Compliant Scroll compressors have copper plated 
steel suction and discharge tubes.  These tubes are far 
more rugged and less prone to leaks than copper tubes 
used on other compressors.  Due to different thermal 
properties of steel and copper, brazing procedures may 
have to be changed from those commonly used.
  To disconnect:  heat joint Areas 2 and 3 slowly and 
uniformly until braze material softens and the tube 
can be pulled out of suction fitting.  (See Figure 9.)
  To connect:
 
–  Recommended brazing materials:  silfos with  
 
minimum 5% silver or silver braze material with  
  flux.
  –  Reinsert tube into fitting.
 
–  Heat tube uniformly in Area 1 moving slowly to  
 
Area 2.  When joint reaches brazing  
 
 
temperature, apply brazing material.  (See  
 
Figure 9)
 
–  Heat joint uniformly around the circumference  
  to flow braze material completely around the  
 joint.
 
–  Slowly move torch into Area 3 to draw braze  
 
material into joint.  (See Figure 9.)
 – 
Do not overheat joint.
