INSTALLATION
Installation of the
RuptureSeal
™ should be performed only by qualified personnel. The following
installation instructions should be thoroughly read and understood before attempting installation.
Minor alterations to the existing rupture disk vent piping are necessary to install the
RuptureSeal
™
valve. The installer should determine in advance what tools and materials will be needed.
Warning
:
Whenever possible, the RS-2 should be connected directly to the chiller’s
outer rupture disk flange to assure that, if there is a rupture, ALL of the carbon
fragments of the disk will be projected straight into the RuptureSeal™ carbon fragment
collection trap. If this is not possible, see Appendix “C” for further information.
Also, if there is a restriction or constriction in the vent pipe after the
RuptureSeal™ valve, or if a number of chiller reliefs are vented into one inappropriately
sized pipe, the overall flow rate of the system may be negatively affected. Each
installation must have such factors taken into consideration. (For reference, see
ASHRAE Guidelines relating to piping after a rupture device.)
Warning:
DO NOT install an RS-2 RuptureSeal™ on a 3” rupture disk. Likewise,
DO NOT install an RS-3 RuptureSeal™ on a 2” rupture disk. The rated flow capacities
of the RuptureSeal™ relief valve are accurate only when the appropriate Model is used
on an appropriate sized rupture disk. MISMATCHING MAY CAUSE THE VALVE NOT TO
OPEN, HENCE FLOW CAPACITY MAY BE (0) ZERO.
Installation Steps 1 thru 7 - (
see below
)
Warning:
DO NOT attempt to install a damaged valve!
NOTE:
IT IS NOT NECESSARY TO REMOVE THE CHILLER’S RUPTURE DISK TO INSTALL THE
RuptureSeal™
. The valve’s 2” carbon fragment collection trap inlet
(13)
(see Figure 3 on page 9 for
location)
should be screwed directly into the chiller’s outer rupture disk flange (see Figure 1 on Page
8). If this is not possible, see Appendix “C” for other installation possibilities. If the installer wants to
avoid putting stress on the rupture disk assembly, a straight, 2 inch ID flexible coupling can be used
between the rupture disk flange and the
RuptureSeal
™.
