Bryant 588A Manual page 2

LOW AND HIGH VOLTAGE ELECTRICAL ENTRIES allow low
and high voltage to be brought in either through the duct panel
or rear flue panel.
THE STANDARD CONTROL SYSTEM is readily adaptable to
all conventional and programmable thermostats. In addition,
units are suitable for integration into monitor control systems if
required.
STANDARDIZED COMPONENTS for the complete 588A line of
products are found in all safety devices, condenser-fan motors,
Unit With Base Rail — Unit has rigging and forklift holes and
an elevated mounting frame.
SUGGESTED USE:
• Rigging holes to provide greater ease in handling. Frame to
provide elevation and structural support for horizontal
applications. Ideal for light commercial applications.
Roof Curb — Consists of galvanized steel support frame in
8-, 11-, and 14-in. high designs. Provides wood nailer to attach
roof counter flashing. Insulated basepans in curbs are provided
to prevent condensation. Ductwork attaches to rails provided in
the roof curb. A gasket is provided to form an airtight and wa-
tertight seal between unit and curb. The roof curb design meets
the standards of the NRCA (National Roofing Contractors'
Association).
SUGGESTED USE:
• Slab-mounted applications when elevation of the unit above
the slab is necessary.
• Rooftop application for downflow discharge.
• Curbs are preassembled and are available for flat roofs.
25% Open Manual Outdoor-Air Damper — Package consists
of a manually adjustable damper and includes a rainhood and
birdscreen.
SUGGESTED USE:
• To allow a fixed percentage of outdoor air for ventilation under
all conditions.
• The damper may be used on either downflow or horizontal air-
flow applications.
Thermostat and Subbase — These accessories provide cool-
ing and heating control for unit. Autochangeover and manual
changeover types are available. Thermostats also available as
programmable and non-programmable
SUGGESTED USE:
• To operate and control unit, and to maintain desired building
temperature.
The 0° F Low Ambient Kit — Kit permits operation down to
0° F.
SUGGESTED USE:
• When mechanical cooling is required when outdoor-air tem-
perature is between 40 F and 0° F.
STANDARD FEATURES (cont)
FACTORY-INSTALLED OPTIONS DESCRIPTION AND USAGE
FIELD-INSTALLED ACCESSORIES DESCRIPTION AND USAGE
evaporator-fan motors, and control boards, while the gas sec-
tions use common inducer motors, limit switches, and roll-out
switches. This allows for greater inventory control, familiarity of
parts, and fewer stocked parts.
OPTIONAL BASE RAILS provide holes for rigging and forklift
handling as well as an elevated mounting frame that provides
structural support for horizontal installations. Ideal for light com-
mercial applications.
Downflow Option — Unit is shipped from factory configured for
downflow application. Unit is equipped with base rail.
SUGGESTED USE:
• To provide easy vertical ductwork connections.
Natural-to-Propane Conversion Kit — Kit consists of gas ori-
fices and other hardware required to convert the unit for use
with LP (liquid propane). Installation involves changing the gas
orifices and adding ceramic baffles to accommodate LP.
SUGGESTED USE:
• When natural gas cannot be obtained and liquid propane is
used as fuel.
High Altitude Kit — Kit is available for units installed at 2,001
to 5,000 feet above sea level. Kit consists of natural gas orifices
that compensate for gas heat operation at high altitude.
Filter Rack — Rack features easy installation and service-
ability for vertical applications.
The filter rack housing is constructed of heavy-gage steel for
easy installation.
SUGGESTED USE:
• Kit provides ability to locate filters inside the unit for vertical
applications.
Crankcase Heater — Warms crankcase oil to reduce refriger-
ant migration and ensure proper compressor lubrication.
SUGGESTED USE:
• For use in applications where crankcase is subjected to low
outside temperatures. Recommended on 208/230-v, single-
phase, 024-042 units only.
Solid-State Time Guard II Device — Package consists of a
control to be field-wired into the unit controls, and provides a
5-minute delay in compressor operation between cooling
cycles.
SUGGESTED USE:
• Prevents compressor short cycling when rapid compressor
cycles may be a problem.
