SUCTION AND DISCHARGE TUBE
BRAZING
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 tting. (See Figure 9.)
• To connect:
– Recommended brazing materials: silfos with
minimum 5% silver or silver braze material with
ux.
– Reinsert tube into tting.
– 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 ow 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.
