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 were checked for data, operating amperage, voltage, rotation, and static pressure. All outlets and inlets were proportioned to +/- 10% of the actual total flow unless otherwise noted.

These units are constant volume. The economizer dampers actuate based on a 2-10 volt DC signal.

RTU-3 is set at 2.0 volts,. RTU-4 is set at 2.80 volts.
