DeLonghi DEC12-14 User manual

Air always contains a certain amount of water in the air in the form of water vapour.
This amount of moisture is commonly known as the humidity.
The capacity of the air to hold water vapour increases with the temperature. This is why in our
homes, as soon as the temperature decreases, the vapour contained in the air condenses, as
is evident on the colder surfaces in the room, such as the windows, walls etc.
The purpose of a dehumidifier is to remove the excess moisture from the air, to control con-
densation within the home.
Experts have established that the optimum environmental conditions for our well being and
preserve objects are obtained between 40% and 60% relative humidity. Below these levels the
air can feel too dry and may cause skin complaints and even static electric shocks.
If temperatures in the home are lower than 10°C for prolonged periods low level heating will
be necessary to allow the condensate to evaporate into the air before dehumidification can
take place. The air will however be slightly warmed by the dehumidifier as the dry air leaving
the dehumidifier is about 1°C higher than normal room temperature.

Instructions for fitting the wheels
1) Make sure the appliance is unplugged from the mains and the tank is empty
2) Remove the rubber caps from the base of the appliance by pulling them out, using pliers if
necessary (see Figure 1/1).
3) Fit the wheels by inserting the shafts into the holes (see Figure 1/2)
Note: When performing these operations, make sure the appliance is not tilted over 45°; in any
case, after fitting the wheels, wait at least one hour before using the appliance again.
Installation
Position the appliance in the room to be dehumidified:
A free space of at least 50 cm must be left at the front of the humidifier, so as not to block the
air outlet. A space of around 5-10 cm should be left at the rear of the appliance for aeration.
Condensate can be drained in one of two ways:
A) Draining into the tank
The condensate can be drained directly into the tank located inside the appliance (fig. 2).
The tank can be easily removed and has a handle making it simple to carry and empty.
B) Continuous external draining
If the appliance is to be operated for long periods of time but you are unable to empty the tank,
you are recommended to use the continuous drain facility.
1) Drill the inside of the drain spout using a 7 mm dia. drill bit or removing the precut section
by pressing with a screwdriver or similar (Fig. 3).
2) Fasten the rubber hose to the spout. For models without drain hoses supplied, we sug-
gest you purchase a rubber hose around 1 m long, with an internal diameter of 9.5 mm.
3) The condensate drain hose must under no circumstances slope upwards, otherwise the
water may remain in the tank. Check there are no kinks in the hose (Fig. 4).
.
N.B.: Keep the rubber bung. You will need it to plug the hose or close the spout if you
revert to draining into the tank (see point A).

How to dehumidify (Models with humidistat)
1) Plug the appliance into a mains socket.
2) Check that the “tank full/tank missing” light is off; if not, place the tank to the correct
position.
3) The dehumidification standby light switches on in the first 3 minutes (safety device), after
which the appliance starts dehumidifying.
4) The humidistat knob is used to adjust the humidity level as desired (MIN/MED/MAX). When the
knob is on MIN, the dehumidifier will slightly lower the humidity in the room; on MAX, on the other
hand, the appliance will considerably lower the humidity in the room. To dehumidify simply
turn the humidistat to one of the positions available.
How to dehumidify (Models with humidistat and function knob)
1) Plug the appliance into a mains socket.
2) ) Check that the “tank full/tank missing” light is off.
3) Select the or or the dehumidification standby light switches on in the
first 3 minutes (safety device), after which the dehumidification light switches on. The
mode is only used to purify the air, without dehumidifying.
4) The humidistat knob is used to adjust the humidity level as desired (MIN/MED/MAX). When the
knob is on MIN, the dehumidifier will slightly lower the humidity in the room; on MAX, on the other
hand, the appliance will considerably lower the humidity in the room. Then turn the humidistat
to one of the positions available.

Dehumidifier functions
Your appliance features 4 functions: air purification , low consumption dehumidification
, comfort function , clothes drying .
Turn the function knob anticlockwise to select the various functions, as desired.
Purification function
Ideal where dehumidifying is not required, but simply to filter the air using the electrostatic fil-
ter supplied. The appliance will operate at low fan speed. The filter also purifies in all the other
dehumidification functions.
Low consumption dehumidification function
When the set humidity level in the room is reached, the appliance stops.In cases where dehu-
midifying is required, while reducing consumption and limiting noise.
Comfort function
This is the function used to reach the desired comfort level (set on the humidistat) in the faste-
st time possible.
Dry function (clothes drying)
Recommended when operating the appliance at maximum capacity, to remove large quan-
tities of moisture (e.g. for drying clothes). In this mode the dehumidifier works independently of
the humidistat.

How to dehumidify
Tank control system
This dehumidifier is fitted with a special device to ensure correct operation.
A red indicator light on the control panel comes on to warn the user when:
1. the tank is full . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .empty the tank
2. the tank is missing . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .replace the tank
3. the tank is in the wrong position . . . . . . . . . . . . . . . . . . .position the tank correctly
4. in continuous drain: the hose is obstructed or the difference in level is
too great . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .remove the obstruction.
Once the cause has been eliminated, the light goes out and the appliance resumes operation.
Dehumidification light (some models only)
This switches on when the machine is dehumidifying. The light remains on only when the
appliance is effectively dehumidifying; if the humidity in the room is already low enough, the
light will be off.
Dehumidification standby/low temperature operation light
The light switches on in the following two cases:
1) To signal a delay of around 3 minutes in the start-up of the appliance. This device protects
the compressor against too frequent starts and stops.
2) To signal low temperature operation. When the room temperature is too low, the electronic
low temperature operation device is activated. The device makes the appliance operate
by alternating dehumidification cycles and fan only cycles, thus avoiding the formation of
frost. For frequent use in cold environments, it is recommended to heat the room at the
same time, even slightly. This allows the dehumidifier to operate in conditions that ensure
better performance and faster dehumidification.

Cleaning/Warnings
Maintenance
Always remove the plug from the power socket before performing any cleaning or mainte-
nance operations. For safety reasons, never wash the dehumidifier using a water jet.
Cleaning the cabinet
• Clean the appliance using a damp cloth then dry with a dry cloth.
• Never use petrol, alcohol or solvents to clean the appliance.
• Never spray the appliance with insecticides or similar. These could cause the paint to flake or
plastic parts to warp.
Cleaning the air filter
If the filter is dirty, air circulation is compromised and the efficiency
of the dehumidifying and air purifying functions decreases.
It is therefore good practice to clean the filter at regular intervals.
The frequency depends on the duration and conditions of operation.
If the unit is used constantly or systematically, you are
recommended to clean the filter once a week.
•To remove the air filter, extract by pulling it as shown in fig. 5.
•Use a vacuum cleaner to remove dust accumulations from
the filter. If the filter is very dirty, wash in warm water and rinse
several times. The temperature of the water should not
exceed 40˚C. After washing the filter, allow to dry completely
If the appliance is not used for long periods
•Unplug from the mains socket and empty the tank.
•Clean and reposition the filter.
•Cover the appliance so that dust does not build up.
Electrostatic purification filters (some models only)
The special high-efficiency electrostatic filter can capture very small particles (down to 0.3
µm). The filter is active in all of the functions.
Replace the filter at the end of each season, or in any case when depleted. The filters are avai-
lable at the authorized DL service centres or Dè Longhi sales outlets.
Do not attempt to clean the electrostatic filter, as this may diminish its filtering capacity
