Connect condensate drain hose to 

suitable container or gravity drain.

Which automatically starts and stops the 

machines compressor when pre-set 

humidity levels are reached.   

Many dehumidifying applications require 

humidity to be controlled at set relative 

humidity levels (RH) to avoid shrinkage of 

materials, cracking plaster, furniture etc.

The FD40 has been designed taking this into 

account and thanks to the external 

humidistat you will be able to control the 

humidity levels as desired in the room.

Switch on machine via rotary switch. 

Position 0 : Off

Position 1 : 230 volt.

Position 2 : 110 volt.

ENSURE THE VOLTAGE SELECTOR SWITCH 

LOCKING PLATE IS IN THE CORRECT POSITION.

Disconnect from electrical supply when not in use.

Fig 5 :

 

The condensate pump is close coupled electrically 

to the machine via a built in auxiliary connection.  

Up to 20 metres  of flexible drain hose can then be routed  

to a suitable drain point.

The FD 40 can be supplied with a separate 

condensate pump.

If the Dehumidifier is to be used in an unoccupied 

building where a gravity drain is not practical and 

to avoid the need to regularly empty a container. 

(Time scales can vary depending on humidity 

levels).
