This dehumidifier is designed to reduce humidity from the air in a building or part of a building. The purpose is to help dry laundry, prevent condensation, mould, musty air and other issues associated with high relative humidity.
The time necessary for the dehumidifier to dry a room and reach the desired relative humidity depends on the environmental conditions prevailing within the room. For example, the number of air changes with outside, any sources of moisture, and the room temperature can all either speed up or slow down the dehumidification process.
The dehumidifier functions according to the condensation principles with heat recovery. The fan takes the humid air from the room, in and across a filter, and then through an evaporator. Here the air is cooled below dew point, so that the water vapour of the air forms a condensate on the coils, which flows into the internal container ready to be poured away. The cooled and dried air is heated again by a condenser. By recycling the room air through the dehumidifier repeatedly, the moisture content and relative humidity of the air is reduced.
For installation and transportation, the following instructions must be considered:
12L LOW ENERGY DEHUMIIDIFIER/AIR PURIFIER
20L LOW ENERGY DEHUMIIDIFIER/AIR PURIFIER
As a company we understand the urgency of Climate Change and recognise how important it is to play our part in becoming more environmentally friendly. For this reason, we have stopped including continuous drainage hoses in our dehumidifiers to reduce the amount of plastic waste created, as most of our customers do not use them. If you would like to use the continuous drainage option on your dehumidifier, you can purchase a hose from www.meaco.comor you can use a garden hose that has an internal diameter of 12mm (12L Low Energy) or 14mm (20L Low Energy).
If you wish to drain water away continuously and not empty the water tank, a hose can be attached as per the images below. Make sure the hose runs downwards, with no kinks, bends or blockages, to allow water to run out of the unit via gravity.
12L LOW ENERGY DEHUMIIDIFIER/AIR PURIFIER
In order to use continuous drainage, remove the water tank from the unit. Remove the rubber bung from the water tank and insert it into the spout which drips into the water tank. Snip the circular disc on the back of the unit (to the bottom right of the filter) and push the 12mm hose through the hole securing it to the internal outlet pipe. Once the hose is in place, put the water tank back into the unit (for continuous drainage to work, the water tank must always be in place).
20L LOW ENERGY DEHUMIIDIFIER/AIR PURIFIER
In order to use continuous drainage, take the plug off the back of the unit and push the 14mm hose through the hole securing it to the internal outlet pipe (for continuous drainage to work, the water tank must always be in place).
The water tank is found on the front of the unit on the 20L model and at the back of the unit on the 12L model. In order to empty the water tank, simply pull the tank out from the unit and empty the water. The lid does not need to removed as the water can be poured out of the hole at the corner. The water collected can be used to water non-edible plants only – do not consume.
If you want to clean the inside of the 20L Low Energy water tank, the lid needs to be removed via the handle. Turn the handle to align the handle grooves with the circular holes on the water tank. Gently squeeze both sides of the handle inwards and lift the handle clear. You will then be able to remove the water tank lid.
Please note, located inside the water tank is a float. It is essential this float is NOT removed from the water tank. The float measures the level of water in the water tank and triggers the sensor to turn the dehumidifier off when the water tank is full.
ON/OFF BUTTON
When the dehumidifier is plugged into a wall socket, the dehumidifier will bleep and the display will remain blank. Press the ON/OFF button to turn the dehumidifier on or off.
UP AND DOWN ARROWS (use to set target humidity level)
The UP and DOWN arrows can be used to select a target relative humidity between 30%rh and 80%rh, CO mode or AP mode. Press the UP or DOWN arrow until you reach your desired target relative humidity. The dehumidifier will run until the target humidity level has been reached. If you choose CO mode, the dehumidifier will run continuously and never stop. If you choose AP mode, the dehumidifier will just purify the air and not collect any water.
The UP arrow will go through the settings in the following order: AP-CO-30-35-40-45- 50-55-60-65-70-75-80.
The DOWN arrow will go through the settings in the following order: 80-75-70-65-60- 55-50-45-40-35-30-CO-AP.
OFF TIMER BUTTON
The OFF Timer acts as a countdown timer. This can be used if you want the dehumidifier to run for a set number of hours and then switch off. Press the OFF-Timer button and then use the UP and DOWN arrows until you reach the desired number of hours you want the dehumidifier to run for (it can be set between 1 and 12 hours). This is not a daily run timer and needs to be set each time you wish to use it.
