Frequently Asked Questions - Ariadry DDS 30 DELONGHI

How do I set the desired humidity level?

Press the +/- buttons on the control panel to adjust the humidity set point. The digital display shows the current setting. Typically, recommended humidity is between 50% and 60%.

Can I use a continuous drainage hose?

Yes, the DDS 30 has a continuous drainage outlet. Attach a standard garden hose (not included) to the connector at the back, and direct it to a floor drain or sink. Ensure the hose is not kinked.

How often should I clean the air filter?

Clean the washable air filter every two weeks of normal operation. A clogged filter reduces efficiency. Remove the filter, rinse with warm water, dry thoroughly, and reinstall.

What does the auto defrost function do?

When the ambient temperature is low, ice may form on the coils. The auto defrost function periodically stops the compressor to melt ice, then resumes operation automatically to maintain efficiency.

Why is the dehumidifier not collecting water?

Possible causes: the set humidity is not lower than room humidity, the filter is dirty, the room temperature is too low (<5°C), or the water tank is not properly positioned. Check these factors.

What is the maximum room size for this dehumidifier?

The Ariadry DDS 30 is suitable for rooms up to approximately 30 m² (320 sq ft) under normal humidity conditions. For larger spaces or high humidity, multiple units may be needed.

How do I empty the water tank?

When the tank is full, the unit beeps and shuts off. Pull out the tank from the front, carry it to a sink, remove the cover, and pour out the water. Replace the tank securely to resume operation.

Can the dehumidifier run continuously?

Yes, but the compressor cycle depends on humidity. If set to continuous mode (100% target humidity), the fan runs constantly and the compressor on/off as needed. Use only with continuous drainage.

What is the power cord length?

The power cord is approximately 1.8 meters long. Avoid using extension cords if possible, or use a heavy-duty one rated for the appliance's power.

Is the dehumidifier noisy?

Noise level is about 45 dB(A), which is moderate. Place the unit on a level surface away from walls for optimal performance. Do not place it in sleeping areas if sensitive to sound.

Some notions on humidity

Air always contains a certain quantity of water in the form of vapour; this determines the degree of humidity in a room.

The capacity of air to contain water vapour increases as its temperature increases.

This is why in our homes, as soon as the temperature drops, the air releases the water vapour contained in it, turning into condensation, which appears on all cold surfaces such as windows, walls etc.

The dehumidifier is an electric appliance that extracts humidity from the air, avoiding the damage that it causes.

Studies have established that the ideal conditions for our

health and home are achieved when relative humidity is between 40% and 60%.

With very low temperatures, you are recommended to heat the room even minimally. This will increase the dehumidifying capacity of the appliance considerably. This is the only way, in fact, to allow the condensation that forms on the windows and other cold surfaces to evaporate into the air and be collected by the dehumidifier.

The Extra Power mode included in this model makes it easier to raise the temperature. The air released by the dehumidifier is, however, generally warmer than the air in the room.

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 with a slightly damp cloth.
• Do not use petrol, alcohol or solvents to clean the appliance.
• Do not spray liquid insecticide or similar; they may deform the plastic.

Cleaning the air filter

If the filter is dirty, air circulation is compromised and consequently the efficiency of the dehumidifier decreases.

It is therefore good practice to clean the filter at regular intervals. Frequency depends on the conditions and duration of operation. If the appliance is used constantly or frequently, it is advisable to clean the filter once a week.

- Once the tank has been taken out, remove the filter by pulling it downwards (fig. 6).

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

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

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

After washing the filter, allow it to dry completely before putting it back in place. The filter, in addition to trapping dust particles, has an anti-bacterial action.

Furthermore, it considerably reduces other irritating agents such as pollen and spores.

For long periods of downtime

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