Applications — The CB19 and CBH19 blower coil units are de-
signed for multi-position installation in a basement, utility
room, alcove, closet, crawlspace or attic. Units are applicable
to expansion valve systems in cooling applications and
check and expansion valve systems in heat pump applica-
tions. Units have factory installed check and expansion valve.
Several models are available in varying sizes with a wide
range of cooling and heating capacities. See Condensing Unit
bulletins in section Cooling Units — Condensing Units for
cooling capacities. See Heat Pump Outdoor Unit Bulletins in
section Heat Pumps — Matched Remote Systems for cooling
