COMPONENT FUNCTIONS General Information The power module is made up of a number of smaller individual modules (sections), each one controlling a functional component. The modules are linked together when required to control a particular function or functions. The linking of the individual modules is optional and therefore allows for each module to be switched ON or OFF, this is determined from the data stored or collected by the modules and the results of module comparisons. The power module memory stores information such as temperatures and times. Having individual set of parameter values built in to it, directly aimed at providing the specific control needs for the physical and system characteristics of the model type. Fridge & Freezer Control The power module monitors the fridge and freezer air sensors, comparing their sensor resistance values with the cut-in and cut-out parameter values stored in its memory. Although the parameters are set, they allow for adjustment within those parameters so that the user has control. The results from the comparisons will determine if cooling is initiated, other circuits of the module will also use the results. The power module will enable normal operation provided there is no malfunction condition. Fridge or Freezer Malfunction Module The fridge or freezer malfunction module enables the appliance to continue operating in the unlikely hood of the fridge or freezer sensors failing. Pre-set timed functions stored in the modules memory is used to cycle cold request on and off. A malfunction occurs when the fridge or freezer cabinet sensors return a value to the module of either Open or Closed circuit, rather than a particular resistance value. Evaporator Fan Module The freezer fan is located above the evaporator coil and is designed to distribute the cold air produced by the evaporator coil uniformly inside the freezer compartment and when necessary in the fridge compartment. The freezer fan is managed by the module and is switched on/off after a preset time interval that is parameterised in the modules memory after a compressor start/stop. The fan will not operate when in the defrost cycle. After the defrost cycle the fan starts after a timed interval following a compressor start, this interval is also parameterised in the modules memory; this interval is different from the interval programmed for normal operating conditions. Electronic Motorised Damper Assembly (Baffle) The purpose of the damper is to allow the cold air produced by the evaporator to be distributed inside the refrigerator compartment. The damper is located in the top left hand (SX) corner of the fridge compartment. It is controlled by a fridge air sensor (thermistor) positioned in the centre of the rear wall of the fridge. Cold air from the evaporator is distributed in the refrigerator compartment. continued... 12 of 37
COMPONENT FUNCTIONS Compressor The compressor is managed by the power module and switches on whenever a demand for cooling is received. There are situations of cooling demand in which the compressor remains off. These are as follows: 1. Compressor protection: the compressor switches on once a minimum safety time lag has elapsed since the last power-off, thereby allowing the refrigerant gas pressure to reach a point of equilibrium in the refrigerant circuit. The same minimum safety time is observed in the event of a mains power interruption (voluntary or involuntary). This compressor protection strategy is observed only after the product has been operating continuously for the number of hours defined in the module memory. 2. Pause after defrost: at the end of the defrost cycle the compressor observes a protection time parameterised in the module memory so that the water formed during the defrost can be completely drained. 13 of 37

AIR FLOW COMPRESSOR AND CONDENSER COMPARTMENT The condenser fan is mounted at the rear near the compressor and draws air from the room through the right side of the front lower grille (A), through the condenser (B), around the compressor (C) where it exits out of the rear panel (D) but mainly passes over the dissipator to evaporate the defrost water (E) and finally exits out through the left side of the front lower grille. See image below: D C B E A THE ABOVE PROCESS IS REPEATED SO LONG AS THE CONDENSER FAN IS RUNNING. 18 of 37
AIR FLOW FRIDGE AND FREEZER INTERIOR COMPARTMENTS FREEZER The freezer evaporator is mounted just above the evaporator assembly (F). The fan draws air up through the evaporator where it is cooled (G) and blows into the top duct panel where it is channelled out through outlet ports (H). The air circulates around the freezer and returns through lower grille (J) and is drawn back up through the evaporator where the process is repeated. FRIDGE When there is a demand for cooling in the fridge, the damper (baffle) opens allowing cooled air from the freezer to enter via a ducting in the top left of the fridge (K). The air circulates around the fridge and returns to the freezer through the lower ducting (L). This process is repeated so long as the fridge damper is in the open position. MEAT / VEGETABLE DRAWER TEMPERATURE CONTROL SLIDER The cold air is conveyed inside the meat drawer through an adjustable opening between the fridge compartment and the freezer compartment. In this way the temperature inside the meat drawer is kept lower than the rest of the fridge. H K F G J L 19 of 37
THE SANKYO ICEMAKER HOW THE ICEMAKER WORKS Water is automatically measured into the icemaker mould by the inlet solenoid water valve. The Bi-metal thermostat mounted between the support housing and the mould detects the water / ice temperature. When the ice is cooled down to about - 9 C the thermostat switches the icemaker motor and the icemaker heater ON. The motor and the ejector blades begin to rotate. Because the ice is frozen hard in the mould the motor will stall the ejector blades as they apply pressure on the ice. During the stall period the heater warms the mould to loosen the ice. This may take a few (up to five) minutes. When the ice is loose enough, the ejector blades and the motor will complete the rotation and eject the ice from the mould. The ice collects in the ice bucket below the icemaker. The water inlet valve solenoid switches on again, to fill the mould with fresh water. NOTE: The Icemaker can only be checked with the 'Built-In Auto Test routine', see page 16. 20 of 37
