WHAT IS THE WATER-AIR PINGUINO

During the summer, you feel comfortable at a temperature of between 24 and 27^ with a relative humidity of about 50% .

An air conditioner removes excess moisture and heat from the room where it is located.

Compared with wall mounted 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.

PREPARING FOR USE

The instructions below will enable you to prepare your air conditioner for operation as efficiently as possible.

Before use, make sure the air intake and outlet grilles are unobstructed.

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 (N) to the end of the hose (K).
• 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 (Q) provided to hold the two parts of the window together (fig. 3).

You can also use the "adjustable bar" accessory (T).

• 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 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 (fig. 7).
• Remove the cap at the back of the appliance (G) and replace with the drain hose plus cap (U) as shown in figure 6.

This enables the condensate to be drained more easily at the end of the season.

See the section: "END OF SEASON OPERATIONS".

• Keep the air hose as short and free of curves as possible to avoid bottlenecks.

Air-conditioning with installation

If required, your appliance can be installed semipermanently (Fig. 8).

Proceed as follows:

• Drill a 134mm dia. hole in an outside wall or through a window pane, respecting the heights shown in fig. 9.

• Fit the flange accessory (S) provided in the hole following the indications in figs. 10, 11 and 12.

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 air exhaust hose (K) in the housing at the back of the appliance (fig. 1).
• Fit the end of the hose to the flange (S). When the hose is not fitted, the hole can be closed with the flange cap.
• Remove the cap at the back of the appliance (G) and replace with the drain hose plus cap (U) as shown in figure 6. This enables the condensate to be drained more easily at the end of the season. See the section: "END OF SEASON OPERATIONS".

i Keep the air hose as short and free of curves as possible to avoid bottlenecks.

i When installing the air conditioner semipermanently, you should leave a door slightly open, as little as 1cm to guarantee correct ventilation.

PREPARING FOR OPERATION IN WATER MODE

Once the appliance has been installed, it is ready for use.

However, its efficiency can be enhanced 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 consumption.

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.

The BOOST function (see page 30) 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. At the same time, the quantity of air given out from the rear hose increases.

The appliance is fitted with a resin lime-scale filter enabling normal tap water to be used.

The impregnated resins reduce water hardness and therefore prolong the working life of the appliance.

i "CF" is displayed when the limescale filter 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 (V).

• Immerse the paper completely in a glass of water for one second.

• Remove the paper from the water and shake 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.

Kind of water used	Levels
0 - 19°F soft	H1
20 - 36°F Medium	H2
> 36°F 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 memorised. The appliance emits another beep and goes back to stand-by.

The machine is set by default for medium hardness (H2).

Filling the tank

The water tank is located at the bottom of the appliance. Remove the tank by inserting the hand through the door above the word "PULL" (fig. 13) and pulling the tank out as far as it will go. Remove the cap and use a container (bottle, jug, watering can) to pour in the water (fig. 14/15). You can see when the tank is full through the fil

ling hole. It holds a maximum of 10 litres.

Replace the cap correctly and close the tank, pushing it in as far as it will go. The tank hole has a mesh filter to prevent the introduction of foreign matter. If necessary, this filter can be unscrewed and removed for cleaning under running water.

• 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.
• Do not fill above the level of the hole to avoid the water overflowing. The tank has no overflow prevention system.

Replacing the limescale filter

Turn the appliance off and unplug from the mains.

Make sure there is no water in the appliance by emptying the tank and internal tray as described in the section: "End of season operations".

Lay the appliance on its back as shown in figure 17. Rest it on a towel or piece of cardboard to avoid scratches or damage. Remove the filter cover by unscrewing the four screws (fig. 17).

Remove the filter delicately and loosen the two ties, making sure the two hoses connecting the filter do not slip inside the appliance. Fit the new filter, following the same procedure in reverse (fig. 16/15). The pawl on the filter (see figure) indicates the correct direction. The pawl must always be towards the inside of the appliance and point "A" must be facing upwards.

16

Water may leak out while replacing the limescale filter. You should therefore perform the operation in a suitable location.
i After replacing the filter, wait at least an hour before starting the machine again.
When the filter has been replaced, turn the alarm off by pressing the ON/STAND-BY button (15) for 10 seconds.

The appliance emits a beep.

AIR PURIFYING FILTERS

This appliance is fitted with two dust filters to maintain efficiency.

One is at the back near the intake grille, the other is at the side (fig. 37-38).

Certain models have a silver ion dust filter and an additional electrostatic filter in the grill at the back

Silver ion filter

This dust filter is treated with silver ions which not just retain dust particles, but also have an efficient antibacterial action. It also greatly reduces concentrations of irritants such as pollen and spores.

Electrostatic filter

The 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 filters already inserted 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. 39).

If you decide not to use it, keep it sealed in the packaging.

• Do not use petrol, alcohol or solvents to clean the appliance.

Do not 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.

Cleaning the dust filters supplied with all models

Each 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 number of times.

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.

Cleaning of the silver ion filter and of the electrostatic filter (certain models only)

To clean the silver ion dust filter, the electrostatic filter must be temporarily removed.

To clean the filters, use a vacuum cleaner at medium power.

The silver ion filter can be washed with lukewarm water. Leave to dry completely and replace.

The electrostatic filter is not washable but it should be replaced at least once every two seasons.

The electrostatic filter can be bought from shops selling De'longhi accessories or authorised service centres.
