Space-Ray FUSION Series Installation & Operation Instructions page 17

See typical assembly overview (Section 0 for typical complete assembly. Assemble additional extension sections
as required for all systems. (See Sections 7.0), and 0 for typical layout details.)
Join the tube sections together and secure with tube couplings as described below:
1. Place the compression coupling over the end of the tube.
2. Use the small hole at the centerline of the coupling to check that the coupling is inserted correctly.
3. Partially tighten the bolt nearest the end of the tube (approximately half closed).
4. Slide the next tube into the coupling.
5. Make sure both tube ends are butted together.
6. Finish tightening both bolts to 40-60 ft.lbs. torque to ensure a complete seal.
7. Use the two Self-drilling screws through the pre-punched holes to secure the tubes in the coupling.
The following coupling tightening instructions MUST be followed properly
to ensure the integrity of the tube connections. Two #10 self-drilling
screws MUST be installed at every coupling as shown in the instructions
below. Failure to do so may result in serious injury or property damage.
