With “no-strip” screw collars, handled access panels, and more we’ve made your unit easy to install, easy to maintain and easy to use.Easy to install:All WeatherMaster® units are field-convertible to horizontal air flow, which makes it easy to adjust to unexpected job-site complications. Lighter units make easy replacement. Most of Carrier’s 3-12.5 ton 48HC rooftops fit on existing Carrier curbs dating back to 1989. Also, our large control box gives you room to work and room to mount Carrier accessory controls.Easy to maintain:Easy access handles by Carrier provide quick and easy access to all normally serviced components.

Our “no-strip” screw system has superior holding power and guides screws into position while preventing the screw from stripping the unit’s metal. bmw e46 climate control unit not workingTake accurate pressure readings by reading condenser pressure with panels on. affordable auto & ac repair of tampaSimply remove the black, composite plug, route your gauge line(s) through the hole, and connect them to the refrigeration service valve(s). auto repair hillsborough ave tampaNow, you can take refrigeration system pressure readings without affecting the condenser airflow.Easy to use:The newly designed, central terminal board by Carrier puts all your connections and troubleshooting points in one convenient place, standard.

Most low voltage connections are made to the same board and make it easy to find what you’re looking for and easy to access it. Carrier rooftops have high and low pressure switches, a filter drier, and 2-in (51mm) filters standard.FEATURES AND BENEFITSSingle-stage cooling capacity control on 04 to 07 models, 2-stage cooling capacity control on 08 to 14 modelsSEER up to 15.6, EER up to 13.0IEER’s up to 13.0 with single speed indoor fan motor, and up to 14.3 with SAVt (Staged Air Volume) 2-speed/VFD indoor fan motor systemExclusive non-corrosive composite condensate pan in accordance with ASHRAE 62 Standardside or center drainGas efficiencies up to 82%Induced draft combustion designRedundant gas valve, with up to 2 stages of heatingPre-painted exterior panels and primer-coated interior panels tested to 500 hours salt spray protectionTXV refrigerant metering system on each circuitFully insulated cabinetExclusive IGC solid-state control for on-board diagnostics with LED error code designation, burner control logic and energy saving indoor fan motor delayDedicated 3-5 ton “Low NOx” models available that meet California Air Quality Management NOx requirement of 40 nangram/
