WOOD’S ONE OF THE WORLD’S LEADING DEHUMIDIFIERS
Wood’s dehumidifiers have been known as market leaders for many years. Their
dehumidifiers are suitable for use in the most demanding climates,
wheredehumidifying 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 house. They are also excellent for drying
washing, attics, pool rooms and laundry. Being efficient and low on energy
consumption. Does 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 vapour in the air comes into contact with a
cold surface such as 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 a damp environments. A dehumidifier with high
performance creates a good, healthy humidity level. For greatest efficiency,
the doors and windows of rooms that are being dehumidified should be kept
closed. Removes odours, dries wood and removes moisture from outdoors
equipment.

IMPORTANT:
Installation
BEFORE FIRST USE
Let the machine stand for 4 hours before use Selecting a Location
Important
-
Dehumidifiers must be operated in an enclosed area to be most effective. Close all doors, windows, and other outside openings to the room. The effectiveness of the dehumidifier depends on the rate at which new moisture-laden air enters the room.
-
Place dehumidifier in a location that does not restrict airflow through the front of the unit.
-
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. -
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.
-
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 an grounded power
source. The power source should be 220V-240V 50Hz
