mber 606-04, E5.8 requiring the installation to be
self draining. (Exception: white EPDM gasket is not 3-A
approved)
WARNING:

Read these instructions carefully and completely
before attempting to unpack, install or service the
rupture disc. Do not vent a rupture disc assembly to an area
where it would endanger personnel. Install the rupture disc assembly in such a way that
equipment in the area will not prevent rupture disc
from opening or be damaged by system discharge. The S3 , SR-H, SHX, AD-H TC, and Axius SC
rupture discs are designed for clean in place
applications, how ever be sure that no brush, jet
stream or any other cleaning mechanism makes
contact with the disc. Flow arrows on rupture disc tag must point in the
same direction as process flow. A baffle plate on the outlet end of vent piping does
NOT necessarily prevent potentially dangerous
discharge. Install the enclosed DANGER sign in a
conspicuous location near the zone of potential
danger. Confirm the ferrule and clamp pressure and
temperature rating prior to installing Fike rupture
disc.
The Fike S3 , SR-H, SHX, AD-H TC, and Axius SC
rupture discs are designed for use in standard sanitary
ferrules and clamps. Note that there are a variety of
sanitary ferrule standards used in industry, including
but not limited to Tri-Clover, DIN 32676, ISO 2852,
NovAseptic (NA) etc. While appearing very similar, the
ferrules are different dimensionally and the rupture disc
is not generally interchangeable between ferrule
standards. The Fike rupture discs are designed to be
compatible with the most common 13MHHM clamp,
A8647-100-X clamp and NovAseptic (NA Connect)
flanges. The A8647-100-X clamp is a modified 13MHP
clamp that allows clearance for the rupture disc tag
extension. Using clamps other than the 13MHHM
clamp or A8647-100-X clamp will result in the clamp
bottoming out on the tag extension prior to achieving
sufficient clamping force to seal the rupture disc.
INSPECTION/PREPARATION
Except where noted, rupture disc applies to both the
metal assembly and soft gasket.
A. NEW RUPTURE DISCS
WARNING: Always handle the rupture disc with
extreme caution. Nicks, dents, scratches or foreign
material may result in leakage or affect the burst
pressure. Read the rupture disc tag completely
before installing to confirm that the size and type are
correct for your system.
1. Carefully remove the rupture disc from its
packing container.
2. Inspect the rupture disc for damage. Look for
nicks or cuts in the gasket or dents in the dome
of the rupture disc.
3. Unless otherwise specified, the rupture disc
has been cleaned with a water soluble
detergent and is ready for installation. However,
the rupture disc may be cleaned by dipping in
alcohol, using slight agitation and air dried.
B. MAINTAINING EXISTING RUPTURE DISCS
If the rupture disc has not ruptured, it can be
removed, inspected & reinstalled provided the
following conditions are met.

The rupture disc must be free of foreign
material. Corrosion is not evident. The gasket is intact and is not nicked or
scratched. The dome of the rupture disc is not damaged in
any way.
Please note: Visual inspection will not reveal the
effect of process conditions on service life. When in
doubt, install a new disc.
C. FERRULE INSTALLATION WITH 13MHHM
CLAMP
See Figure 1
WARNING: Before attempting to install the rupture
disc, confirm that the rupture disc size matches the
ferrule size.
1. Verify the process flow direction.
2. Silicone, Viton, or EPDM Gaskets place
the rupture disc into the ferrules with the flow
arrow on the rupture disc tag pointing in the
same direction as the desired flow. Go to step 4.
3. Teflon and J-1500 Gaskets carefully place
both of the gasket halves on the rupture disc so
that they interlock around the outside diameter
of the disc and so that the rupture disc tag
extends through the notches in the gasket
halves. Place the assembly into the ferrules
with the flow arrow on the rupture disc tag
pointing in the same direction as the desired
flow. 4. Install the clamp around the ferrules so that the
wing nut is on the same side as the rupture disc
tag.
5. Hand-tighten the wing nut until the clamp is fully
engaged with the ferrules and the rupture disc is
securely in position, approximately 25 in-lbs.
D. FERRULE INSTALLATION WITH FIKE CLAMP
A8647-100-X See Figure 2
WARNING: Before attempting to install the rupture disc,
confirm that the rupture disc size matches the
ferrule size.
1. Verify the process flow direction.
2. Silicone, Viton, or EPDM gaskets place the
rupture disc in the ferrules with the flow arrow on
the rupture disc tag pointing in the same direction
as the desired flow. Go to step 4.
3. Teflon and J-1500 gaskets carefully place both
of the gasket halves on the rupture disc so they
interlock around the outside diameter of the disc so
that the rupture disc tag extends through the
notches in the gasket halves. Place the assembly
into the ferrules with the flow arrow on the rupture
disc tag pointing in the same direction as the
desired flow.
4. Install the A8647-100-X clamp around the ferrules
and orient so the rupture disc tag fits between the
clamp halves at the relief cut out.
5. Tighten the nuts evenly to approximately 150 in-lb
for the 1 1/2 clamp and 240 in-lb for the 2 clamp.
E. NOVASEPTIC (NA CONNECT) INSTALLATION -
See Figure 3
WARNING: Before attempting to install the rupture
disc, confirm that the rupture disc size matches the
ferrule size.
1. Verify the process flow direction.
2. Silicone, Viton, or EPDM Gaskets place the
rupture disc between the female seat and the
outlet ferrule with the flow arrow on the rupture
disc tag pointing in the same direction as the
desired flow.
3. Teflon and J-1500 Gaskets - carefully place both the
gasket halves on the rupture disc so that they
interlock around the outside diameter of the disc
and so that the rupture disc tag extends through the
notches in the gasket havles. Place the rupture disc
between the female seat and the outlet ferrule with
the flow arrow on the rupture disc tag pointing in the
same direction as the desire flow.
4. Install the split flanges on the ferrule and orient so
the rupture disc tag fits between the flanges.
5. Tighten the nuts evenly to approximately 25 in-lbs.
F. ALL INSTALLATIONS
WARNING: Double check the orientation of the
rupture disc. Verify flow arrows on the disc tags are
pointed in the same direction as the desired flow.
Under normal operating conditions, the rupture disc
should be replaced annually. Severe operating
conditions may require that the rupture disc be
replaced more often.
Note: Rupture disc specifications and year of
manufacture can be found on the rupture disc tag.

G. INTEGRATED BURST INDICATOR
WARNING: Read these instructions carefully and
completely before attempting to unpack, install or
service the indicator.

Specific attention must be paid to the circuit.
Special care must be taken to avoid applying any
force to the circuit or Teflon actuator.
INTEGRATED BURST INDICATOR WIRING
The indicator should be wired per the wiring diagram
illustrated in figure 4. Install in accordance with all
applicable local and national codes (in Canada,
Canadian Electric Code, Part 1.).
Note: For hazardous locations, barriers must be
CSA certified and must be installed in accordance
with barrier manufacturers instructions. Barrier
parameters are as follows: 28 V (max.), 300 ohm
(min.).
Note: Rupture disc specifications can be found
on the rupture disc tag. Note: When equipped with
an integrated burst indicator, a tie strap is
recommended to hold the wiring secure to the
piping, as shown in Figure 5.
