Refer to
Figure 5
. The Model NR-10 Floor-
Mount 10 Gallon Nitrogen Receiver is a steel tank for receiving and storing nitrogen from the Model SC-W assembly,
and minimizes the Model SC-W assembly compressor runtime by providing a reservoir of nitrogen for the sprinkler
system. The nitrogen receiver is designed to be floor-mounted, when wall- or riser-mount of a nitrogen receiver is not
practical. The tank is manufactured to ASME Section VIII Division I. The device includes an inlet fitting at the top, an
outlet fitting on the side, and a manual drain valve at the bottom. The device is required to be mounted vertically as
shown, so that water drainage can be accomplished.
