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.

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, 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 (see
the following instructions).

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.

NO YES YES
ELECTRICAL CONNECTION
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).

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

- Doors and windows of room to be air-
conditioned are closed (with the
exception of temporary installation where
a partially opened window is necessary).
- 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.
FINAL CHECK
In order to obtain the maximum performance from your air-conditioner make sure that:
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.

DESCRIPTION OF PINGUINO PAC 290U CONTROLS
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.
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.

Operating time
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.

AIR FILTER CLEANING
Maintenance of air filter
A clogged air filter reduces the quantity of
circulating air and the efficiency of the
appliance. Clean filter every week using a
vacuum cleaner.
Removal and replacement of air filter
Gently pull filter upwards.
Push down to replace.
Cleaning procedure
To remove dust deposited on filter, use a vacuum cleaner. If it is very dirty, soak in lukewarm water
and rinse thoroughly. The temperature of the water must be kept below 104°F. After washing, leave
filter to dry before replacing.
END OF SEASON OPERATIONS
