INDOOR UNIT OVERVIEW
Table 2: Ducted Indoor Units.
1
All indoor units require 208–230V/60Hz/1Ph and an AWG18-2 communication cable.
2
Model number shows nominal capacity and frame size designator.
3
Nominal cooling capacity rating obtained with air entering the indoor unit at 80ºF dry bulb (DB) and
67ºF wet bulb (WB) and outdoor ambient conditions of 95ºF dry bulb (DB) and 75ºF wet bulb (WB).
Nominal heating capacity rating obtained with air entering the indoor unit at 70ºF dry bulb (DB) and 60°
F wet bulb (WB) and outdoor ambient conditions of 47ºF dry bulb (DB) and 43ºF wet bulb (WB).
