IMPORTANT NOTE:
Read all warnings and instruc-
tions before performing installation or maintenance.
Safety glasses and gloves should be worn at all times
when working with or examining water gauge glass
and connections. Pressure in generator to be at zero
before proceeding. Improper installation or mainte-
nance of gauge glass and connections can cause imme-
diate or delayed breakage resulting in bodily injury
and/or property damage.
1.
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).
2.
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 fit-
tings are threaded into the tappings the same num-
ber of turns (distance A= distance B).
3.
Remove glass packing nut, friction washer (or pack-
ing gland, depending upon the model), 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.
4.
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 fitting clockwise
until vertically aligned with the bottom gauge, then
insert glass into bottom fitting until glass bottoms
out on the shoulder inside the bottom fitting.
5.
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!
6.
Carefully slide upper glass packing up as far as possible.
7.
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 lightly, a quarter turn at a time, checking for leakage after each turn.
IMPORTANT NOTE:

Safety glasses and gloves should be worn at all times when working with
or examining water gauge glass and connections.
