  • Page 5: Installation

    INSTALLATION • Recommend to place the refrigerator out of the reach of direct sunlight or electric home appliances causing heat, such as a stove or a dishwasher. In hot conditions or environments, the refrigerator will work less efficiently. • Connect it to a plug with the voltage indicated in the series plate placed in the back of the refrigerator. Don’t install other machines in this same plug in order to avoid voltage fluctuations.
  • Page 6 Refrigerator Care and Cleaning It is important to preserve food at a low temperature to maintain it for a long period, which can be obtained through the following practices: 1. Recommend not opening the refrigerator doors unnecessarily. 2. Recommend not putting hot food and / or hot containers into the refrigerator. 3.

  • Page 7: Door Adjustment

    Door adjustment Adjust the door with the key included in the refrigerator until the magnetic gasket touches the cabinet uniformly and the door is lined up with the cabinet edges. See figure 1. FIGURE 1 Door gasket replacement 1. Dismount the refrigerator’s door. 2.

  • Page 8: Section B Electric Components

    SECTION B – ELECTRIC COMPONENTS LINE VOLTAGE It is essential to know the line voltage in the refrigerator. A voltage reading should be taken at the compressor start and during its operation. The line voltage should not fluctuate more or less than 10% with respect to the nominal. A low voltage overheats the compressor motor windings resulting into the compressor cycling for thermal overload or impeding the compressor starting.
  • Page 9 Before a pre – defined condition, the main winding current, which is also the current passing through the relay coil is reduced to a value under the required value in order to maintain the relay armature lifted. The armature turns down, opens the start winding contacts and removes the start winding of the circuit.

  • Page 10: High Efficiency Compressor, Electric Components And Circuits

    HIGH EFFICIENCY COMPRESSOR, ELECTRIC COMPONENTS AND CIRCUITS The high efficiency compressors of the new series are equipped with totally new electric components consisting in a PTC relay , a thermally operated overload protector and a run capacitor. Solid State Relay - See figures B3 and B4 The solid-state relay has no mobile parts.
  • Page 11 How to verify the overload protector: 1. Disconnect the refrigerator’s feed electric cable. 2. Remove the relay cap, and take away the compressor relay. Disconnect one protector wire and remove it from the compressor. 3. With an ohmmeter, measure resistance between the pawl terminal and the female plug terminal. At normal room temperature, the overload protector resistance must be lower than 1 ohm.
  • Page 12 Run capacitor Overload Start Motor comp. PTC relay Figure B5 – Compressor start circuit Compressor start circuit - See figure B6 When the auto - heatable state relay reaches enough temperature, it changes abruptly from a low resistance (3-12 ohms) to a high resistance (10 - 20.000 ohms) and actually “switches off” the start windings. The relay does not shunt the run capacitor any more.

  • Page 13: Compressor Motor Electric Checking

    COMPRESSOR MOTOR ELECTRIC CHECKING When checking electric problems, always make sure there is an electric circuit to the cabinet, and the temperature- selecting dial is not in the “OFF” position (switched off). When the shielded unit doesn’t start, the problem can be found in the relay, the protector, the thermostat, the wire or the compressor motor itself.
  • Page 14 As the temperature control is adjusted from COLD to VERY COLD, the temperature differences found between the compressors stop and start increases. This situation occurs when the thermostat finds a temperature of 4.5±1.0°C, as a result of the plate heating by the defrosting resistance. This model allows controlling the plate defrosting resistance when the compressor stops during the cycle and also disconnects all the electric systems (except lighting), when it changes to the switched off position (0).

  • Page 15: Thermostat Replacement

    THERMOSTAT REPLACEMENT Semi – automatic / manual defrosting models (Figure B7-A) Disconnect the electric current unit. 1. Take away all food in the compartment and defrost completely. 2. Unscrew the evaporator (of the roof or the frame, accordingly) 3. Remove the evaporator thermostat bulb. 4.
  • Page 16 Frost free with plate - Conventionals (Figure B8-A) The motor is located on the fins evaporator to suck the air through it, and is projected by the fan cover grills moving the air only in the freezer and returning it by the evaporator cover inferior slot to complete the airflow. In this case the fridge flow is obtained by means of natural convection when passing through the plate.

  • Page 27: Refrigerant Cycle

    REFRIGERANT CYCLE The refrigerant cycle is continuous and takes place every time the compressor functions. When the refrigerant passes through the evaporator it changes state (from liquid to gaseous), due to the heat entering the cabinet through its isolated walls and the heat because of stored products and the times the door is opened. Then, vapor is extracted from the evaporator through the suction line and taken to the compressor.
