INSTALLATION INSTRUCTIONS
RDI Rupture Disk Indicator
SERVICE LIMITS
1. The RDI assembly can be used on liquid, gas or two phase flow.
2. Minimum System Operating Pressure:
1” to 2” 5 psig
3” to 2” 3 psig
6” and Up 1 psig
3. Operating Temperature Range: – 40°F (-40°C) to +392°F (200°C).
4. Suitable for intrinsically safe power levels. Maximum current 150mA, maximum voltage 24 Volts AC/DC.
WARNING: Use RDI assembly with intrinsically safe electrical device if used on any hazardous location. Consult
factory on services with fluids that are electrically conductive.
SELECT PROPER LOCATION
1. ALWAYS VENT THE OUTLET TO A SAFE AREA, away from personnel. If the process fluid is toxic or
hazardous connect the outlet side of the rupture disk assembly to a containment tank.
2. Consideration should be given to prevent build-up of rain water, snow, animal nesting or other debris that may
build up in the discharge piping and disturb the normal operation of the BAindicator.
3 If the RDI assembly is to be installed in a horizontal piping system DO NOT orient the RDI cable towards the
bottom. The recommended orientation is towards the top or either side.
INSTALLATION INSTRUCTIONS
1. The RDI assembly is installed on the vent side of the rupture disk assembly normally between the disk holder
and the companion flanges. The assembly is compatible with all ZOOK Graphite and Metal Rupture Disks and
holders. Sizes 1” – 24” are designed to fit within the bolts of standard ANSI class 150 flanges.
2. Clean the clamping surfaces of the companion flanges and if required the disk holder thoroughly.
3. The RDI assembly is NOT ‘Flow Direction’ sensitive. However, it is recommended that the “shiny” side of the
RDI is facing towards the rupture disk. Place the RDI assembly between the companion flange and diskholder
making sure it is centered and concentric with each other.
4. No additional gasket is required on the vent side of the rupture disk assembly. Process side gasket is required.
5. Mark the installation date on the RDI tag.
6. Follow the torquing procedure on next page.
7. Using approved Electrical Code Procedures connect the RDI to the burst detection circuit via the attached
cable.
LEAK DETECTION (LD) OPTION INSTALLATION
1. The LD is installed immediately upstream of the BA indicator.
2. Align outside diameter of LD with outside diameter ofthe BA.
3. The LD may be held in place by using small piece of Scotch® tape over the outside diameter on both sides of
the BA. Locate tape 90° from both sides of identification tag.
Tape must not extend more than half way across gasket surface.
After each leak detection a replacement LD must be installed. Contact ZOOK for replacement LD kits.
