Water Gauge & Gauge Glass Installation
26
IMPORTANT:
Only properly trained personnel should
install and maintain water gauge glass and connections.
Pressure in generator must be at zero before proceeding.
Remember to wear safety gloves and glasses during instal-
lation. Before installing, make sure all parts are free of chips
and debris.
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 fittings are threaded into
the tappings the same number of turns (distance A= dis-
tance B).
3. Remove glass packing nut, friction washer (or packing
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 fitting, 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 1/1611 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 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.
IMPORTANT:
Read all warnings and instructions 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 maintenance of gauge glass and connections can cause immediate or delayed
breakage resulting in bodily injury and/or property damage.
