4 1 Safety and Installation 1.1 Safety measures Before starting work on an appliance, check that the earth in the lodgings is working properly by using an appropriate tool and follow the instructions described/illustrated on the Electrolux Learning Gateway portal This platform is not fitted with an ON/OFF switch. Before you access internal components, take the plug out of the socket to disconnect the power supply. When the servicing is completed, ensure that all the connections have been made properly and that all the appliance s safety conditions are as good as new. The connection between the earth terminal and the earthed metallic parts must have a low resistance. Servicing must be performed using a tool suitable for measuring the earthing connection in compliance with the IEC/EN standard and follow the instructions described/illustrated on the Electrolux Learning Gateway/Metratester portal The resistance reading taken during the trial should not exceed 0.1 Ohm. If the compressor needs to be replaced, check the earthing resistance between the earth contact and the accessible metallic part on the condenser. In the event of handling/replacing the electronic circuit board, use the ESD (Cod /4) kit to avoid electrostatic discharges damaging the electronic circuit board, see S.B. No All the work to be performed inside the appliance requires specific skills and knowledge and may only be carried out by qualified and authorised service engineers. Some of the components in the mechanical part could cause injuries, so wear suitable protection and proceed with caution. If the compressor needs to be replaced, it must be welded and not connected via Lokring type connections. Always empty all the water from the condensation tank before laying the appliance on its side. If the appliance has to be placed on its side for maintenance or another reason, lie it on its left side, to avoid the risk of any residual water falling onto the main circuit board. When replacing components, please refer to the code shown in the list of spare parts relating to the appliance. Technical Support - MP 4/ Rev. 00

5 1.2 Installation Remove the external film. If necessary use a cutter blade. Take off the cardboard cover and remove the corner elements. Remove the polystyrene base and set the tumble dryer in position. The tumble dryer weighs approximately 60 kg Adjust the four feet so that the appliance is installed perfectly level (using a spirit level), to allow for the correct flow of condensation water into the purposeprovided tank. The feet must never be removed. A gap must always be left between the bottom of the tumble dryer and the floor to prevent the appliance from overheating. Technical Support - MP 5/ Rev. 00

7 3 Operating characteristics and construction 3.1 Principle of the heat pump Operating principle Operating principle with auxiliary condenser 1 Condenser. 2 Evaporator. 3 Drum. 4 Condensation collection tray. 5 Condensation collection tank. 6 Compressor. 7 Air circulation fan. 8 Capillary. 9 NTC. 10 Compressor cooling fan. 11 Condensation water suction pump. 12 Auxiliary condenser. The cycle of the tumble dryer heat pump consists in evaporating, compressing, condensing and expanding the refrigerant R134a. By pressing the START/PAUSE button the drying cycle begins, the gas in the circuit is conveyed by the compressor (6) to the condenser (2), where at the outlet the circulation pipe known as capillary (8) narrows. This capillary slows down the release of gas and ensures that the pressure inside the condenser (2) increases bringing the gas to a liquid status and a pressure level of around 27 bar. This rise in pressure subsequently increases the temperature of the gas that is now liquid inside the condenser (2) reaching around 53 C. The air circulated by the fan (7) passes through this condenser (2) overheating before entering the drum (3) where the washing is located. The evaporator (1) is located at the capillary outlet (8) with the gas circulation pipe being larger than the capillary which thus expands the hot, liquid gas coming from the condenser (2). This gas expansion means that the gas in its liquid state once again becomes a gaseous state causing the gas itself to cool and subsequently cooling the entire evaporator, bringing it to a temperature of around 20 C. Technical Support - MP 7/ Rev. 00

8 Then, by now hot air is circulated by the fan (6) and passes through the washing in the drum (3) absorbing humidity and reaches the evaporator (1) humid and hot. The latter which is now at a lower temperature thanks to the expansion of the gas ensures that all the humidity in the circulating air condenses. The condensed water created is collected in a tray (4) and conveyed via a pump to the tank (5) located above the drum. At this point, the air is now cold and dry and goes through the condenser (2) again, once again overheating before entering the drum (3) and the gas now cooled in the evaporator (1) returns to the compressor where it will once again be compressed and sent into the condenser (2) re-starting the cycle. The entire gas evaporating and compressing system is kept in balance by a NTC (9) located at the entrance to the capillary (8). This collaboration with the main circuit board ensures that if the outgoing temperature from the condenser surpasses a certain level a fan (10) located in front of the compressor starts working and lowers the temperature. In the models with auxiliary condenser, the operating principle remains the same and the only single variant is in the auxiliary condenser positioned in series to the main condenser. This ensures that the whole system is better balanced, thus increasing performance. 3.2 Power supply management Depending on the characteristics of the main circuit board, and irrespective of the model, the appliance can be completely cut off from the mains, or alternatively set to a special, lower energy consumption mode. When the 0 Watt power supply circuit is inserted in the main circuit board, the appliance consumption is automatically cut to 0. Without this circuit, for users to get a power absorption of 0 (zero) Watts, they have to cut off the electricity supply by unplugging the appliance. In either case, the user interface behaviour is the same. To turn the appliance on, simply press the ON/OFF button briefly. The appliance beeps once (if the buzzer is enabled), and depending on the selected programme, the display shows the time required to complete drying. To turn off the appliance, hold down the button for approximately 1 second. After this time, the user interface beeps once (if the buzzer is enabled) and all the lights and the display are turned off. After turning off the dryer, all the options selected and the programme are deleted. Behaviour in Stand-Off mode In order to minimise electricity wastage when the cycle is not under way, appliances in this platform offer the auto-off function which, when teamed with the Zero-Watt circuit, provide two ways of enabling a low consumption mode: 1. When you press the ON/OFF button to turn off the appliance, the supply voltage is cut off and the tumble dryer is secured (motor off, display off, etc ), the cycle and any options selected are reset, so that the next time the appliance is turned on, it is ready to perform a new programme. 2. If, during the programme and options selection phase or after the end of the cycle, the appliance receives no further instructions for at least 5 minutes, it is automatically turned off (for energy savings in conformity with the standards on energy consumption). - If this occurs during the setting phase, the programme and the options selected are cancelled and the basic programme appears when the appliance is turned back on. - If the cycle has ended, all the settings are stored so that when the appliance is turned back on, the user can see that the cycle ended normally, and can restart it if necessary. If an alarm occurs while a programme is under way, the auto off function is disabled, and an alarm is displayed. Technical Support - MP 8/ Rev. 00
