Your Carrier Packaged Heat Pump rooftop unit (RTU) was designed by customers for customers. 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 WeatherMakert units are field--convertible to horizontal air flow which makes it easy to adjust to unexpected job site
complications. Lighter units make easy replacement. Carrier 3 -- 12.5 ton 50TCQ 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. Take accurate pressure readings by reading condenser pressure with panels on. Simply remove the black, composite
plug, route your gauge line(s) through the hole, and connect them to the refrigeration service valve(s). Now, 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.
