Functions

3

“ECO” or “I Care” Function:An optimal temperature for food storage can be set which also

gives energy savings.

When this function is selected the appliance will cycle in order to

achieve this reduced energy consumption.

“ICE PARTY” function:

Used, for example, for rapidly chilling a bottle of wine.

To prevent the bottle freezing and breaking, two signals (one

acoustic, one visual) will remind you that a bottle has been

placed in the freezer and that the optimal temperature has been

reached.

Functions

“HOLIDAY” function:

Manages the refrigerator and freezer compartments separately.

The freezer continues to operate normally while the fridge

operates at a temperature of around “+12°C” which means the

fridge door can be kept closed, preventing the formation of

unpleasant odours whilst reducing energy consumption.

4

SUPER COOL Function:

Rapidly chills food placed in the fridge without exposing food

already stored to thermal excursion.

When this function is selected, the refrigerator starts a special

procedure that delivers cooling to the fridge compartment,

lowering the temperature to around “+2°C”.

SUPER FREEZE function:

Freezes food rapidly, enabling longer storage.

There are two options:

24 hours: in this case the symbol remains steadily lit; 48 hours:

in this case the symbol flashes for the first 24 hours and

changes to steadily lit for the last 24 hours.

In the first case, the appliance may end the function on

completion of the 24 hours.

Components

Temperature Probes:The “NTC” Temperature Probes have

the same settings used in the Cooling platform

2005/2008. There are 3:

1. Refrigerator air probe: Which measures

the temperature inside the refrigerator

compartment and relays to the main board

any cooling demand and/or the fact that the

thermostat temperature has been reached.

2. Freezer air probe: Which measures the

temperature inside the freezer compartment

and relays to the main board any cooling

demand and/or the fact that the thermostat

temperature has been reached.

3. Evaporator probe: manages the end of the

defrost cycle by detecting when the set

temperature of +17°C is reached.

IMPORTANT:

The ohm values for checking that the probes are in good working order are the same

used until now since the probes remain unchanged.

24

Temperature Probes:As in Platform 2005/2008, in the event of

malfunction (short circuit or open circuit) of one

or more probes, the appliance will start cycling,

using internal compressor ON/OFF tables

based on the choices made by the user with the

user interface.

IMPORTANT:

The ohm values for checking that the probes are in good working order are the same

used until now since the probes remain unchanged.

Temperatures

(Ohms)

Components

25

Heating elements:Defrosting is performed by the defrost heating

elements. One element covers both sides of the

freezer evaporator with an extension designed to

avoid use of the foam-protected drip tray heating

element used on the previous platform, and a

second element surrounds the foam-protected

air return pipeline.

The evaporator heating element used in three-

drawer appliances and that used in four-drawer

appliances differ in length, nonetheless they

have the same reference value for checking

correct operation (see table below).

Electrical characteristics:• Operating voltage.: 220 - 240 Volts

• Impedance……….: approx. 302.5 Ohm

• At 220 Volts, it has a power rating of: approx. 160 Watts

• At 240 Volts, it has a power rating of: approx. 190 Watts

Components

26

LED indicators:There are 2 connected in series, so

when one LED is damaged, the other

will not switch on and, as a result, both

will need to be replaced. In the event

of malfunction, they must both be

replaced (they cannot be tested

using a multimeter)

Thermal fuse:

Two thermal fuses (one for each

phase of impedance) provide

additional protection during automatic

defrosting.

N.B.: Opens when a temperature of

72°C is reached (Cannot be reset)

Components

27

Freezer Fan (radial type):The radial fan has the capacity to extract

cooled air from the front (green arrow) and to

direct it radially, therefore 90° with respect to

the motor arrangement.

The freezer fan switches on along with the

compressor every time there is a cooling

demand from the fridge or freezer

compartment, circulating warmer air in order to

cool it through contact with the evaporator coil.

It is located at the top of the freezer

compartment and operates at one speed only.

It runs on 12V constant voltage.

The freezer fan starts running as soon as the

compressor switches on.

Components

28

Refrigerator Compartment Multiflow:The fridge multiflow ensures correct air distribution

throughout the fridge compartment by means of

variable diameter vent outlets.

Depending on the height of the fridge

compartment, there are various levels of

cooling:

• height 1750mm: - Electronic 3 levels

- Mechanical 2 levels

• height 1875mm: - Electronic 4 levels

- Mechanical 3 levels

• height 2000mm: - Electronic 5 levels

- Mechanical 4 levels

Freezer Compartment Multiflow:

The freezer multiflow also has the task

of distributing air, in this case

throughout the freezer compartment.

There are different versions of

freezer multiflows:

• 3-drawer electronic appliances:

2 open levels (4 open vents)

• 3-drawer mechanical appliances:

3 open levels (6 open vents)

• 4-drawer electronic and mechanical

appliances: 4 open levels (8 open

vents)

In all cases there are two vents at the

bottom for drawing in air and

channeling it to the evaporator coil.

