Function Keys:

• 1. On/OFF: Switches the dehumidifier on and off. In off mode, energy consumption is 0.5 W.
• 2. Setting of the desired humidity: Active only in "Normal" and "Fan" modes. Humidity can be set between 35-75% in 1% increments. The set value is displayed fixed, then flashing, before the actual value reappears.
• 3. Mode selection: Selects the operating program (refer to points 13-16 below).
• 4. Fan speed: In "Normal" and "Fan" modes, fan speed can be set to low or high. Switching between speeds takes a few seconds.

Alarms / Information

• 5. Defrost: If necessary, the cooling circuit is automatically defrosted. The compressor switches off, and only the fan operates. The symbol turns off when the dehumidification process restarts.
• 6. Too high ambient temperature: If the ambient temperature exceeds 35°C, the dehumidification process shuts off and resumes automatically when the temperature falls below 35°C. The symbol is lit when the temperature is 35°C or higher.
• 7. Low room temperature: If the ambient temperature falls below 2°C, the dehumidification process shuts off and resumes automatically when the temperature rises above 2°C. The symbol is lit when the temperature is 2°C or lower.
• 8. Condensate tank full: An audible signal sounds for 20 seconds, and the symbol lights up when the tank is full. After emptying and repositioning the tank, the operating program resets automatically. Ensure the float hangs freely in the tank.
• 9. Room temperature: Displays the detected ambient temperature.
• 10. Fan speed: Fan and dashes indicate high speed; Fan only indicates low speed.
• 11. Relative humidity: Shows current and desired target values.
• 12. WiFi: Indicates when WiFi is connected (applies only to models equipped with this feature).

Operating Modes

• 13. Fan mode: Used for continuous air circulation. Fan speed and target humidity can be set. When the target value is reached, only the compressor switches off and restarts if humidity rises.
• 14. Comfort mode (EASY): Aims for 50% relative humidity with low fan speed. When the target value is reached, compressor and fan shut off and restart if humidity rises above 50%. The compressor remains off for at least 5 minutes after shutdown to allow the cooling system pressure to equalize.
• 15. Laundry drying mode (LAUNDRY): Dehumidification operates at high fan speed until manually turned off or the mode is changed.
• 16. Normal Mode (NORMAL): Used to manually set the target humidity and fan speed. When the target value is reached, compressor and fan shut off and restart if humidity rises above the target value. The compressor remains off for at least 5 minutes after shutdown to allow the cooling system pressure to equalize.
• 17. Lock function: Prevents unintentional setting changes. Activated by pressing FAN and MODE keys simultaneously for 3 seconds. Disabled the same way.

Using Wood's Dehumidifiers

Wood's: The World's Leading Dehumidifiers

Wood's dehumidifier products are recognized market leaders, designed for demanding climates with effective dehumidification even at lower temperatures and humidity levels. They are suitable for damp premises like basements, garages, and summer houses, and are also effective for drying laundry, in pool areas, and laundry rooms. They are efficient and consume low energy.

The amount of moisture removed depends on temperature, humidity, and placement. Outdoor weather also affects performance; colder weather reduces indoor relative humidity, thus decreasing moisture absorption. The dehumidifier is adapted for temperatures between +2°C and +35°C. Wood's dehumidifiers are safe and designed for continuous operation over many years.

Excessive Air Humidity - A Danger

Condensation occurs when water vapor contacts a cold surface, forming water droplets. High humidity can lead to stale air, mold growth, damage to the house and its interior, and health issues for inhabitants (e.g., mites). A high-performance dehumidifier creates a healthy moisture level. For best results, keep doors and windows closed in the area being dehumidified. The dehumidifier removes odors, dries wood, and moisture from sports equipment.

Dehumidifiers can be used in basements, laundry rooms, garages, caravans, summer cottages, and boats. For use in colder environments, consult the hints section.

Important: If placed in a shower or bathing area, the dehumidifier must be fixed in place. Local bathroom electrical regulations must be checked and followed before use.

