Installation

Permanent Installation

The Pinguino accessories include one wall vent for exhausting your Pinguino. Once installed, this vent is the only item needed for using Pinguino.

Permanent installation outlet holes must be in an exterior wall and opening diameter should not exceed 4"1/2.

• Figure 2: Diagram showing permanent installation through a window pane, requiring a 4.17-inch diameter hole.
• Figure 3: Diagram showing permanent installation through the wooden base of a door or window, requiring a 4.17-inch diameter hole.
• Figure 4: Diagram showing permanent installation through a wall, requiring a 4.17-inch diameter hole and a 1-inch gap for air entry.

In case of fixed installation, air discharged from the rear hose has been extracted from the room where the appliance is installed. Check that the room (especially if small) is not “air-tight”; a drop in pressure would cause irregular functioning, which could consequently activate the reset switch. Air entering through door and window cracks is normally sufficient. If deemed necessary, leave a door ajar (approx. 1/2 inch is enough).

Temporary Installation

Note: In both cases (permanent and temporary installations) make sure that the Pinguino is positioned on level ground. If necessary, use the two caster stops for the front casters.

This installation makes it easy to use Pinguino in any room, provided there is a window or a door: it allows you to use the Pinguino immediately (Fig. 5).

Suction discs may be used to keep the window or door closed (Fig. 6).

Note: Additional exhaust hoses are available through DeLonghi America. For best results, we do not recommend using more than one.

Pinguino is equipped with an adjustable window bracket. If you have a sash window, place the bracket on the window sill, extend the bracket fully within the window frame and lower the window onto the bracket. Insert the nozzle of the exhaust hose into the slot, then connect the hose to the air conditioner (Fig. 7). Thanks to the wing nut, it's possible to use the window bracket also for sliding windows. Position the hole of the bracket so to allow a correct installation of the exhaust hose.

Figure 6: Illustration showing suction discs used to secure a window or door closed.

Figure 7: Diagram illustrating the use of an adjustable window bracket for a sash window, with the exhaust hose nozzle inserted.

Preparing the Unit for Use

1. Fit the exhaust tube in place; if your conditioner is supplied with a bayonet tube, it is fitted as illustrated in the diagram.
2. For permanent installation, place the appliance near the wall or window outlet. Make sure it is standing on a level surface and fit the special shock absorbers/castor stops underneath the castors.

Figure 8: Diagrams showing how to fit the exhaust tube and prepare the unit for use, including fitting castor stops.

Electrical Connection

Check that the power supply voltage is 115 V ~ 60 Hz.

Important: If you need to use an extension cord, please be sure to use a heavy duty extension cord (minimum 14 gauge).

Before connecting the Pinguino to power supply, make sure that all switches on the front control panel are in the OFF position.

Connect power cord found in storage compartment at rear of the Pinguino (Fig. 9).

Figure 9: Illustration showing the power cord connection.

Final Check

In order to obtain the maximum performance from your air-conditioner, make sure that:

• Doors and windows of the room to be air-conditioned are closed (with the exception of temporary installation where a partially opened window is necessary). (Figure 10, 11)
• Shade the room as far as possible from direct sunlight by drawing curtains and/or lowering blinds or shutters, for economical and efficient air-cooling. (Figure 12)
• Ensure that intake and outlet vents (Fig. 2 and 3) are not blocked. (Figure 13)
• Make sure there are no sources of heat in the room.

Special Note

This machine is designed to be used with or without water. Maximum performance is obtained using water. When used without water, Pinguino will maintain a full 88% of its cooling capacity.

How to Prepare Water Container

Use only clean, salt-free tap water. The water is essential for the air cooling operation and is discharged in the form of steam through the exhaust outlet. A container full of water lasts for a period that depends on a number of conditions such as temperature, humidity, insulation, exposure of the room, number of people present, etc. On average, it will last approximately 7 to 10 hours.

When the container is empty, the appliance automatically changes function from water to air. At the same time, the quantity of air discharged from the rear hose will increase.

Figure 14: Diagrams showing the steps to prepare the water container: opening the compartment door, tipping and lifting the container to remove, removing the cap, pulling out the extendable tube, filling the container, replacing the tube, screwing the cap on tightly, and returning the container to its place with the word FRONT facing out.

During “water condensation” cooling function and in particularly quiet surroundings (e.g., bedroom), a slight gurgling noise may be heard. This may be regarded as perfectly normal.

Warning: Do not use water containing salt, e.g. seawater or water treated using softening systems that utilize kitchen salt.

Description of Pinguino PAC 290U Controls

Diagram of the Pinguino PAC 290U controls: Shows ON/OFF pilot light, ON/OFF button, Thermostat, "Alarm" pilot light, Timer, Timer ON/OFF pilot light, Timer ON/OFF button, and Selecting fan speed button.

Setting the Timer

The programmer/timer, like all clocks, must be set to the exact time. If for example it is 4:00 p.m., turn the dial in a clockwise direction (following the direction of the arrow) until the number 4 is lined up with the arrow pointer (the arrows indicate 4:00 p.m. approximately).

Note: Never turn the dial in an anti-clockwise direction!

The timer is, in effect, an electric clock and works only if the plug is connected to the power supply. Whenever the plug is disconnected or there is a power failure, the programmer stops (the clock is then “slow”) and must be re-set.

The unit can be used in either programmed or non-programmed mode.

Programmed Mode

1. Release B timer button.
2. Set the operating times by pushing out the notches on the dial corresponding to the period required (each notch represents 15 mins.).
3. Check that the timer indicates the correct time (see instructions on setting).
4. Select the desired function as shown in the chart overleaf. The unit will now switch on and off each day at the selected times.

Note: To override the programmed operating times, simply press the ON/OFF key.

Non-Programmed Mode

1. B TIMER button must be pressed.
2. Select the desired function as shown in the chart on the following page.

N.B: For technical reasons, the temperature is not expressed in degrees but by a line increasing in thickness. We therefore recommend that when starting up the appliance, the thermostat be turned to maximum (thick green line = maximum cold). When the desired temperature has been reached, turn the thermostat slowly away from the maximum cooling position until the appliance switches off. Leave the thermostat in this position. The air-conditioner is now programmed to maintain the exact temperature at all times.

After switching the appliance off, wait at least 3 min. before switching on again.

How to Start Up the Conditioner

(See control panel on the previous page)

1. Plug the appliance into the wall socket.
2. Select the “programmed” or “non programmed” mode (see previous page).
3. Select the fan speed required pressing “Fan speed” key C.

Air-Conditioning

• Key A ON/OFF (conditioning) must be released.
• Turn the thermostat to Max. Cold.
• Press key A (ON/OFF).
• ON/OFF signal lamp (conditioning) will come on.

The appliance comes on. If not, refer to pag. 14.

To switch off the appliance, press key A (ON/OFF main switch).