DEHUMIDIFICATION LIGHT
The LED light under the droplet stays on permanently, even once the dehumidifier has reached its target humidity level.
DEFROST MODE
This dehumidifier is equipped with an automatic defrosting system. When operating in low temperatures, the surface of the evaporator will accumulate frost which effects the efficiency of the dehumidifier. When this happens, the machine will automatically go into periodic defrosting and the LED light beneath the snowflake symbol will appear. The time the unit is in defrost mode will vary. This is not a fault; it is part of the dehumidification process. It is not recommended to use the dehumidifier in temperatures below 5°C.
WATER TANK FULL INDICATOR
When the water tank is full the dehumidifier will bleep multiple times and then switch off. Once the water tank has been emptied and placed securely back in the dehumidifier, the dehumidifier will start to run again as per its previous settings.
CHILD LOCK
Press both the UP and DOWN arrows at the same time for three seconds to activate child lock, LC will appear on the display. This stops the functions of the dehumidifier from being changed. The dehumidifier cannot be turned off when child lock is activated. To deactivate child lock, press the UP and DOWN arrows at the same time again for three seconds.
LOUVRE
The louvre can be manually adjusted and must always be kept open when the dehumidifier is in use. When using the dehumidifier to dry laundry, we recommend using the louvre to direct the airflow towards the laundry. Please note, the wider the angle the louvre is adjusted to, the less noise the dehumidifier will make.
When the dehumidifier is switched ON, the reading on the display will show the current relative humidity level in the environment the dehumidifier is being used in.
When the DOWN arrow is pressed once, the display will show the mode the dehumidifier is set to, for example, it will either show the target humidity level set, AP or CO. We recommend setting the dehumidifier to reach a target humidity level of 50%rh or 55%rh. After two seconds the display will then revert to the currently relative humidity level in the environment. For more information of AP or CO mode.
Once the target humidity level has been reached (is more than 3% below) the dehumidifier will go to sleep for half an hour and the reading on the display may increase significantly, this is because the dehumidifier is reading its internal humidity level, it is not showing the external relative humidity level in the environment.

This is not a daily run timer and needs to be set each time you wish to use it.
FAN SPEED BUTTON
Press the Fan Speed button to choose between one of two different fan speeds: low, and high. The LED lights on the display underneath the two fan icons will change highlighting the fan speed currently in use. The icon on the left of the display is high fan speed, the icon on the right is low fan speed.
LOUVRE SWING BUTTON
Press the Louvre Swing button to turn the swing mode on or off. When switched on, the LED light will show, and the louvre will automatically move up and down distributing the air evenly. When the louvre swing is switched off, the louvre can be moved into a fixed position manually in order to direct the airflow. It must always be kept open when the dehumidifier is switched on.
DEHUMIDIFICATION LIGHT
The LED light under the droplet and snowflake will stay on permanently, even once the dehumidifier has reached its target humidity level. This light will be solid, it will not flash. If the light is flashing, it is in defrost mode.

HEPA filters provide excellent air cleaning capabilities. If you are allergic to mould spores, pollen, dust, pet dander, dust mites etc. then a HEPA filter will help. These are True HEPA filters which mean they conform to tough international standards to ensure that they capture 99.97% of particles that have a size of 0.3µm or larger, complying to class E11. These are the best filters for cleaning the air that you can currently get on a dehumidifier.
The use of a HEPA filter effects the performance of the dehumidifier as follows:
Meaco 12L Low Energy Dehumidifier: 11% less dehumidification and 7% increase in energy consumption.
Meaco 20L Low Energy Dehumidifier: 9% less dehumidification and 5% increase in energy consumption.
If the HEPA filter is in place, regardless of the setting, all the air going through the dehumidifier will be purified.
The dehumidifier can be used in AP, Air Purification mode. To achieve this mode keep pressing the DOWN arrow until AP appears on the display. In this mode, the dehumidifier will not collect any water but all the air that goes through the dehumidifier will be purified of dust, dirt, bacteria and allergens. The HEPA filter must be installed.
Once the HEPA filter changes colour from white to grey, it must be replaced. Replacement HEPA filters can be purchased from www.meaco.com.
