De'Longhi PACW110E Owner's Manual

What is the Water-Air Pinguino?

During the summer, you feel comfortable at a temperature of between 75°F and 81°F (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 duct 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

Air-Conditioning Without Installation

Follow these simple steps for comfortable operation:

• Fit the air exhaust hose (K) in the housing (G) at the back of the appliance (see figure 1).
• Fit the window outlet (N) to the end of the hose.
• Place the air conditioner near a window or French window.
• Adjust the length of the air exhaust hose to reach the window.
• Make sure the air exhaust hose is unobstructed.
• Open the window or French window slightly and position the window outlet (see figure 2).

For optimum results:

• If you have a sash window, place the window bracket (Q) on the window sill, extend it fully within the window frame, fix it with the locking pin, then lower the window onto the bracket. Insert the window outlet (N) of the exhaust hose (K) into the slot, then connect the hose to the air conditioner (see figure 3).
• Thanks to the locking pins, the window bracket can also be used for sliding windows. Position the hole of the window bracket to allow correct installation of the exhaust hose (see figure 4).
• If the windows are large, use the window bracket extension (R) to cover your window aperture, extending it to the required length and blocking it with the locking pins (see figure 5). Ensure you do not cover the hole for the window outlet.

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

Diagrams 1-5 illustrate the setup process for air conditioning without permanent installation, showing hose connection, window outlet placement, bracket usage, and extension usage.

Air-Conditioning With Installation

If required, your appliance can be installed semi-permanently (Fig. 6).

Proceed as follows:

• Drill a 4.17 inches (106 mm) diameter hole respecting the heights shown in fig. 7 and following the indications in figs. 8, 9, and 10.
• Fit the wall flange (P) into the hole.
• Fit the air exhaust hose (K) in the housing at the back of the appliance (fig. 1).
• Fit the end of the air exhaust hose to the wall flange as shown in fig. 7. When the air exhaust 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, leave a door slightly open (as little as 1/2" (1cm)) to guarantee correct ventilation.

Diagrams 6-10 illustrate semi-permanent installation options: general setup (Fig. 6), hole placement and dimensions (Fig. 7), window pane installation (Fig. 8), wooden kickboard installation (Fig. 9), and wall installation with insulation recommendation (Fig. 10).

Preparing for Operation in Water Mode

Once installed, the appliance is ready for use. Its efficiency can be enhanced by operating it in the exclusive De'Longhi water mode. Water in the tank increases cooling power and reduces noise levels and electrical consumption. Water cools the circuit more efficiently than air.

Remember:

• Always use salt-free tap water.
• The duration the water lasts depends on environmental conditions (temperature, humidity, insulation, room occupancy). It typically lasts about six hours. The WATERSAVE function (page 13) can extend this to 10 hours with slightly lower cooling power.
• When the water runs out, a light comes on, and the appliance automatically switches to air-to-air operation, increasing the air output from the rear hose.

Filling the Tank

You can fill the tank in two ways:

1. By using the water jug provided: Use the provided jug or any other plastic/glass bottle or watering can with a narrow neck to avoid spilling water.
   • Open the water fill door (J) completely, then remove the rubber cap (fig. 11).
   • Pour water into the tank (fig. 12). When full, the water level window (fig. 13) turns completely red. You will need to refill the jug approximately three times.
   • After filling, replace the rubber cap and close the door.
2. Using the extendible hose:
   • Open the water fill door (J) completely, then remove the rubber cap (fig. 11). Pull out the extendible hose (fig. 14) and place it near a tap.
   • Fill the tank to the required level. The water level window (fig. 13) will turn completely red when full.
   • After filling, replace the rubber cap and close the door.

Diagrams 11-14 illustrate the water filling process: opening the fill door and removing the cap (Fig. 11), pouring water into the tank (Fig. 12), the water level window (Fig. 13), and using the extendible hose (Fig. 14).

The tank does not need to be full for the water function, but operating time will be shorter. Do not add water if the level window is completely red, as the tank has no overflow prevention system.
