FIELD-INSTALLED ACCESSORIES
Two-Row Hot Water Coils have copper tubes mechanically
bonded to aluminum plate fins and non-ferrous headers.
One-Row Steam Coil has copper tubes and aluminum fins.
The Inner Distributing Tube (IDT) design provides uniform
temperatures across the coil face. The steam coil has a broad
operating pressure range; up to 20 psig (138 kPag) at 260 F
(127 C). The IDT steam coils are especially suited to applica-
tions where sub-freezing air enters the unit.
Electric Resistance Heat Coils have an open-wire design and
are mounted in a rigid frame. Safety cutouts for high tempera-
ture conditions are standard. Terminal block for single-point
power connection is included.
Economizer (Enthalpy Controlled) provides ventilation air
and “free” cooling if outside ambient temperature and humidity
are suitable.
Discharge Plenum directs the air discharge directly into the
occupied space integral horizontal and vertical louvers enable
redirection of airflow. Accessory is available unpainted or
painted. Field assembly required.
Return-Air Grille provides a protective barrier over the return-
air opening and gives a finished appearance to units installed in
the occupied space. Accessory is available unpainted or
painted.
Subbase provides a stable, raised platform and room for con-
densate drain trap connection for vertical floor-mounted units.
Accessory is available unpainted or painted.
Overhead Suspension Package includes necessary brackets
to support units in horizontal ceiling installations.
Bryant’s Line of Thermostats provide both programmable and
non-programmable capability. The Commercial Electronic
thermostats provide 7-day programmable capability for eco-
nomical applications.
Condensate Drain Trap includes an overflow shutoff switch
that can be wired to turn off the unit if the trap becomes
plugged. Kit also includes a wire harness that can be connected
to an alarm if desired. The transparent trap is designed for easy
service and maintenance.
UV-C Germicidal Lamps kill mold and fungus, which may grow
on evaporator coil and condensate pan surfaces. The use of
UV-C germicidal lamps eliminates the foul odors that result from
this growth of mold and fungus. It also provides a self-cleaning
function for the evaporator coil and drain pan.
