4-3-1 Installing Vacuum and Material Tubing
Use the following as a general reference when installing your system:
• Refer to the assembly prints often.
• Support overhead tubing about every ten (10) feet (3 m) with straps, pipe
hangers, or brackets. Keep the coupled joints rigid to avoid vacuum or
material leaks from tubing movement or misalignment.
• Cut all tube ends square, and chamfer internal edges smooth. Make sure
that the tube ends butt together inside the coupler.
• Tighten coupler nuts with a wrench to help provide a vacuum and
material-tight seal and proper contact of the internal grounding strip.
• If you must cut bends, do so on the straight section at either end, and
leave enough straight length for adequate insertion in the coupler.
• Make sure that material flow is in the direction of the arrows on flexible
material hose.
