Description

Predator® condensing units and heat pumps are completely

assembled, piped and wired at the factory to provide a single-piece

unit for shipment and rigging. Each unit is pressurized with a holding

charge of refrigerant R-410A for storage and/or shipping.

The compact design, clean styling, small footprint, and quiet operation

make these condensing units and heat pumps suitable for almost any

outdoor location. On rooftops... because they weigh much less than a

single package unit of similar capacity and are much easier to rig and

support. On the ground... because the footprint is compact allowing a

variety of applications.

Both the Predator® condensing units and heat pumps are equipped

with reliable Simplicity® microprocessor controls to assure proper

operation and unit protection for long product life. Products from 10 to

20 tons are available in single or dual (2 or 4 pipe) refrigerant circuits

for redundancy in operation and various application choices such as

one outdoor unit matched with two indoor units.

The Predator® air handling units are completely assembled units,

including a well-insulated cabinet, a DX cooling coil with copper tubing,

aluminum fins, expansion valve(s), distributor(s), 2” throwaway filters,

a centrifugal blower, a blower motor, an adjustable belt drive, a blower

motor contactor and a small holding charge of nitrogen.

Units are shipped in the vertical position ready for field installation, but

can be easily converted to horizontal

position. An added benefit of the

Predator® air handling units is they

are designed to operate with either

a condensing unit or a heat pump

and no field modification or special

unit is required for heat pump

applications.

505428-YTG-M-0512 Condensing Unit Features and Benefits Benefits Features The Predator® 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. • Meets or exceeds ASHRAE 90.1 standards. • Scroll compressors provide both high efficiency and reliability. • Simplicity ® Controls • Dual refrigerant circuits on PD and YD models.

The blower module can be repositioned in the field to meet a large number of vertical and horizontal applications. The 7.5 thru 20 Ton blower module includes the blower wheels along with factory-mounted motor and drive. The 25 Ton blower module includes the blower wheels with field mounted motor and drives. All models offer two motor horsepower options to meet both standard and high static airflow requirements.

505428-YTG-M-0512 Unit Mounting - NC/ND 090 Thru 240 The split air handling units can be applied in various horizontal positions. The Typical Suspension of AHU’s From Ceiling Figure shows recommended suspension rigging using properly sized all-thread and metal c-channel. All components to suspend an AHU must be field supplied. Please refer to the units total weight, center of gravity and corner weights. (Horizontal position) shown in the appropriate table for proper support sizing.

505428-YTG-M-0512 Unit Mounting - NC300 channels and hardware. The channels extend across the evaporator coil section, the heating coil section (if included) and the blower section. Each channel is to be bolted to each section as shown. The NC300 evaporator blower may be suspended from the joists with isolation type hangers or hooks. Suspension accessories 1HH0403 (NC300) may be ordered separately.
