Frequently Asked Questions - GDDEY20 DIMPLEX

Why is less water collected in winter?

In winter, ambient temperature is lower and air is drier, so dehumidification capacity is reduced compared to warmer months.

Why does the dehumidifier blow hot air?

The unit extracts room air, cools it to condense moisture, then reheats the air before expelling it. This is normal operation and not a fault.

Why is the dehumidifier not working or stopped suddenly?

Possible causes: water tank is full or not installed properly, target humidity already reached, or room temperature/humidity outside operating range (5-32°C, 30-80% RH).

Is it normal for the dehumidifier to make noise?

Some noise is normal. If excessive, ensure the unit is on a flat surface, check filter cleanliness, and consider rubber pads to absorb vibration.

How do I set the timer?

Press the Timer key to set time from 1 to 24 hours. Each press increases by 1 hour. After 5 seconds without pressing, the setting is confirmed. The unit will turn off when timer expires.

How do I use continuous drainage?

Remove the water plug on the back, connect a drain hose (inner diameter 9 mm) to the outlet, and ensure the hose is not higher than the outlet for proper drainage.

What does the FL code on display mean?

FL indicates the water tank is full. Empty the water tank and reinsert it correctly to resume operation.

How do I clean the air filter?

Clean the filter and frame every two weeks with cold or warm water. Do not use chemical solvents or hot water.

What is the Inside Drying function?

It runs a 1-hour cycle to dry the inside of the unit and prevent mold. The fan runs at high speed for 30 min, then low speed for 20 min. Press the Inside Drying key to start.

How do I activate the child lock?

Long press the Mode button for 3 seconds to activate or deactivate child lock. The display shows LC when locked.

Frequently Asked Questions

Q: Why is less water stored in water tank of the dehumidifier in winter?

- In winter, the ambient temperature is lower and air is drier, therefore the dehumidification ability of the dehumidifier is lower - compared to warmer, summer months.

Q: Why isn't the unit working, or has stopped working suddenly?

● Dehumidifier may be full of water or water tank is not installed properly, drain the water in water tank, or check water tank positioning.
● The target humidity level may have been reached. Adjust target humidity level and re-check operation.
- Relative humidity of the room may be outside of operating range (30% - 80%), similarly ambient temperature of room may not be within operating temperature (5-32C).

Q: Why is hot air blown out from air supply outlet?

- This dehumidifier extracts the air in the room, and the dehumidification unit cools the air, the temperature decreases below the condensation point, the air condenses into water drops, which falls into water tank finally, and the dehumidified air is heated by the temperature returning unit. This can reduce energy consumption and also accelerate dehumidification, therefore, hot air is blown out, and this not a fault.

Q: My unit sounds too noisy, is this a fault?

- Some noise is part of normal operation, these units are not completely silent or quiet. A reasonable level of noise should be expected. If you believe this is above average, check the unit is placed on a flat surface to reduce reverberation. You may also like to check the air filter is clean. Adding rubber pads underneath the unit can absorb some residual noise too.

Installation

◆ Please drain any water from water tank before running.
During running please do not open doors and windows as much as possible, as open doors and windows will increase power usage of the product.
When the dehumidifier is installed, a certain space must be reserved around this dehumidifier, the minimum distance above is 50cm, and the minimum distance in front/rear and left/right is 20cm as required, as shown in figure below.

Operating method

Description of functions

Setting the timer

- When the dehumidifier is running, press the [Timer key] to adjust time from 1h to 24h, pressing the key once to increase the setting time by 1h. After the setting time exceeds 24h, the figure returns to 1 to restart cycle. When the set time expires, the dehumidifier turns off automatically. After the setting is selected, if you don't press the timer key again within five seconds, the set time is confirmed.

AUTO mode

- Select AUTO dehumidification, and adjust target humidity percentage. When the ambient humidity of the room is higher than the target the compressor will start and the fan will run at the chosen speed. If the room humidity is lower than the set humidity by -5% , then the compressor will stop but the fan will run at the set speed. If the ambient air is too dry (i.e. < 40% ) you may like to try our 3 in 1 Power Tower (DCEVPT8L). With three functions, the product humidifies, purifies and cools air for ultimate home comfort.

CONTINUOUS (Laundry) mode

- Select CONTINUOUS dehumidification for ongoing dehumidification regardless of relative humidity in the room. This mode is excellent for drying laundry. The compressor is in operation and the fan runs at high speed to aid in drying. Air speed can be regulated via the speed button.

INSIDE DRYING function

◆ Press the [Inside Drying key] to start drying within the dehumidifier. Procedure needs approximate 1h:
1. The dehumidifier starts at HIGH air speed and releases air continuously for 30min;
2. The dehumidifier turns to run at LOW air speed and lasts for 20min;
◆ How to stop:
1. Press the key again to cancel drying in dehumidifier, and recover to the running state before start of drying.
2. Press the [Power key] to stop drying in dehumidifier and recover to the standby state.

SWING function

To activate the swing louvre, press the Timer button and the Inside Drying button at the same time to start or end the swing function.

Drainage

1. Use of water tank

When the water tank is full of water, the full water icon on LCD flashes (the compressor and fan will stop running), the BUZZER sounds for 10 times to remind the user, until the water is drained.

Placing both hands at the side of the back cover, gently remove the water tank and open the tank cover on the right side of the body. Pour the water from the gap between water tank and the cover.

Attention: when the water tank is full of water, please empty it. Before putting the water tank into the dehumidifier, please confirm whether the floater rotates flexibly or not, and then push it in position with both hands.

2. Continuous drainage

If you do not want to drain water in the water tank frequently, you can connect a drainage pipe (with inner diameter 9mm) on the back of this dehumidifier to drain water.

◆ Find the position where the water outlet is blocked on the back, as shown in figurebelow:

Attention: the level height of externally connected water pipe shall not be higher than the water outlet, and the water pipe at rear-end shall transit smoothly, otherwise, the leakage risk exists since drainage is not smooth.

Maintenance

Precautions:

Please disconnect power supply before maintenance or repair to prevent electric shock.

If the dehumidifier is not used for a long time, please disconnect power supply.

Please do not clean the dehumidifier body with chemical solvents such as alcohol, gasoline and benzene, etc.

Please clean the water tank and its cover with soft cloth dipped in cold or warm water regularly to prevent mould inside the dehumidifier.
