WOOD’S ONE OF THE WORLD’S LEADING DEHUMIDIFIERS

Wood’s dehumidifier has been known as the market leader for many years. Their dehumidifiers are suitable for use in the most demanding climates, where dehumidifying capacity is good even at different temperatures and humidity levels. They are used with good results in premises that become damp such as cellars, garages, or summer houses. They are also excellent for drying washing, attics, pool rooms, and laundry. Being efficient and low on energy consumption. Do not wear out clothes.

The amount of humidity that the dehumidifier removes depends on the temperature, humidity level, and placement. External weather conditions may also affect the performance of the dehumidifier. Wood’s dehumidifiers are safe in operation and intended for use over many years.

EXCESSIVE AIR HUMIDITY – A DANGER

Condensation occurs when water vapor in the air comes into contact with a cold surface such as a cold window or wall. When water vapor is cooled down, condensation occurs and water drops are formed. In high air humidity, the air may get musty and mold might get formed, causing damage to a house and its furnishings. This environment may even cause illness for the residents. Mites and spiders also thrive in damp environments. A dehumidifier with high performance creates a good, healthy humidity level. For the greatest efficiency, the doors and windows of rooms that are being dehumidified should be kept closed. Removes odors, dries wood, and removes moisture from outdoors
equipment.

SET UP DEHUMIDIFIER FOR INSTALLATION IMPORTANT:

Installation

BEFORE FIRST USE
Let the machine stand for 4 hours before use
Selecting a Location

Important

1. Dehumidifiers must be operated in an enclosed area to be most effective. Close all doors, windows, and other openings to the room. The effectiveness of the dehumidifier
   depends on the rate at which new moisture-laden air enters the room.

2. Place a dehumidifier in a location that does not restrict airflow through the front of the unit.

3. A dehumidifier operating in a room will have little or no effect in drying an adjacent enclosed storage area, such as a closet unless there is adequate circulation of air in and out of the area. lt may be necessary to install a second dehumidifier in the enclosed area for satisfactory drying.

4. Ensure that the unit is placed on a stable and flat surface. If the surface is not stable there is a risk that the unit may be unstable and cause excessive vibration and that water
   will be released.

5. The dehumidifier must have at least 20 cm free space around the entire dehumidifier.

HINTS

When the dehumidifier is used in extremely damp environments or when the temperature is below +5˚C, the dehumidifier may stop working. A large amount of ice builds up on the cooling coil. Turn off the dehumidifier and place it a little above floor level so that the ice will melt away.

Sometimes it may be useful to use a frost guard or heater fan to make sure that the temperature does not fall below +10˚C. Even if the MRD20/25 work down to temperatures as low as +5°C, its capacity will increase at higher temperatures as warm air carries more water.

The hydrostat has a margin of error of approx. +/- 5-10%. At lower temperatures, the margin of error might increase further. For maximum dehumidifying power in a room, it is recommended that the air supply from outside and from adjoining rooms is minimized – close doors and ventilators.

Expect higher dehumidification capacity during Autumn / Summer because the outside air is warmer and more humid.

IMPORTANT! – Wood’s dehumidifier must be connected to a grounded power source. The power source should be 220V-240V 50Hz

Check that dehumidifier is connected to electricity and that fuse has not gone.

Check that the water reservoir is empty and correctly placed in the dehumidifier.

Does not dehumidify| The water container is full.

The water container has not been replaced correctly.

The air filter is clogged. The temperature or relative humidity in the room where the device is operating is too low.

|

Remove the water from the container.

Place the water container in the correct position. Clean the air filter.

Check that air can flow freely through the dehumidifier. The front grid and air filter should be clean and the dehumidifier should stand 20cm from the wall.

The dehumidifier works but reduces the relative humidity insufficiently.| The room is too large.

There are too many sources of humidity. There is too much ventilation

| We recommend using a dehumidifier with a larger capacity. We recommend using a dehumidifier with a larger capacity. Reduce ventilation(e.g close windows and shut doors)
If you are having trouble with your dehumidifier please refer to the troubleshooting. If none of these works, please contact your retailer for servicing of your dehumidifier.|
