INSTALLATION (continued)
1.
Determine the best mounting arrangement for the
RuptureSeal
™ in relation to
the chiller’s existing rupture disk, vent piping, and the recommended supplemental
support. The best arrangement is one that places the
RuptureSeal
™ as close
as possible to the rupture disk. The valve body
(7)
can be rotated to orient the
“outlet to vent pipe”
(8)
in any horizontal direction by loosening the three (3) valve
body locking screws
(9)
(for illustration, see the first row of Appendix “C” on page
16). Once in position, be sure to re-tighten the three (3) valve body locking
screws
(9)
.
2
The
RuptureSeal
™ “valve” should be mounted in the vertical position with the
carbon fragment collection trap chamber
(10)
in the horizontal position (see
Figure 1
-
Typical Installation
). The RS-2 can be mounted in other positions
(
except upside down
), however, the valve is calibrated for the vertical position and
it should be mounted in a position other than vertical only if absolutely necessary.
READ WARNING BELOW
.
Warning:
YOU MUST READ Appendix “C” if mounting in positions other than as
illustrated in Figure 1.
Warning:
Regardless of RS-2’s position, the Double Check Pressure Equalizing Valve
(22)
MUST be mounted vertically with the filter/vent
(34)
pointing up (
é
). Any position
other than with the filter/vent end pointing up will create a serious safety hazard.
3.
Determine how much of the existing rupture disk vent piping will have to be removed to
accommodate the
RuptureSeal
™. Cut out and remove this section of piping.
4.
It is recommended that you utilize a flexible metal connection
(33)
to make the installation easier.
You must use a 2” NPT union
(12)
for future servicing.
5.
The installer shall determine the best way to plumb the exhaust
vent line using the hook-up to vent pipe illustration in Figure 2 as
a guide.
6.
Apply thread sealant compound to threads on the valve’s 2”
carbon fragment collection trap inlet
(13)
and install (see
Caution
below.) This should
be screwed DIRECTLY into the existing
rupture disk flange whenever possible. In no event should the
valve be installed with an extension pipe more than 14 inches
from the rupture disk. (See Appendix “C” on Page 17 for
illustrations if extension must be used
.) IF AN EXTENSION PIPE
IS USED, IT MUST BE STRAIGHT ( NO 45º or 90º ELBOWS)
and have a 2” inside diameter.
[If the valve is not vertical after
tightening into the rupture disk flange, it may be necessary to
install a 2” pipe union between the valve and the outer
rupture disk flange.]
Caution:
Be sure there is a gasket between the carbon rupture disk and the outer
flange. If there is not, one must be installed.
