Appendix I: Connecting glycol water duct with PE connector 

-

 

If  the  ends  of  the  ducts  are  not  completely  perpendicular,  cut  them  off  perpendicular  without 
contaminating the inside of the duct. Also remove burrs from the duct without contaminating the inside 
of the duct  

-

 

Unscrew the coupling nut so 75% of the thread is visible. Do not remove the coupling nut completely. 

 

-

 

Measure the length of the top of the coupling to the fender and draw this point on the PE duct. 

 

 

-

 

Push the PE duct in the coupling up to the fender, so the previously made mark coincides with the green  head. To 
make the assemblation easier, the end of the duct can be wetted or lubricated with a KIWA approved lubricant. Screw 
the coupling nuts by hand using enough force. Make sure you do not turn the black side when connecting the duct to 
the unit.
