Wood’s, the World’s leading dehumidifiers Wood’s dehumidier products have been known as market leaders for many years. Their dehumidiers are suitable for use in the most demanding climates, where dehumidifying capacity is good even at lower 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 ecient and low on energy consumption. Does not wear out clothes. The amount of humidity that the dehumidier removes depends on temperature, humidity level and placement. External weather conditions may also aect the performance of the dehumidier. In cold weather the relative humidity decreases and thus the extraction of humidity from the air by the dehumidier is reduced. Therefore the dehumidier is suitable for use in the temperature range +5˚C to +35˚C. Wood’s dehumidiers are safe in operation and intended for continuous use over many years. That is why Wood’s oers a 5-year guarantee on the compressor and 2-year guarantee on other components. excessive air humidity – a danger Condensation occurs when water vapour in the air comes into contact with a cold roof, window or wall. When water vapour is cooled down, condensation occurs, and water-drops are formed. In high air humidity, the air may get musty and mould is formed, causing damage to a house and its furnishings. This environment may even cause illness for the residents, since mites and other creatures thrive in a damp environment. A dehumidier with high performance creates a good, healthy humidity level, and for greatest eciency the doors and windows of rooms that are being dehumidied should be kept closed. Removes odours, dries wood and removes moisture from sportsware outdoors equipment. A dehumidier may be used in cellars, washrooms, garages, crawl spaces, caravans, summer-houses and on boats. If the humidier is kept in colder environments, you should study the Hints at the end of the manual. Placement of dehumidifier Wood’s dehumidiers are easy to move around, all you need to have is a power source for 220/240V, but bear in mind the following: - The dehumidier should not be placed near radiators or other heat sources or exposed to direct sunlight, as it will reduce performance. - It is benecial to use a radiator or heating fan to keep the temperature above +5˚C. - The dehumidier should stand at least 25cm from a wall or other obstruction, for maximum air ow. - Ideal is to put it in the center of the room / area. note: When placed in a shower or bathing area, the dehumidier should be xed in place. It is compulsory to check and respect your local bathroom regulations before use. using the dehumidifier If the dehumidier is transported horizontally, oil may have run out of the compressor and into the closed piping system. In such a case, let the dehumidier stand for a few hours before being used. It is very important that the oil runs back into the compressor, otherwise the dehumidier may be seriously damaged.

1. Check that the water reservoir is correctly

placed and the oat moves freely in the reservoir. See the section on the Float.

2. Connect the dehumidier to an earthed

4. Set the desired humidity level by means

of the hygrostat. See the section on the Hygrostat. note: When the dehumidier is turned o, you should wait three minutes before restarting, so that the built-in automatic functions are deactivated. DS12 DS15 DS28 DS36 TDR36S ED50 Max. working area 90 m

Check that oat is free - Check that hygrostat is working. Dehumidier should start when hygrostat is in Maximum position Does not dehumidify - Check that fan is spinning - Check that air can ow freely through the dehumidier. Front grid and air lter should be clean and dehumidier should stand 20-30cm from wall - Listen for sound of compression, but bear in mind that the dehumidier may be in a dehumidifying cycle, when the compression stops. Wait initially for about 35 minutes. - Check that a thick coating of ice has not formed on the cooling coils. High noise level - Increase distance between dehumidier and surrounding surfaces - Cooling coils may be in contact with one another and cause vibration. Disconnect dehumidier from electricity and separate coils Ice formation on cooling coils - Remove air lter at rear of dehumidier and check that no dust or u is obstructing passage of air through machine - Timer which controls defrosting may be broken, in which case compression will not stop regularly No water enters reservoir - Check for obstruction to drip-tray above water reservoir Does not turn o when water reservoir is full - It is important that the oat moves freely in the water reservoir. If it does not, it will not respond to water levels and prevent dehumidier from stopping If none of the above works, you should contact your nearest retailer for checking and possible overhaul of dehumidierGB GB Operating Instructions Operating Instructions

THE FLOAT The oat consists of a white plastic cylinder which hangs on two arms. The oat rests on the surface, so it is lifted when the water level rises. When the oat reaches a certain height, the dehumidier responds to this and shuts down automatically to prevent ooding. When you have emptied the water reservoir and are to replace it in the dehumidier, this is the simplest method:

1. Push the water reservoir in until it

2. Raise the forward edge of the water

reservoir from below so that the whole water reservoir is slightly slanted.

