KRS-100 Nitrogen Releasing System
The KRS-100 releasing device may be mounted either verti-
cally (plumb) with the control head or actuator at the top, or
horizontally (level), or at any angle between vertical and
horizontal.
3-1.1
POA & SVA Mounting
Prior to mounting the actuator (POA P/N 87-100012-001 or
SVA 87-120042-001) to the wet or dry chemical cylinder
valve, make certain the actuator piston is flush with the
bottom of the actuator body. If the piston is not flush, per-
form the following procedure.
3-1.1.1
POA MOUNTING
Place the unit on a flat surface and depress the valve core
while pushing down on the assembly. This will push the
piston into the body of the actuator.
3-1.1.2
SVA MOUNTING
Push the spring loaded plunger in and push in the piston.
3-1.2
Actuator Valve Assembly Mounting
The actuator valve assembly (P/N 83-100010-001) can be
mounted using the bolt holes located on the side flange of
the actuator valve body. The total assembly should be se-
cured to a surface which will support at least three times
the total assembly dead weight. Use both mounting holes
to secure the assembly.
For applications where space is tight and clearance is needed
between the control head and the wall, use a spacer (P/N 83-
100011-001) to provide the clearance. See Figure 3.
3-1.3
Tubing
Connect actuation tubing to the outlet on the KRS-100 ac-
tuator valve body. Ream and thoroughly clean all chips and
cutting oil from the inside of tubing prior to connection. All
tubing is to be securely supported, no more than ten feet
on centers. (See Table 1 for tubing limitations.)

TUBING AND FITTINGS
The KRS-100 system uses 1/4-inch O.D. copper tubing
(0.030-inch minimum wall) with flared or high-compression
tubing fittings. Tubing is also known as soft copper refrig-
eration/AC tubing. Flared fittings are SAE 45° flared brass
tube. Compression fittings are high-pressure brass tube.
The copper tubing should be cut squarely with a tubing cutter
and carefully reamed to remove all burrs before flaring with
a standard flaring tool or applying compression fittings. The
tubing need not be enclosed in conduit except where it would
otherwise be exposed within seven feet of the floor, or where
it is subject to cutting or crushing. There is no limit on bends,
