Frequently Asked Questions - GDDEYS40A DIMPLEX

How do I set the desired humidity level on my Dimplex GDDEYS40A dehumidifier?

Press the Humidity Set button on the control panel. Use the + and - buttons to adjust between 35% and 85%. The digital display will show your selected humidity.

What does the 'Full Tank' indicator mean and how do I empty the water tank?

The Full Tank indicator lights up when the tank is full. To empty, carefully slide out the tank from the front of the unit, remove the lid, pour out the water, replace the lid, and slide the tank back in until it clicks.

Can I use a continuous drain hose with this dehumidifier?

Yes. Remove the drain plug from the back of the unit, connect a standard garden hose (3/4 inch thread) to the drain outlet, and route the hose to a floor drain or sink. Ensure the hose is not kinked.

How often should I clean the filter?

Clean the washable mesh filter every 2 weeks or when the Filter Clean indicator appears. Remove the filter, rinse it with warm water, let it dry completely, and reinstall.

The dehumidifier is not collecting water. What could be wrong?

Check that the humidity setting is lower than the current room humidity. Ensure the filter is clean, the room temperature is above 41°F (5°C), and the unit is placed away from walls and obstructions.

Can I operate the dehumidifier in a cold room or basement?

The unit is designed to operate in temperatures from 41°F to 95°F (5°C to 35°C). In colder conditions, the compressor may cycle less frequently or ice may form on coils. It is not recommended for freezing temperatures.

How do I set the timer to turn the dehumidifier off automatically?

Press the Timer button repeatedly to select 1 to 24 hours. The display will show the set hours. The unit will run for that duration then automatically shut off.

What does the 'Auto Defrost' function do?

If frost builds up on the coils, the Auto Defrost feature automatically shuts off the compressor but keeps the fan running to melt the frost. Once defrosted, normal operation resumes.

Why is my dehumidifier making unusual noises?

Common noises include: a gurgling sound from refrigerant flow (normal), clicking when the compressor starts, or a vibrating sound. Ensure the unit is on a level floor and not touching walls. If noise persists, check for loose parts.

How do I reset the filter cleaning indicator?

After cleaning and reinstalling the filter, press and hold the Filter Reset button (or the Timer button for 3 seconds, depending on model) until the indicator light turns off.

DEHUMIDIFICATION INSTRUCTIONS

Automatic dehumidification

Under this mode, the dehumidifer will dehumidify the room according to the humidity setting you have chosen (press "HUMIDITY LEVEL" to adjust). The ideal humidity for a room is between 50%-60%. The dehumidifier will only operate if the room humidity is higher than what you have set.

Continuous dehumidification

Under this mode, the dehumidifier will continuously dehumidify the room, regardless of the room's humidity. This function is particularly useful if you are trying to dry up a wet area.

When humidity is low, the dehumidifier fan will operate on a low speed, dehumidifying slower. When humidity is high, the dehumidifier fan will operate on a high speed, dehumidifying faster.

Clothes-drying

This function will assist in drying your clothing.

Position the dehumidifier with the back of the unit facing your wet clothes.

Use the "MODE" button to select clothes-drying mode. The compressor and fan operate on high settings to blow high-speed air over your clothes, aerating and drying them.

You can also activate the swing louvre to widen the angle of drying.

At the same time, the moisture that is aerated off your clothes is removed from the air through the dehumidifier.

DEHUMIDIFICATION INSTRUCTIONS

Dehumidification Tips

While operating automatic or continuous dehumidification or clothes drying mode, you can also insert one of the HEPA or activated carbon filters to simultaneously purify the air. The appliance will tell you if there is a filter in use by illuminating the air purification indicator. See “Air purification and filters” section for more information on air purification.

EMPTYING THE TANK AND DRAINAGE

Note: See the “care and maintenance of activated carbon and HEPA filters” section for information on when to replace filters.

Plastic mesh filter

The plastic mesh filter is designed to trap large particles (such as dust and hair). This can be cleaned and reused. Please see the Maintenance section for instruction on cleaning the dust off this filter.

Activated carbon filter information

Activated carbon has a wide range of applications such as in medical and environmental applications where it is used to remove poisons and pollutants and filter drinking water.

In your home, the activated carbon filter can remove certain chemicals, volatile organic compounds, odours and impurities from the atmosphere in your home. Examples of these are pet or cigarette smells, paint and petrol fumes, burnt food smells/smoke, ammonia, CFCs, microbes and fungi.

HEPA 13 filter information

Your HEPA 13 filter removes 99.95% of the smallest particles (MPPS) from the air. This includes allergens such as dust, mould spores, pollen, dust mites as well as bacteria and viruses.

HEPA filters have been shown to reduce the spread of diseases and allergic reaction. The HEPA filter prevents the dehumidifier from re-circulating and spreading airborne bacteria and viruses that are often common in winter. The result is a healthier home and family.

Please note: You can only use one of the HEPA or activated carbon filters at a time.

Replacing activated carbon and HEPA filters

Activated carbon and HEPA filters cannot be washed. Instead they need to be replaced every 9 – 18 months (depending on the air quality in your home). An average home will need filters changed once per year. Replacement filters can be found at the retailer where you purchased this appliance.

The appliance will keep track of the number of days you have used a filter on the filter usage day counter to indicate when you should change it.

To replace a filter, turn off the appliance and remove the front panel and plastic mesh filter. Remove the activated carbon or HEPA filter by the fabric tab.

Before inserting a new filter, press the very small button in the filter cavity to reset the filter usage day counter. You may need a pen or a needle to poke the button.

Now insert your new filter taking note of the "FRONT" side of the filter. Replace plastic mesh filter and front panel.
