Sussman ES Installation, Operation And Maintenance Manual - page 20
IMPORTANT NOTE: Read all warnings and instructions
before performing installation or maintenance. Safety glass-
es 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.
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 posi-
tion).
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= distance 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 fit-
ting. 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 1/16" and slide lower glass
packing down until the glass packing contacts the lower
gauge fitting. DO NOT allow the glass to remain in con-
tact 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 lightly, a quarter turn at a time, checking
for leakage after each turn.
IMPORTANT NOTE:
Read all warnings and instructions before performing instal-
lation or maintenance.
Safety glasses and gloves
should be worn at all times when working
with or examining water gauge glass and con-
nections.
Pressure in generator to be at zero before pro-
ceeding.
Improper installation or maintenance of gauge
glass and connections can cause
immediate or delayed breakage resulting in
bodily injury and/or property damage.
