1. capacity based on 70ºF return air, high speed and 12.5 feet length per branch at 4”
diameter. Two 3” branches = one 4”, two 4” = one 6”. Do not exceed grille rating. Higher
static pressure/reduced heating capacity available at lower airflow.
2. Regular ZC requires external cooling coil (extra) in the return air duct.
3. Tall ZCT can use cooling A-coil supplied by others. Cabinet opening is 20W x 24D x 21H.
