Installation
Water Gauge and Gauge
Glass Installation
Instructions
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.
11. Install the protective guard, and utilize
automatic ball checks where necessary
to help prevent injury in case of glass
breakage.
WARNING
Improper installation or maintenance of
gauge glass and connections can cause
immediate or delayed breakage resulting
in bodily injury and/or property damage.
