Installation Kit Kit includes: One (1) Pre-assembled RS-2 RuptureSeal™ which includes: 3 O-rings & NOTE: Eight (8) 1/4” Stainless Steel Cap Screws See Figure One (1) Collection Trap Chamber Cover 3 on Page 9 One (1) Carbon Fragment Collection Trap Canister Insert for location of parts on with Special Tack Compound...
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.
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 can be rotated to orient the “outlet to vent pipe”...
Tee The ALARM should be set to activate between 4 and 10 psig. Contact equipment servicing for information on the optional Redi Controls Alarm™. Supplemental Mounting Support It is recommended that a supplemental mounting support be provided for the RuptureSeal™ valve to relieve any stress it may put on the rupture disk assembly (see Figure 1 on page 8).
Otherwise, accidental bursting of the rupture disk could occur by imploding the rupture disk into the chiller! (35) 1. Remove pipe plug (or alarm, if the optional Redi Controls Alarm™ is used) from alarm port (14) of Tee 2. Utilizing a 1/8” NPT x 1/4” Flair half union, connect a refrigeration manifold set (low side hose) to...
MAINTENANCE Following a Rupture Perform “Annual” maintenance procedures (steps 1 thru 16 - see below) and replace the Carbon Fragment Collection Trap Canister Insert with a fresh one. Annual Warning: Removal of the wired screws and lead seal from the valve body will destroy the pressure relief calibration and void the warranty.
MAINTENANCE (continued) (10) 11. Remove the collection trap canister from the trap chamber and inspect the tack compound. The compound should be soft and very tacky to the touch. If not, or if there is any doubt about the quality of the tack compound, replace with a new canister with fresh compound. (Contact equipment servicing for Kit “RS-2 TACK KIT”...
Appendix “A” ™ RuptureSeal Model RS-2 (940 SCFM) R-11 R-113 R-123 Purpose of Table This table will assist the installer in determining the maximum size of chiller vessel (evaporator) with a two inch (2”) carbon rupture disk that can be fitted with the Model RS-2 RuptureSeal™ valve. (NOTE: PURSUANT TO ASHRAE GUIDELINES, WHEN A PRESSURE RELIEF DEVICE IS INSTALLED IN SERIES WITH A RUPTURE DISK, THE FLOW CAPACITY OF THAT DEVICE MUST BE DE-RATED BY 10%.) Thus, after installation in series with a two inch (2”) carbon rupture disk, the...
Appendix “B” Excerpt from Guideline BSR/ASHRAE 15-1992R 9.7.5 The minimum required discharge capacity of the pressure-relief device or fusible plug for each pressure vessel shall be determined by the following: C = f DL WHERE: minimum required discharge capacity of the relief device in POUNDS OF AIR PER MINUTE (KG/S), (emphasis and asterisk added) outside diameter of vessel...
Appendix “C” ONLY IF ABSOLUTELY NECESSARY, the RS-2 can be mounted in positions other than the preferred “Typical Installation” position illustrated in Figure 1 on page 8 (but not upside down). See the following illustrations for other possible mounting positions. NOTE: If the RS-2 RuptureSeal™...

Appendix “C” (continued) Variations in RS-2 valve mountings to a chiller’s rupture disk. The RuptureSeal™ is designed to be installed directly into the outer flange of the chiller’s rupture disk, WITHOUT THE USE OF A 45º or 90º ELBOW TURN BETWEEN THE RUPTURE DISK AND THE RuptureSeal™, or any piping extensions.
