The Ariston DEOS 12 is a dehumidifier designed for domestic use, aimed at improving indoor air quality by reducing humidity levels. This user manual provides comprehensive information on its safe operation, technical specifications, usage, and maintenance.
Function Description
The primary function of the DEOS 12 is to remove excess moisture from the air, thereby preventing the growth of mold, mildew, and bacteria, and creating a more comfortable and healthier indoor environment. It operates by drawing in humid air, passing it over a cooling coil where moisture condenses, and then discharging drier air back into the room. The condensed water is collected in a removable tank or can be continuously drained.
The dehumidifier features a control panel with indicator lights for various operating modes and settings. These include:
- Bucket Full Indicator Light: Illuminates when the water collection tank is full, signaling the need for emptying.
- Auto Defrost Indicator Light: Indicates that the appliance is in defrost mode, which is necessary to prevent ice buildup on the evaporator coils in cooler conditions.
- Continuous Operation Indicator Light: When lit, the appliance operates at maximum dehumidification level until the tank fills up. This mode is suitable for rapid dehumidification.
- Humidity Level Settings (40%, 50%, 60%): Allows the user to select the desired relative humidity level for the room. The appliance will operate until this level is reached and then maintain it.
- Humidity Level Set Mode Operation on Indicator Light: Confirms the selected humidity level.
- On/Off Indicator Light: Shows whether the dehumidifier is powered on or off.
The DEOS 12 also incorporates an Anti-frost function to prevent the evaporator from frosting, thereby extending the dehumidifier's life and enhancing energy saving. This function automatically activates when the ambient temperature is low. Furthermore, a compressor protection feature ensures that the compressor stops for at least 3 minutes before it restarts, preventing damage from rapid cycling.
Important Technical Specifications
The DEOS 12 is a robust dehumidifier with the following key technical specifications:
- Dehumidification Capacity: 12 litres per day, indicating its ability to remove up to 12 litres of moisture from the air over a 24-hour period.
- Power Consumption: 250 W (maximum), reflecting its energy usage during operation.
- Sound Pressure: 46 dB(A), indicating a moderate noise level during operation, which is typical for dehumidifiers of this capacity.
- Refrigerant Type: R290, a hydrocarbon refrigerant known for its low global warming potential (GWP) compared to traditional HFC refrigerants.
- Refrigerant Charge: 0.05 kg (50 grams).
- Operating Temperature: 5/32 °C, defining the ambient temperature range within which the appliance can operate effectively.
- Tank Capacity: 2.1 litres, specifying the volume of water the collection tank can hold before needing to be emptied.
- Power Supply: 230 V - 50 Hz, standard for UK domestic appliances.
- Type of Compressor: Reciprocating, a common type of compressor used in refrigeration and dehumidification systems.
- Maximum Air Flow Rate: 118 m³/h, indicating the volume of air the appliance can process per hour.
- Dimensions (W x D x H): 360 x 253 x 440 mm, providing the physical size of the unit.
- Weight (net/gross): 11.6 / 12.1 kg, indicating the appliance's weight.
The use of R290 refrigerant highlights the manufacturer's commitment to eco-friendly practices, as it has a significantly lower impact on global warming compared to older refrigerants. However, it also necessitates specific safety precautions due to its flammability.
Usage Features
The DEOS 12 offers several features to enhance user convenience and operational flexibility:
- Portable Design: Equipped with wheels, allowing for easy movement between rooms.
- Water Collection Tank: A removable tank for collecting condensed water. The appliance automatically stops when the tank is full to prevent overflow.
- Continuous Drainage Option: For extended operation without manual emptying, the dehumidifier can be connected to an external drain hose, allowing water to continuously flow out. This is particularly useful in basements or other areas where constant dehumidification is required.
- User-Friendly Control Panel: Intuitive buttons and indicator lights make it easy to select desired humidity levels, operating modes, and monitor the appliance's status.
- Safety Features: Includes warnings against placing objects on top of the appliance, covering air inlets/outlets, and operating near flammable materials. It also advises against using extension cords or adapters that are not specifically designed for the appliance.
- Optimal Placement: For best performance, the dehumidifier should be placed in a stable, smooth, and horizontal surface, away from walls and furniture to ensure proper air circulation. It should not be placed in areas where corrosive vapours or dangerous substances are present.
Maintenance Features
Regular maintenance is crucial for the longevity and efficient operation of the DEOS 12. The manual outlines several key maintenance tasks:
- Cleaning the Dehumidifier: The exterior of the appliance should be cleaned regularly with a cloth dampened in lukewarm water (no more than 40°C) and neutral soap. Abrasive cleaners, solvents, or aggressive detergents should be avoided.
- Cleaning the Tank: The condensate collection tank should be cleaned regularly (every 2-3 weeks) to prevent mold and bacteria buildup. Non-aggressive detergents should be used.
- Cleaning the Filter: The air filter should be cleaned regularly (at least every 30 days) to ensure optimal dehumidifier performance. This involves removing the rear grille, taking out the filter, washing it with lukewarm water and neutral detergent, drying it thoroughly (not in direct sunlight), and then putting it back.
- End-of-Season Maintenance: Before storing the dehumidifier for an extended period, the water present in the tank should be removed, the appliance and filter cleaned, and the appliance covered to protect it against dust. It should then be stored in a dry and well-ventilated place.
- Professional Servicing: For any malfunctions, repairs, or refrigerant-related issues, it is strongly recommended to contact qualified technical assistance or the manufacturer's customer service. The manual explicitly warns against attempting repairs or modifications by unqualified personnel, especially concerning the refrigerant circuit.
- Leak Detection Methods: The manual details methods for detecting refrigerant leaks, including using electronic leak detectors, soap bubble tests, and visual inspection for oil traces. If a leak is suspected, the appliance should be shut off, unplugged, and the area ventilated.
- Refrigerant Recovery and Labeling: Specific instructions are provided for the recovery of refrigerant by qualified personnel, emphasizing the importance of using appropriate recovery equipment and labeling cylinders correctly. This ensures safe handling and disposal of refrigerants in compliance with environmental regulations.
The DEOS 12 is designed to be a reliable and effective solution for managing indoor humidity, with clear guidelines for safe operation and maintenance to ensure its optimal performance and longevity.
