SETTING THE TEMPERATURE
OF THE REFRIGERATOR AREA
The refrigerator display indicates
the actual internal temperature of
the refrigerator compartment ranging
from 0°C to 19°C; if the temperature
exceeds 19°C, the symbol «H»
appears on the display. Refrigerator
temperature can be adjusted by

will be stored after the display has
stopped fl ashing (6 seconds)
CHECKING THE PROGRAMMED
TEMPERATURE
If the symbol (refrigerator
area) and the symbol (freezer
area) are touched once, the
programmed temperature will fl ash
on the display for 6 seconds; after,
the actual temperature inside the
compartments will be displayed.
The set functions remain stored in
the memory of the appliance, even
in the event of a power cut or when
the appliance is disconnected from
the electricity supply; upon startup,
the last temperature setting for both
compartments will fl ash on the display.
HOLIDAY FUNCTION
The “HOLIDAY” function may be
used during periods of prolonged
inactivity (for example, if all users go on
holiday). This function saves electricity
as it takes into account the fact that
the door of the appliance will not be
opened at all during this period and
maintains a temperature inside the
refrigerator which is suitable for the
storage of food.To activate this function,
simply touch the text “HOLIDAY” for at
least 0.5 seconds; the text will be lit
up in white. The function may only be
deactivated manually, by touching the
text “HOLIDAY” for 0.5 seconds. While
the appliance is operating in “HOLIDAY”
mode, all other settings are temporarily
disabled.
SUPERFUNCTION
The Super function was designed
to reduce the temperature inside
the refrigerator compartment in the
shortest possible time; if you touch
the text “SUPER” for at least 0.5
seconds the function will be activated
for a period of 7 hours, during which
time the text “SUPER” will be lit up
in white. After this 7-hour period, the
Super function will be deactivated
automatically. However, if you wish
to manually deactivate the function
before the 7-hour period has elapsed,
simply touch the text “SUPER” for at

11
ENGLISH TECHNICAL PASSPORT
Refrigerator NRS 1857
least 0.5 seconds; when the function
has been deactivated the text “SUPER”
will no longer be illuminated.
While the appliance is operating
in Super mode, all other freezer
compartment settings are temporarily
disabled.
PRE-ALARM MODE
AND FREEZER TEMPERATURE
The pre-alarm mode is activated
when the temperature inside the freezer
compartment reaches a value higher
than -12°C (for example, -11°C). This
may occur in the following situations:
 a large amount of unfrozen
food has been placed in the freezer (see
freezing modes);
 the door has been open for an
extended period of time;
 the electricity supply has been
cut off for a prolonged period of time;
 the appliance has
malfunctioned.
The pre-alarm mode is indicated
by the temperature appearing
intermittently on the freezer display, by
the fl ashing white ALARM symbol and
by the audible alarm.
The audible alarm may be disabled
by touching the ALARM text;
in this case the pre-alarm mode
indicator of the fl ashing temperature
on the display remains active and the
ALARM text will remain lit in a fi xed
manner instead of fl ashing. The prealarm
mode is disabled automatically, but only
when the temperature of the freezer
compartment falls below -12°C; at this
point the ALARM text will no longer be
illuminated, while the temperature will
stop fl ashing and remain lit in a fi xed
manner on the display
FREEZER TEMPERATURE ALARM
The alarm function was designed
with the aim of warning the user
that, due to some external cause (for
example, a power cut, the door has
been left open, etc.) the food kept in
the freezer compartment has reached a
temperature higher than +1°C and has
therefore completely thawed out.
In this case, the freezer temperature
alarm mode is enabled and fl ashes
on the display, along with the highest
temperature detected inside the
compartment; the ALARM text is
illuminated in red and the audible
alarm is also activated.
The display memory (maximum
temperature reached) is important
because, if power is cut off and then
restored, the appliance will continue
operating as normal; this could result in
food which had previously thawed out
being refrozen.
DOOR OPEN ALARM
Every time the door is opened the
symbol (refrigerator) and/or the
symbol (freezer) lights up in white, in a
fi xed manner; if the door remains open
for over 2 minutes, the “Door Open”
buzzer alarm sounds; it may be deacti-
vated in one of the 2 following ways:

12
TECHNICAL PASSPORT ENGLISH
Refrigerator NRS 1857
by closing the door, both the
buzzer and the visible alarm signal
deactivate;
 if the symbol (for the
refrigerator door) or the symbol (for
the freezer door) is touched, only the
buzzer deactivates, while the white-lit
visible alarm signal starts fl ashing.
INTERNAL LIGHT
Every time the door is opened,
the light inside the refrigerator
compartment is switched on; if the
door is opened for an extended
period of time, the light switches off
automatically after 5 minutes. To switch
it back on, simply close the door and
open it again.
MALFUNCTION MANAGEMENT
If the symbols «E»,»E-»,»-E», appear
on the refrigerator-freezer display, the
appliance is guaranteed to function
for a few days, but the Technical
Assistance Centre should be contacted
immediately.
6.2. BASIC SETTINGS
POWER CUT
If a power cut should occur, try to
establish its duration.
If the forecast is less than 12 hours,
leave the food in the freezer and keep
the door closed.
If the power cut lasts for longer than
12 hours and part of the food starts to
thaw out, this should be consumed as
soon as possible.
 Remove the food, wrap it in
several layers of newspaper and place
it in the fridge or in a cool location.
 Remember that an increase in
the temperature of the food will greatly
reduceits storage life.
WARNING!
Do not use any mechanical devices or
other artifi cial methods other that those
recommended by the manufacturer for
accelerating the defrosting process.
WARNING!
Unless otherwise approved by the
manufacturer, do not use electrical
appliances inside the food storage
compartment.

USING THE FREEZER
COMPARTMENT
When you purchase frozen food
always bear in mind the following
factors:
 The packaging or packet must
be intact, otherwise the food may spoil.
 If a packet is swollen or shows
damp marks, it has not been stored in
optimum conditions and may have start-
ed to thaw.
 Purchase frozen food goods last
and transport them in an insulated box.
 As soon as you arrive home,
place the frozen goods immediately in
the freezer compartment.
 Avoid or reduce variations in
temperature to a minimum.
 Keep to the expiry date shown
on the frozen food package.
 Always follow the instructions
on the packaging on how to preserve
the frozen foods.
 The maximum amount of
fresh food that can be frozen is shown
in kg/24h on the rating plate with the
technical specifi cations.
 Avoid placing food that has
to be frozen in contact with food
that has already been frozen so that
the latter does not under go a rise in
temperature.
Production of ice cubes
 Fill the ice container three
quarters full with water; place it on the

sume it within 24 hours.
7. MAINTENANCE
AND CLEANINGS

14
TECHNICAL PASSPORT ENGLISH
Refrigerator NRS 1857
NOTE:
 The distance between the
shelves and the rear internal wall of the
refrigerator ensures that air circulates
freely.
 Do not place food in direct con-
tact with the rear wall of the refrigera-
tor compartment.
 Do not place food that is still
warm into the compartments.
 Keep all liquids in closed con-
tainers.
 The NO-FROST system guaran-
tees a constant emperature and a more
rapid freezing capacity.
The humidity-free, forced air circula-
tion tends to dry food up quickly and for
this reason we advise keeping all food
in closed containers.
7.1. RECOMMENDATIONS
When cleaning the internal plastic
parts and the door gasket:
Do not use abrasives or detergents
af any kind, when cleaning the internal
