Intended use
The dehumidifier is designed only for use for dehumidifying in privately used rooms
(e.g. living rooms, bedrooms, storage areas or basements). The user must observe all
the operational parameters specified in this manual.
The device is allowed to be used only for its prescribed purpose. Any other use
is deemed to be a case of misuse. The user/operator and not the manufacturer will be
liable for any damage or injuries of any kind resulting from such misuse.
Operating instructions
The device is designed for a temperature range of between 5°C and 35°C. At below
5°C the humidity level tends to be very low, such that there is no need for a
dehumidifier. At above 35°C it is possible that the overheating guard will shut the
device down automatically.
The device does not have approval for operation outside the given temperature range.
To enable the dehumidifier to dehumidify the air to optimum effect, it warms the air.
The room temperature may therefore rise by 1-2 degrees. This is perfectly normal
and increases the efficiency of the device.
To operate efficiently in energy terms, the device switches off automatically once the
set humidity level has been reached. If the humidity level increases again, the device
switches on again automatically.
Always take the device from the front when you want to carry it.
The device switches off automatically when the water tank is full.

Setting up instructions
Remove all strips of adhesive tape which were used as transport braces. Make sure
that the device is stood securely on a dry surface.
Ensure that the device cannot cause any water damage if water were to escape
from water tank.
Before you start the device, always let it stand in its final position for at least 2
hours to allow the refrigerant to settle and ensure that there is no risk of damage to
the compressor.
Make sure that the device is not exposed to direct sunlight.
Check that the float is correctly positioned and moves easily.
Make sure that the water tank is correctly positioned.
Make sure that the socket outlet is fitted with a residual current protective device
circuitbreaker (earth-leakage circuit-breaker).
If you are unsure whether this is the case, ask your electrician or use a personal
protection plug (available from your DIY store).
To save power and to avoid potential danger, disconnect the device when it is not
operated.
Before starting up
Make sure, that the unit is switched off.
Starting up
Check the cable for damage before you insert the power plug. The device may only be
used if the power cable is in flawless condition. Plug in the power cable and switch the
unit with the ON/OFF switch.
IMPORTANT: Always allow the device to run for at least 35 minutes before you
switch it off, and never switch it on and off continuously in quick succession.
Otherwise there is a risk of damage to the compressor.
When the product shut down, please wait at least 3 minutes before moving the unit,
so that all water can run into the water tank.
The higher the humidity in a room and the higher the temperature in that room, the
more effectively the Comedes Demecto 70 can dehumidify the air.
The compressor therefore generates heat and warms up the air in the room. This is
perfectly normal and is no cause for alarm.

the display, then the current humidity is displayed again.
If you press the timer button again, the current run time will be displayed again for 5
seconds.
Humidity setting:
The device is equipped with a modern hygrostat (humidistat) and turns off
automatically after the desired humidity is reached, to save power.If the humidity
increase in the room again, the Comedes Demecto 70 will automatically restart.
Repeatedly pressing the humidity setting button, a target humidity of CO, 30%, 35%,
40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90% and AU could be
set. The hysteresis of the device is approximately 3%.
During operation, the current humidity is displayed on the display. If the actual
humidity is below 35% the display will show „LO“. When the humidity is above 95%
the display will show „HI“.
Memory Function
The unit has a memory function that saves the fan speed and target humidity setting
when the unit is switched off. If the dehumidifier is switched on again, it starts with
the saved settings.
Continuous operation (CO):
With the setting „CO“, the unit will dehumidify with maximum capacity and won‘t
switch off till the water tank is full.
Comfort mode (AU):
With this setting, the unit operates in an automatic mode, which is influenced by
temperature.
1. At a temperature below 5 ° C, the compressor stops.
2. At a temperature between 5 ° C and 20 ° C, a target humidity of 60% is
automatically set.
3. At a temperature between 20 ° C and 27 ° C, a target humidity of 55% is
automatically set.

