PRODUCT DESCRIPTION
Air inlet filter and grill
Air outlet
Continuous drainage
Water container
Power cord
Control panel
Water level window
This dehumidifier does not come
with a hose to reduce the amount
of plastic in landfill. The majority
of dehumidifier users do not use
a hose for continuous drainage
so including one in every box just
creates waste. Hoses can be
purchased locally or direct from
Meaco.

SAFETY INSTRUCTIONS
PLEASE READ ALL INSTRUCTIONS CAREFULLY BEFORE OPERATING.
In case of a failure whilst under warranty we will collect the dehumidifier from you for
repair/replacement, therefore please save the packaging and keep it safe away from
children. When you do dispose of the packaging please recycle.
WARNING - This appliance is intended for use in a domestic environment only. Any other use is not
recommended by the manufacturer and may cause fire, electrical shocks or other injury to person or
property. When using electrical appliances, basic safety precautions should always be followed:
1. Do not operate the unit with a damaged cord or plug, after it malfunctions or has been dropped or damaged in
any way. Return to an authorized service facility for examination and repair.
2. This unit should always be kept in an upright position to avoid any damage. Locate the unit on a flat stable
surface.
3. Check the household voltage to ensure it matches the units rated specification before operating.
4. Operate this unit in an ambient temperature between 1°C and 37°C.
5. Ensure that the air inlets and outlets are not blocked or covered.
6. Do not place the unit too close to curtains or other objects - min 30cm.
7. When using the "Laundry " to speed up the drying of wet clothes in the room, keep the clothing at a safe
distance from the unit to prevent water from dropping onto the unit.
8. Never place anything on top of the unit and do not cover with any kind of material while in use.
9. This product is intended for domestic and light office use ONLY and not for commercial, industrial or outdoor use.
10. To protect against electrical shocks, do not immerse unit, plug or cord in water, or spray with liquids.
11. Never unplug the power cord without press the "Power" key to off first, as this could damage the unit. Never
unplug the dehumidifier before the fan has stopped blowing.
12. Always unplug the unit when not in use or moving location. To disconnect from the power supply, grip the plug
and pull from the power socket. Never pull by the cord.
13. Always empty the water tank before storing the unit away.
14. This appliance can be used by children aged from 8 years and above and persons with reduced physical,
sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or
instruction concerning use of the appliance in a safe way and understand the hazards involved
15. Do not run power cord under carpeting, or cover with rugs or runners. Arrange the cord away from areas where it
may be tripped over.
16. Never operate or store the unit in direct sunlight
17. To repair the unit, take it to a qualified service engineer. Repairs carried out by unqualified people may cause
damage to the unit or injury to persons or property and void the warranty.
18. Where possible, avoid the use of an extension cable as they may overheat and cause a risk of fire. Only use an
extension cord after ensuring it is in perfect condition. Extension leads can also cause voltage drop which will
affect the dehumidifier. This is more likely when being used in garages and out buildings.
19. Do not use the unit without the air filter as this will allow dirt to gather inside the dehumidifier and could invalidate
the warranty.
20. Check the filter regularly in order to keep it clean as per page 13. A dirty filter will restrict the air flow into the
machine which will increase the resistance on the fan and could result in damage and might invalidate the
warranty.
21. If the dehumidifier is knocked over then a safety tilt switch will turn it off.

THE CONTROL PANEL
Power -Press this button to turn the dehumidifier on, the unit bleeps three times when it is
turned on.
Tank Full -Lights up when the internal tank is full of water and needs to be emptied or when the
tank is incorrectly fitted.
Fault -Lights up when a fault is detected. Most common would be the air inlet being blocked
leading to the dehumidifier over heating internally. Clean the filter; make sure that the dehumidifier is not next to
a heat source (i.e. a radiator) and restart the dehumidifier after ten minutes. See the trouble shooting section at
the end of the manual.
Fan -Press the Fan button to toggle between the three fan speeds, low, medium and high.
In High fan speed the machine defaults to a Continuous running mode. Water extraction will increase in medium
and high fan speeds because the regeneration heater will switch to maximum power (this increases the running
wattage of the dehumidifier as well and the amount of heat delivered to the room).
Maximum * - Runs the dehumidifier until a relative humidity of 40%rh has been reached the
dehumidifier then it goes into the 30 minute cycle as detailed in bold below.
Normal * - Aims to achieve a relative humidity of 50%rh which will be fine for most household
applications. To prevent condensation on single glazed windows or when the outside temperature drops below
about 5°C you should use Maximum instead of Normal. Once 50% has been reached the dehumidifier then
goes into the 30 minute cycle as detailed in bold below.
Minimum * -Controls the relative humidity to 60%rh which will prevent mould from growing in the
immediate vicinity of the dehumidifier but not throughout a whole house. Once 60%rh has been reached the
dehumidifier then goes into the 30 minute cycle as detailed in bold below.

