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
dehumidier responds to this and shuts
down automatically to prevent ooding.
When you have emptied the water
reservoir and are to replace it in the
dehumidier, this is the simplest
method:
1. Push the water reservoir in until it
touches the oat.
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
dehumidier is turned o when it
is high. A wrongly placed oat may
allow the water reservoir to ood.
DRAINAGE OF WATER
The dehumidier is tted with a hose
connection. By attaching a hose to the
dehumidier the dehumidied water
can be drained directly away.
Using the hose:
1. Disconnect the dehumidier 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 dehumidier and lead the hose
to a drainage outlet. Check that the
hose is not above the level of the drip
tray.
3. Connect the dehumidier to the power
source.
Without hose, direct to a drain
outlet:
1. Disconnect the dehumidier from the
power source and remove the water
reservoir.
2. Place the dehumidier directly over the
drain so that the dehumidied water
can drip through the hole at the base of
the dehumidier and into the drain.
3. Connect the dehumidier to the power
source.
THE HYGROSTAT
Wood’s dehumidier 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 dehumidier is turned on and
o automatically.
How to set the hygrostat:
1. Set the hygrostat knob to the
Maximum position.
2. Set the fan to position II
(does not apply to DS12).
3. When the desired level of humidity is
reached, the hygrostat knob is turned
counterclockwise until the dehumidier
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
dehumidier is shut o automatically.
The warning light at the front of the
dehumidier comes on to show that the
water reservoir should be emptied.
1. Disconnect the dehumidier from the
power source.
2. Empty the water reservoir.
3. Put the empty water reservoir back and
check that the oat moves freely. See
the section on the Float.
4. Connect the dehumidier to the power
source.
THE AIR FILTER
The air lter at the rear of the
dehumidier 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 dehumidier.
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 dehumidiers 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
dehumidier and thus melts the ice, and
the water runs down into the reservoir.
This defrosting system means that the
dehumidier works at temperatures as
low as +5˚C.
FAN
The fan ensures that air ows through
the dehumidier. 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 dehumidier. Wood’s
dehumidiers 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 dehumidiers 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 dehumidier is used in
extremely damp environments or when
the temperature is below +10˚C, the
dehumidier may stop working. A large
amount of ice builds up on the cooling
coil. Turn o the dehumidier 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
dehumidication ( warm air carries
more water.)
- Use frost Guard if possibility
temperature is below +5°C
- Higher dehumidication in Autumn /
Summer because outside air is warm
and humid.
