FEATURES

• High Efficiency – High efficiency units reach as high as

11.5 EER. Gas/electric units have electronic spark ignition and power vented combustion with steady state efficiencies of 80%. These efficiencies exceed all legislated minimum levels and provide low operating costs.

• Service Friendly – The Predator® incorporates a number of enhancements which improve serviceability.

The motor and blower slide out of the unit as a common assembly. This facilitates greater access to all the indoor airflow components, thus simplifying maintenance and adjustment.

Service time is reduced through the use of hinged, toolless panels. Such panels provide access to frequently inspected components and areas, including the control box, compressors, filters, indoor motor & blower, and the heating section. The panels are screwed in place at the factory to prevent access by children or other unauthorized persons. It is recommended that the panels be secured with screws once service is complete.

Unitary Products Group 3

Service windows have been placed in both condenser section walls. Rotation of the cover allows easy access to the condenser coils for cleaning or inspection.

Both the unit control board and ignition control board utilize flash codes to aid in diagnosis of unit malfunctions. Unique alarm codes quickly identify the source of the unit alarm.

All units use the same standard filter size. This standardization removes any confusion on which filter sizes are needed for replacement.

The non-corrosive drain pan slides out of the unit to permit easy cleaning. The drain pan is accessed by removing the drain pan cover plate on the rear of the unit. Once the plate is removed, the drain pan slides out through the rear of the unit.

All Predator

units have a second model nameplate located inside the control access door. This is to prevent deterioration of the nameplate through weathering.

• Environmentally Aware – For improved Indoor Air Quality, foil faced insulation is used exclusively throughout the units.

• Balanced Heating – The Predator ing Comfort” with a balance between 1st and 2nd stage gas heating. The first stage of a gas heat Predator

offers “Ultimate Heat-

unit provides 60% of the heating capacity. Balanced heating allows the unit to better maintain desired temperatures.

• Convertible Airflow Design – The side duct openings are covered when they leave the factory. If a side supply/ return is desired, the installer simply removes the two side duct covers from the outside of the unit and installs them over the down shot openings. No panel cutting is required. Convertible airflow design allows maximum field flexibility and minimum inventory.

• System Protection - Suction line freezestats are supplied on all units to protect against loss of charge and coil frosting when the economizer operates at low outdoor air temperatures while the compressors are running. Every unit has solid-core liquid line filter-driers and high and lowpressure switches. Internal compressor protection is standard on all compressors. Crankcase heaters are standard on reciprocating compressors. Scroll compressors do not require crankcase heaters. Phase Monitors are standard on units with scroll compressors. This accessory monitors the incoming power to the unit and protects the unit from phase loss and reversed phase rotation.

• Advanced Controls - Simplicity™ control boards have standardized a number of features previously available only as options or by utilizing additional controls.

• Low Ambient - An integrated low-ambient control

allows all units to operate in the cooling mode down to 0°F outdoor ambient without additional assistance. Optionally, the control board can be programmed to lockout the compressors when the outdoor air temperature is low or when free cooling is available.

• Anti-Short Cycle Protection - To aid compressor

life, an anti-short cycle delay is incorporated into the standard controls. Compressor reliability is further ensured by programmable minimum run times. For testing, the anti-short cycle delay can be temporarily overridden with the push of a button.

• Fan Delays - Fan on and fan off delays are fully pro-

grammable. Furthermore, the heating and cooling fan delay times are independent of one ano ther. All units are programmed with default values based upon their configuration of cooling and heat.

• Safety Monitoring - The control board monitors the

high and low-pressure switches, the freezestats, the gas valve, if applicable, and the temperature limit switch on gas and electric heat units. The unit control board will alarm on ignition failures, compressor lockouts and repeated limit switch trips.

• Nuisance Trip Protection and Strikes - To prevent

nuisance trouble calls, the control board uses a “three times, you’re out” philosophy. The high and

low-pressure switches and the freezestats must trip three times within two hours before the unit control board will lock out the associated compressor.

• On Board Diagnostics - Each alarm will energize a trouble light on the thermostat, if so equipped, and flash an alarm code on the control board LED. Each high and low-pressure switch alarm as well as each freezestat alarm has its own flash code. The control board saves the five most recent alarms in memory, and these alarms can be reviewed at any time. Alarms and programmed values are retained through the loss of power.

• Reliable – From the beginning – All units undergo computer automated testing before they leave the factory. Units are tested for refrigerant charge and pressure, unit amperage, and 100% functionality. For the long term – All Predator

units are painted with a long lasting, powder paint that stands up over the life of the unit. The paint used has been proven by a 1000 hour salt spray test.

