Assembling
1. Mark the fixing positions (A) on the new Tube following the Tube Layout Chart.
<Note>
・ The starting position of measuring is the edge of the Fitting (position B).
・ Put the Tube on the table and make it "naturally" straight to mark on the right positions; do not pull it
out by force or the Tube may be stretched and the marking positions may shift.
2.
Remove the Round Tube Holder (1), the Middle Tube (2) and the Spiral 258 (3) from the old Tube.
3.
Grip the new Tube with the Middle Tube (2) and the Round Tube Holder (1).
<Note> Confirm that the slit of the Middle Tube (2) should be in the center of the open space of the
Round Tube Holder (1).
4.
Mount the Spiral 258 (3) on the Tube.
<Note> Wrap the Spiral 258 (3) over the Middle Tube (2) and prevent its edge from touching the Tube
