USER MANUAL DES 12 DELONGHI

Air always contains a certain amount of water in the form of vapour. This determines the level of humidity in an atmosphere.

The capacity of the air to hold water vapour increases with 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, avoiding the damage caused by condensation.

DESCRIPTION/ACCESSORIES

1. Control panel
2. Water level viewing window
3. Condensate collection tank

Experts have established that the optimum environmental conditions for our well being and for the home are obtained between 40% and 60% relative humidity. With very low temperatures, you are recommended to heat the room even minimally.

This considerably increases the dehumidifying power of the appliance.

With heating, the condensation formed by the water vapour on windows and other cold surfaces evaporates into the air to be collected by the dehumidifier. Air leaving the dehumidifier is usually about 1°C warmer than room temperature.

As a reminder of the need to dispose of household appliances separately, the product is marked with a crossed-out wheeled dustbin.

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 dehumidifier, so as not to block the air outlet.

For efficient ventilation a space of about 5-10 cm should be left at the back of the appliance.

The condensate can be drained in one of the following ways:

A) Draining into the tank

The condensate can be drained directly into the tank. The tank can be easily removed (fig.1).

B) Continuous external draining

If the appliance is to be operated for long periods but you are unable to empty the tank regularly, you are recommended to use the continuous drain facility.

1) Remove the continuous drain cap by turning it anticlockwise then remove the rubber bung from the spout (fig. 2). 2) Fasten the rubber hose to the spout.

3) Make sure the end of the hose is no higher than the spout or water could remain in the tank. Make sure there are no kinks in the hose (fig. 3).

Please Note: Keep the rubber bung to close out.

Instructions for fitting the castors

1) Unplug from the mains socket and empty the tank (if full). 2) Remove the rubber caps from the bottom of the appliance by pulling forcefully or using pliers (see figure 4/1). 3) Fit the castors by inserting the pins into the holes. (see figure 4/2)

HOW TO DEHUMIDIFY

How to dehumidify

• Plug the appliance into a mains socket.
• Make sure the "tank full/tank missing" light is off. If it is on, position the tank correctly.
• The dehumidifying standby light comes on during the first three minutes (safety device), then the appliance starts dehumidifying.
• The humidistat dial is used to adjust the humidity level as desired (MIN/MED/MAX and intermediate levels).

When the dial is on MIN, the dehumidifier removes only a small amount of humidity from the room. On MAX, it removes a large amount of humidity.

To dehumidify, adjust the humidistat to one of the positions available.

Dry mode (drying washing)

To remove a large amount of moisture (for example when drying washing), you are recommended to operate the appliance at maximum power by turning the humidistat dial to DRY.

In this mode, the dehumidifier operates continuously, irrespective of the level of humidity in the room.

INDICATOR LIGHTS

Tank control system light

This dehumidifier has a special device to control 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: reposition the tank
3. the tank is incorrectly positioned: position the tank correctly
4. with continuous drain: the hose is blocked or sloping upwards (water is still draining into the tank) remove the obstruction

When the cause has been removed, the light goes off and the appliance resumes operation.

Dehumidifying standby/low-temperature operation light

PAUSE

The light comes on:

1) To indicate the appliance is in standby for about three minutes before start-up. This device protects the compressor from starting and stopping too often. 2) To indicate low temperature operation. When the temperature in the room is too low, the low temperature operation electronic device trips. This operates the appliance with alternate cycles of dehumidifying and fan only to avoid the formation of ice.

For frequent use in particularly cold rooms, you are recommended to raise room temperature, even if only slightly.

This ensures that the dehumidifier is operating under suitable conditions, improving its performance and accelerating dehumidification.

CLEANING AND MAINTENANCE

Always unplug the appliance from the power socket before performing any cleaning or maintenance operations.

For safety reasons, never wash the dehumidifier using a jet of water.

Cleaning the cabinet

- Clean the appliance using a damp cloth then dry with a dry cloth.

- Do not use petrol, alcohol or solvents to clean the appliance.

- Do not spray liquid insecticide or similar products as they may deform the plastic.

Cleaning the silver ion 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.

- Remove the air filter by pulling sideways (Fig. 5).

- Use a vacuum cleaner to remove dust accumulations from the filter.

If the filter is very dirty, rinse well in warm water.

The temperature of the water must not exceed 40°C.

After washing the filter, allow it to dry completely before repositioning it.

The silver ion filter not only retains dust

particles, but also has an efficient antibacterial action. It also greatly reduces concentrations of irritants such as pollen and spores.

The filter is treated with small particles of silver (on the scale of millionths of a millimetre) which are able to block the multiplication of and destroy any bacteria or spores coming into contact with them.

If the appliance is not used for long periods

• After unplugging the appliance from the power socket, empty the tank. - Clean and reposition the filter. - Cover the appliance with a plastic bag to protect it from dust.
