PREPARING FOR OPERATION IN WA- TER MODE Once the appliance has been installed, it is ready for use. However, its efficiency can be enhanced by ope- rating it in De'Longhi's patented water mode. The water in the tank increases the cooling po- wer of your Pinguino and at the same time redu- ces noise levels and electrical consumption. Compared to air, water reduces the temperature of the cooling circuit much more efficiently, be- fore being given off from the air exhaust hose in the form of vapour. Remember that: • You must always use salt-free clean water, tap water is recommended. • The length of time the water in the tank lasts depends greatly on environmental conditions such as temperature, humidity, insulation, the sun exposure of the room, the number of people present, etc. As an estimate, the water lasts about six hours. The BOOST function (see page 13) shortens the operating time to about 4 hours, but the cooling power and efficiency are increased. • When the water in the tank runs out, the light comes on and operation of the appliance switches automatically to air-air. The appliance is fitted with a resin limescale filter enabling normal tap water to be used. The resins reduce water hardness and therefore prolong the working life of the appliance. ke lightly. After about a minute, 1, 2, 3, 4 or 5 red squares appear, depending on the hardness of the water. The appliance can be set to three different water hardness levels soft (H1), medium (H2) and hard (H3). Determine the hardness of the water you will be using by comparing the red squares on the indicator paper with the table below. Water hardness indicator 19 Soft Level H1 20 Medium H2 Hard H3 To set water hardness, proceed as follows: 1. Set the appliance to stand-by. 2. Hold the FAN button on the control panel down for 10 seconds. The appliance emits a beep and H1, H2 or H3 is displayed. 3. Use the + or - buttons to set the hardness level according to the table below. Wait a few seconds for the setting to be memorized. The appliance emits another beep and goes back to stand-by. "CF" is displayed when the limescale fil- ter needs replacing. The efficacy of the filter depends on water hardness. It should, however, be replaced every five years. Setting water hardness Measure water hardness using the indicator paper provided. • Remove the indicator paper from its pack (R). • Immerse the paper completely in a glass of water for one second. • Remove the paper from the water and sha- The machine is set by default for medium hardness (H2). Filling the tank The water tank is located at the bottom of the appliance. Push in on the Tank Door (J) above the word PULL, and pull the tank out as far as it will go (fig. 12). Remove the cap and use a container (bottle, jug, watering can) to pour in the water (fig. 13/14). You can see when the tank is full through the filling hole. It holds a maximum of 21 pints (10 liters). 7
