General warnings
Warning:
The dehumidifiers contain a flammable refrigerant. Take following precautions in order
to avoid any danger:
Point of awareness:
•Be aware that refrigerants may not contain an odour.
Location requirement (installation and storage):
•The appliance shall be installed, operated and stored in a room with a floor area
larger than 4m2. Check if there are any local regulations, you must comply to,
when installing or storing the appliance.
•The appliance shall be stored in a room without continuously operating ignition
sources (for example: open flames, an operating gas appliance or an operating
electric heater.)
•Keep the ventilation openings clear of obstruction during operation.
Actions to avoid (operation and handling):
•Be especially careful when handling the unit, not to cause any damage that may
result in leakage of the cooling circuit.
•Do not use means to accelerate the defrosting process or to clean, other than
those recommended by the manufacturer.
•Do not pierce or burn.
In case of fire:
•Toxic fumes may occur in the event of fire. Thus you must leave the room as
quick as possible in the case of fire.

Setup and user guide
Product and function descriptions
Introduction
This section provides a product description of the CDT 30S/40S MKIII, plus a description
of its functionality.
How it works
Air flow through the dehumidifier:
How the air changes as it passes
through the dehumidifier:
The fan draws humid air through a fil-
ter inside the dehumidifier.

The air is cooled, causing the moisture
content to condense into drops of wa-
ter, which are collected in the water
container.

The air is reheated using heat from the
dehumidifier's operation (temperature
increase of approx. +5 °C), and the
option of further heating using the in-
tegrated heating element.
As the air is repeatedly circulated through the dehumidifier, its moisture content is re-
peatedly reduced, resulting in rapid, gentle drying. The dehumidifier can run constantly,
or be controlled by a built-in hygrostat.

Product and function descriptions, cont.
Ducting connections
With two hoses (2 x 100 mm dia.) on the exhaust, dry, hot air can be passed under a
surface such as a floor.
Dantherm recommends connection of max. 5 metres of flexible ducting per connection
spigot.
Heating element
CDT 30S/40S has one 1 kW integrated heating element. When the element is active, the
dehumidification process is accelerated. See page 11 of the user guide for heating ele-
ment operation.
Water container
Condensate water is collected in the water container or it can be piped to a drain via a
hose spigot (optional accessory).
The dehumidifier cuts out automatically when the container is full. See the user guide
for emptying the water container. The dehumidifier cannot operate when the container
is removed.

Preparation and transportation guide, cont.
Position
Position the dehumidifier where there is plenty of air circulation around it, with mini-
mum 60 cm of clearance on the air intake side, and 3 meters of clearance on the ex-
haust side if no flexible ducts are attached. Remember also:
•To keep ventilation openings clear of obstruction during operation.
Location
requirements
Since the dehumidifiers contain a flammable refrigerant following location requirements
must be fulfilled:
•The appliance shall be installed, operated and
stored in a room with a floor area larger than
4m2. Check if there are any local regulations,
you must comply to, when installing or storing
the appliance.
•The appliance shall be stored in a well-ventilated area, where the room size
corresponds to the room area of 4m2.
•The appliance shall be stored in a room without continuously operating ignition
sources (for example: open flames, an operating gas appliance or an operating
electric heater.)
Optimum operation
Ensure the room to be dehumidified is sealed, and that the machine is not located near
a heat source, such as radiators.
If flexible ducts are attached, performance will be significantly impaired if they exceed 5
metres in length.
Electrical connection
The machine comes complete with a 3.5m power cord, and can be connected to any 230
V, 50 Hz socket with a 10-16A fuse.
If the plug has 3 pins incl. PE-connection a plug adapter (accessory –item no. 396249)
has to be used.
Warning: If the supply cord is damaged, it must be replaced by the manufacturer, its
service agent or similarly qualified persons in order to avoid a hazard.
