Bryant 579F - Manual

DESCRIPTION
The 579/580 gas heating/electric cooling rooftop units are de-
signed to deliver optimum performance and reliability in a com-
mercial rooftop unit.
The 3 to 25 ton units are one-piece gas heating, electric cooling
units that are prewired and precharged with R-22 at the factory,
making jobsite installation easy. Every unit is factory run-tested
prior to shipment to ensure reliable installation.
The 579/580 units are designed to be field-convertible from ver-
tical supply/return to horizontal supply/return (180-300 units
require an accessory horizontal roof curb or horizontal adapter),
making them easily adaptable to a wide variety of new construc-
tion and replacement applications. For vertical supply/return
jobs, ductwork can be connected directly to the roof curb, allow-
ing ductwork to be completed before unit is available for instal-
lation. All units include easily replaceable internal filters.
The 579/580 units are available in a range of heating sizes and
voltage options to meet most job requirements. Low-voltage ter-
minal blocks make wiring connections quick and simple.
All units are listed with either UL (Underwriters’ Laboratories) or
ETL Laboratories and with CSA (Canadian Standards Associa-
tion), UL Canada, or Warnock Hersey. All units are ARI (Air-
Conditioning & Refrigeration Institute) approved (except the 300
unit, which is beyond the scope of the ARI certification program)
and comply with ASHRAE Standard 62 (American Society of
Heating, Refrigeration, and Air Conditioning Engineers).
STANDARD FEATURES
EFFICIENT DESIGN means cooling and heating energy sav-
ings. Standard units have EERs (energy efficiency ratios) of up
to 9.2 and SEERs (seasonal energy efficiency ratios) of 10.0
(036-060 belt drive units only). The 580D units have an AFUE
(Annual Fuel Utilization Efficiency) rating of 80.0% with a Cali-
fornia Seasonal Efficiency rate of 75.8% or better. All 579/580
units have a steady-state efficiency of 80.0%.
THE FACTORY-ASSEMBLED PACKAGE is a compact, fully
self-contained electric cooling/gas heating unit that is prewired,
prepiped, and precharged for minimum installation expense.
UNITS MAY BE CONVERTED TO HORIZONTAL DIS-
CHARGE in the field. The units can be modified at the jobsite to
fit a variety of applications (180-300 units require an accessory
horizontal supply/return roof curb or a horizontal supply/return
adapter).
INTERNAL RETURN-AIR FILTERS are provided. Two-in.
throwaway filters are provided standard on all units, and can be
easily accessed through the tool-less filter access panels. There
is no need to field-fabricate filter racks or install external filter
accessories.
COMPRESSOR PROTECTION is assured. The 036-150 units
have an internal pressure relief valve and line break (current
overload) protections, and the 180-300 units have high- and
low-pressure protection external to the compressor. These pro-
tections prohibit operation under abnormal unit conditions.
