FEATURES/BENEFITS

•Efficient cooling using hermetic compressors.

•Full range of electric heat sizes available — exactly the right size for your needs.

•Accessory hydronic glycol heating coils are available for unit sizes 155-300.

•High reliability — non-corrosive condensate pans (036-150), prepainted cabinets and primed interior panels, and all units are fully protected by internal safeties.

•Quietest operation in the industry — all compressors mounted on independent vibration isolators. Standard belt-driven evaporator fan motors on all units (except 558F036-060).

•Ease of maintenance achieved by standard size filters, tool- less filter access, simple compressor access, permanently lubricated fan motors, optional disconnect switch, optional 115-v convenience outlet, and optional hinged access panels.

•Perfect Humidity™ dehumidification package (not available on 558F036-150 units). This factory-installed option im- proves the dehumidification capability of the rooftop unit and helps control humidity levels in the conditioned space.

BRYANT MEANS TOP QUALITY AND RELIABILITY — Each component utilized in these units is designed and tested for a minimum of 15 years operation under the harshest conditions.

Every unit is thoroughly run tested at the factory in each oper- ating mode and evacuated prior to final charging. Every coil is leak-tested with helium particles. Automated run testing allows accurate impartial tests and measurements which are second to none in the industry.

Each unit contains a factory printout indicating tested pressures, amperages, dates, and inspectors, providing certifi- cation of the unit’s status at the time of manufacture.

Units are equipped with valuable safety controls designed to monitor and protect the unit for life. The standard safeties include:

•low-pressure/loss-of-charge switch

•high-pressure switch

•freeze-protection thermostat

•internal compressor overload

•exclusive Cycle-LOC™ circuit board that provides compres- sor anti-cycling (except 558F036-150)

•refrigerant filter drier

The cabinet is constructed of galvanized steel, bonderized and coated with a prepainted baked enamel finish. The paint finish is a non-chalking type, and is capable of exceeding Federal Test Method Standard No. 141 (Method 6061) 500-Hour Salt Spray Test. In addition, all internal cabinet panel surfaces are primed, allowing the entire unit to have a longer life and more attractive appearance.

EASY MAINTENANCE AND INSTALLATION

All Units are Factory Shipped in the Vertical Discharge Configuration for fit-up to standard roof curbs. (One acces- sory curb fits sizes 036-072; accessory curbs fit sizes 090-150 and 155-300.) The contractor can order and install the roof curbs early in the construction stage, before decisions on size requirements have been made.

All Units Feature Roll-Formed Baserail design with forklift slots on 3 sides of the unit and rigging holes for easier maneu- vering and installation. Stretch-wrap packaging protects the unit during shipment and storage.
