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.