6
Laundry * -Use this mode when you want to dry washing. For optimum performance place the
dehumidifier in as small a room as possible with the door and windows closed. The dehumidifier will dry
continuously to try to achieve a relative humidity of about 35%rh which will help to dry the washing efficiently.
After 6 hours the dehumidifier will turn off.
Take care to ensure that the dehumidifier does not become covered by the washing and that no water drips onto
the dehumidifier.
Timer -Using this button turns the machine off after either 1, 2, 4 or 8 hours of use. This
setting is useful for drying washing in a set time.
*In the three modes that are controlled by the relative humidity stat (Minimum/Normal and Maximum) when
the target relative humidity has been reached the dehumidifier will stop drying the air but the fan will
continue to run for 10 more minutes. When this happens no more water will be collected, this is perfectly
normal. The fan then goes to sleep for 30 minutes after which it will wake up and sample the air so that
the dehumidifier knows when to start collecting water again, but if the relative humidity remains below the
target then the fan will go to sleep again for another 30 minutes and so on. When the relative humidity
rises again the dehumidifier will automatically start to collect water again. Although the Laundry mode
aims for a lower relative humidity it will reach a point after which there will be no more water to collect
because it will not over dry the air below a point at which the air will become uncomfortable (around 35%rh).
If one of the following events happens then the control panel will lock up and the fan light will flash.
•Temperature below 10°C
•Temperature above 40°C
•Relative humidity below 40%rh
•Machine has been working hard and needs to cool down internally
If you find that this happens and none of the buttons on the control respond, then do not worry, this is normal
and the dehumidifier is still drying the air as per the setting you left it in. The control panel will start to work again
when the conditions allow.
Occasionally you might notice the temperature of the air coming out of the dehumidifier will feel cooler. This is
perfectly normal and part of the overall dehumidification process whereby the heater is rested during the
regeneration process for the desiccant wheel.

DEHUMIDIFIER SETUP AND USE
•Place the dehumidifier in an upright position on a stable, flat surface.
•Please ensure the unit is a safe distance away from a wall or furniture.
•Please keep clothes at a safe distance of 30cm away from the air inlet or outlet to prevent water from dripping into the unit.
•Ensure the tank is correctly fitted, if the tank is full or is not in place, the “Empty Tank” light comes on, an alarm will sound
and the dehumidifier will turn off.
•Press the Power button , you should hear some bleeps.
•Select the Mode that you want to use the dehumidifier in, for most applications this will be the “Normal” mode.
•To turn off press the Power button again.
Where to position the dehumidifier
•For best results position the dehumidifier somewhere central like a landing or a hallway. As long as the internal doors are open
the moisture will migrate naturally towards the dehumidifier to be processed.
•To dry washing it is best to put the dehumidifier into a small room with some heating on. Close the door and windows and use
the dehumidifier in “Laundry” mode. Hang the clothes so that they are not touching each other and so that air can circulate
between the clothes. Ensure that water does not drip onto the dehumidifier.
Smell coming from the dehumidifier
When you first use the dehumidifier and periodically afterwards you might notice a smell coming from the dehumidifier. This is
caused by the Zeolite desiccant material and is not a sign that the dehumidifier is faulty, nor is it harmful to humans or pets. The
smell occurs because the Zeolite absorbs odours from items like cigarettes, cosmetics, hair sprays, building materials and new
furniture and then when the desiccant is heated the smell is discharged into the room. This smell has been described as being like a
burning smell or a sour smell. It is normal, will not last long and is not a sign of a fault. You can clear it by running the dehumidifier
in a separate space like a garage or if it is dry –outside.
Amount of water collected
•When you first use your dehumidifier it will work harder to reduce the room humidity down to 50%rh (in “Normal”
mode). This is the time when it will produce the most water and need emptying most frequently. As the room
becomes dryer the dehumidifier collects less water and takes longer to fill the tank, this is perfectly normal.
When the target relative humidity has been reached the dehumidifier will stop collecting water, again this is
normal.
•If you find that you still have condensation on your windows or you need to dry the air further then us the
“Maximum” mode. This might well be necessary if you have single glazed windows or if the outside air
temperature drops towards freezing.
•In the three modes that are controlled by the relative humidity stat (Maximum/Normal/Minimum) when the target
relative humidity has been reached the dehumidifier will stop drying the air and will then run the fan for 10

