3.4) REPLACING GLASS GAUGE & RUBBER WASHERS OR
GLASS PACKINGS
The Sight Glass (#10) gives the operator the ability to easily monitor the actual water level
inside the chamber. If the Sight Glass (#10) gets clogged or is no longer functional, it can be very
difficult to troubleshoot a problem.
3.4.1) BRASS SIGHT GLASS (STANDARD)
GLASS GAUGE and RUBBER WASHERS
MUST be replaced EVERY SIX MONTHS
INSTALLATION:
Only properly trained personnel should install and
maintain water gauge glass and connections.
Remember to wear safety gloves and glasses
during installation. Before installing, make sure
all parts are free of chips and debris.
1. Uninstall GUARD RODS, GLASS GAUGE, and
RUBBER WASHERS. (You may need to rotate one of the
GAUGE FITTINGS to remove GLASS GAUGE)
2. Slip a new RUBBER WASHER on the new GLASS
GAUGE about an inch from the bottom.
3. Now slip the following items through the top of GLASS
GAUGE in the following order:
• FRICTION WASHER
• GLASS PACKING NUT (facing down)
• GLASS PACKING NUT (facing up)
• FRICTION WASHER
• RUBBER WASHER (inch down from top)
4. Gently insert GLASS GAUGE into GAUGE FITTINGS.
You may need to rotate GAUGE FITTINGS until
vertically aligned, after GLASS GAUGE is in.
5. Carefully raise GLASS GAUGE about 1/16” from bottom
and slide lower RUBBER WASHER down until it makes
contact with the BOTTOM GAUGE FITTING. (DO NOT
allow GLASS GAUGE to remain in contact with any metal)
6. Carefully slide upper RUBBER WASHER 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.
8. Reinstall GUARD RODS.
