Water Gauge & Gauge Glass Installation - FULTON FB-L 012 Installation Operation And Care

Water Gauge &
Gauge Glass Installation
NOTE
Only properly trained personnel should
install and maintain water gauge glass
and connections. Wear safety glasses
during installation. Before installing,
make sure all parts are free of chips and
debris.
NOTE
Keep gauge glass in original packaging
until ready to install.
1. Verify the proper gauge has been supplied.
2. Examine the gauge glass and packings
carefully for damage before installation.
Do not use the glass if it contains any
scratches, chips, or any other visible signs
of damage.
3. Do not subject the gauge glass to bending
or torsional stresses.
4. Apply Teflon tape or pipe dope to pipe
threads. Install top gauge fitting (fitting
without a drain valve) into the uppermost
tapping. Wrench tighten the fitting until it
is snug and the glass outlet is pointing at
five o'clock (about 1/8 turn from its final
downward vertical position).
5. Install the bottom gauge fitting (the fitting
with a drain valve) until it is snug and the
glass outlet is pointing directly upward.
Verify top and bottom fittings are threaded
into the tappings the same number of
turns (distance A=distance B).
6. Remove glass packing nut, friction washer
and glass packing from the fittings, and
place them, in the same order, on to both
ends of the gauge glass. Push both
packings about an inch up the gauge
glass.
7. Gently insert one end of the glass into the
top gauge fitting. Keeping the glass inside
the top fitting, gently rotate the top gauge
fitting clockwise until vertically aligned with
the bottom gauge fitting, then inset glass
into bottom fitting until glass bottoms out
on the shoulder inside the bottom fitting.
8. Carefully raise glass about 1/16" and slide
lower glass packing down until the glass
packing contacts the lower gauge fitting.
DO NOT allow the glass to remain in
contact with any metal!
9. Carefully slide upper glass packing up as
far as possible.
10. Hand tighten both glass packing nuts,
then tighten 1/2 turn more by wrench.
Tighten only enough to prevent leakage.
Do not over tighten! If any leakage should
occur, tighten slightly, a quarter turn at a
time, checking for leakage after each turn.
