Manual 2100-353Page 20SUCTION AND DISCHARGE TUBEBRAZINGCompliant Scroll compressors have copper plated steelsuction and discharge tubes. These tubes are far morerugged and less prone to leaks than copper tubes usedon other compressors. Due to different thermalproperties of steel and copper, brazing procedures mayhave to be changed from those commonly used.• To disconnect: heat joint Areas 2 and 3 slowly anduniformly until braze material softens and the tubecan be pulled out of suction fitting. (See Figure 10.)• To connect:– Recommended brazing materials: silfos withminimum 5% silver or silver braze material withflux.– Reinsert tube into fitting.– Heat tube uniformly in Area 1 moving slowly toArea 2. When joint reaches brazingtemperature, apply brazing material. (SeeFigure 11)– Heat joint uniformly around the circumferenceto flow braze material completely around thejoint.– Slowly move torch into Area 3 to draw brazematerial into joint. (See Figure 11.)– Do not overheat joint.MIS-1179FIGURE 11BRAZING DIAGRAMTABLE 13INDOOR BLOWER PERFOMANCEnIPSEH 2 O3A4211P 2A0311P 2A6311P 3A2411P 2A8411P 1A0601P/yrD teW /yrD teW /yrD teW /yrD teW /yrD teW /yrD teW0.0 /5201 069 /0531 0121 /5641 5731 /0561 5261 /0591 0291 /0581 05811.0 /539 078 /0031 0611 /0341 0431 /0551 5251 /0681 0381 /0081 08712.0 /568 008 /0421 0011 /5831 5921 /5341 0041 /0871 0571 /5271 00713.0 /538 077 /5711 5301 /0431 0521 /0431 0131 /0861 0661 /0661 52614.0 /008 537 /0211 089 /5721 5811 /0321 0121 /0851 0551 /0851 04515.0 /057 586 /0501 019 /0911 0011 /0211 0011 /0051 0841 /0051 5741
