What are the Pinguino portable air conditioners?
uring the summer, you feel comfortable at a temperature of between 75 and 81F (24 and 27C) with a relative humidity of about 50%. An air conditioning unit removes excess moisture and heat from the room where it is located. Compared with installed models, portable air conditioning units 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 (Pinguino), a small part of this air is used to cool the refrigerant gas and then, when hot and damp, is discharged outside.
Installing your por table air-conditioner
ELECTRICAL CONNECTIONS Before plugging the appliance into the electrical socket, check that: the power supply corresponds to the value indicated on the rating plate on the back of the appliance; the socket and electrical circuit are adequate for the appliance; the socket matches the plug. If this is not the case, have the plug replaced; the socket is adequately grounded. Failure to follow these important safety instructions absolves the manufacturer of all liability. The power cord must be replaced by a qualified professional only.
The instructions below will enable you to prepare your air conditioning unit for operation as efficiently as possible. Before use, make sure the air intake and outlet grilles are unobstructed.

In case of fixed installation, air discharged from 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 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 window or door closed (Fig. 6).
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, its 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 (see the following instructions).

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

Check that the power supply voltage is 115 V ~ 60 Hz. Important: if you need to use and 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).

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

fig. 10

Doors and windows of room to be airconditioned are closed (with the exception of temporary installation where a partially opened window is necessary).

fig. 11

fig. 12

fig. 13

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.
Ensure that intake and outlet vents (fig. 2 and 3) are not blocked. 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 si 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.

fig. 14 Open the water container compartment door, tip the container forwards and lift up to remove. Remove the cap, pull out the extendable tube and fill the container, standing it on the floor. 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.

arrow pointer
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. 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.
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.
