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 fitting. (See Figure 10.)

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 11)

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 11.)

Do not overheat joint.
