Your Carrier rooftop unit (RTU) was designed by customers for customers. With no--strip screw collars, handled access
panel s, 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; no special adapter curbs or kits are necessary.
Convertible airflow design makes it easy to adjust to unexpected job--site complications. Lighter units make easy
replacement. Carrier 3--12.5 ton 50TC 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, c omposite
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, master terminal board by Carrier puts all your connections and troubleshooting points in one
convenient place, standard. Most low voltage connections are m ade to the same board and make it easy to find what you’re
looking for a nd easy to access it. Carrier rooftops have high and low pr essure switches, a filter drier, and 2” (51mm) filters
standard.