3. Push the water reservoir home. The

oat should now be in the reservoir instead of being stuck behind it. NOTE: It is important that the oat moves freely, since its purpose is to respond to the water level and ensure that the dehumidier is turned o when it is high. A wrongly placed oat may allow the water reservoir to ood.

The dehumidier is tted with a hose connection. By attaching a hose to the dehumidier the dehumidied water can be drained directly away. Using the hose:

1. Disconnect the dehumidier from the

power source and remove the water reservoir to give access to the drip tray.

2. Attach the hose coupling to the thread

on the dehumidier and lead the hose to a drainage outlet. Check that the hose is not above the level of the drip tray.

3. Connect the dehumidier to the power

source. Without hose, direct to a drain outlet:

1. Disconnect the dehumidier from the

power source and remove the water reservoir.

2. Place the dehumidier directly over the

drain so that the dehumidied water can drip through the hole at the base of the dehumidier and into the drain.

3. Connect the dehumidier to the power

source. THE HYGROSTAT Wood’s dehumidier is tted with a built in hygrostat, or humidity controller, which is set to the desired level of humidity. The hygrostat registers the current level of humidity and ensures that the dehumidier is turned on and o automatically. How to set the hygrostat:

3. When the desired level of humidity is

reached, the hygrostat knob is turned counterclockwise until the dehumidier is turned o. NOTE: The ambient relative humidity is most simply measured with a wood’s hygrometer, and the most suitable range is between 40% and 50%.

SHUTTING OFF AUTOMATICALLY

When the water reservoir is full, the dehumidier is shut o automatically. The warning light at the front of the dehumidier comes on to show that the water reservoir should be emptied.

1. Disconnect the dehumidier from the

3. Put the empty water reservoir back and

check that the oat moves freely. See the section on the Float.

4. Connect the dehumidier to the power

The air lter at the rear of the dehumidier ensures that the cooling coils are kept free of dust. It is important that the lter is kept clean so that air can ow freely through the dehumidier. The lter should thus be cleaned when required.

1. Loosen the lter by squeezing it lightly

in the middle. This releases the xings on the sides of the lter.

2. Lift the lter out and wash it with warm

water and a mild cleansing agent. Alternatively the lter may be vacuum- cleaned.

3. Let the lter dry and put it back.

AUTOMATIC DEFROSTING Wood’s dehumidiers are tted with a timer which ensures that the cooling coils are defrosted once an hour. The timer shuts down the compressor, which causes the cooling of the coils to stop. The fan continues to draw the air at room temperature through the dehumidier and thus melts the ice, and the water runs down into the reservoir. This defrosting system means that the dehumidier works at temperatures as low as +5˚C. FAN The fan ensures that air ows through the dehumidier. Moist air is sucked in from the rear and goes via the cooling coil and the vaporizer to come out dry at the front of the dehumidier. Wood’s dehumidiers are tted with two fan speeds, except model DS12, which has only one.

• Position II – gives a high air ow with maximum dehumidifying of air.

• Position I – gives a lower air ow which causes quieter operation and somewhat lower dehumidifying capacity.

CLEANING AND MAINTENANCE

Wood’s dehumidiers require cleaning to maintain their high dehumidifying capacity. - The front grid can be vacuum-cleaned or cleaned with a brush. - The cooling coils are best cleaned with a rag and warm water. - The air lter may be washed or vacuum-cleaned. - The fan motor is permanently lubricated and requires no maintenance. NOTE: Always disconnect the cord before cleaning. HINTS: - When the dehumidier is used in extremely damp environments or when the temperature is below +10˚C, the dehumidier may stop working. A large amount of ice builds up on the cooling coil. Turn o the dehumidier and place it a little above oor 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 +5˚C. - 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. - Put in the center of the room - Increase temp. for faster dehumidication ( warm air carries more water.) - Use frost Guard if possibility temperature is below +5°C - Higher dehumidication in Autumn / Summer because outside air is warm and humid.
