(not 

included in the outfit of the A/C unit) 

a)

 

Connect the unit to the manifold (use 

HP hose and quick coupling) 

b)

 

Mount reducer on N bottle and connect 
to the manifold using the yellow hose 

Forming gas bottle with pres- 
sure reducer (use yellow hose) 

coupling 

c)

 

Connect the manifold to the A/C system 

using the included quick coupling 

d)

 

Reduce pressure to 8-10 Bar and open 
the tap and the quick couplings (on the 
vehicle and on the manifold 

Adjust test time (example: for a medium
