Before carrying out any operation on the equipment, the User and the Qualified Technicians must carefully read  the instructions, call the Retailer for clarification.

1.2 WHO THE MANUAL IS FOR?

The manual is aimed at the both Retailers and users and also to maintenance workers qualified to carry out work  on the equipment.

The user must not carry out work reserved for qualified Maintenance workers and/or technicians.  The Manufacturer is not responsible for any damage caused by lack of respect for this last regulation.

1.3 SAFEKEEPING

The Manual for Use and Maintenance must be kept in the immediate vicinity of the equipment, in an appropriate  holder and, above all, protected from liquids and other substances that could make it illegible.

1.4 SYMBOLS USED

2. DESCRIPTION AND OPERATION OF THE APPLIANCE

2.1 DESCRIPTION

The upright refrigerators are condensed air refrigerator units made up of:

• A condensing unit (outside cold storage room) 
• A evaporating unit (inside cold storage room) 
• A control panel (positioned on the condensing unit) 
• Defrosting is of the electric type and it is automatic 
• Condensation is air based 

2.2 OPERATION

The upright refrigerators are refrigerator units which function by means of refrigerator compressor of the  airtight type. With air tight motion and alternative motion, powered by electricity (mono phase or three phase)  and using as a refrigerant the fluid R404A/R134A.

Principle of refrigerator operation cycle

In thermodynamics for the refrigerator cycle we intend the change of state which a certain body undergoes (for  example a refrigerating fluid). The passage of the refrigerating fluid from the liquid state to the gaseous state takes place in the evaporator. Because this is an endothermic phenomenon, it needs heat which, when it  happens, is taken from the air which the evaporator comes into contact with. So, when coming out of the  evaporator, the vapours of the refrigerating fluid are sucked out by an air compressor and sent to the condenser.  If the latter takes away not only the heat that the gaseous refrigerating fluid has acquired during the course of  the evaporation (ENTALPIA DI EVAPARATION), but also the calorific equivalent of the compression work, then  the fluid returns to the liquid sate. Because liquefaction is an exothermic phenomenon, there is production of  heat, which is disposed of through air and through water. The refrigerant fluid, leaving the condenser, passes  through an expansion organ and returns to the evaporator, thus completing the cycle.

3. PREARRANGEMENTS

3.1 ILLUMINATION

The illumination of the area must conform to the POWER regulations of the country in which the equipment is  installed and must, in any case, guarantee good visibility at all points, it must not create dangerous reflections  and must allow for easy reading of the controls.

3.2 VIBRATIONS

In conditions of use which comply with the indications for correct use, the vibrations are not enough to create  dangerous situations.

In the case of long periods of inactivity, the upright and/or table refrigerators must be stored with attention to  relevant storage place and time:

• Store the upright and/or table refrigerator in an enclosed area; 
• Protect upright and/or table refrigerator from bumps or stress; 
• Protect upright and/or table refrigerator from high thermal variation; 
• Avoid upright and/or table refrigerator coming into contact with corrosive substances. 

5.3 CHECKS

Before putting upright and/or table refrigerator into operation, it is necessary to carry out a series of checks to  prevent errors or accidents during the activating phase:

• Checks that there has not been any damage to the upright and/or table refrigerator during assembly.
•  Check with care the integrity of the control panel, the electric cable and the tubes.
• Check the precise connection to external energy supply. 
• Check the free movement and rotation of any moving parts.

6. INSTALLATION

For an optimum functioning of the unit it is advisable to place the refrigerator in a zone with a good exchange of air and far away from any sources of heat.

6.1 SETUP

• Carefully remove the packaging from the refrigerator; 
• Remove the white PVC protection film from the stainless steel and all the protection used by the  company to reduce the risk of damage during transport; 
• Place the refrigerator on a flat level surface (use the adjustable feet)(Fig. 1) 

Before use, clean the refrigerator with a clean, soft cloth or using a spray product. It is best use little water as it  contains minerals which leave traces which are difficult to remove quickly;

• Wash the tray and all the internal parts using anti-bacterial detergents to be found commercially;
•  Remove the detergent with a soft sponge soaked in water and dry with a clean soft cloth; 

Do not use abrasive detergents or powders which could make the finish opaque. During these phases do not, as  already stated, use great quantities of water which could damage electric parts;

a damp sponge is sufficient.

• Place the self-support inside the refrigerator, in the most suitable position for use, inserting each  support in to the holes on the base of the refrigerator and inserting the side tab in the appropriate  place on the sides or on the table supports. (Fig. 2) 
• Slide the shelf into the supports as shown in. (Fig. 2) 
• Slide into the appropriate runners, on the lower part of the refrigerator, the condensation waste tray  and for appliances which have automatic trays, connect the connector. (Fig. 3) 

6.2 PREARRANGEMENTS

• Check that the cables and the sockets are suitable for the power absorbed by the equipment. THE USE OF ADAPTORS, MULTIPLE SOCKETS AND/OR EXTENSION LEADS IS FORBIDDEN.
• Ensure that the upright and/or table refrigerator is not installed near to sources of heat like: ovens,  radiators, direct sunlight etc. 
• Leave a space of at least 75 mm (3 inches) between the back of the upright and/or table refrigerator  and any wall, to avoid the formation of condensation. 
• The motor must be free of any obstacle which could hinder or limit the circulation trough the  condensing unit situated on the top side part of the refrigerator. 
• The distance between the refrigerator and the ceiling must be less 50 cm. (19 ¾ inches).
•  Check that the environment has a sufficient change of air, in order to guarantee the cooling of the  condenser and the compressor unit. 
• For a perfect functioning of the equipment, the maximum temperature of the environment should not  exceed +43°C (109 °F), except for static models which should not exceed +32°C (+95°F). 

Lack of respect for these conditions will provoke a serious decline in the functioning of the equipment, early  ageing of the compressor and a much higher consumption of energy than normal.
