524J factory-installed options
Alternate fan motors and drives are available to provide
the widest possible range of performance.
Units constructed of prepainted steel are available from
the factory for applications that require painted units. Unit
color is American Sterling Gray.
524J field-installed accessories
Two-row hot water coils have 5 /
8
-in. diameter copper
tubes mechanically bonded to aluminum plate fins. Coils
have non-ferrous headers.
One-row steam coil has 1-in. OD copper tube and
aluminum fins. The Inner Distributing Tube (IDT) design
provides uniform temperatures across the coil face. The
IDT steam coils are especially suited to applications
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
temperature conditions are standard.
Economizer (enthalpy controlled) provides ventilation
air and provides “free” cooling if the outside ambient
temperature and humidity are suitable. The economizer
can also be used in conjunction with Bryant Comfort
System thermostats and CO
2
sensors to help meet indoor
air quality requirements. The economizer can be used in
both vertical and horizontal positions.
Discharge plenum directs the air discharge into the
occupied space; integral horizontal and vertical louvers
enable redirection of airflow. This accessory is available
unpainted or painted.
Return-air grille provides a protective barrier over the
return-air opening and gives a finished appearance to units
installed in the occupied space. This accessory is available
unpainted or painted.
Subbase provides a stable, raised platform and room for
condensate drain connection for floor-mounted units. This
accessory is available unpainted or painted.
Overhead suspension package includes necessary
brackets to support units in horizontal installations.
CO
2
sensors can be used in conjunction with the
economizer accessory to help meet indoor air quality
requirements. The sensor signals the economizer to open
when the CO
2
level in the space exceeds the setpoint. A
Bryant Comfort System programmable thermostat can
also be used to override the sensor if the outside-air
temperature is too high or too low.
Condensate drain trap includes an overflow shutoff
switch that can be wired to turn off the unit if the trap
becomes plugged. The 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 that may
grow on evaporator coil and condensate pan surfaces. The
use of UV-C germicidal lamps eliminates the foul odors
that result from mold and fungus growth. These lamps
also provide a self-cleaning function for the evaporator
coil and drain pan. Contact application engineer for info.
