1 Cautions and Warnings
1. It is recommended that the installer and operator utilize the appropriate personal safety equipment while
interacting with the Corrosion Coupon Rack (CCR); i.e. safety glasses, gloves, etc.
2. It is the installer’s responsibility to install the product away from sensitive equipment such as open electrical
devices to protect from potential electrical shock and or damage in the event of a leak or failure of the CCR
assembly.
3. It is the installer’s responsibility to provide for secondary containment, leak detecting equipment and or
drainage of potential water that may drip from the CCR during normal usage or in the unlikely event of a
rupture/failure.
4. This device has a rated operating pressure; however rapid pressure spikes that result from water hammer or
uncontrolled surges from external sources can cause pressures far above the rating of the product. The
purchaser/installer must make sure these spikes are prevented to assure safe operation of the CCR.
5. PVC versions of the CCR can be affected by high temperatures. The device is not designed to operate above
140O F (60O C). Pressure is also derated at higher temperatures.
6. Any modification to the CCR voids the warranty and any resulting failure is the sole responsibility of the
purchaser/installer.
7. Removal of the CCR piping from the supplied back plate is a modification not allowed and voids the warranty.
8. Prior to any service to the unit, always close the inlet isolation valve and release the pressure and completely
drain the unit.
