ELECTRIC COOLING UNITS

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.

CONTROLS OPERATING SEQUENCE — SIZE 036-073 UNITS Cooling, Units Without Economizer — When the thermostat calls for cooling, terminals G and Y1 are energized. The indoor (evaporator) fan contactor (IFC), and compressor contactor no. 1 (C1) are energized and the indoor (evaporator) fan motor (IFM), compressor no. 1, and condenser fan start. The outdoor (condenser) fan motor (OFM) runs continuously while unit is cooling.
PAGE 12
CONTROLS (cont) Heating, Units Without Economizer — Upon a call for heating through terminal W1, indoor (evaporator) fan contactor (IFC) and heater contactor no. 1 (HC1) are energized. On units equipped for 2 stages of heat, when additional heat is needed, HC2 is energized through W2. Heating, Units With Economizer — When the room thermostat calls for heat through terminal W1, the indoor (evaporator) fan contactor (IFC) and heater contactor no. 1 (HC1) are energized.
PAGE 13
CONTROLS (cont) As the refrigerant leaves the evaporator, the refrigerant passes a subcooler control low-pressure switch (S-LPS1 for circuit 1 or S-LPS2 for circuit 2) in the suction line. This low-pressure switch will deactivate the Perfect Humidity™ package when the suction pressure reaches 60 psig. The subcooler control lowpressure switch is an added safety device to protect against evaporator coil freeze-up during low ambient operation.
