Bryant 558D Automobile User Manual


 
DESCRIPTION
The 558D/559F electric cooling rooftop units are designed to
deliver optimum performance and reliability in a commercial
rooftop unit. The 3 to 25 ton units are one-piece 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 558D/559F units are designed to be field-convertible from
vertical supply/return to horizontal supply/return (180-300 units
require an accessory horizontal supply curb or adapter), making
them easily adaptable to a wide variety of new construction and
replacement applications. For vertical supply/return jobs, duct-
work can be connected directly to the roof curb, allowing duct-
work to be completed before unit is available for installation. All
units include easily replaceable internal filters.
The 558D/559F units are available with a range of accessory,
field-installed electric heating sizes and voltage options to meet
most job requirements. Low-voltage terminal blocks make wir-
ing connections quick and simple.
All units are listed with either UL (Underwriters’ Laboratories)
or ETL (ETLTesting Laboratory) andwith CSA(Canadian Stand-
ards Association), UL Canada, or ETL Canada. All units are ARI
(Air-Conditioning & Refrigeration Institute) approved (except the
size 300, which is beyond the scope of the ARI Certification pro-
gram) and comply with ASHRAE Standard 62 (American Soci-
ety of Heating, Refrigeration, and Air Conditioning Engineers).
STANDARD FEATURES
EFFICIENT DESIGN means cooling energy savings. Standard
units have EERs (energy efficiency ratios) of up to 9.2, and
SEERs (Seasonal Energy Efficiency Ratios) of up to 10.0 (036-
060 units only).
THE FACTORY-ASSEMBLED PACKAGE (036-150 Units) is a
compact, fully self-contained electric cooling unit that is pre-
wired, 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).
NEW TOOL-LESS FILTER ACCESS PANEL (036-150 Units)
provides easy access to filters. The new panel provides addi-
tional access space, permitting easy filter replacement in the
unit, even with an outdoor-air device mounted in a horizontal
position.
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 access filter door. 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 and freeze protection external to the compressor.
These protections prohibit operation under abnormal unit
conditions.