ENG-10 www.comedes.com
Emptying water tank:
If the water tank is full, the Comedes
Demecto 70 switches off automatically and
the red LED (tank “full” indicator, Fig. 3) will
light up. You need to empty the water tank
before you can continue using the Demecto 70.
Hose drainage
The Comedes Demecto 70 can also be operated
with a drainage hose. To do so, remove the water
tank and fix a drainage hose Ø12mm (not
included). Put the hose into the recess on the
tank, insert the tank again and guide the hose
into a drain channel. Make sure that the drain is
not higher than the connection on the device, to
ensure that the water can drain off unhindered.

Recommendations for drying with the Comedes Demecto 70
To achieve the best possible dehumidifying results with the Demecto 70 while using
as little energy as possible, we offer the following tips: Since this manual can only
offer a limited amount of advice, we would recommend that you consult the
more detailed information available at: www.luftentfeuchter-tipps.de
Basic principles of dehumidifying with the Comedes Demecto 70
The dehumidifier works in a similar way to a refrigerator with a refrigeration machine.
This generates a cold surface (on the vaporizer) on which water condenses.
Depending on the humidity and ambient temperature the water condenses at dew
point temperature. To enable the dehumidifier to dehumidify, the temperature of the
cold surface must be below the dew point temperature. Given that the water would
freeze if the dew point temperature was negative, the dehumidifier only works if the
dew point temperature is positive. To ensure that this is the case, the dehumidifier is
equipped with a modern, temperature-controlled automatic defroster which maintains
the vaporizer temperature between approximately 0°C and 5°C. For effective
dehumidifying the dew point temperature for the Demecto 70 needs to be above
5°C. If the dew point temperature is below this level, dehumidifying will either not be
possible at all or only very inefficiently. Refer to the following table to determine the
dew point temperature in your particular case. Where dew point temperatures are too
low it is advisable to turn on the heating. Gas radiant heaters are not suitable
therefore.
Drying to deal with problems with condensation damp
Condensation damp generally occurs in basements when moist air penetrates the
basement in summer and condenses on the cold walls of the basement. We
recommend that you dehumidify the basement, room by room, in continuous
operation. To start, run the device in continuous operation mode until you see that
the amount of water that you are emptying out of the tank each day starts to reduce.

ENG-12 www.comedes.com
Then move the device to the next room. Once you have dried all the rooms in this
way we recommend that you select a central location for the device
and then run it in automatic mode. We recommend a humidity setting of arround
50% to 60%.
This method of dehumidifying is more efficient in energy terms than dehumidifying in
automatic mode from the start, because if you do that, the device will switch
on and off a lot.
Drying to deal with building defects or water damage
In the case of building defects or water damage, the cause needs to be eliminated
first. Once this has been done the rooms can be dried using condensation driers such
as the Demecto 70. In this case the dehumidifier is run in continuous operation mode.
The ambient temperature needs to be at least 20°C (but not above 27°C). Additional
heating can be provided by an electric heater if necessary. Gas radiant heaters are
not suitable! To generate the air circulation required, fans can be used in the room.
Please note that the insulation layer may also need to be dried, depending on the
nature of the building defects. This will have to be undertaken by a specialist firm.
Recommended humidity levels for rooms
As a general rule this is dependent on the ambient temperature. The higher the
temperature of the room, the lower the setting for the relative humidity needs to be,
otherwise it will encourage the growth of fungus or mold in the room. A pleasant level
of humidity is between 35% and 65% relative humidity, depending on the ambient
temperature. The following diagram provides a point of reference for the optimum
level of humidity at different ambient temperatures.
The diagram is based on the assumption that temperatures >=20°C are for living
quarters and temperatures <=20°C are for basement quarters.

ENG-13 www.comedes.com
Maintenance
The Comedes Demecto 70 is largely maintenance-free. To maintain the level of
dehumidifying efficiency you need to clean the filter at least once a month, or more
often if necessary.
To do this, switch off the device, pull the power cable and remove the
water tank at the back of the device. Now you can pull down the nylon filter. Rinse the
filter with warm water and allow to dry. Then you can fit it back on the device.
Check the hose used for the drainage regularly for blockages and damage. If the
hose is blocked or damaged, replace it with a new one.
