1.General advice 

 

You have bought an air dryer made by AERIAL thus deciding for a proven quality 
product "Made in Germany". If f there are any questions, you will find some advice 
in this manual how to eliminate such difficulties as quickly as possible. 
 

ATTENTION:

 

Immediately after receipt, you should check your air dryer for transport damage! In 
the case of damage, you should inform the forwarding agent, parcel service, post 
office etc. accordingly upon receipt, and make a note of it on the forwarding 
documents! 

 

If a transport damage should be noticed after unpacking the equipment, please 
contact immediately your respective seller or specialized dealer.  
 
Before putting your air dryer into operation for the very first time, these instructions 
for operation should be studied very thoroughly. Thus, you can make sure that this 
appliance will operate perfectly for a long period of time saving yourselves 
unnecessary repairs and expenses. 
 
In the case of malfunction disconnect your appliance and ensure that it is not 
connected again by taking the mains plug out of the socket. 
 
Please, keep the device wrapping in order to be able to send the device safe for 
guarantee repair. In order to save space you open simply the adhesive tape with a 
knife and you fold the carton. 
 
 

2.Mode of functioning 

 

The AD-air dryer is constructed exclusively for air drying in closed rooms. That 
dehumidifier can prevent the formation of condensation, eliminate too high air 
humidity and hold a specific air humidity constant. The time which the dryer requires 
in order to achieve a specific humidity depends essentially on the environmental 
conditions. The attainable humidity value is equally dependent on the environmental 
conditions. 
The AD-dehumidifier works according to the condensation principle with heat 
recovery. The fan (shown indicatively below) suck the moist air through a cool 
register (evaporator). The air becomes so far chilled under the point of 
condensation here, that the moist air condense as water and flows into the water-
collecting tank. The chilled and dried air is warmed up at the condenser again. 
Through the heat pump effect, the outlet air is some degrees warmer than the 
sucked room air. Useful energy can conducted up to 3-fold of the electrical power 
consumption. The absolute moisture of air is lowered continuously by the 
continuous circulation of the room air through the device. The surplus moisture is 
removed safely and efficiently.
