Installation 

Place CTR A on a flat and level surface, so that it cannot tip over causing damage to the machine or 
other property or injury to people.  
Connect a hose to the wet air connector to lead the wet air out of the space to be dried. The wet air 
hose should have a smooth inside and should be as short as possible, no longer than 5 metres, for 
optimum function and highest capacity. If a longer wet air hose is necessary for the installation, the 
high static pressure that the machine has is capable of dealing with a hose of up to ten metres but 
the dry air must then be restricted, which can be done without tools or instruments and yet with 
sufficient precision as follows: 
1.

 

Connect a 5 metre long hose and blow the wet air into your face to get an idea of the airflow. 

2.

 

Now connect the longer hose, up to ten metres, and restrict the dry air using the damper until the 
flow to the face feels as strong as with the shorter hose.  

In the event of problems with condensation in the wet air 
hose, if best solution of shortening the hose is not possible, 
this can be alleviated by restricting the dry air slightly, 
which leads to an increased volume of wet air. Performance 
is reduced slightly so this method must be evaluated from 
case to case. Another method is to make holes in the hose 
for the condensation and to use a container. 
 
 
Installation in brief (also see page 7, Overview, controls and connections): 

1.

 

Place the drier in a location where the wet air hose reaches the intended evacuation point. 
Ensure that it is on firm and level ground so that it cannot tip over. 

2.

 

Connect the cable to 1-phase, 230 V electrical socket fused to 10A or maximum 16A. As the 
machine is usually used in damp, wet areas, the use of a earth-fault breaker is strongly 
recommended. 

3.

 

Set the machine to Manual (Man) mode with the left button on the control panel. Check that 
the fan starts by the machine blowing air. Look into the wet air connector and check that the 
rotor rotates anti-clockwise. Hold your hand by the wet air connector and check that the wet air 
feels warm. Note that the machine needs to run a few minutes before this can be checked. 

4.

 

Connect the wet air hose and route it out through the intended evacuation point (hole in the 
wall, window, or whatever is relevant). Ensure that the hose not trapped or obstructed 
anywhere. 

5.

 

Connect any dry air hoses, turbine or whatever is relevant for the situation. Room and suction 
drying usually occurs with the 100 mm dry air connector open and the 50 mm connectors 
closed. The latter can be used to lead dry air to a separate area if necessary. During pressure 
drying with T200, connect this to a 50 mm connector. Leave the other 50 mm connector open 
but close the 100 mm connector. During pressure drying, ensure that the turbine or turbines 
total capacity (m

3

/h) does not exceed that of the drier. Regardless of the area of use, ensure 

that not all dry air connectors are closed at the same time. 

The wet air must always be evacuated via 

hose out from the space to be dried. The 

image shows room drying.
