Page 3: General Product & Safety Information
1.0 General Product & Safety Information Product Information • The CRD216SS is designed to expand stiffer tubing such as nylon, polyethylene, polypropylene and Teflon tubing. With the heater off, the unit can also expand flexible tubing up to a durometer of Shore A 85 (Shore D 35), including any non-metallic braided materials. - Page 4 WARNING Avoid placing your fingers between the upper jaw block and the air cylinder mounting bracket while operating unit, sufficient pressure exists to cause personal injury. Arrows indicate pinch points WARNING • During heating and once the unit reaches operating temperature, the jaws and metallic areas around the jaws will be extremely hot.

Page 8: Setting Time Delays
Figure3.1.A.5 Setting the Time Delays • The CRD216SS expansion operation is designed to let the operator expand each piece of tubing twice. After the first expansion, the jaws will close and the operator rotates the tube 90 degrees and the jaws will automatically expand again using the sensor. This ensures that the tubing is expanded in a uniform fashion, and not deformed in only one direction. - Page 9 • Using a small Phillips drive screwdriver adjust the Time Delay relays. Figure 3.2.2 Figure 3.2.2 Adjusting the Expansion Time Pot • Figure 3.2.3 below shows the CRD216SS with the electronics cover removed, as well as the location of both time delay adjustments on the time delay relay:...
