Filter track tiltsout for filter removal and replace-ment. All filters are the same size ineach unitInstallation easeAll WeatherMaker units are field-con-vertible to horizontal airflow, whichmakes it easy to adjust to unexpectedjob-site complications.

3 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. 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.