POWER MODULE Parameters Parameter Values Stored in the Module Memory Direct the Appliance Operations - Parameters set in the module memory control the appliance functions. The minimum and maximum values for temperature are preset in the module memory. Sensors monitor temperature and the values are registered in the module. Where the sensor values are outside the presets a particular function will start or stop. Where a sensor fails, open or closed, the appliance operation will be controlled by time. The timed values for this are calculated in the module memory. The power module monitors door opening times and compressor run times. When the total of the door open and compressor run times are equal to or exceed the parameter values set in the memory, a defrost sequence will be initiated. COMPRESSOR OPERATION Compressor Operation - There are situations of cooling demand in which the compressor remains off. These are as follows: Compressor protection: the compressor switches on once a minimum safety time lag has elapsed since the last power-off, thereby allowing refrigerant gas pressure to reach a point of equilibrium in the refrigerant circuit. The same minimum safety time is observed in the event of a mains power interruption (voluntary or involuntary). Approximately 7 minutes Pause after defrost: at the end of the defrost cycle the compressor observes a protection time parameterised in the module memory so that the water formed during defrost can be completely drained. Approximately 7 minutes 21 of 37
POWER MODULE Parameters DEFROST HEATING ELEMENTS Defrost Heating Elements - The parameters utilised to start the defrost cycle are as follows: Compressor ON time since the last defrost cycle. 8 hours, but the start time will reduce dependant on door opening times. The appliance is plugged in and switched on. Total time since the last defrost cycle. 50 hours, but the start time will reduce dependant on door opening times. The parameters utilised to end the defrost cycle are as follows: Maximum time defrost heater is ON. Approximately 20 minutes Defrost end temperature (freezer defrost cut-out). +7 C ± 3 C FREEZER FAN OPERATION Freezer Fan Operation - The freezer fan is managed by the power module and is switched on/off after a preset time interval that is parameterised in the memory after a compressor start/stop. After the defrost cycle the fan starts after a timed interval following a compressor start, also this interval is parameterised in the memory; Compressor 7 minutes PLUS 3 minutes for the Fan = 10 minutes 22 of 37

INSTALLATION INSTRUCTIONS INTRODUCTION The model you are installing may differ slightly with respect to some descriptions in this installation, since this covers several models. Install the appliance in a dry and well-ventilated place. Avoid locations in direct sunlight or near a source of heat (oven, heating, etc.). If this cannot be avoided, install the appliance respecting the following minimum distances: Coal or paraffin stoves: 300 mm Electric and/or gas stoves: 30 mm To allow product handling and sufficient air circulation, leave at least 10 mm clearance at the sides, above the appliance, and between the rear panel and the wall. WATER CONNECTION Disconnect the appliance from the mains power supply before starting operations. The icemaker and water circuit must be connected to a water supply of potable and/or chemically purified water. The water connection must be carried out in compliance with local regulations. The appliance is supplied with a water tube, already attached to the back of the product. Remove the shipping tape from the coiled water tubing on the rear of the appliance. Connect the transition connector (1) to the household water supply (2). Make sure that the water tube is not twisted. The appliance is pre-set for operation at pressures between 1.7 and 8.1 bar (25 and 117 PSI). Open the water tap. Check for and eliminate any leaks. The appliance does not require any adjustment or water drain. ELECTRICAL CONNECTIONS Regulations require that the appliance is earthed. The manufacturer declines all liability for injury to persons or animals and for damage to property resulting from failure to observe the prescriptions. Make sure that the installation and the electrical connection are carried out by a qualified technician according to the manufacturer s instructions and local safety regulations. Ensure that the voltage indicated on the appliance data plate corresponds to the mains voltage. The plug of the appliance must be easily accessible even after installation so that the appliance can be unplugged if necessary. If this is not possible, we recommend the appliance is connected to the mains supply by means of a two-pole switch with minimum break distance between contacts of 3 mm, fitted at an easily accessible point. Do not use extension leads or adapters. After installation, make sure that the appliance is not standing on the power supply cable. 32 of 37
INSTALLATION INSTRUCTIONS LEVELLING THE APPLIANCE The refrigerator has two front and two rear wheels at the base of the product on each side that can be adjusted (see Figure A), or four wheels of which only the two front wheels can be adjusted (see Figure B). If the appliance seems unsteady or you want the doors to close easier, adjust the appliance's tilt, following the instructions below (depending on the model, as shown in the figures on the right). Figure A 1. Check the installation location to be sure you have at least 10 mm clearance on all sides including the top. 2. Connect the appliance to the mains power supply. 3. Move the refrigerator into its final position. 4. Open both doors and remove the plinth to locate the levelling bolts at the left and right of the refrigerator base. The top bolt (1) will adjust the rear wheel (if provided), and the bottom bolt (2) will adjust the front wheel. 5. Use the wrench provided to adjust the levelling bolts. Turn the levelling bolt clockwise to raise the appliance, or Figure B anti-clockwise to lower it. It may take several turns of the levelling bolts to adjust the tilt of the refrigerator. Note: do not unscrew the levelling bolts too much when lowering the appliance as they could fall out. Aligning the Doors If, after switching on the appliance and adjusting the refrigerator and freezer doors, the doors are misaligned, disconnect the appliance from the power supply and adjust both doors as indicated in the following diagrams. 33 of 37