Components

30

External Air Flow (Fridge Compartment Cooling):Cold air is forced by the radial fan through the smallest

channel (blue arrow) passing through the damper, and is

distributed through the fridge compartment by the multiflow.

Fridge inlet duct

Fridge return duct

Warm air is forced out of the fridge compartment through the longer channel to

the bottom of the freezer compartment, where it comes into contact with the

evaporator coil and is cooled once again.

Components

32

Stepper DamperAlthough the damper is of the stepper type,

it is used like a standard On/Off damper;

fully closed or fully open (90°).

It runs on 12V constant voltage and opens

to let air cooled by the freezer evaporator

pass; this air is then forced back into the

fridge compartment by the freezer cooling

fan each time there is a cooling demand

from the fridge compartment.

Important: The damper is managed

with a single replacement part (KIT)

together with the polystyrene of the

fridge multiflow NOT TO BE

DISMANTLED !!!

The damper opens and closes immediately upon a cooling demand from the fridge

compartment. The only exception is if the ECO (I CARE) function is selected and the

appliance has a Full or Entry board: in this case the damper opens after approx. 35

seconds. Closure, on the other hand, is immediate.

Components

33

Evaporator Cover in PolystyreneThe polystyrene cover is designed to channel /

force air through the evaporator structure in

order to guarantee cooling of air.

It is also very important during defrosting for

insulating warm air in the evaporator area.

It also secures the drip tray in place.

IMPORTANT:1.NEVER pull the polystyrene cover if there is

ice attached AS IT MAY BREAK

2.If the polystyrene cover is removed, always

ensure it is fitted properly back in place

afterwards to guarantee correct appliance

operation

Components

34

Compressor:When the appliance is switched on for the first time, the compressor only starts after

8 minutes.

Between one start-up and the next one there is a minimum safety time of 8 minutes.

Situations in which the compressor remains off even in the presence

of a cooling demand:1. When the electronic protection device is in operation

2. When the electric protection device (Clixon) is activated

3. After the end of defrosting

4. After completion of the "Super Freeze" function

Components

35

Components - VERY IMPORTANT:Electronic Appliances:In these appliances, the damper and the multiflow

polystyrene are managed with a single KIT NOT TO BE

DISMANTLED in order to avoid any leakage of air remaining

after reassembly, which might result in poor appliance

operation.

Electromechanical Appliances:In these appliances, the damper, the multiflow polystyrene,

the damper knob and the plastic cover are managed with a

single KIT NOT TO BE DISMANTLED in order to avoid any

leakage of air remaining after reassembly, which might result in

poor appliance operation.

procedure will finish without signalling any problems.com

Any Last Fault or Non Critical Fault will be shown on the display for the first 20 seconds

after Autotest activation, after which the cycle starts as follows:

Artica FULL & Artica Entry – Critical and Non-critical Faults

42

Critical Faults:These are faults which prevent the appliance from functioning because they

involve a major functional component, for example: Main board, setting file,

solenoid valve.

They are automatically displayed by the appliance:

Critical faults are displayed ONLY IF THE MAIN BOARD DETECTS A

SIMULTANEOUS TEMPERATURE ALARM (“A1” OR “A2”)

Non-critical Faults:These are faults which, even when present, do not compromise the normal

functioning of the appliance, for example: Fridge fan, multiflow heating element.

THEY ARE NOT AUTOMATICALLY DISPLAYED BY THE APPLIANCE since they

do not pose any hazard or risk compromising appliance operation.

They are displayed for 20 seconds when the autotest procedure is activated.

Artica FULL & Artica Entry – Fault & Last Fault Management

43

Fault :• If CRITICAL, it is automatically displayed and the buzzer sounds. To mute the

buzzer, simply open and shut the fridge door. To RESET THE FAULT, switch the

appliance off at the control panel or unplug it from the mains power supply.

• If NON-CRITICAL, it is displayed only for the first 20 seconds when the Autotest

procedure is started. It is only wiped from the memory once the problem has

been solved and the Autotest procedure re-started and completed.

Last Fault:Displayed for the first 20 seconds when the Autotest procedure is started.

To wipe Last Fault from memory, simply complete the current autotest procedure.

Artica FULL & Artica Entry – Fault & Last Fault Management

44

Important notes.

• Critical Faults are displayed only if an alarm condition is also present at the

same time (“A1” or “A2”).

• In a Pre-Fault condition, functions selected using the user interface are not

activated and the alarms “A1” and “A2” are not displayed until the Fault is

confirmed or rejected.

• Faults take precedence over Alarms “A1” and “A2”

• The “A1” or “A2” alarm is displayed only in the absence of a Pre-Fault or Fault.

• During display of a Critical Fault, all function previously chosen by the user are

cancelled and the freezer compartment starts cycling in an attempt to function at

0°C or -12°C, depending on the alarm condition present along with the Fault.
