PENBERTHY SERIES U FLAT GLASS GAGES
INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS

8.3 Reassembly

If all glass seating surfaces are found to be
within the tolerances described in the previous
section, proceed to obtain new glass, gaskets
and cushions, and proceed to reassemble
as follows (refer to exploded parts view in
Section 11 if needed):
1. Clean threads on cap screws, studs and
nuts to remove all paint, rust and scale.
Apply a light coat of oil to the threads.
2. Lay chamber flat on bench with gasket slots
facing up. Lay out covers along the bench,
side by side, with the liquid chamber. Use
chamber to space covers and line them up
with vision slots.
3. Install gasket in place on liquid chamber.
When using a gasket with a retainer, the
gasket should be installed with the retainer
side away from the chamber.
WARNING
Separate installation instructions are supplied
with replacement glass. All instructions supplied
with the glass must be followed, as there are
precautions to be taken when handling gage
glass. Among the precautions is avoidance of
bumping or sliding glass against any surface and
inspection of individual pieces. Failure to follow
any of the replacement gage glass installation
instructions could result in glass breakage with
resulting sudden release of pressure, severe
personal injury or property damage.
4. Install rubber band around glass, then
place glass centered on gasket.
5. Install cushion centered on glass.
6. Install cover in place being careful to
maintain components alignment inside.
7. Secure the cover to the liquid chamber with
the corner cap screws. The cap screws
should only be snugged down enough to
maintain the cover positioning.
8. If the gage is a multiple section, complete
the gasket, glass, cushion and cover
assembly for the remaining sections per
instructions 3 through 7 above.
9. Rotate the liquid chamber 180° on the
bench so as to expose the glass pocket on
the opposite side of the liquid chamber.
10. Install the gasket, glass, cushion and cover
for each section per instructions 3 through 7
above.
11. Turn the gage on its side on the bench.
Install the nuts on one end of the studs and
insert studs into all remaining holes in the
covers for each section.
12. Install nameplate, washer and nuts to studs
on the opposite side of the gage. Tighten
nuts with fingers. Using a torque wrench,
tighten cap screws and nuts in 5 ft·lb (7 Nm)
increments, following the sequence in
Figure 1 until the torque values shown in
Table 2 are reached.
Note: depending on gage size there may be
less bolting than shown in Figure 1. Start at
the center and follow 'Z' pattern outward to the
limit of bolting on a specific gage.
Refer to Section 5 for installation and Section 6
for operation of liquid level gage when
returning to service.

9 DISPOSAL AT END OF USEFUL LIFE

Penberthy gages are used in a variety of fluid
applications. By following the appropriate
federal and industry regulations, the user
must determine the extent of preparation
and treatment the gage must incur before its
disposal. A Material Safety Data Sheet (MSDS)
may be required before disposal services
accept certain components.
Metal, glass and polymers should be recycled
whenever possible. Refer to order and
applicable technical data sheets for materials
of construction.
