24 WHAT IS THE WATER-AIR PINGUINO During the summer, you feel comfortable at a temperature of between 24 and 27° C with a relative humidity of about 50%. An air conditioner removes excess moisture and heat from the room where it is located. Compared with installed models, portable air conditioners have the advantage that they can be moved from one room to another in the home or be transported from one building to another. Hot air from the room is passed through a coil cooled by refrigerant gas. Excess heat and moisture are removed before the air is re- emitted into the room. In single unit models, a small part of this air is used to cool the refrigerant gas and then, when hot and damp, is discharged outside. In exclusive De'longhi water-air models, the heat is removed from the room through the cooling effect of the water which is obviously much greater than air. This gives this air conditioner unbeatable cooling efficiency. MODELS WITH R290 REFRIGERANT GAS The Pinguino ECO is a latest generation environmentally-friendly air conditioner. The Pinguino ECO does not, in fact, contain gases (CFC/HCFC) dangerous to the ozone layer or with a marked greenhouse effect (HFC). As well as reducing energy consumption, the high efficiency of the appliance also minimises impact on the greenhouse effect.

PREPARING FOR USE The instructions below will enable you to prepare your air condi- tioner for operation as efficiently as possible. Before use, make sure the air intake and outlet grilles are unob- structed. AIR-CONDITIONING WITHOUT INSTALLATION Just a few simple steps and your comfort is ensured with your appliance: • Fit the air exhaust hose in the housing at the back of the appliance (fig. 1). • Fit the window outlet to the end of the hose. • Place the air conditioner near a window or French window. • Adjust the length of the hose to reach the window. • Make sure the air exhaust hose is unobstructed. • Open the window or French window slightly and position the outlet (fig. 2). • If you have a double window, use the sucker provided to hold the two parts of the window together (fig. 3). You can also use the "adjustable bar" accessory. - Fit the window outlet in the housing in the bar (fig. 4) - Position the bar on the window sill and adjust until it fits in the guides of the blind (the length can be blocked with the plastic pin provided), then lower the blind (fig. 5). - Fit the air hose to the end of the window outlet. • Place the air conditioner near a window or French window and connect the end of the hose as shown in figure 6. Keep the air hose as short and free of curves as possible to avoid bottlenecks. 1 2 1 2 1 2 26 3 4 5 1 2 1 2 6
AIR-CONDITIONING WITH INSTALLATION If required, your appliance can also be installed semi-perma- nently (Fig. 7). Proceed as follows: • Drill a 106 mm dia. hole respecting the heights shown in fig. 8 and following the indications in figs. 9, 10 and 11. 27 30 cm 30 cm 7 10 MAX100 cm MIN 35 cm 8 106 9 11 in the window pane in the wooden kickboard of a French window in the wall: you are recommended to insulate the section of wall using suitable insulation. • Fit the flange accessory provided in the hole • Fit the hose in the housing at the back of the appliance (fig. 1). • Fit the end of the hose to the flange as shown in fig. 8. When the hose is not fitted, the hole can be closed with the flange cap. Keep the air hose as short and free of curves as possible to avoid bottlenecks. When installing the air conditioner semi-permanently, you should leave a door slightly open (as little as 1 cm) to gua- rantee correct ventilation. ✔
PREPARING FOR OPERATION IN WATER MODE Once the appliance has been installed following the instructions above, it is ready for use. However, its efficiency can be enhan- ced by operating it in the exclusive De'longhi water mode. The water in the tank increases the cooling power of your Pinguino and at the same time reduces noise levels and electrical con- sumption. Compared to air, water reduces the temperature of the cooling circuit much more efficiently, before being given off from the air exhaust hose in the form of vapour. Remember that: • You must always use salt-free clean mains water. • The length of time the water in the tank lasts depends greatly on environmental conditions such as temperature, humidity, insulation, the exposure of the room, the number of people present, etc. Indicatively it lasts about six hours. By using the WATERSAVE function (see page 34), the length of time can be extended to 10 hours, with a slightly lower cooling power and efficiency. • When the water in the tank runs out, the light comes on and operation of the appliance switches automatically to air- air. At the same time, the quantity of air given out from the rear hose increases. FILLING THE TANK You can fill the tank in one of two ways: 1) By using the jug provided or another recipient: Instead of the jug provided, you can use any recipient (plastic or glass bottle, watering can etc), providing the neck of the reci- pient enters the filling hole to avoid spilling water on the applian- ce. • Without using force, open the rear door completely, then remove the rubber cap (fig. 12). • Pour the water into the tank (fig. 13). When the tank is full, the water level window (fig. 14) becomes completely red. Indicatively, you will need to refill the jug three times to fill the tank completely. • After filling, put the rubber cap back in place, then close the door. 2) Using the extendible hose: • Without using force, open the rear door completely, then remove the rubber cap (fig. 12). Pull out the extendible hose (fig. 15) and place near a tap. • Fill the tank to the required level. • When the tank is full, the water level window (fig. 14) beco- mes completely red (about 14 l). • After filling, put the rubber cap back in place, then close the door. 28 12 13 14 15 Level window The tank does not have to be full to use the water function, but the length of time the appliance will operate in water mode will be shorter. When the level window has become completely red, do not add further water or it could overflow. The tank has no overflow prevention system. ✔ ✔

