4. Install the gland followers, polycarbonate sleeve, Size 7 (1/2") and
larger, gland rings, and packing on the tube.
Note: Both hat gaskets are purposely tight fitting and can be installed
more easily from the inlet (narrower) end of the tube. The inlet (smaller)
gasket is often difficult to place over the glass tube. A suggested
method is to place the hat gasket in the gland ring on a flat surface
prior to installation and carefully work the tube through the gasket and
ring. This will stretch the gasket enough that it can be removed and
reassemble on the tube in the proper order. Immersing the hat gaskets
in warm water will further increase their elasticity. If the outlet gasket on
larger tubes in unable to be moved into position when being driven by
the packing ring, a small amount of silicone lubricant may be used.
5. Install the end fittings onto the tube and packing assembly. Insure that
the outlet (large) end of the tube fits flush against the tube seat gasket
in the outlet (top) end fitting.
6. Rotate the tube so that the zero line or scale is in the proper, legible
position.
7. Secure the outlet gland ring and follower with the four gland bolts. Do
not tighten the bolts more than finger tight at this time.
8. Install the inlet end fitting on the tube. Secure the inlet gland ring and
follower with the four gland bolts. Do not tighten the bolts more than
finger-tight at this time.
9. Install the scale side plate (if applicable). Secure with the four side plate
bolts.
10.Install the second side plate. Secure with the four side plate bolts.
11.Tighten the gland bolts on the outlet fitting to prevent the tube from
pulling away from the seating gasket.
12.Perform final alignment of the detachable scale (if applicable) with the
zero line on the tube.
13.Install the windows and window frames. Secure the window and frame
assemblies with the four window frame bolts. Tighten the bolts to one
quarter turn past snug.