8
minutes to make sure that the relative humidity is stable. When this happens no more water will be collected,
this is perfectly normal. The fan then goes to sleep for 30 minutes after which it will wake up and sample the air
so that the dehumidifier knows when to start collecting water again, but if the relative humidity remains below the
target then the fan will go to sleep again for another 30 minutes. When the relative humidity rises again the
dehumidifier will automatically start to collect water again.
•Although the Laundry mode aims for a lower relative humidity it will reach a point after which there will be no
more water to collect because it will not over dry the air below a point at which the air will become uncomfortable.
Turning off
When you press the Power button to turn your dehumidifier off the fan will run for another ten minutes before
it shuts down. This is normal and part of an essential process to cool the inside of the dehumidifier down.
Please do not try to interrupt the cooling down process by unplugging the dehumidifier from the wall socket,
the machine will turn off once the ten minutes as past.
To operate safely
•Do not insert small objects into the unit or this will damage it and cause a hazard.
•Do not remove the tank when the dehumidifier is running or water may leak.
•Minimum operating condition 1°C at 40%rh relative humidity.
ATTENTION !
⚫
Never use the device with a damaged power cord, plug, cabinet or control panel. Never trap the power cord or
allow it to come into contact with sharp edges.
⚫Failing to follow the instructions may lead to the guarantee becoming void.

EMPTYING THE WATER
Continuous Drainage
When the water container is full:
The DD8L will stop dehumidifying and the fan will stop after a cool
down period.
The DD8L will then bleep and the Empty Tank LED will flash
Empty the water container and replace it in the correct position.
The dehumidifier will start to work again.
If the “Empty tank” light stays on and the unit does not start up then the tank is not correctly fitted.
Continuous Drainage
It is possible to connect the drainage hose (NOT included in the box, please use a hose with an 8mm internal
diameter) to the dehumidifier for permanent water drainage. Simply connect the hose to the drain spout and ensure
that the end of the hose is lower than the drain opening, otherwise the water will not drain and flooding may occur.
Water spigot
If you find that the water does not flow down the hose then check that it is running downhill, is not kinked, all excess
tube has been cut off and is not blocked. If the water still does not flow then make a 4mm hole, 30mm from the spout
in the top of the hose. This will balance out the air pressure and allow the water to flow.
When you no longer wish to use the permanent water drainage, disconnect the drainage tube from the device. Ensure
that the water container is positioned correctly.

10
CLEANING
Switch the dehumidifier off and remove the plug from the socket before cleaning.
The exterior
Clean the exterior with a soft, dry cloth. If the device is extremely dirty, use a mild cleaning agent. Wipe the
dehumidifier with a slightly damp cloth. Never spray the device with water.
The air filter
When used regularly, the filter may become clogged with dust and particles. Therefore the filter should be cleaned at
least every two weeks. Follow these steps:
1. Remove the filter.
2. Clean the filter with a vacuum cleaner or with a mild solution of washing up liquid. Make sure that the filter is
drained and dried before putting it back in the dehumidifier.
STORAGE
If the machine will not be used for a long period of time, take the following steps:
1. Remove the plug from the socket and empty the container. Allow the container and the dehumidifier to dry
completely.
2. Clean the air filter.
3. Store the device in a dust-free location away from direct sunlight, preferably covered with a sheet of plastic.
Never use the device without the air filter or with a dirty filter.

