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 gener-
ator to be at zero before proceeding. Improper instal-
lation 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 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= 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 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 1/16" 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
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.
