Introduction

•Factory Shrinkwrap – All eco2 rooftop units can be ordered from the factory with an optional factory-fresh shrinkwrap packaging. This elimi- nates the contractors worries about dirt and debris clogging up condenser coils or moisture leaking into the air handler on the units way to the job site or rigging yard.

•Demand Ventilation Option – Can be incorpo- rated into the unit to improve indoor air quality

and help manage indoor pollutants such as CO2 or other harmful airborne contaminates out of the occupied spaces for maximum comfort and safety. Activation of this sequence can easily be

accomplished using a CO2 sensor installed in the conditioned space. CO2 sensors are typically used with demand ventilation; however other sensors may be applied to control indoor con- taminants such as volatile organic compounds (VOCs).

•Smoke Purge – Is also available to evacuate smoke due to fire from a room or zone.

•Filtration – The eco2 is configured for various types of filtration to meet the different needs and requirements of today's rooftop applications, including 2-inch throwaway, pleated, carbon, and cleanable filters and 12-inch high efficiency rigid filters.

ELECTRICAL

•Single Point Power – The eco2 unit comes stan- dard with single point power connections to make installation quick and easy.

•Dual Point Power – Can be factory installed for applications that require the mechanical heating and cooling functions to be separated from the air handling functions. This enables the unit to be operated in an emergency condition while minimizing power consumption.

•Unit-Mounted Disconnect – Is available as an option to minimize time at installation of equip- ment and to reduce necessary field installed items.

SERVICE AND INSTALLATION

•Access Doors – Full-sized access doors provide easy access into the unit for routine maintenance and inspection.

The unit can be purchased with a “Both Side Access” option for additional accessibility.

•Service Valves – Oversized service valves to provide isolation and quick reclamation and charging of system refrigerant are available as an option to minimize downtime and simplify the service and repair task.

•Convenience Outlet – For maintenance tasks requiring power tools, an optional 110V GFCI power supply can power lights, drills or any other power hand tool needed.

•Factory Run-Tested – Each unit is subjected to a series of quality assurance checks as well as an automated quality control process before being run-tested. Fans and drives are balanced at the factory during testing. The factory run-test ensures safe proper operation when the unit is installed, and reduces installation and commis- sioning time.

•Gas Heat Sections – Are factory and leaked checked.

•Replaceable Core Filter Drier Option – Pro- vides a means to remove moisture, dirt and debris from the refrigeration circuit in the event it is opened.
