temperature. 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 ECONO- MIZER - Outdoor and return air dampers that are inter- locked 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 potenti- ometer 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 condi- tioned space during normal operation. During econo- mizer 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 oper- ation shall be provided by an integral electronic enthalpy control that feeds input into the basic module. The out- door intake opening shall be covered with a rain hood that matches the exterior of the unit. Water eliminator/fil- ters shall be provided. Simultaneous economizer/com- pressor 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 maxi- mum 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 posi- tions - 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 mount- ing hardware. Used to relieve internal air pressure through the unit.
