3.6 Installation and connection of components 

 
Before  starting  up  and  commissioning  the  DanX  AF  unit  it  is  important to have  installed  all 
components of the air handling unit correctly. 
 
All installation and connection work should only being carried out by trained specialists

 

or by 

people  supervised  by  authorized  staff.  It  is  the  responsibility  of  the  fitter  to  read  and 
understand this guide and other given information. 
 

 
 
3.6.1 Condense water outlet 

 
Drainage  from  the  condensate  tray  is  taking  place  through  a  connection  in  front  of  the 
inspection side through the cover panel. On AF units we will see one outlet on the exhaust 
side (negative pressure). There are two different types of water traps available. 
 
Drain trap with ball valve 
This drain trap should only be installed where there is negative pressure in the drain system 
as the ball valve will open on positive pressure. The inserted float ball prevents the intake of 
air under dry operation, where in a traditional drain trap you have to refill water to avoid air 
been  sagged  into  the  unit.  At  the  same  time  you  need  less  space  in  height  than  on  a 
traditional drain pipe. This drain trap can be used up to -900 Pa. 
 
Normal drain pipe  
The  normal  drain  pipe  with  screw  cap  for  filling  with  water  and  check  can  be  used  for 
negative and positive pressure. The length of the pipe can be calculated the following way. 
 
Negative pressure 

: H1 = ∆p + 50 mm 

H2 = 

∆p / 2 + 50 mm 

 
∆p = pressure in mm WS (100 Pa = 10 mm WS) 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

3.6.2 Fresh air damper 

 
The  damper  motor  is  installed  and  pre  wired  and  connected  to  the  terminal  strip  of the  AF 
unit. For 

further information’s see the electrical diagram of the unit.
