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
and heating capacities. Optional field installed electric heaters
are available in several sizes for additive heating capacity.
CB19 models are applicable to up-flow or down-flow dis-
charge air applications. Units are shipped for up-flow ap-
plications and may easily be field converted to the down-
flow position by turning the unit upside down and
repositioning the coil, drip shields and cabinet access panel.
Filters are not furnished and must be provided by the install-
er. An optional side return air adapter with filter(s) is avail-
able for up-flow applications only. An optional additive
base is available for models with electric heat installed in
the down-flow position on combustible floors.
CBH19 models are designed for horizontal discharge air ap-
plications. Units are furnished with left hand air discharge as
standard and may be field changed to right hand discharge by
turning the unit over (end for end) and repositioning the coil.
CBH19-51 and CBH19-65 models are furnished in a two piece
cabinet with blower and optional electric heaters in one sec-
tion and the indoor coil in the other. Hardware is furnished for
field connection of cabinets. Filters are not furnished and
must be provided by the installer.
