UNIT OPERATING CHARACTERISTICS

Unit shall be capable of starting and running at 125° F outdoor temperature, exceeding maximum load criteria of ARI Standard 340/360. The compressor, with standard controls, shall be capable of operation down to 25° F outdoor temperature. Accessory low ambient kit shall be available for operation to 0° F. Unit shall be provided with fan time delay to prevent cold air delivery before heat exchanger warms up (Gas heat only).

ELECTRICAL REQUIREMENTS

All unit power wiring shall enter unit cabinet at a single factory provided location and be capable of side or bottom entry, to minimize roof penetrations and avoid unit field modifications. Separate side and bottom openings shall be provided for the control wiring.

STANDARD LIMITED WARRANTIES

•Compressor 5 Years

•Heat Exchanger 10 Years

•Electric Heat Element 5 Years

•Other Parts 1 Year

OPTIONAL OUTDOOR AIR (Shall be made available by either/or):

•ELECTRONIC ENTHALPY AUTOMATIC ECONOMIZER - Outdoor and return air dampers that are interlocked and positioned by a fully-modulating,spring-return damper actuator. The maximum leakage rate for the outdoor air intake dampers shall not exceed 2% when dampers are fully closed and operating against a pressure differential of 0.5 IWG. A unit-mounted potentiometer shall be provided to adjust the outdoor and return air damper assembly to take in CFM of outdoor air to meet the minimum ventilation requirement of the conditioned space during normal operation. During economizer operation, a mixed-air temperature control shall modulate the outdoor and return air damper assembly to prevent the supply air temperature from dropping below 55°F. Changeover from compressor to economizer operation shall be provided by an integral electronic enthalpy control that feeds input into the basic module. The outdoor intake opening shall be covered with a rain hood that matches the exterior of the unit. Water eliminator/filters shall be provided. Simultaneous economizer/compressor operation is also possible. Dampers shall fully close on power loss.

•BAS-READY ECONOMIZER - Outdoor and return air dampers that are interlocked and positioned by a fully- modulating, spring return damper actuator. The maximum leakage rate for the outdoor air intake dampers shall not exceed 2% when dampers are fully closed and operating against a pressure differential of 0.5 IWG.

For units with optional VAV or Simplicity® Intelli-Comfort™ control, free-cooling shall be available while the outdoor dry bulb temperature (OAT) remains below a programma- ble set-point of the controller. Field-installed humidity sen- sors for either outdoor air or outdoor & return air streams are available to provide free-cooling based on single-

enthalpy or dual-enthalpy configurations, respectively. If free-cooling is available, a call for cooling shall modulate the economizer in order to maintain a supply air tempera- ture (SAT) programmable set-point. With the use of a field-installed indoor air quality sensor, the controller shall provide Demand Ventilation by modulating the econo- mizer dampers to allow more outside airflow upon detec- tion of elevated indoor CO2 concentrations above a programmable set-point. With an additional field-installed outdoor air quality sensor, Differential Demand Ventilation shall be provided.

The outdoor intake opening shall be covered with a rain hood that matches the exterior of the unit. Water elimina- tor/filters shall be provided.

Simultaneous economizer/compressor operation is also possible. Dampers shall fully close on power loss.

•MOTORIZED OUTDOOR AIR DAMPERS - Outdoor and return air dampers that are interlocked and positioned by a 2-position,spring-return damper actuator. The maximum leakage rate for the outdoor air intake dampers shall not exceed 2% when dampers are fully closed and operating against a pressure differential of 0.5 IWG. A unit-mounted potentiometer shall be provided to adjust the outdoor and return air damper assembly to take in the design CFM of outdoor air to meet the ventilation requirements of the conditioned space during normal operation. Whenever the indoor fan motor is energized, the dampers open up to one of two pre-selected positions - regardless of the outdoor air enthalpy. Dampers return to the fully closed position when the indoor fan motor is de- energized. Dampers shall fully close on power loss.

OTHER PRE-ENGINEERED ACCESSORIES AVAILABLE

•ROOF CURB - 14" high, full perimeter curb with wood nailer (shipped knocked-down).

•100% BAROMETRIC RELIEF DAMPER - Contains a rain hood, air inlet screen, exhaust damper and mounting hardware. Used to relieve internal air pressure through the unit.

•PROPANE CONVERSION KIT - Contains new orifices and gas valve parts to convert from natural to L.P. gas. One per unit required.

•HIGH ALTITUDE - NATURAL GAS - Contains orifices required for applications between 2000 and 6000 feet altitude.

•HIGH ALTITUDE - PROPANE GAS - Contains orifices required for applications between 2000 and 6000 feet altitude. Must be used with propane conversion kit.

•BURGLAR BARS - Designed to work with above roof curbs, depending on unit model. Fits duct openings of curb supply and return air openings.

•SIDE DUCT FLANGE - Supply and return air duct flanges for side duct applications. Do not use on units with power exhaust.

•HIGH STATIC DRIVE - May Include a belt, blower pulley, motor pulley or a motor change to enhance blower performance.