In order to achieve this mode, keep pressing the DOWN arrow unit CO appears on the display. In CO mode the dehumidifier will not stop, it will continue to dry the environment regardless of the room relative humidity. This is the recommend setting for drying your laundry.
When the dehumidifier is switched off, using the ON/OFF button, when turned back on the dehumidifier will continue to run in the same settings it was previously running on. When the dehumidifier is switched off by the mains, or due to a power cut, when turned back on the dehumidifier will run with a target of 50%rh.
If you wish to reset the dehumidifier to its factory default settings switch the dehumidifier off using the ON/OFF button, unplug it from the mains, wait a few minutes, plug it back into the mains and then switch the unit back on using the ON/OFF button.
When the room relative humidity is more than 3%rh below your target relative humidity the dehumidifier will stop drying the air, but the fan will continue to run for a few minutes. If the relative humidity is stable, then the dehumidifier will go to sleep for 30 minutes.
During this sleep time the humidity reading on the display will probably increase well above the set point. This is because the fan is turned off and the sensor is now reading the relative humidity inside the dehumidifier where it is cold and wet. This is normal and the machine will not turn back on because this is the reading inside the dehumidifier and not the room reading.
After 30 minutes the dehumidifier will wake up and sample the air with just the fan running for 2 minutes so that the relative humidity sensor can tell the control panel what the room relative humidity is, if the relative humidity is more than 3%rh above the set point then it will start to dehumidify again, if not then the fan will go to sleep again for another 30 minutes.
For general use we recommend setting the dehumidifier to reach a target humidity level of 50%rh or 55%rh and positioning the dehumidifier in a central position within your home, for example the landing or hallway. If you have more of a problem in one area of your house/flat, place the dehumidifier closer to that area. Leave all the interior doors open and keep the windows closed. Moisture in the air, from the entire house, will migrate towards the dehumidifier allowing the machine to reduce the relative humidity level. For best results, leave your dehumidifier running 24/7.
Please note, when you first start using your dehumidifier, you may find it will run continuously, collecting a large amount of water, or struggling to reach the target humidity level. This is completely normal. There will be a lot of excess water in the environment that the dehumidifier needs to remove, meaning it must work a lot harder. After a few weeks, the humidity level will stabilise meaning your dehumidifier will run less frequently and collect less water.
To dry laundry faster, place the laundry and the dehumidifier into as small a room as possible, with all the doors and windows closed. Position the dehumidifier so that its dry air can hit as large an area of washing as possible and position the laundry so that the air can circulate around them. Make sure water from the laundry is not able to drip onto the dehumidifier. If possible, use a pedestal fan to speed up the airflow and push more dry air across more of the laundry. Some warmth in the room will also help. Set the dehumidifier to run on CO mode and the highest fan speed (please note the 12L model only has one fan speed).
Always turn off the power and disconnect the main cable before performing maintenance procedures.

CLEANING THE EXTERIOR
CLEANING THE FILTER
The filter is a life-long filter which should not need to be replaced (other than for wear and tear reasons). When used regularly, the filter may become clogged with dust and dirt particles. The filter must be cleaned a minimum of every two weeks (not doing so could invalidate the units' warranty). Please use the following steps:
The HEPA filter is not life-long and must be replaced when the colour changes from white to grey (it depends on the environment the dehumidifier is being used in, but the HEPA filter will need replacing roughly every 3 months). The HEPA filter can be hoovered every so often in order to remove any dust or dirt.
Using a HEPA filter is optional. The dehumidifier can be used without the HEPA filter, this means it will just dehumidify the air and not purify it.
Replacement HEPA filters can be purchased from www.meaco.com.
