The wheels are positioned such that the machine can be pulled upstairs without damage to the cabinet or
stairs.
1.6 Stacking
Max. two dehumidifiers should be stacked on top of eachother. Press the handle of the lower dehumidifier
to the bottom before stacking. The handle then fits a notch on the upper dehumidifier.
1.7 Operationprinciple
The following describes the air flow through the dehumidifier:
1. A fan draws in humid air through a filter to the dehumidifier
2. The air is cooled down and humidity/water drops are led down to the water tank
3. The air is reheated by the operation of the dehumidifier (approx. increase in temperature is +5 °C)
3 Introduction 190TEN-1071-C1304
Dehumidifier MKD-series
Due to the repeated air circulation thr
whereby achieving rapid but gentle d
sensor is connected.
1.8 Maincomponents

2Installation
Place the dehumidifier
■ in the middle of a room if possible to ensure good air circulation
■ where air can be sucked in freely through the filter and blownout on the opposite side
■ with a minimum distance on the supply air side from a wall of about 600 mm. The minimum distance on
the dry air side should be 3 m
■ away from any source of heat e.g. a radiator
In addition, ensure that windows and doors are closed in the room to be dehumidified.

Dehumidifier MKD-series
2.2 Connectionofhumidistat
The connection socket for the humidistat is located at the power cable entry.
The humidistat shall be mounted 1–1.5 m. above the floor and positioned so that it is not exposed directly to
dry air from the unit or incoming moist air from opening and closing doors. It may not be placed close to a
heat source or so that it is exposed to direct sunlight. The humidistat shall be a single stage humidistat and
connected so that the controlling circuit closes as relative humidity increases. The connecting cable shall be
screened and have copper conductors with a minimum cross-section area of 2 x 0.75 mm2.
2.3 Remotesignals
If an external alarm or run signal is required use terminal 24 and 25 which are connected by an electronic
relay. The run signal to be connected at terminal 22 and 23. If an error occurs there is no longer connection
and the alarm will start. Max 24V DC and 1,5mA.
