Attach the Removable Elements
The five longest elements on each boom assembly (the last five from the bottom)
are removed for shipping, and should be re-attached during assembly inside the
chamber.
The elements and the location on the boom assembly where they attach are
marked with the numbers 1, 2, 3, 4, and 5.
Do not cross thread the connection or permanent damage to
the element or boom could occur.
1. Match the number 1 on the element with the number 1 on the boom.
The end of the element and the connector on the boom are threaded;
rotate the element into the connector, and then hand tighten.
2. Repeat step 1 for elements marked 2, 3, 4, and 5, attaching them to the
corresponding locations on the boom marked 2, 3, 4, and 5.
3. Repeat step 1 and step 2 for each boom assembly.
