Features

•Meets or exceeds ASHRAE 90.1 standards.

•Scroll compressors provide both high efficiency and reliability.

•Simplicity® Controls

•Dual refrigerant circuits on PJ and YJ models.

•Condensing unit coils are constructed of reliable and durable Micro-Channel aluminum tube and fins for long lasting, efficient operation. Mirco-Channel technology provides exceptional durability along with reduced product weight and less refrigerant charge. Heat pumps units are equipped with aluminum fin, copper tube coils providing durability, reliability and value.

•Multiple condensing unit and air handler match-ups provide a wide range of application choices from oversized indoor motors to dual indoor units matched- up with single outdoor units.

•Crankcase heaters that will be de-energized when compressors are operating.

•Both high and low pressure controls. Since these controls are self-contained, there are no capillary lines to be damaged.

•Internal compressor motor protection.

•Class 2, 24-volt thermostat control circuit protected by a re-settable breaker.

•Standard factory installed service valves.

•Filter-driers are shipped in the unit's control box for field installation in the liquid line leaving the outdoor unit.

•Copper stub-outs are factory mounted on the suction and liquid lines to simplify the field piping connections.

•Simplicity® Controls provide stable cooling operation at ambient temperatures down to 40°F with low ambient kits available for operation to 0°F.

•Capacity staging for more economical operation and stable temperature levels within the conditioned space.

•Simplicity® Controls prevent the unit from cycling on safety control with “Three Outs” technology preventing nuisance trips, but protecting the equipment when valid operational issues are experienced.

•Simplicity® Controls monitor each safety independently (High pressure, low pressure, low voltage) allowing ease of troubleshooting if any problems arise.

•Inherently protected condenser fan motors.

•Technicoated outdoor coils for sea coast or corrosive environment applications.

•Factory installed disconnect to allow power to be removed from the unit when performing periodic maintenance or for service.

•Factory installed phase monitor to protect the unit from phase loss or phase reversal.

Benefits

The UP condensing units and heat pumps can be applied on a rooftop or at ground level... due to their ample sub-cooling capacity which allows them to be located three or more stories below the evaporator coil.

After assembly, the unit is pressurized with a combination of Refrigerant R-410A and nitrogen for pressure testing and additional leak testing. During this pressure test, the operation of the high pressure control is checked. As the unit is being evacuated and dehydrated, the operation of the low pressure control is also checked.

Every compressor, condenser fan motor, crankcase heater, and electrical control circuit is checked to assure a trouble- free start-up and years of reliable operation. The condenser fan guards are vinyl-coated to provide additional rust protection and to enhance the appearance of the unit. Compressors are mounted on rubber isolators to reduce the transmission of vibration. Vertical discharge condenser fans direct sound upward and away from any surrounding structures.

All sheet metal parts are constructed of commercial grade galvanized steel. After fabrication, each part is thoroughly cleaned to remove any grease or dirt from its surfaces. The external parts are coated with a powder paint to assure a quality finish for many years. This UL approved coating system has passed the 1000 hour, 20% salt spray test per ASTM Standard B117.

All condensing unit and heat pump models include a 5-year limited warranty on the compressor(s) and 1-year limited warranty on all other parts. The matching line of air handling units carries a 1-year limited parts warranty.

Outdoor Unit Accessories

Coil Guards: Wireform coil guards for added protection of outdoor coils. Designed to mount on each side of the product if required to provide protection from minor impacts or large debris.

Hail Guards: Hood type hail guards designed to protect the outdoor coils from hail. Can be installed on a single side or both to provide protection from storms that may produce hail.

Low Ambient Kits: Kits designed to allow the cooling only units to operate between 0°F and 40°F in the cooling mode. Standard cooling is allowed to 40°F. (Not designed for operation on heat pump units).

R-410A specifications

Johnson Controls R-410A is a widely recognized refrigerant in the HVAC industry, primarily used in air conditioning and heat pump applications. Known for its environmental benefits and efficiency, R-410A has risen to prominence as a reliable replacement for older refrigerants such as R-22, which are being phased out due to their harmful impact on the ozone layer.

One of the standout features of R-410A is its low impact on global warming potential, making it an environmentally-friendly choice. It is composed of a mixture of hydrofluorocarbons (HFCs), specifically difluoromethane (R-32) and pentafluoroethane (R-125). This blend allows for efficient heat transfer while minimizing harmful emissions, addressing the growing concerns over climate change.

Johnson Controls emphasizes the efficiency of R-410A systems, which can provide a highly effective cooling performance. They are designed to operate at higher pressures compared to R-22, allowing for more efficient heat exchange and better overall system performance. This results in greater energy efficiency ratings, contributing to lower electricity bills for consumers.

In terms of technology, R-410A systems often feature advanced compressor designs and enhanced coil configurations, which optimize the system’s performance. Johnson Controls integrates state-of-the-art variable speed technologies and smart controls that enhance responsiveness and adaptability to changing environmental conditions. These innovations not only improve thermal comfort but also reduce energy consumption, leading to a smaller carbon footprint.

Another significant characteristic of R-410A is its compatibility with various lubricants, which is crucial for maintaining system performance and longevity. Johnson Controls often utilizes specially formulated lubricants that work optimally with R-410A, ensuring reliable operation and reducing the risk of issues related to lubrication.

In summary, Johnson Controls R-410A is an important refrigerant characterized by its efficient, environmentally friendly properties and advanced technologies. Its application in modern HVAC systems provides users with excellent performance, substantial energy savings, and an effective solution for climate-conscious cooling. As the industry continues to evolve, R-410A remains a central player in the push toward more sustainable and efficient heating and cooling solutions.
