3. SERVICE REQUIREMENTS

3.1. Calibrate, Balance and Test

Calibrate the 20 existing terminal boxes for design maximum, minimum and reheat airflows and all associated grilles will be balanced proportionally. If the original drawings do not show all existing grilles, they will be balanced proportionally in each space to provide design total airflow to each room. For grilles in areas that are not shown on the original drawing, airflows will be determined and balanced according to room size/heat load. The air handling unit (AHU) will be tested to determine the proper static pressure set point to control the variable frequency drive (VFD). The fan coil unit (FCU) in the attic will be tested and set to design airflow per the schedule. This unit serves an existing area that is not shown on the drawing. Both units are scheduled to have outside air (OSA) ducted to the system. If this was done, the damper will be set to provide the required minimum fresh air per the schedule at design airflow.

Test existing chilled water and hot water (CW & HW) pumps with all associated valves open to determine total flow. The CW & HW coils at the variable air volume unit (VAV) AHU and the FCU in the attic shall be balanced proportionally to the available total flow. The reheat coils at the terminal boxes shall also be balanced proportionally to ensure proper heating each.

Filters will need to be replaced at the AHU and FCU prior to the test and balance (TAB).
