(Optional hail guard shown.)

This product has been designed and manufactured to

meet Energy Star® criteria for energy efficiency.

However, proper refrigerant charge and proper air flow

are critical to achieve rated capacity and efficiency.

Installation of this product should follow all

manufacturer’s refrigerant charging and air flow

instructions. Failure to confirm proper charge and

air f low may reduce energy efficiency and shorten

equipment life.

FEATURES AND BENEFITS S Up to 28% lighter than similar industry units. Lighter rooftops make easier replacement jobs. S 3-- 8.5 ton units fit on existing Bryant rooftop curbs making the utility connections the same. This saves time and money on replacement jobs. S Standardized components and layout. Standardized components and controls make service and stocking parts easier. S Scroll compressors on all units. This makes service, stocking parts, replacement, and trouble-- shooting easier.

FACTORY OPTIONS AND/OR ACCESSORIES (cont.) Economizer (dry--bulb or enthalpy) Non--fused Disconnect Economizers save money. They bring in fresh, outside air for ventilation; and provide cool, outside air to cool your building. This is the preferred method of low-- ambient cooling. When coupled to CO2 sensors, Economizers can provide even more savings by coupling the ventilation air to only that amount required.

FACTORY OPTIONS AND/OR ACCESSORIES (cont.) Motormaster Head Pressure Controller Thru--the--Base Connections The Motormaster motor controller is a low ambient, head pressure controller kit that is designed to maintain the unit’s condenser head pressure during periods of low ambient cooling operation. This device should be used as an alternative to economizer free cooling not when economizer usage is either not appropriate or desired.

APPLICATION DATA Min operating ambient temp (cooling): Sizing a rooftop In mechanical cooling mode, your Bryant rooftop can safely operate down to an outdoor ambient temperature of 25_F (-- 4_C). It is possible to provide cooling at lower outdoor ambient temperatures by using less outside air, economizers, and/or accessory low ambient kits. Bigger isn’t necessarily better. While an air conditioner needs to have enough capacity to meet the load, it doesn’t need excess capacity.

SEQUENCE OF OPERATION Cooling, unit without economizer When thermostat calls for cooling, terminals G and Y1 are energized. The indoor-fan contactor (IFC), reversing valve solenoid (RVS) and compressor contactor are energized and indoor-fan motor, compressor, and outdoor fan starts. The outdoor fan motor runs continuously while unit is cooling. 548J Heating, unit without economizer Upon a request for heating from the space thermostat, terminal W1 will be energized with 24V.
PAGE 67
If the space thermostat is satisfied during a defrost cycle, the unit will continue in the Defrost mode until the time or temperature constraints are satisfied. Automatic changeover When the system selection switch is set at AUTO. position, unit automatically changes from heating operation to cooling operation when the temperature of the conditioned space rises to the cooling level setting.