TROUBLESHOOTING
Check the following before contacting technical support:
Problem
Cause
Solution
The unit does not
work.
The power is not connected.
Insert the plug into the wall outlet.
The device does not
dehumidify.
The water container is full.
Remove the water from the container.
The water container has not been replaced
correctly.
Place the water container in the correct position.
The air filter is clogged.
Clean the air filter.
The temperature in the room where the
dehumidifier is operating is too low.
The machine does not dehumidify below 1°C, it is
highly unlikely at that temperature that there is
any moisture to remove anyway.
The relative humidity in the room where the
dehumidifier is operating is too low.
The dehumidifier dries down to the target relative
humidity set and then goes into fan only mode
until the relative humidity goes above the set
point again.
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 small five bedroom house.
We recommend using a dehumidifier with a
greater capacity.
There are too many sources of moisture.
Bathing, washing, drying clothes and cooking all
puts moisture into the air. Portable 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 portable gas heater.
There is too much ventilation.
Reduce ventilation (e.g. close windows and shut
doors.)
The air filter is blocked and the reduce air flow is
effecting performance.
Clean the air 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 Maximum and run it 24
hours a day.
I cannot remove the
condensation from
my windows, even in
Maximum 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 Maximum 24
hours a day and when the air temperature
outside increases the windows should clear of
condensation.
Dehumidifier is
blowing out warm
air.
The dried air is passed over a heating element
before it is blown into the room as part of the
dehumidification process.
This is normal, a dehumidifier is not an air cooler.

Problem
Cause
Solution
Knocking noise
coming from the
dehumidifier
Motor that rotates the desiccant wheel is low on
lubrication.
Run the dehumidifier in Laundry mode for two
days to increase the lubrication, if fault persists
then call Meaco.
Alarm light on
continuously
Restricted airflow to the dehumidifier or
temperature below freezing.
Clean the filter and make sure that the unit is
more than 30cm from a wall. If the temperature
is below freezing then use the dehumidifier when
the space warms up again.
Alarm light flashing
Restricted airflow to the dehumidifier.
Clean the filter and make sure that the unit is
more than 30cm from a wall.
Water not draining
down the hose
Hose is fitted for continuous drainage but the
water still goes into the tank.
Negative air pressure in the room is pulling the
water back into the dehumidifier overflow. Insert
a 4mm hole into the top of the tube 30mm down
from the spout. This will introduce air into the
tube and balance out the air pressure.
Dehumidifier leaks
water onto the floor
Usually means that the dehumidifier is not on a
level surface or that the filter has not been
cleaned often enough and dirt has fallen into the
dehumidifier.
You can also check that the water bucket is not
cracked by filling it with water and placing it on
kitchen paper on the kitchen side.
Machine not
switching off and on
in the usual 30
minute pattern
Temperature and relative humidity sensor that
reads the room reading is unable to read the
correct readings.
Clean the filter and blow the air sensor with a hair
dryer on fast setting to clear the sensor of dirt.
Unplug the dehumidifier for 10 minutes to reset
it’s circuits and then turn back on.
Unit only works in
Laundry mode and
Laundry light stays
on or flashes.
If the humidity sensor is faulty then the
dehumidifier will only run in Laundry mode.
Try clearing the sensor as per above line, if that
fails then call Meaco for a repair.
Medium fan speed
light flashes
None of the buttons work.
This is normal and the unit is functioning ok.
The unit will return to normal operation when
conditions allow. More details below.
If one of the following events happens then the control panel will lock up and the fan light will flash.
•Temperature below 10°C
•Temperature above 40°C
•Relative humidity below 40%rh
•Machine has been working hard and needs to cool down internally.
If you find that this happens and none of the buttons on the control respond, then do not worry, this is normal and the
dehumidifier is still drying the air as per the setting you left it in. The control panel will start to work again when the
conditions allow.
