Page 9: Installation
1. Blowdown Before installing the CV-COSR unit, be sure to blow down all piping thoroughly. If this is not possible, perform a blowdown using the bypass valve. Blowdown is especially important for newly installed piping or after the system has been shut down for a long period of time. - Page 10 9. Shut-off Valve Installation Though the CV-COSR adequately performs the function of a shut-off valve initially, extended use will result in a drop in its performance as an isolation valve. Be sure to install a separate shut-off or automatic valve if complete isolation is needed.
