Johnson Controls Unitary Products

• 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 powered or non-powered 115 volt GFI 

outlet.

• Factory installed phase monitor to protect the unit from 

phase loss or phase reversal.

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.

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).
