Precisely sized SuctionLine Accumulator to help insure reli-able operation at unit operation features include: Puron refrigerant (R-410A) Single point electrical connections optional fully integrated SystemVu controls RTU Open controller for BACnet1,LonWorks2, Modbus3 and JohnsonControls N2 3 to 5 ton models use fixed refriger-ant metering devices and 6 tonmodels use a TXV scroll compressors with internalline-break overload protection easy access tool-less filter door.

3 Fil-ter track tilts out for filter removaland replacement. All filters are thesame size in each unitInstallation easeAll WeatherMaker units are field-convertible to horizontal airflow, whichmakes it easy to adjust to unexpectedjob-site complications. Lighter unitsmake for easy replace. Simple, fastplug-in connections to the standardintegrated unit control board (UCB).Clearly labeled connections points toreduce installation time. Also, a largecontrol box provides room to work androom to mount Carrier to maintainWith the new EcoBlue Vane Axial fansystem and direct drive ECM motor,there is no longer a need to adjust beltsor pulleys as in past designs. This freesup maintenance and installation access handles by Carrier providequick and easy access to all normallyserviced components.

4 Our no-strip screw system has superior holdingpower and guides screws into positionwhile preventing the screw from strip-ping the unit s , corrosion resistant compositedrain pan sheds water; and won t to useThe newly re-designed Unit ControlBoard by Carrier puts all connectionsand troubleshooting points in one con-venient place. Most low voltage con-nections are made to the same boardand make it easy to access it. Settingup the fan is simple by an intuitiveswitch and rotary dial rooftops have high and lowpressure switches, a filter drier, and2-in. filters BACnet is a registered trademark of ASHRAE (American Society of Heating, Re-frigerating and Air-Conditioning Engineers).
