Notes
1. Static requirement for losses downstream of the box are
not included. Losses shown are for outlet connection code
FL or SD.
2. In accordance with ARI Standard 885 at minimum inlet
static pressure, for transfer function used in Performance Data
section of catalog.
3. "-" represents NC levels below NC 15. |