33 USING THE REMOTE CONTROL UNIT The first part of the controls on the remote control are the same as those on the control panel of the appliance (fig. 23). You should therefore refer to the instructions in the chapter Operating from the control panel to turn the appliance on and select the opera- ting mode (AIR CONDITIONING, DEHU- MIDIFYING, FAN, HEATING or SMART) and the fan speed. The following section describes the additional functions corre- sponding to the controls on the bottom part of the remote con- trol. BOOST FUNCTION (FIG. 24) Ideal for the summer to cool rooms rapidly. Activate by simply pressing the button. The appliance operates in air conditioning mode at maximum fan speed. While this function is selected, it is not possible to set the temperature or change fan speed. SELECTING THE TEMPERATURE SCALE (FIG. 25) Press the button to switch the temperature display from °C to °F and vice versa. SETTING THE TIME After having inserted the batteries, the clock on the display flashes until the time is set. Proceed as follows. • Press the or button until the correct time is reached. Hold the button down to run rapidly through first the minutes, then the tens of minutes and then the hours. • Once the correct time has been reached, release the button and press the SET button to confirm. • To cancel the settings programmed on the remote control and restore the original settings, press the RESET button lightly with the point of a pencil or pen. INSERTING OR REPLACING THE BATTERIES • Remove the cover on the rear of the remote control (fig. 22); • Insert two R03 “AAA” 1.5V batteries, making sure they are in the correct position (see the instructions inside the battery compartment); • Replace the cover. If the remote control unit is replaced or discarded, the bat- teries must be removed and disposed of in accordance with current legislation as they are harmful to the environ- ment. 22 ✔ 33 23 25 24
SLEEP FUNCTION (FIG. 26) This function is ideal for the night as it gradually reduces opera- tion of the appliance. To set this function correctly: • Select the operating mode (air conditioning, dehumidifying, smart or heating (certain models only) as described above. • Press the button. The appliance operates in the previously selected mode with low fan speed. The SLEEP function maintains the room at optimum temperature without excessive fluctuations in either temperature or humidity and with silent operation. Fan speed is always at minimum, while room temperature and humidity vary gradually to ensure the most comfortable condi- tions. During air conditioning, the temperature increases by 1°C after 60 minutes and a further 1°C after 2 hours. In dehumidifying mode, the dehumidifying power of the appliance is partially reduced every hour for the first two hours. In heating mode, the temperature drops by 1°C every hour, three times. IONISER FUNCTION (CERTAIN MODELS ONLY) (FIG. 27) The ioniser is an electronic component which releases negative ions into the air. Rooms with a clean pleasant atmosphere have been shown to have an abundance of negative ions, while rooms with stale air contain abundant positive ions. The ioniser restores the correct balance between the two types of ion, reducing dust in the air and generating a pleasant sensa- tion of well-being. This button activates the ioniser present in cer- tain models. This function can be activated in all operating modes. WATERSAVE FUNCTION (FIG. 28) This function is designed to increase the operating time of the appliance when operating in water mode and can be activated in air conditioning and SMART mode. When the button is pressed, the appliance is slightly less efficient, but consumption of water in the tank is considerably reduced. With a full tank, the appliance normally operates for six hours. With this function activated, the operating time increases to 10 hours, avoiding the need to top up frequently. If the water runs out when this function is active, the quantity of air given out from the rear hose increases and the light comes on. To restore operation in water mode, fill the tank. SWING FUNCTION Not available in these models. 34 26 27 28

Error messages are displayed on the appliance display. IF…IS DISPLAYED, WHAT SHOULD I DO? LOW TEMPERATURE (frost prevention) PROBE FAILURE (sensor damaged) The appliance is fitted with a frost protection device to avoid excessive formation of ice. The appliance starts up again automatically when the defrosting process is completed. If this is displayed, contact your local authorised servi- ce centre. IF…IS DISPLAYED, WHAT SHOULD I DO? HIGH LEVEL (safety tank full) CLEAN Empty the internal safety tank, following the instruc- tions in the "End of season operations" paragraph. If this reoccurs, contact your local authorised servi- ce centre. This message appears after about 500 hours of opera- tion in water mode and indi- cates that the appliance requires descaling as descri- bed in the "descaling" para- graph. After descaling or if the alarm reappears too soon after the last descaling (carried out before the message is dis- played), reset the alarm by holding the button down for 10 seconds.
