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 pack-
aging 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 verti-
cal 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 bot-
tom fittings are threaded into the tap-
pings the same number of turns (dis-
tance 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 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 packing
nuts, then tighten 1/2 turn more by
wrench. Tighten only enough to pre-
vent 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 mainte-
nance of gauge glass and connec-
tions can cause immediate or
delayed breakage resulting in bod-
ily injury and/or property damage.
