ILLUSTRATED ACCESSORY LIST

ACCESSORY CHECK

Check that all parts listed in Table 1 are included.

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.

Installation Methods

A1: In a window pane

Diagram shows a cross-section of a window pane with an exhaust vent adapter installed. The opening diameter is approximately 4.17 inches.

A2: Through the wooden base-section of a door or window

Diagram shows a cross-section of a wooden frame (door or window base) with an exhaust vent adapter installed. The opening diameter is approximately 4.17 inches.

A3: Through the wall

Diagram shows a cross-section of a wall with an exhaust vent adapter installed. The opening diameter is approximately 4.17 inches. A clearance of 1 inch is indicated for leaving a door ajar.

Note on Room Air-tightness: In case of fixed installation, air discharged from the rear hose is extracted from the room. 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.

1. Shows water collecting at a point (likely the drain).
2. Shows bending a section of the exhaust tube.
3. Shows bending another section of the exhaust tube.

Followed by "NO" and "YES" indicators, suggesting a confirmation or check.

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).

Fig. 9: Illustration of the power cord.

FINAL CHECK

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

• Doors and windows of room to be air-conditioned are closed (with the exception of temporary installation where a partially opened window is necessary). (Fig. 10, Fig. 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. (Fig. 12)
• Ensure that intake and outlet vents are not blocked. (Fig. 13)
• Make sure there are no sources of heat in the room.

SPECIAL NOTE ON WATER USAGE

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.

Water Container Preparation Steps (Fig. 14)

The diagram shows three steps:

1. Open the water container compartment door, tip the container forwards and lift up to remove.
2. Remove the cap, pull out the extendable tube and fill the container, standing it on the floor.
3. After filling, replace the extendable tube, screw the cap on tightly and return the container to its place, making sure the word FRONT is facing out.

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

Warning:

Do not use water containing salt, eg. seawater or water treated using softening systems that utilize kitchen salt.

DESCRIPTION OF PINGUINO PAC 290U CONTROLS

The control panel includes the following elements:

• Timer: A circular dial with numbers and an arrow pointer for setting time.
• ON/OFF pilot light: Indicates the unit's power status.
• ON/OFF button: Main power switch.
• Thermostat: A dial for setting the desired temperature.
• “Alarm” pilot light: Indicates a fault condition.
• Timer ON/OFF pilot light: Indicates timer status.
• Timer ON/OFF button: Button to activate/deactivate the timer.
• Selecting fan speed button: Button to choose fan speed.

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 indicates 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.

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.). Example: from 9 to 11 a.m.
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)

A flowchart illustrates the startup process:

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.
4. AIR-CONDITIONING: Key A ON/OFF (conditioning) must be released. Turn the thermostat to Max. Cold. Press key A (ON/OFF). The ON/OFF signal lamp (conditioning) will come on.
5. The appliance comes on. If not, refer to pag. 14.
6. To switch off the appliance, press key A (ON/OFF main switch).
