USER MANUAL DH131 DELONGHI

WARNING: Very carefully dispose of the cut off plug after removing the fuse: do not insert in a 13 Amp socket elsewhere

in the house as this could cause a shock hazard. With alternative plugs not incorporating a fuse, the circuit must be protected by a 15 Amp fuse. If the plug is a moulded-on typer, the fuse cover must be re-fitted when changing the fuse using a 13 Amp Asta approved fuse to BS 1362. In the event of losing the fuse cover, the plug must NOT be based until a replacement fuse cover can be obtained from your nearest electrical dealer. The colour of the correct replacement fuse cover is that as marked on the base of the plug. B) If your appliance is not fitted with a plug, please follow the instructions provided below: Electrical connection (U.K. only) WARNING - THIS APPLIANCE MUST BE EARTHED IMPORTANT The wires in the mains lead are coloured in accordance with the following code: Green and yellow: Earth Blue: Neutral Brown: Live

As the colours of the wires in the mains lead may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows: The green and yellow wire must be connected to the terminal in the plug marked with the letter E or the earth symbol or coloured green or green and yellow. The blue wire must be connected to the terminal marked with the letter N or coloured black. The brown wire must be connected to the terminal marked with the letter L or coloured red. Presentation The dehumidifier is an appliance which removes the humidity from the air, allowing the relative humidity to be controlled and thus enabling a room to be become an area of comfort and wellbeing. It is a compact appliance fitted with wheels and handles, and is thus easy to move around. It s use is advisable in all rooms where there are problems of excess humidity, such as bathrooms, laundries, kitchens, basement rooms, cellars, etc.. The technical specifications of the appliance are shown on the data plate placed on the inside of the tank cavity*. Read this instruction booklet carefully before installing and using the appliance. In this way, you will obtain the best possible results and maximum operating safety. It is the level of relative humidity which determines an environment’s degree of comfort. Experts have established that the optimum conditions, both for the human organism and for preserving objects, vary between 40° and 60° relative humidity. It is thus advisable to keep environments within these parameters. Air always naturally contains a certain amount of water in the form of water vapour which determines its degree of humidity. Nevertheless, the air’s ability to retain water vapour is limited and depends on the temperature: the higher the temperature the greater the amount of water that can be contained in the air. Absolute humidity (A.H.) indicates the amount of water vapour contained in 1 kg of air and is expressed in grams. Relative humidity (R.H.) is the relationship between the amount of water contained in 1 kg of air and the maximum amount able to be contained at those atmospheric conditions, expressed as a percentage. In other words, we can imagine the air of a particular environment at a certain temperature as a container of a fixed capacity, for example 10 litres. If we imagine half filling it with water we can say that the container is 50% full (relative humidity), and that the amount of water contained is 5 litres (absolute humidity). When the container is completely full we say that it is “saturated”, that is, that we are in the presence of 100% relative humidity. With an increase in the temperature it is as if we increased the capacity of the container. Thus the air at 20° C is like a 10-litre container while the air at 30° C is like a 20-litre container.

rubber cap 110 B) Continuous External Discharge If you need to have the appliance working for a long period of time but are unable to empty the canister repeatedly, you can allow the condensation to discharge into a water drain. To do this all you have to do is to arrange the canister and the hose supplied as follows:

1) Remove the rubber stopper from the canister spout.

Make a hole on the inside of the canister spout. We recommend using a drill with a fine bit Fig. 2

3) Attach the rubber hose to the spout.

You can pass the hose through the panel door, taking advantage of the fact that the canister spout has been lined up opposite it. To achieve this all you need do is to make a hole in the plastic with a cutter following the groove marked as a guide (fig. 3).