Please see below two images demonstrating how to insert the HEPA filter:

Ambient temperature exceeds 35°C (C2 appears on the display and you will hear 3 long bleeps and 2 short bleeps). | Under this condition the compressor is overloaded and switches off automatically. It is recommended to switch off the dehumidifier. | |
The ambient air humidity is lower than 45%rh. | Under this condition the dehumidifier becomes inefficient and little water will be collected. | |
The air filter is dirty and blocked. | The air filter must be cleaned. If the air filter is beyond cleaning, it must be replaced. | |
The actual humidity is below the target humidity set point. | This is normal and is not a fault. | |
The unit is in Air Purification (AP mode). | Use the arrows to change the dehumidifier into another mode. | |
The dehumidifier works but reduces the relative humidity insufficiently/there is little water in the water tank | The house is too large. This dehumidifier can dry up to about a three/five bedroom house (12/20L). | We recommend using a dehumidifier with a greater capacity. |
There are too many sources of moisture. Bathing, washing, drying clothes and cooking all add moisture to the air. Bottled gas heating can add too much moisture into the air for a dehumidifier. | We recommend using a dehumidifier with a greater capacity. Consider using a different heat source to a bottled gas heater. | |
There is too much ventilation. | Reduce ventilation (e.g. close windows and shut external doors.) | |
The air filter is blocked and the reduced air flow is effecting performance. | Clean the air filter/replace the HEPA filter. | |
The windows were clear and now condensation has returned | The outside air temperature has dropped and the windows are colder. | Use the dehumidifier on a lower relative humidity setting and run it 24 hours a day. |
I cannot remove the condensation from my windows, even in continuous mode | The surface temperature of the windows is too low for a dehumidifier to prevent condensation. Common with single glazed windows and when the outside air temperature drops below freezing. | Keep running the dehumidifier on continuous mode 24 hours a day, when the air temperature outside increases the windows should clear of condensation. |
Dehumidifier is blowing out warm air | The dried air is passed over heating coils before it is blown into the room as part of the dehumidification process. | This is normal, a dehumidifier is not an air cooler. |
Dehumidifier is blowing out cold air | The dehumidifier does not cool the air, the air might feel cooler because it is moving in the same way as the air from a fan in summer feels cooler. | The room temperature will not be reduced by the dehumidifier and it is not cooling the air. |
The display is not showing the humidity set point | The display shows the room relative humidity not the set point. | Press the up or down buttons once to see the target relative humidity. |
I cannot change the set point, I get stuck on CO | You have been pressing the UP or DOWN button and have reached CO. | Press the opposite button to cycle in the other direction through the humidity options. |

E2 Error Code | The humidity sensor is broken. The unit still dehumidifiers but in continuous mode only. | Please contact Meaco. |
This dehumidifier must not be used in rooms under the following conditions:
Keep Children Away: Do not allow children to play with or around this unit, which could result in injury. Be sure the unit is inaccessible to children when not attended. This appliance is not intended for use by person (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliances by a person responsible for their safety.
Keep Unit Grounded: Always operate the unit with a grounding plug and a grounded electrical outlet. A grounding plug is an essential safety feature that helps reduce the risk of shock or fire.
Protect Power Cord from Damage: Never operate a unit with a damaged power cord, as this may lead to electrical or fire hazards. If the power supply cord is damaged, it must be replaced by a cord of the same type and amperage rating.
Extension Cords: Extension cords must be grounded and able to deliver the appropriate voltages to the unit.
Handle with Care: Do not drop, throw or crash the dehumidifier. Rough treatment can damage the components or wiring and create a hazardous condition.
Run on Stable Surface: Always operate the unit on a stable, level surface, for example the floor or a strong counter, so that the dehumidifier cannot fall and cause injury.
Keep Out of Water: Never operate the unit in pooled or standing water, as this may create a risk of injury from electrical shock. Do not store or operate outdoors. If electrical wiring or components become wet, thoroughly dry them before using the unit. If in doubt do not use the dehumidifier and consult a qualified electrician or a Meaco approved engineer.
Do Not Let Water Drip onto the Dehumidifier: Dry your bathroom by placing the dehumidifier outside of the room with the bathroom door open. Do not use your dehumidifier inside the bathroom.
Keep Air Intakes Clear: Do not clog or block the air intakes by placing the dehumidifier too close to curtains, walls or anything that will restrict the air inlet. This may cause the unit to overheat and result in a fire or electrical hazard.
Keep the Filter Clean: There is a filter on the air inlet to stop dust from getting inside the dehumidifier. If you allow the dust and dirt to build up on the filter, pressure on the fan motor will be increased and you will reduce the amount of water extracted from the air. Not cleaning the filter reduces the lifespan of the dehumidifier, increases energy consumption and decreases water extraction. Please examine and clean the filter every two weeks minimum.
Keep Electrical Components Dry: Never allow water inside the dehumidifier's electrical components. If these areas become wet for any reason, thoroughly dry them before using the dehumidifier. If in doubt, do not use the dehumidifier and consult a qualified electrician or a Meaco approved engineer.
