The refrigerated

equipment should never be installed:

a -near sources of heat such as radiators. direct or indirect sunlight or other equip-

ment which produces heat (photo F);

b -in

line with draughts coming from doors. windows

or ajr conditioning

systems

(photo F).

Do not close or obstruct

the ventilation

openings of the refrigeration

unit. because

this would stop the airflow which cools the refrigeration

unit causing a bad working.

OPERATION

START

After the refrigerated

equipment

has been installed, the power supply voltage has

been checked and the plug has been connected, switch on the unit. When the unit

has reached the working

tempe-

rature, put in the products alrea-

dy cooled.

Do not exceed

the

2/3 of the available

room

with

the product's

level. Leave some

room between the displayed pro-

ducts in order

to allow a good

airflow

and never obstruct

the

air intake situated

on the front

side.

PERIODICAL

MAINTENANCE

We suggest to carry out a tho-

rough cleaning of the cabinet once

a month for the good working,

the good preservation of the food

and the aesthetics preservation of the equipment. The periodical cleaning can be made

by qualified people, who should know the procedures

described

in this paragraph.

ATTENTION!

Before starting any cleaning operation

it is necessary to turn off the

equipment by the on/off red switch and to unplug or disconnect the equipment by the

generai power security switch of your shop. During the whole cleaning operation we

suggest to use working gloves to protect your hand alI the time.

To carry out the cleaning it is necessary:

I -to remove ali goods from the refrigerated unit and to keep them in a freedge or in a

refrigerated ambient suitable for their preservation;

2 -to unplug or disconnect the main on/off switch, disconnect the plug from the power

socket and wait until the equipment temperature reaches the room temperature;

3 -carefully

and thoroughly clean the display surface, the shelves, the glasses with spe-

cific cleaners for any surface. Never use abrasive substances, metal pads or other stuff

which can damage the unit.

4 -after

every cleaning operation it is necessary to rinse with warm water and dry the

unit with a soft cloth; in case the smaller evaporation tray is full, it will have to be emp-

tied and then put again in its originai position.

To clean the condenser unscrew the screws of the front panel.

5 -use a dry paint brush and/or a vacuum cleaner, removing ali dust. Pay attention not

to bend or damage the fins, the tubes or the blades of the fans. Never neglect this ope-

ration, as it is basic for the good working of the unit and to avoid possible breakings.

When the cleaning operation is over, make sure that everything is clean and dry before

connecting the equipment to the power supply again. When the unit reaches the correct

working temperature, it is possible to reload it. In case of long absences (i.e. holidays,

etc.) the unit has to be unplugged, emptied completely, cleaned and dried.

TEMPERATURE

The thermostat.

which

is situated

on the

electrical

control

panel. regulates the tem-

perature

into the equipment

and is usually

preset to +O/+6Co at the factory during the

testing phase.

A lower

performance

must be expected

from the refrigerated

unit when:

-the

equipment

is set on the lowest tem-

perature

-the

equipment

is positioned

in an ambient with higher temperature

or relative

humidity than above indicated

-the amount of displayed products exceeds the maximum recommended and the pro-

per air circulation is prevented.

In those cases the goods are kept at higher temperatures.

the refrigerating

unit has

to run non-stop

and ice may form on the evaporator.

It is necessary therefore

turn the equipment off (approx 24 hours) to allow the melting of the ice.

DEFROSTING

The defrosting takes piace automatically

during the running of the unit. The defro-

sting cycles are 4 a day, last for about 40' each and are controlled

by a timer in the

electrical control

panel. During

the defrosting

phase the temperature

of the unit

could be altered, but when this cycle is over, in a short time the working

tempera-

ture will return to normal. The water from defrost is collected

in a tray equipped

with automatic evaporation

and a smaller tray underneath, which has to be emptied

manually when the automatic

evaporation

is not enough, especially during the sum-

mer months.

TECHNICAL

ASSISTENCE

(servicing)

If the equipment

does not run properly

or does not work at ali, in your own inte.

rest before calling for servicing, we suggest to check the following

points:

-if the plug is well inserted in the socket;

-if the power reachs the socket to which the equipment

is connected;

-if the thermostat

is set as recommended;

-if the network

voltage is the same as requested for the unit (+1- 6%).

DISMANTELLING

OF EQUIPMENT

The demolition

of the unit and the recovery

of the component

materials must be

carried out according to the regulation

in force in this matter. Considering

that the

equipment

is formed

by many different

materials (i.e. ABS with polyurethane

foam

for isolation. glass. stainless steel. aluminium. copper. etc.) and some of them are like

normal urban waste materials while other components.

as refrigeration

gas and oil.

MUST be given to a special recycling center.

REPLACEMENT

OF LAMPS

Disconnect

the main power

supply before fitting

or replacing the lamp. Slip the

ring nuts onto the fluorescent

lamp. Fit the lamp in the lamphoder

and turn it 90°.

Slide the ring nuts along the lamp until they rest on the lampholder

and turn them

clockwise (NPP and NPQ); screw down tightly (NPW).

NIGHT-BLIND

In case that the wall-cabinet

is equiped with a night-blind. we let you note that this

night-blind

is self-blocking. there are no hooks to block it. The night-blind

is equiped

with a spring and must always be pulled on. never left free. during the rolling phase.

The night-blind

can be stopped in any position. according to one.s wish.
