OTE: Do not use termination fittings made of rubber or similar compounds as the brine solution and in-sump atmosphere may cause deterioration. The valve stem should be removed from the Shrader valve in the tank sump (low point) for filling. If the layout is such that there are two or more legs coming off the line from the tank, each leading to multiple dispensers, care must be taken to remove as much air as possible. If filling with gravity flow or by pressure, the last valve stem in each leg should initially be removed to provide a vent for air as the line fills. Note: if the piping leg terminates with a reservoir (lower leg shown in Figure 4), do not remove any valve stems in the line at this point. If the leg "dead ends" (upper leg in Figure 4), remove the valve stem until the line is full, then replace it. SLast Sump in Branch Leg. Remove Valve Stem until full, "'Z _ Then Replace.

Figure 4 Allow brine to flow or be pumped into the containment volume until it flows into the reservoir and fills it to the center of the high and low level alarm positions in the vertical riser pipe. For piping layouts in a parallel pattern, after filling to the level described above, keep the brine source connected to the Shrader valve at the tank sump. Beginning at the intermediate termination sleeve nearest the tank sump in each leg (See Figure 5), temporarily remove the valve stem. This will allow air to vent from the branch and brine to fill it from the main line to the termination sleeve. When the air is purged, brine will begin to flow out of the Shrader valve. Replace the valve stem and proceed to the next intermediate sump and termination sleeve in that line. Continue until all lines and branches are filled. Check the reservoir to make sure the brine level stays at or slightly above middle of the alarm levels. The filling of the small branches is to be done from the brine source, rather than from the flow coming out of the reservoir.
