KRS-100 Nitrogen Releasing System
and without having to use a single extinguishing system
which could be difficult to install within its piping limitations.
Whenever two or more KRS cylinders are used, each must
be isolated from the others by a check valve (P/N 259404).
The purpose of the check valves is to prevent loss of pres-
sure during discharge on one cylinder in the event that one
of the cylinders is disconnected.

Location
The KRS-100 cylinder and actuator valve assembly shall
be located where the temperature is between -40°F (-40°C)
and 120°F (48.9°C). The entire assembly, cylinder, actua-
tor, and control head must be protected from rain, snow, or
other inclement weather conditions by a suitable total or
partial enclosure. They all must be mounted in such a way
that no part of the assembly stands in water or other liquid.
