Meaco DD8L - Desiccant Dehumidifier Manual

PRODUCT DESCRIPTION

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.

BS PLUG WIRING

Wiring Instructions: Should it be necessary to change the plug please note the wires in the mains lead are coloured in accordance with the following code:
BLUE - NEUTRAL
BROWN - LIVE
GREEN AND YELLOW – EARTH

As the colours of the wires in the mains lead of this appliance may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows:

1. The BLUE wire is the NEUTRAL and must be connected to the terminal which is marked with the letter N or coloured BLACK.
2. The BROWN wire is the LIVE and must be connected to the terminal which is marked with the letter L or coloured RED.
3. The GREEN/YELLOW is the EARTH and must be connected to the terminal which is marked with the letter E or or coloured GREEN OR GREEN/YELLOW.
4. Always ensure that the cord grip is positioned and fastened correctly.

If a 13A (BS 1362) fused plug is used it must be fitted with a 13A fuse. If in doubt consult a qualified electrician.

Wiring for a 13Amp Plug (BS1362)

Please note. The Earth Terminal is marked with the letter E or Earth Symbol.

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.

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.
In Laundry Mode the dehumidifier will turn off after 6 hours to save energy.
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.

Ion - Turns the ioniser function on or off. An ioniser delivers negative ions into the air, these will attach themselves to positive ions (dust for example). This action makes the new particle heavier and the particle will fall to ground and will either be captured by the filter or will settle on the floor ready to be vacuumed up. The advantage of this is that you are less likely to inhale the particle which is good news if you are allergic to certain pollutants and the air will be cleaner.

*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.

PRODUCT 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 device

• 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 device

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 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.

It is possible to connect the drainage hose (NOT included in the box, please use a hose with 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.

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.

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 and not with water as this will damage the anti-bacterial properties of the filter.

Never use the device without the air filter.

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.

TROUBLESHOOTING

Check the following before contacting technical support:
