INSTALLATION INSTRUCTIONS
The installation information listed in this section deals with the
limitations and parameters of this pre-engineered system. Those
individuals responsible for the installation of the R-102 system
must be trained and hold a current ANSUL certificate in an
R-102 training program.
Before attempting any installation, the entire system design
must have been determined including: Nozzle Placement,
Tank Quantity, Actuation and Expellant Gas Piping, Distribution
Piping, and Detection System Requirements and an installation
sketch should be completed.
INSTALLING RELEASE ASSEMBLY COMPONENTS
For successful system performance, the regulated release assem-
bly, regulated actuator assembly(ies), and tank-enclosure(s) or
tank-bracket assembly(ies) used must be located in areas where
the air temperature will not fall below 32 °F (0 °C) or exceed
130 °F (54 °C). The R-102 system is limited to interior applica-
tions only. Also, the components must be arranged to conform to
the actuation and expellant gas line, and the distribution piping
guidelines noted in “System Design.”
1.
CAUTION
Use only an AUTOMAN Regulated Release assembly or
OEM Release/Bracket Assembly. The regulator in this
assembly is specifically designed to allow a regulated flow
of expellant gas into the agent tank(s). Absence of this
regulator could cause the tank(s) to rupture or create an
improper system discharge.
Mount the regulated release assembly, OEM Release
Assembly, and each regulated actuator assembly required
by completing the following steps: See Figures 5-1, 5-2, and
5-3.
a. Select a rigid surface for mounting the enclosure. The
mounting locations must allow the regulated release
assembly and the regulated actuator assembly(ies) to
be within the limitation of the actuation and expellant gas
line lengths and must be able to support the weight of
the assembly(ies). When the OEM Release Assembly is
mounted inside a cabinet, clearances shall be provided
for unrestricted movement of the release assembly
components within the closed cabinet.
b. Detach cover from the enclosure. Remove agent tank
from enclosure and the expellant gas line hose from the
tank/adaptor assembly.
c. Secure enclosure box to selected mounting location
using the four mounting holes. Use appropriate type of
fasteners depending on the mounting surface.
d. When mounting a 6 gallon manifolded system (or a 6
gallon individual piped system) it is critical that each
mounting box is located as shown in Figure 5-3. There
must be a 5/16 in. (7.9 mm) space between each box.
Less than 5/16 in. (7.9 mm) will cause interference with
the covers, and more than 5/16 in. (7.9 mm) will cause a
gap between the two hose grommets which will expose
the hose to possible tampering or damage.
Remove the 7/8 in. (22 mm) knockout on the left side
of the AUTOMAN release box and remove the 1 in. (25
mm) knockout on the right side of the tank-enclosure
box. Install grommets in each (use ANSUL hose/grommet
package (Part No. 418511)). Remove 1/4 in. plug from
back side of R-102 regulator and install fixed end of
secondary expellant gas hose (included in hose/grommet
package in 1/4 in. regulator outlet and wrench tighten.
If not already done, mount both boxes to a rigid surface
using appropriate fasteners.
Fill tanks per instructions listed in Steps 3 and 4 on
Page 5-3.
Next, route hose through grommets and wrench tighten
into 1/4 in. inlet of the adaptor on the tank in the tank/
enclosure assembly. Also install hose to tank adaptor in
regulated release and wrench tighten. See Figure 4-135
in “System Design” for details of hose routing.
