area greater than 4 m². Check if there are any local regulations that you
have to observe when installing or storing the device.
•The device must be installed in a room without a permanently active ignition
source (for example: open fire, a gas device or electric air-heater in operation).
•Keep the ventilation openings free of foreign objects during operation.

Product- and functional description
Introduction: This section will give you a description of the machines type KT 580
and the functions:
Important: The length of the 100 mm connection hoses (accessories) for the model
KT 580 may be not more than 7.6 metres per tube.
Principles of The following describes the air flow
operation: through the dehumidifier:
The air flow through the
dehumidifier.
A fan draws in humid air through a
filter to the dehumidifier
The air is cooled down and
humidity/water drops are led down
to the water tank
The air is re-heated by e.g. the
operation of the dehumidifier (approx.
increase in temperature is + 5 °C)
Due to the repeated air circulation through the dehumidifiers, the air humidity is
continuously reduced whereby achieving rapid, but gentle drying.
The dehumidifier can be operated continuously or controlled by a built-in hygrostat.

Product- and functional description
Hose
connection: With two hoses connected to the outlets (2 x 100 mm Ø):
Dry, warm air can be directed for example under a floor.
Hans Wilms GmbH & Co. KG recommends maximum 7.6 metres
hose per air outlet.
Heating
element: The KT 580 has a built-in heating element with 1 kW. If the dehumidification process
should be speeded up, the heating element can be activated, and this increases the
outlet temperature. See manual, page 9 for Activation of the heating element.
Water tank: Water is collected in the water tank. Alternatively, you can also setup the dehumidifier for
permanent drainage with the adapter for hose connection (accessories, see page 17).
When the water tank is full, the dehumidifiers shut off automatically.
Emptying of the water tank, see manual, page 16.
Operation of the unit is not possible once the water tank is removed.
