Product data shall be submitted, in accordance with Section 23 00 00, for each of the following :  \n1. Procedure Submittal: Prior to commencing work, submit, for approval, a written procedure of how balance will be performed and a description and manufacturer’s name of equipment and instruments to be used. The submittal shall include, but not necessarily be limited to the following:  \na. List of preliminary checks to be performed at the job site such as confirmation that manual volume dampers are present, filters are installed, frequency drive units operational, location of control sensors, etc.  \nb. Identify how the air outlets will be measured and the type of instruments to be used.  \nc. Locations of pilot traverses and the type of instruments to be used.  \nd. Modes of operation that the system will be placed in during balancing and testing, i.e., full cooling and heating, maximum and minimum outside air flows, maximum and minimum sash positions for fume hoods, toilet fans on or off, etc.  \ne. Position of doors and windows during balance, i.e., some labs should be balanced with doors shut.  \nf. Operating static pressures for terminal devices and pressure sensors for controlled devices.  \ng. Method of adjusting outside and return air quantities at air handling units.  \nh. Initial test procedures for preliminary balance.  \ni. Final test procedures.  \nj.
