FEATURES AND BENEFITS S Single cooling stage models are available from 3 - 10 ton. S Two cooling stage models are available from 7.5 - 15 ton. S SEER up to 13.0. S EER’s up to 11.1. S IEER’s up to 11.8 with single speed indoor fan motor and up to 12.8 with 2- speed/VFD indoor fan motor. S Up to 28% lighter than similar industry units. Lighter rooftops make easier replacement jobs. S Utility connections are the same because 3 - 12.5 ton units fit on existing Carrier rooftop curbs. This saves time and money on replacement jobs. S Standardized components and layout. Standardized components and...

FACTORY OPTIONS AND/OR ACCESSORIES Economizer (dry-bulb or enthalpy) Disconnect Switch Bracket Economizers save money. They bring in fresh, outside air for ventilation; and provide cool, outside air to cool your building. This is the preferred method of low ambient cooling. When coupled to CO2 sensors, economizers can provide even more savings by coupling the ventilation air to only that amount required. Provides a pre- engineered and sized mounting bracket for applications requiring a unit mounted fused and non- fused disconnect of greater than 100 amps. Bracket assures that no damage will...

FACTORY OPTIONS AND/OR ACCESSORIES (cont.) Opt. Humidi-MiZer Adap. Dehum. Sys. (cont.) This system expands the envelope of operation of Carrier’s WeatherMaker rooftop products to provide unprecedented flexibility to meet year round comfort conditions. The Humidi- MiZer adaptive dehumidification system has the industry’s only dual dehumidification mode setting. The Humidi- MiZer system includes two new modes of operation. The WeatherMaker 48TC**04- 16 rooftop coupled with the Humidi- MiZer system is capable of operating in normal design cooling mode, subcooling mode, and hot gas reheat mode....

FACTORY OPTIONS AND/OR ACCESSORIES (cont.) Flue Discharge Deflector Thru- the- Base Connections - The flue discharge deflector is a useful accessory when flue gas recirculation is a concern. By venting the flue discharge upwards, the deflector minimizes the chance for a neighboring unit to intake the flue exhaust (04- 14 sizes only). Thru- the- base connections, available as either an - accessory or as a factory option, are necessary to ensure proper connection and seal when routing wire and piping through the rooftop’s basepan and curb. These couplings eliminate roof penetration and should...