36 TIPS FOR CORRECT USE To get the best from your air conditioner, follow these recom- mendations: • close the windows and doors in the room to be air conditio- ned (fig. 33). When installing the air conditioner semi-perma- nently, you should leave a door slightly open (as little as 1 cm) to guarantee correct ventilation. • protect the room from direct exposure to the sun by partially closing curtains and/or blinds to make the appliance much more economical to run (fig. 34); • never rest objects of any kind on the air conditioner; • do not obstruct the air intake and outlet (fig. 35). Leave both grilles free; • make sure there are no heat sources in the room. • never use the appliance in very damp rooms (laundries for example). • never use the appliance outdoors. • make sure the air conditioner is standing on a level surface. If necessary, place the castor locks under the front wheels. 33 34 35 36 close doors and windows close curtains do not cover the appliance AIR PURIFYING FILTERS The appliance is fitted with a dust filter which retains impurities in the air drawn in from the room. Certain models also include other filters with a high filtering capa- city, namely a silver ion filter and a 3M® electrostatic filter. SILVER ION FILTER The silver ion filter not just retains dust particles, but also has an efficient antibacterial action. It also greatly reduces concentra- tions of irritants such as pollen and spores. The filter is treated with small particles of silver (on the scale of mil- lionths of a millimetre) which are able to block the multiplication of and kill any nearby bacteria or spores. 3M® ELECTROSTATIC FILTER The 3M® electrostatic filter retains the finest dust particles, thus enhancing the filtering capacity of the appliance. FITTING THE FILTERS TO THE GRILLE The appliance can be used with just the dust filter already inser- ted in the grille. To use the two supplementary filters (if provided with your model), remove them from the packaging and attach them to the dust filter, inserting them under the special clips (fig. 36). If you decide not to use them, keep them sealed in the packa- ging. 3M® filter Silver ion filter
CLEANING Before cleaning or maintenance, turn the appliance off by pres- sing the button on the control panel or remote control, wait for a few seconds then unplug from the mains socket. CLEANING THE CABINET You should clean the appliance with a slightly damp cloth then dry with a dry cloth. Never wash the air conditioner with water. It could be dan- gerous. Never use petrol, alcohol or solvents to clean the appliance. Never spray insecticide liquids or similar. CLEANING THE AIR FILTERS To keep your air conditioner working efficiently, you should clean the dust filters every week of operation. Dust filter supplied with all models The filter is housed in the intake grille. To clean the filters, proceed as follows: • Remove the intake grille by pulling it outwards (fig. 37). • Remove the dust filter by detaching it from the grille (Fig. 38). • Use a vacuum cleaner to remove the dust collected on the filter. If it is very dirty, immerse in warm water and rinse a num- ber of times. The water should never be hotter than 40°C. • After washing, leave the filter to dry completely. • To replace, put the filters back in the intake grille then attach the intake grille to the appliance. Silver ion filter and 3M® electrostatic filter (certain models only) These two filters are located behind the dust filter. To clean the dust filter, the two supplementary filters must be tem- porarily removed. To clean, use a vacuum cleaner at medium power. The silver ion filter can be washed with cold water. Leave to dry completely and replace. It should be replaced at least once every two seasons. The 3M® filter is not washable and must replaced at the end of the season or when it is exhausted and no longer efficient. The silver ion filter and 3M® filter can be bought from shops selling De'longhi accessories or authorised service centres. 37 37 38 ✔ ✔ ✔
38 RECOMMENDED END OF SEASON OPERATIONS • Descale as described in the following paragraph. • Empty the water from the tank and internal circuit by extrac- ting and opening the two hoses inside the rear door (fig. 39). • Operate the appliance with the water tank empty in fan only mode for about half an hour. This dries any water remaining inside the appliance. • Turn the appliance off and unplug from the mains. • Remove the air exhaust hose. • Clean the dust filters and (in certain models) the air purifying filters. • Place the power cable in the special rear cable compart- ment (fig. 40). • Cover the appliance to avoid dust. DESCALING When using the appliance in water mode, lime scale will inevi- tably form and must be removed to maintain efficiency. After about 500 hours of operation, the appliance therefore warns that descaling is required by displaying the message C CL L (CLEAN). Descale the appliance. • Turn off the appliance and unplug from the mains. Empty all water from the inside of the appliance through the drain hoses (fig. 39). • Close and replace the drain hoses. Pour 0.5 l of descaler (one bottle) and 1.5 l of clean water into the tank. • Plug in and operate the appliance in air conditioning mode with the BOOST function selected until the "no water" symbol appears on the display. • Turn off the appliance and unplug from the mains.
