identifying each case that is manufactured by its model and series.
Check to be sure that the instructions manual corres ponds to the display
case to which it is referring.
If any
information or technical assistance is required, in addition to the
model and machine type, you must also indicate its serial number etc.
3.1.1 DISPLAY CASE NAMEPLATE

HOW TO USE AND PRESERVE THE INSTRUCTIONS MANUAL
This chapter offers some indications on using the i nstruction manual and
on its use limitation.
4.1 INTENDED USER OF THE INSTRUCTIONS MANUAL
This instructions manual is intended for the following personnel.
The purpose of this manual is to indicate how t he machine s hould be us ed
based on its design. It will also indicate its technical features, offering
instructions on how to move, install regulate and use it.
It will also guide you in maintenance work and facilitate spare parts orders.
Fig.1
4.3 LIMITATIONS ON USE OF THE MANUAL
It is important to remember that the instructions manual reflects the
techniques current at the time the machine was purchased, thus, the
manufacturer has the right to update the manual and the equipment without
updating the manual or any prior production, wi th the exception of unus ual
case.
4.4 HOW TO PRESERVE THE MANUAL
We would like to remind the user that the manual must be pres erved with
care to ensure it will last as lon g as the machine. Therefore, it is supplie d in
a special case that can protect it from wear and tear over years.
In addition, two copies of the section c onc erni ng “display case handing” are
furnished so that the shipper and th e personnel responsible for unloading
the machine can consult this section without referring to the main text.
If the manual gets lost or destroyed, a c opy can be requested through the
firm’s area representative or directly from the manufacturer. Be sure to
specify the type, serial number and year the display case was
manufactured.

HANDLING AND INSTALLING THE DISPLAY CASE
5.1 RECEIVING THE DISPLAY CASE
The display case has packaging around it to protect it during shipment a nd/or
storage, the body and the glass are packed separately.
Comprised of:
A wooden pallet
Two wooden boxes
Figure 2 show the standard packing.
There is a table (Fig.3) on the packing and its purpose is to give detailed
product information.
IMPORTANT: Remember that since cardboard packing is used, it is
subject to the action of atmospheric (rain, snow).
Therefore, the display cases must be stored in a dry indoor area.
eed as follows for the unloading, transport and unpacking operations.

Temporary or extended storage must be
done in indoor areas protected from
atmospheric agents.
Th
e display cases must be handled with
care.

5.2 UNLOADING OPERATIONS
The orientation of the packed display cas e mus t c omply with the indications
listed on the pictograms and the writing on the outside package.
Conduct the unloading operations using su itable hoisting equ ipment
(the capacity must be adequate for the we ight of the packed display case),
hoisting it as shown in Fig4.
5.3 CHECKING THE SUPPLY
Before taking delivery from the shipper, check the conditions of the
packi g. If it shows obvious damage on t he outside, the display case co uld
n
be damaged. In this case, unpack the display case in the shipper’s
presence. Any damage caused by i ncorrec t han dling and stora ge is not the
manufacturer’s responsibility.

A) Contact your area representative.
B) Draw up
C) Send a copy of the report to The manufacturer or area representative
a written report
5.4 UNPACKING
All the unpacked materials can be recycled in order to dispose of
according local legislation. Be sure to destroy plastic components to
prevent any hazards (suffocation) to children.
5.5 PERSONNEL REQUIREMENTS
We recommend that the operations to m ove the display case be handled
by personnel accustomed to using hoisting equipment, in full compliance
with the safety standards in force.
5.6 HANDING THE DISPLAY CASE
The display case can be lifted with a fork-lift truc k or with any other suit abl e
means with a minimum capacity of twice the weight of the display case
(see the specific nameplate). Operators running the hoisting equipment
must remain at an adequate distance from the hoisted part and must
ensure that no people or property is exposed t o danger if the display ca se
should drop. Movements must be slow and continu ous to prevent the case
from tipping over, etc.
The chapter offers various general information on the purposes of the
display case, describing its main functions and use limitations.
Damages caused by handling errors are not covered

TECHNICAL DESCRIPTION OF THE DISPLAY CASE
7.1 GENERAL INFORMATION
This chapter offers a technical description of the display case and its
operation. It supplies all the inf orma tion deemed useful for the operator an d
maintenance personnel so they can gai n a better understanding of correc t
operation to enable more rapid identification of any fault or malfunctions.
Display section
The display section is the area in the display case that holds
the bubs of food. The model and name for the display case is
different, but their function is same.
Glass stru
The glass structure is composed of two glass side panels
and a front window that makes it possible to
--guar
--protect the contents of the display section from foreign
matter
All the glass can be dismounted simply by removing the
screws and the connection bar. We recommend performing
these operations with the maximum care, observing the
indication listed in the maintenance chapter.
.
Motor compartment
The motor compartment is located in the lower section of the
showcase and all the components required for machine
operation are positioned together in a unit referred to the
condenser unit.
--The main components of the condenser unit are:
--Compressor
--Condenser
--Fan
--Condensation evaporation tub
--Solenoid valve
--Filter
--Other refrigeration components
The muter compartment is protected by a iron bracket.
Compressor split and rear grate that are bolted on to ensure
maximum safety. In particular during normal operation no one
is able to access it an come into contact with live or moving
elements .Only qualified technicians are allowed to access it.

Control panel
The control panel is the element th at manages the operation of the display
case.
This management (temperature control and maintenance, defrosting) is
entrusted to a command switchboa rd. In any event, the operator can utilize
this component to change the temperature inside the display section.
Verify that when the display case is installed, the general switch is it.
When the main switch is on, this guarante es the operation of the oil-heating
resistor inside the compressor (this is independent of the start-up of the
display case).
