone.
Residual Heat Indicator (In radiant heaters-> calculated)
The same indicators can be used for "residual heat" indication as well.
A time table must be defined on this purpose: Rest Heat time=f (power
level, working time).
While a temperature on the cook top glass surface is above
o
65 Cb(theory value), this condition will be shown in the associated
display, by means of an "H".
To generate a temperature above 65 C a heating element has to be in
operation for certain time, this time depends on the power level. Once
this time has expired, the residual heat warning will be shown when
the heating element is switched off.
Automatic Safety Off
If the power level is not changed during a preset time, the
corresponding heater turns off automatically.
The maximum time a heater can stay on, depends on the selected
cooking level.

7. CLEANING AND MAINTENANCE

. Before carrying out any maintenance work on the hob, allow it to
cool down.
. Only products, (creams and scrapers) specifically designed for
aglass ceramic surfaces should be used. They are obtainable from
hardware stores.
. Avoid spillages, as anything which falls on to the hob surface will
quickly burn and will make cleaning more difficult.
. It is advisable to keep away from the hob all substances which are
liable to melt, such as plastic items, sugar, or sugar-based products.
.MAINTENANCE:
- Place a few drops of the specialised cleaning product on the hob
surface.
- Rub any stubborn stains with a soft cloth or with slightly damp
kitchen paper.
- Wipe with a soft cloth or dry kitchen paper until the surface is clean.
If there are still some stubborn stains:
- Place a few more drops of specialised cleaning fluid on the surface.
- Scrape with a scraper, holding it at an angle of 30° to the hob, until
the stains disappear.
- Wipe with a soft cloth or dry kitchen paper until the surface is clean.
- Repeat the operation if necessary.
A FEW HINTS:
Frequent cleaning leaves a protective layer which is essential to
prevent scratches and wear. Make sure that the surface is clean
before using the hob again. To remove marks left by water, use a few
drops of white vinegar or lemon juice. Then wipe with absorbent paper
and a few drops of specialised cleaning fluid.
The glass ceramic surface will withstand scraping from flat-bottomed
cooking vessels, however, it is always better to lift them when moving
them from one zone to another.
NB:
Do not use a sponge which is too wet.
Never use a knife or a screwdriver.
A scraper with a razor blade will not damage the surface, as long
as it is kept at an angle of 30°.
Never leave a scraper with a razor blade within the reach of
children.
Never use abrasive products or scouring powders.
. The metal surround : to safely clean the metal surround wash with
soap and water, rinse, then dry with a soft cloth.
Any change in the colour of the glass-ceramic surface does
not affect its operation or the stability of the surface. Such
discolorations are mostly a result of burnt food residues or
use of cookware made of materials such as aluminium or
copper; these stains are difficult to remove.

8. PROBLEM SOLVING

The cooking zones do not simmer or only fry gently
Only use flat-bottomed pans. If light is visible between the pan and the
hob, the zone is not transmitting heat correctly.
The pan bottom should fully cover the diameter of the selected zone.
The cooking is too slow
Unsuitable pans are being used. Only use flatbottomed utensils, that
are heavy and have a diameter at least the same
as the cooking zone.
Small scratches or abrasions on the hob's glass surface
Incorrect cleaning or rough-bottomed pans are used; particles like
grains of sand or salt get between the hob and the bottom of the pan.
Refer to the "CLEANING" section; make sure that pan bottoms are
clean before use and only use smooth bottomed pans. Scratches can
be lessened only the cleaning is done correctly.
