4 Johnson Controls Unitary Products

Features and Benefits

Standard Features

• High Efficiency – High efficiency units reach as high as

11.2 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.

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.

• Coil Technology – ZF condensers utilize Micro-Channel

“all aluminum” condensers which provide improved heat

transfer capabilities and reduced charge volumes.

• Environmentally Aware – For improved Indoor Air

Quality, a combination of foil faced and elastometric

rubber insulation is used exclusively throughout the units.

• Balanced Heating – The Predator

offers “Ultimate

Heating Comfort” with a balance between 1

and 2

stage

gas heating. The first stage of a gas heat Predator

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 low-

pressure 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 temper

ature 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 stan

dard 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 another. 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 lock

outs 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-pres

The Simplicity® control board used in this product

will effectively operate the cooling system down to

0°F when this product is applied in a comfort cooling

application for people. An economizer is typically

included in this type of application. When applying

this product for process cooling applications (com-

puter rooms, switchgear, etc.), please reference

applications bulletin AE-011-07 or call the applica-

tions department for Unitary Products @ 1-877-

UPG-SERV for guidance. Additional accessories

may be needed for stable operation at temperatures

below 30° F.