Using Wood's Dehumidifiers

If transported horizontally, leave the dehumidifier standing upright for 4 hours before use to allow oil to return to the compressor, preventing serious damage. Wood's dehumidifiers are easy to move due to wheels. Ensure proximity to a 220-240V electrical outlet, keeping the following in mind:

• Do not place near radiators or heat sources, or in direct sunlight, as this reduces performance.
• A radiator or heating fan can be used to keep the temperature above +2°C.
• Place the dehumidifier at least 25 cm away from walls and obstructions for maximum airflow.
• Ideally, place the dehumidifier centrally in the room or area.

1. Check that the water tank is correctly positioned.
2. Connect the dehumidifier to a grounded electrical outlet.
3. Select the desired humidity program or level using the control panel (refer to Function Description).

Note: When the dehumidifier switches off, it takes 5 minutes before it restarts.

Float

The float is a white plastic cylinder suspended by wires. It rises with the water level. When it reaches a certain height, the dehumidifier detects it and automatically shuts off to prevent flooding. To re-insert the float after emptying the tank:

Emptying Water Containers

1. When the tank is full, gently pull it outwards and empty it into a drain.
2. Push the water container back in until it touches the float.
3. Lift the bottom edge of the water tank slightly to incline it.
4. Push the water tank in the final distance. The float should now be inside the water tank, not clamped behind it.

Note: It is important that the float hangs freely to correctly detect the water level and ensure the dehumidifier shuts off. An incorrectly positioned float can cause the tank to overflow.

Drain the Water to the Sewer

1. Disconnect the dehumidifier from the electrical outlet and remove the water tank to access the threaded connection under the drip tray.
2. Attach the hose coupling to the threaded connector and run the hose to the drain. Ensure the hose is positioned lower than the drip tray.
3. Insert the dehumidifier plug into the socket.

Without hose and directly over the drain: Place the dehumidifier directly over the drain so condensed water drips through the bottom hole into the drain.

Automatic Shutdown

When the water tank is full, the dehumidifier shuts off automatically, indicating the tank needs emptying. Refer to the function description.

1. Disconnect the dehumidifier from the electrical outlet.
2. Empty the water tank.
3. Replace the emptied tank, ensuring the float hangs free (see Float section).
4. Connect the dehumidifier to the electrical outlet. It will restart in the same mode as when disconnected.

Air Filter

The air filter on the back prevents dust from reaching the cooling coils, ensuring efficient airflow. The filter should be replaced when needed. The dehumidifier uses an SMF filter that improves capacity and purifies air. Refer to instructions for changing the air filter. Replacement at least once a year is recommended. Register your dehumidifier at warranty-woods.com for the warranty program.

Automatic Defrost

Wood's dehumidifiers have a control system that defrosts cooling coils when necessary. The compressor switches off, stopping cooling, while the fan draws room air through the unit to melt ice. Water flows into the tank. This system allows operation at temperatures as low as +2°C.

Fan

The fan ensures airflow through the dehumidifier. Moist air is drawn in from the back, passes through the evaporator and condenser, and is released dry from the top.

Cleaning and Maintenance

Regular cleaning and filter replacement are essential for maintaining high dehumidification capacity.

• The air outlet can be vacuumed or cleaned with a brush. Use caution to avoid damaging the slats.
• Cooling coils are best cleaned with a cloth and warm water. Use caution.
• The fan motor is permanently lubricated and requires no maintenance.

Note: Unplug the power cord from the electrical outlet before cleaning.

Hints

• For maximum dehumidification, minimize air supply from outside and adjoining rooms by closing doors and vents. Place the dehumidifier in the middle of the room if possible.
• Raise room temperature for faster dehumidification (hot air carries more water). Use a frost guard if the temperature drops below +2°C.
• The dehumidifier extracts more water in summer and autumn due to warmer, moister outdoor air.
• Recommended limits for use:
• Temperature: +2°C to +35°C
• Relative humidity: 30% to 90%
• Recommended moisture level: approx. 50% RH