• Flexible Placement – All models and configurations share the same cabinet/footprint and thus the same roof curb. You have the flexibility to set one curb and choose the correct tonnage size and heating option after the internal loads have been determined.

To further simplify planning and installation, Predator cabinets are designed to fit your roof. With the optional roof curb, the unit ductwork is designed to fit around 24” on-center joists or between 48” on-center joists.

The drain pan can be rotated to drain to either the front or the rear of the unit. Additionally, the drain pan can be fitted to drain through the roof curb. As it is sometimes difficult to have a level installation, the drain pan features a generous slope to ensure proper drainage.

• Full Perimeter Base Rails – The permanently attached base rails provide a solid foundation for the entire unit and protect the unit during shipment. The rails offer forklift access from 3 sides, and rigging holes are available so that an overhead crane can be used to place the units on a roof.

• Easy Installation – Gas and electric utility knockouts are supplied in the unit underside as well as the side of the unit. A clearly identified location is provided to mount a field supplied electrical disconnect switch. Utility connections can be made quickly and with a minimum amount of field labor.

All units are shipped with 2” throw-away filters installed.

• Wide Range of Indoor Airflows – All indoor fan motors are belt-drive type providing maximum flexibility to handle most airflow requirements. For high static applications, factory installed alternate indoor fan motors are available. With the optional indoor fan motor, all units can supply nominal airflow at a minimum of 1.5” ESP.

• Warranty - All models inclu de a 1-year limited warranty on the complete unit. Compressors and e lectric heater elements each carry a 5-year warranty. Aluminized steel and stainless steel tubular heat exchangers carry a 10year warranty.

• CO

Sensor - Senses CO2 levels and automatically

overrides the economizer when levels rise above the preset limits.

• Coil Guard - Field installed decorative wire coil guard.

• Hail Guard - This kit includes a sloped hood which installs over the outside condenser coil and prevents damage to the coil fins from hail strikes. Field installed accessory only.

• Flue Exhaust Extension Kit - In locations with wind or weather conditions which may interfere with proper exhausting of furnace combustion products, this kit can be installed to prevent the flue exhaust from entering nearby fresh air intakes.

• -60°F Gas Heat Kit - For installations which require gas heat units to perform in low ambient temperatures, a gas section heating kit is available. This kit provides electric heat in the gas heat controls section to ensure the gas valve and controls will continue to function properly at extremely low temperatures.

• Gas Heat High Altitude Kit - This kit converts a gas heat unit to operate at high altitudes, 2,000 to 6,000 feet. Conversion kits are available for natural gas and propane.

• Gas Heat Propane Conversion Kit - This kit converts a gas-fired heater from natural gas to propane. It contains the main burner orifices and gas valve replacement springs.

• Gas Piping Kit - Contains pipe nipples, fittings and gas cock required for gas supply connection with external shut off.

• Electric Heaters - The electric heaters range from 9 kW to 54kW and are available in all the voltage options of the base units. All heaters are dual staged. Cooling units include an adapter panel for easy installation of the electric heaters. Necessary hardware and connectors are included with the heaters. All heaters are intended for single point power supply.

• Low Limit / Compressor Lockout Kit

1. Compressor Lockout (CLO): To prevent mechani-

cal (compressorized) operation of the unit during cold outdoor conditions where there is a risk of returning liquid refrigerant back to the compressors.

2. Low Limit Control (LLC): To prevent the supply air

from dropping below a specified setpoint by utilizing the units first stage heating means when there is a demand for cooling during cold outside conditions.

• Metal Frame Filter Kit - Metal frame with polyester filter medium.

• Permanent Filters - Permanent filters are available.

• Roof Curbs - The roof curbs have insulated decks and are shipped disassembled The roof curbs are available in 8” and 14” heights. For applications with security concerns, burglar bars are available for the duct openings of the roof curbs.

• Roof Curb Transition - Single Piece Adapter (10” High)

- Roof curbs for transitioning from Sunline™ units to Predator

units. Fits 7.5 to 12.5 Sunline™ roof curbs

only.

• Burglar Bars - Mount in the supply and return openings to prevent entry into the duct work.

• Thermostat - The units are designed to operate with 24- volt electronic and electro-mechanical thermostats. All units (with or without an economizer) operate with twostage heat/two-stage cool or two-stage cooling only thermostats, depending upon unit configuration.
