FIELD-INSTALLED ACCESSORIES

SINGLE INPUT ELECTRONIC ENTHALPY ECONOMIZERS

Includes a slide-in/plug-in damper assembly with fully modulating spring-return monitor actuator capable of introducing up to 100% outdoor air with nominal 1% leakage type dampers.

The enthalpy system contains one sensor that monitors the outdoor air and determines when the air is cool enough and dry enough to provide “free” cooling.

The rainhood is painted to match the basic unit and must be field-assembled before installing.

Power exhaust is not available as a field installed option.

DUAL INPUT ELECTRONIC ENTHALPY

ECONOMIZERS

Includes a slide-in / plug-in damper assembly with fully modulating spring-return monitor actuator capable of introducing up to 100% outdoor air with nominal 1% leakage type dampers.

This enthalpy system contains one sensor that moni- tors the outdoor air and one sensor that monitors the return air. The logic module compares these two val- ues and modulates the dampers providing the maxi- mum efficiency of economizer system.

The rainhood is painted to match the basic unit and must be field-assembled before installing.

Power exhaust is not available as a field installed option.

MOTORIZED OUTDOOR AIR INTAKE DAMPER

Includes a slide-in/plug-in damper assembly with a

2-position, spring return motor actuator which opens to some pre-set position whenever the supply air blower is operating and will drive fully closed when the blower unit shuts down.

The rain hood is painted to match the basic unit and must be field assembled before installing.

Power exhaust is not available as a field installed option.

ROOF CURBS

Fourteen inch high roof curbs provide a water-tight seal between the unit and the finished roof. These full perimeter curbs meet the requirements of the National Roofing Contractors Association (NRCA) and are shipped knocked-down for field assembly. They're designed to fit inside the base rails of the unit and include both a wood nailing strip and duct hanger sup- ports.

ANTI-RECYCLE TIMERS

Two solid state timers prevent the compressors from short-cycling. Once a compressor is de-energized, it will remain de-energized for approximately five min- utes.

HIGH ALTITUDE NATURAL GAS

Burner orifices and pilot orifices are provided for proper furnace operation at altitudes up to 6,000 feet.

PROPANE

Burner orifices, pilot orifices and gas valve parts are provided to convert a natural gas furnace to propane.

HIGH ALTITUDE PROPANE

Burner orifices and pilot orifices are provided for proper furnace operation at altitudes up to 6,000 feet. This accessory supplements the basic propane conversion kit.

SIDE DUCT FLANGES

One inch flanges replace the supply and return air pan- els on the rear of the unit to accommodate horizontal duct connections. These flanges can also be used indi- vidually for bottom supply/horizontal return or horizon- tal supply/bottom return. They cannot be used on units with power exhaust.

BAROMETRIC RELIEF DAMPER

This damper accessory can be used to relieve internal air pressure on units with an economizer but no power exhaust. This accessory includes a rain hood, a bird screen and a fully assembled damper. With bottom duct connections, the damper should be mounted over the opening in the return air panel. With horizontal ductwork, the accessory should be mounted on the return air duct.

ECONOMIZER / POWER EXHAUST RAIN HOODS

A rain hood accessory must be used on units with an economizer, a motorized damper, or a combined econ- omizer with power exhaust option. These accessories include all the hood panels, the necessary components and hardware for field assembly.

HIGH SPEED DRIVE

A smaller blower pulley and a shorter belt increase the speed of the supply air blower for applications with a higher CFM and/or static pressure requirement.

LOW AMBIENT CONTROLS TO 0°F

An autotransformer and a thermostat maintain stable system operation by reducing the speed of the con- denser fan motor at low outdoor temperatures. The kit
