Frequently Asked Questions - GDDEK20 DIMPLEX

How often should I clean the humidifier?

Clean the water tank and base weekly using a mixture of water and white vinegar. Regular cleaning prevents mold and mineral buildup.

What type of water should I use?

Use distilled or demineralized water to reduce white dust. Tap water can be used but may cause mineral deposits.

How do I replace the filter?

Turn off and unplug the unit. Remove the water tank, open the filter compartment, and replace the old filter with a new Dimplex F20 filter. Reassemble.

Why is there no mist coming out?

Check the water level—tank may be empty. Ensure the unit is placed on a flat surface and the mist nozzle is not blocked. Clean if necessary.

Can I use essential oils in the humidifier?

No, this model is not designed for essential oils. Adding oils can damage the unit and void the warranty.

How do I adjust the humidity level?

Use the rotary dial to adjust mist output. Higher settings increase humidity; lower settings decrease it. There is no built-in hygrometer.

What does the auto shut-off feature do?

The humidifier automatically turns off when the water tank is empty, preventing damage and ensuring safety.

Why does the humidifier make a gurgling sound?

Air bubbles in the water tank cause gurgling. This is normal. Ensure the tank sits properly to minimize noise.

How long does the filter last?

Replace the filter every 3 months or sooner if you notice reduced output or odor. Use only genuine Dimplex filters.

What is the ideal room humidity?

Aim for 40-60% relative humidity. Higher levels may cause condensation on windows. Use a hygrometer to monitor.

The different levels are: continuous dehumidification, 40% relative humidity, 50%, relative humidity, 60% relative humidity or 70% relative humidity. The appropriate indicator light will turn on. The ideal room humidity is 50% to 70%

1. Press (ventilation speed button) to set the wind speed to high or low. The "HI" or "LO" indicator lights will show the speed.
2. Pre-setting timer function. You can programme the unit to turn on after a set amount of time. Without turning on the other functions (including ON/OFF button), press the "TIMER" button and select the number of hours until you want the dehumidifier to turn on. For example, if you press the timer to '2' (see "Humidity/ Temperature/Timer" display), the unit will automatically turn on after 2 hours.

For example, if you select "2" on the Timer display, the unit will turn off after 2 hours of operation. After 8 seconds the display will revert back to showing the current room humidity.
4. By pressing the "SHOW TEMPERATURE/HUMIDITY" button, the "Humidity/ Temperature/Timer" display will show the current room temperature. After 8 seconds, the display window will return to showing the room humidity.
5. The "DRYER" function provides turbo ventilation to rapidly and continuously dehumidify the moisture in the air – perfect for drying laundry indoors.
6. To turn off the unit, press the "ON/OFF" button

WHERE TO POSITION

When positioning the dehumidifier, ensure that it is placed on a level surface and that there is a minimum of 10cm (4") of space on either side of the unit to allow for efficient airflow.

This dehumidifier is fitted with castors for extra mobility, if you move the unit, it should first be switched off and the water tank emptied. We do not recommend the use of an extension lead, instead ensure that the unit is sufficiently close to a fixed mains socket.

When the dehumidifier is in operation, outside doors and windows should be closed when necessary for most efficient use.

PARTS

ACCESSORIES

HOW IT WORKS

Your dehumidifier controls relative humidity by passing air through the unit, forcing the excess moisture to condensate over the cooling elements. Contact with this cold surface causes the moisture in the air to condense. This condensed water then drains safely into the anti-bacterial water tank. The dried air then passes through the condenser where it is slightly warmed and re-enters the room.

DRAINAGE

When the water tank is full, the dehumidifier will stop and the "Full Water Tank" indicator will light up. To remove the water tank, carefully pull it out squarely from the unit.

After emptying the water tank, slide the water tank back into place. Make sure it is properly positioned, in order for the "Full Water Tank" indicator light to turn off and your dehumidifier to resume operation.

Please note, if the water tank is not positioned correctly the light will stay red and operation will cease.

Continuous drainage

In situations where the water tank will require more frequent drainage (for example when humidity is high), it may be more convenient to set the unit up for continuous drainage.

1. Pull out the water tank.

2. Connect the drain hole with a drainage hose of 11mm internal diameter. Please note, this drainage hose is not supplied with the unit.

3. Ensure the water drains away freely and the tube is secure. In very cold weather conditions, precautions should be taken to prevent the drainage hose from freezing.

4. Put the water tank back to its position.

MAINTENANCE

Always unplug the unit from the mains before carrying out any maintenance or cleaning of the unit.

CLEANING THE BODY

Use a soft cloth to wipe the unit clean.

Do not use volatile chemicals, gasoline, harsh detergents, or abrasive cleaning solutions, as these may damage the external body of the unit

CLEANING THE FILTER

This dehumidifier is equipped with 2 filters :

graph LR
    A["washable plastic filter"] --> B["active carbon filter"]
    B --> C["Commercial air conditioner unit"]

1. WASHABLE PLASTIC FILTER

• Remove the washable plastic filter and take off the active carbon filter.
• Use a vacuum cleaner to remove dust caught in the washable plastic filter or tap the filter lightly to dislodge any other particles. If the filter is particularly dirty, use warm soapy water to clean it.
• Make sure the filter is completely dry before replacing.
• Do not expose the filter to sunlight.

2. ACTIVE CARBON FILTER (for capturing fine particles, bacteria prevention and certain toxic chemicals from the air and moisture in your room.)

The active carbon filter, located under the anti-dust filter is not washable.

The filter should be checked periodically and replaced if necessary (around once per season).

STORAGE

If unit is not to be used for an extended period of time store by

• Turning the unit off, unplugging and tidily storing the cord.
• Completely emptying the water tank and wiping it clean.
  • Covering the unit and storing away from direct sunlight
