►►►2. GENERAL DESCRIPTION OF

THE UNIT (FIG. 1) The dehumidier is an appliance suitable for controlling the humidity of the room it is placed in. Dehumidication is carried out via a refrig- eration cycle which is based on the physicalen

principle whereby the air, when it comes into contact with a cold surface, wets it, releasing humidity in the form of condensation drops. The equipment is made up as follows (FIG. 2): Air is extracted from the appliance: it passes through the washable lter (1), the aluminium coil (evaporator) (2), the hot exchanger (con- denser) (3), the fan (4) and nally the dehu- midied air ows out and is recirculated into the room through the grille. The condensed water is collected in the tank (5). A micros- witch stops the appliance when water in the tank reaches a certain level. An electronic board (6) manages the correct operation of the appliance. This appliance is equipped with a hot gas de- frost system, which ensures the correct opera- tion of the dehumidier within the temperature and humidity range specied in the technical data table. ►►2.1. REFRIGERANT CIRCUIT The refrigerant gas used in these units is R1234yf. The refrigerant circuit is built in com- pliance with current standards. Flammable material hazard. This unit is hermetically sealed and contains uorinated gas R1234yf GWP (R1234yf) = 4. ►►►3. PRELIMINARY OPERATIONS

Remove the packaging taking care not to dam- age the unit. Dispose of the packaging prod- ucts (wood, plastic, cardboard), taking them to the specialised collection or recycling centres (follow the local regulations in force). CAUTION: Depending on the model, as- semble the appliance, with any handles, wheels and all relevant hardware (FIG. 3) housed inside the packaging before commis- sioning. ►►3.2. INSPECTION All units are factory assembled and wired (except for certain components). Upon re- ceiving the unit, it must be immediately and thoroughly inspected, checking that it has not been damaged during transport or that no parts are missing. Before use, specically check for any dents on the external metal panels, including those in the tank compartment. Also check that the cable, plug and relevant insulation are intact. Otherwise, it is FORBIDDEN to con- nect and start the unit, which must be sent to an authorised service centre. ►►3.3. OPERATING PRINCIPLES CAUTION: To ensure correct operation of the appliance, it is recommended to op- erate the unit within the limits shown on the technical data table. ►►3.4. POSITIONING Set up the appliance to ensure an adequate air ow. CAUTION: Make sure that the appliance is placed in such a way so as to prevent contact with water. ►►3.5. SERVICE AREA The hot air expelled by the fan must not be obstructed. Avoid hot air recirculation between suction and delivery to prevent compromising the performance of the unit or even interrupt- ing normal operation. CAUTION: The equipment must not be placed in cramped environments, which do not allow adequate distribution of the air from the air outlet grille into the room. CAUTION: Do not place or hang objects on the front panel, it may cause damage to the unit.en

►►3.6. GENERAL INFORMATION CAUTION: Disconnect the power plug from the socket before carrying out any main- tenance operation on the electrical part. CAUTION: Check that the supply voltage corresponds to the unit's operating data (volt- age and frequency) shown on the data plate on the dehumidier. The appliance is tted with a power cable for correct operation. CAUTION: The earthing connection is mandatory. ►►►4. START-UP ►►4.1. PRELIMINARY CHECKS IMPORTANT: For dual voltage mod- els (...DV), check the position of the trans- former switch (220-240V / 110-120V). If the set voltage does not match that supplied by the mains, the voltage must be adapted (FIG. 4). Loosen the two lid screw fasten- ers, shift/press the switch onto the voltage value supplied and mount the lid again. CAUTION: Check that the power cord is properly connected. CAUTION: Check that all the cover panels are in the correct position and are locked via xing screws before commission- ing. CAUTION: Always disconnect the power supply if the appliance is not used for a long period of time. ►►4.2. CONTROL PANEL (FIG. 5) The units are equipped with a luminous signal- ling panel that indicates their operating status. A brief description of their meaning is provided below. CONTROL PANEL: LED: ►POWER LED: This LED is on if the unit is in the “ON” status, but in stand-by mode (i.e. the compressor is o󰀨). ►ALARM LED: This LED is on when the unit is in alarm. The display will show the error message. ►WORKING LED: This LED is on when the compressor is running. The LED ashes when the dehumidier is waiting to restart or is in defrost mode. The LED turns o󰀨 when the desired amount of humidity has been reached in the “ON” status. ►FULL LED: This LED is on when the con- densate tank is full or if the pump is in alarm. BUTTONS: ►ON/OFF: To turn on the dehumidier, simply press the “ON/OFF” button. Based on the relative humidity set, the appliance starts working. When the room humidity reaches the required level, the appliance goes into stand-by mode and the unit stops, but re- mains in the “ON” status (POWER LED on). If the room humidity rises again, exceeding the previous set point, the dehumidier re- starts again. Press the “ON/OFF” button to turn o󰀨 the appliance (with the appliance o󰀨, the display continues to indicate the relative humidity in the environment). ►“-” / “+” (HUMIDITY SET): Press the “-” / “+” buttons to set the relative humidity desired. The display will start ashing, showing the new reference set point. After a few sec- onds the display stops ashing and the new humidity set point has been detected by the electronics. It is possible to operate the appliance re- gardless of the degree of humidity present in the environment. By pressing the “-” but- ton until the “CONT” message appears on the display, the appliance will operate con- tinuously. ►HOURS: Press the “HOURS” button to view the working hours of the appliance.en
