Water Gauge & 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 fit-
ting (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 point-
ing 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 fit-
tings, 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 fit-
ting, gently rotate the top gauge fit-
ting 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 pack-
ing up as far as possible.
10) Hand tighten both glass pack-
ing 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.
Gauge glass valves utilize automat-
ic ball checks to help prevent injury
in case of glass breakage.
Warning
Improper installation or mainte-
nance of gauge glass and con-
nections can cause immediate or
delayed breakage resulting in
bodily injury and/or property
damage.
