50FC 3-6T WeatherMaker Rooftop AC Only or w/Electric Heat

The New Carrier WeatherMaker® rooftop units (RTU) with EcoBlue™ Technology were designed by customers for customers and integrate new technology to provide value added benefits never seen in this type of equipment before.

New major design features include:
Patent pending, Industry’s first efficient indoor fan system using Vane Axial Fan with electric commutated variable speed motor
Reliable fixed speed scroll compressor on 3-5 ton sizes and 2 stage scroll technology on 6 ton sizes
Upgraded unit control board with intuitive indoor fan adjustment
Reliable copper tube/aluminum fin condenser coil with 5/16-in. tubing to help reduce refrigerant charge verses prior designs
New outdoor fan system with rugged - lightweight high impact composite fan blade
48/50FC WeatherMaker® units up to 6 tons are specifically designed to fit on Carrier roof curbs that were installed back to 1989, which makes replacement easy and eliminates the need for curb adapters or changing utility connections.

Single-stage units deliver SEERs up to 14.0. IEERs up to 15.2. All models are capable of either vertical or horizontal airflow.

The Carrier rooftop unit (RTU) was designed by customers for customers.

With "no-strip" screw collars, handled access panels, and more the unit is easy to install, easy to maintain, and easy to use. Your new 3 to 6 ton WeatherMaker Carrier rooftop unit (RTU) provides optimum comfort and control from a packaged rooftop.

Value-added features include:
Optional Humidi-MiZer® adaptive dehumidification system for improved part load humidity performance
Puron® refrigerant (R-410A)
Single point gas and electrical connections
Optional fully integrated SystemVu™ controls
RTU Open controller for BACnet1, LonWorks2, Modbus3 and Johnson Controls N2
optional fully insulated cabinet with optional foil faced insulation
3 to 5 ton models use fixed refrigerant metering devices and 6 ton models use a TXV
Scroll compressors with internal line-break overload protection
Installation ease
All WeatherMaker units are field-convertible to horizontal airflow, which makes it easy to adjust to unexpected job-site complications. Lighter units make for easy replace. Simple, fast plug-in connections to the standard integrated unit control board (UCB). Clearly labeled connections points to reduce installation time. Also, a large control box provides room to work and room to mount Carrier accessory controls.

Easy to maintain
With the new Vane Axial fan and direct drive ECM motor - there is no longer a need to adjust belts or pulleys as in past designs. This frees up maintenance and installation time.
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.
Sloped, corrosion resistant composite drain pan sheds water; and won’t rust.
On 48FC units the Carrier designed naturally draining heat exchanger, unlike positive pressure heat exchangers, does not need to be periodically, manually drained. This saves labor and maintenance expense.

Easy to use
The newly re-designed Unit Control Board by Carrier puts all connections and troubleshooting points in one convenient place. Most low voltage connections are made to the same board and make it easy to access it. Setting up the fan is simple by an intuitive switch and rotary dial arrangement. Carrier rooftops have high and low pressure switches, a filter drier, and 2-in. filters standard.

EcoBlue™ Technology
Direct drive EcoBlue Technology indoor fan system uses Vane Axial fan design and electrically commutated motors.
This new Vane Axial design over past belt drive systems has 75% fewer moving parts, uses up to 40% less energy and has no fan belts, blower bearings and shaft.

Streamlined control and integration
Carrier controllers make connecting WeatherMaker® rooftops into existing building automation systems easy. The units are compatible with conventional thermostat controls, SystemVu™ controls and Carrier RTU Open multi-protocol controller.

Operating efficiency and flexibility
The 48/50FC rooftops meet ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers) 90.1-2016, IECC1 (International Energy Conservation Code) IECC-2018 minimum efficiency requirements.

Field convertible airflow
All WeatherMaker 3 to 6 ton units are field-convertible to horizontal airflow, which makes it easy to adjust to unexpected job-site.

Comfort control
Carrier’s patented Humidi-MiZer® adaptive dehumidification system is an all-inclusive factory-installed option on gas heating/electric cooling and electric cooling/electric heat models. This system provides reliable, flexible operation to meet indoor part load sensible and latent requirements.