WARNING: Check that the hose does not have to go “uphill”, or the water could be left inside the

canister. Keep hold of the rubber stopper: it can be used for plugging the canister spout if the canister is used for discharging in the future. Installation Place the appliance in the room that you wish to dehumidify. It is essential to leave a space of at least 50 cm. around the appliance in order to ensure adequate ventilation. The condensation can be discharged in one of two ways: A) Discharge into the canister The condensation generated by the dehumidifier can be collected directly in the canister which is located inside the appliance (fig. 1). The canister has a capacity of over 6 litres. It is easy to extract when it needs to be emptied. It has an ergonomic form and is equipped with a handle which makes it easy to carry and to empty. Fig. 2 Fig. 3 Fig. 1 Tank Control System The dehumidifier is equipped with an exclusive intelligent device which checks that the appliance is working properly. A warning lamp placed on the control panel comes on to warn the user when:

1. the tank is full ➛ empty the tank

2. the tank is missing ➛ put the tank back into position

3. the tank is badly positioned ➛ position it correctly

4. you are using the continuous discharge and there is a blockage in the hose or the hose goes

“uphill” ➛ a) empty the tank; b) remove the blockage or get round the “uphill” Once the cause has been removed, the warning lamp goes off and the appliance starts working again.11 Electrical connections Before connecting the appliance to the power supply, check the following:

• The mains power supply must correspond to the power supply shown on the rating plate.

• The power socket and the electrical circuit must be adequate to bear the required load.

• The power socket must match the plug. If not, have the plug replaced by qualified personnel.

• The power socket must be adequately earthed. The manufacturer declines any responsibility for failure to comply with these safety regulations. The appliance is manufactured in accordance with EEC Directive EN 55014 relative to the suppression of radio interference.

1) Plug the appliance into the power socket. The pilot lamp lights to show that the appliance is

3) Check that the “Tank control system” pilot lamp is off (see the previous page).

4) Turn the humidistat knob in an anticlockwise direction to the CONTINUOUS position: the

dehumidifier pilot lamp will come on to signal that the appliance has started to work.

To switch off the appliance, turn the humidistat in an anticlockwise direction to the minimum setting. Wait for an hour before switching the dehumidifier on after it has been transported. To guarantee maximum life and efficiency, the appliance will only really begin dehumidifying three minutes after being switched on, when the “pause” signal lamp goes off. Some Users’ Tips Significant relative humidity values are shown on the humidistat. In particular, by positioning the knob between 60° and 40° (or between 2 and 3) you will set the appliance up to guarantee that it will automatically maintain comfortable conditions. For maximum comfort, we recommend selecting the minimum fan speed. At first the dehumidifier will absorb large quantities of humidity and will continue to do so until the relative humidity has been reduced. From this point onwards, the appliance will absorb less humidity: this does not mean that the dehumidifier is not working properly but rather that the humidity in the air has diminished and that the appliance will continue to maintain the desired level of humidity efficiently. In cellars and basements, however, it will not be necessary to lower the level of relative humidity very much, e.g. in order to conserve foodstuffs: regulate the humidistat to a setting between 80% and 60% (or between 2 and 1). It is advisable to have the maximum fan speed in order to get the room quickly to the desired level of humidity. In laundries and in all areas where you need to reach the lowest levels of humidity quickly the maximum speed should be selected. Set the humidistat between 40% and 20% (or between 3 and 5) relative humidity, or to CONTINUOUS setting if you want the appliance to continue dehumidifying until a new setting is made.

Cleaning the cabinet

• Clean the appliance using a damp cloth and dry using a dry cloth.

• Do not use jets of water, petrol, methylated spirits or solvents to clean the appliance.

• Never spray the appliance with insecticides or similar products as they may spoil its appearance. Cleaning the air filter

• As a rule the filter should be cleaned weekly.

• In order to remove the air filter, open the canister panel, remove the canister and extract the filter by pulling it downwards (fig. 4).

• Use a vacuum cleaner to remove the dust that builds up on the filter. If the filter is very dirty, wash it in warm water and rinse several times. The temperature of the water should not exceed 40° C. After washing the filter, allow it to dry completely before putting it back in the appliance. If the appliance is not used for long periods

• Disconnect the plug from the power socket and empty the canister.

• Clean the filter and put it back in.

• Protect the appliance from dust by covering it with a plastic bag. Warnings
