TEST & BALANCE REPORT SUMMARY This project has been balanced per plans and specifications using the National Environmental Balancing Bureau (NEBB) standards and procedures. The fans have been checked for fan data, operating amperage, voltage, rotation, RPM, belt tension, alignment, and operating static pressure. All outlets have been proportioned to ± 10% of the percentage of total airflow of the system unless otherwise noted. The pump was checked for data, operating amperage, voltage, rotation, RPM, alignment, and operating pressure. The heating water system is supplied with a Griswold Automatic Flow Limiting balance valve. Griswold Automatic Flow Limiting balance valves maintain an optimal flow rate at constant and fluctuating pressure conditions as long the system pressure is set to maintain a minimum range of 2-psi to 32 psi differential pressure at the valve. The Griswold Automatic Flow Limiting valve was verified to be operating within the specified differential pressure range of 2-32 psi.
