5.  Connecting a hose 

 
5.1. The connection point for the drain hose is located on the right-hand side of the condensation tank (see diagram 

below). First remove the black sealing plug there. 

5.2. It is best to use a ½ inch plastic hose and pass it through the hole provided on the side (alternatively the lower 

hole) and then put the hose over the plastic tap provided for this purpose.  

5.3. Make sure that it fits properly. For safety, we recommend fixing the hose with a clamp/clip ! 
5.4. Make sure that the hose always has a slight slope ! 
 

 

 

 
 

6.  Cleaning 
 

6.1 Cleaning the housing 

 

 

Please disconnect the mains plug before cleaning the construction dryer. 

 

Only use mild cleaning agents to clean your construction dryer. 

 

NEVER spray your building dryer (e.g. with water or similar). 

 

6.2 Cleaning the air filter screen and the cooling fins 

 

The air filter screen at the front of the air intake filters lint, hair and coarse construction dust. Furthermore, the air 
filter ensures that less dust is deposited on the cooling fins, thus ensuring higher efficiency. Too much dust and dirt 
in the filter sieve or on the cooling fins reduces the dehumidification performance and can lead to a loss of 
efficiency in the 
In the worst case, this can even cause damage to your construction dryer, so the following applies in the case of 
coarse soiling or in rooms with a lot of construction dust: clean the air filter screen and also the evaporator unit 
regularly! 

 

 

Clean the filter whenever it can be assumed that the air intake is reduced by the dirty fan screen or that dirt and 
dust has been deposited on the cooling fins. (This can sometimes even be the case daily on dusty construction 
sites. ) 

 

Switch off the unit and disconnect the mains plug ! 

 

Open the front door where the air filter screen is attached as follows: Reach under the top two metal slats and 
open the front panel by gently jerking it away from the unit. 

 

The air filter screen is attached to the inside of the front fairing. Now remove the retaining rods of the air filter 
screen by passing the retaining rods through the upper and outer holes of the outer frame. 

 

Now you can remove the air filter screen. Wash the dirty sieve well under lukewarm water or vacuum it out 
thoroughly with a hoover.
