1 50TC50 HzPackaged Rooftop Electric Cooling to DataC08613the environmentally sound refrigerant 2 TABLE OF CONTENTSPAGEFEATURES AND NUMBER OPTIONS & CAPACITY AND PRESSURE / 50TC--*07--16 WeatherMaker Carrier rooftop unit (RTU) was designed by customers for customers. With no--stripscrew collars, handled access panels,and more we ve made your unit easy to install, easy to maintain and easy to to install:All WeatherMakertunits are field--convertible to horizontal air flow; no special adapter curbs or kits are airflow design makes it easy to adjust to unexpected job--site complications. Lighter units make easyreplacement. These Carrier 50TC rooftops fit on existing Carrier curbs dating back to 1989. Also, our large control boxgives you room to work and room tomount Carrier accessory to maintain:Easy access handles by Carrier provide quick and easy access to all normally serviced components.

2 Our no--strip screwsystem has superior holding power and guides screws into position while preventing the screw from stripping the unit smetal. Take accurate pressure readingsby reading condenser pressure with panels on. Simply remove the black, compositeplug, route your gauge line(s) through the hole, and connect them to the refrigeration service valve(s). Now, you can takerefrigeration system pressure readings without affecting the condenser to use:The newly designed, master terminal board by Carrier puts all your connections and troubleshooting points in oneconvenient place, standard. Most low voltage connections are made to the same board and make it easy to find what you relooking for and easy to access it. Carrier rooftops have high and low pressure switches, a filter drier, and 51mm (2--in.)filters AND BENEFITSSUp to 28% lighter than similar industry units.

3 Lighter rooftops make easier replacement cooling capacity control on all 07 cooling capacity control on 08--16 modelsSThese 50TC units fit on existing Carrier rooftop curbs makingthe utility connections the same. This saves time andmoney on replacement components and layout. Standardized components and controls make service and stocking parts compressors on all units. This makes service, stockingparts, replacement, and trouble--shooting convertible airflow, kW -- kW (5 -- 10 tons). Being able to convert a unit from vertical airflow tohorizontal makes it easy to overcome job site complications. kW ( ton) models require a simple supply ductcover to field convert from factory vertical to , belt--drive motor available. There s no need for field--supplied drives or for bottom or side condensate of thru--the--base or thru--the--curb electrical electrical , composite drain pan.

They bring in fresh, outside airfor ventilation; and providecool, outsideair to cool yourbuilding. This is the preferred method of low--ambientcooling. When coupled to CO2sensors, Economizers canprovide even more savings by coupling the ventilation airto only that amount are available, installed and tested by thefactory, with either enthalpy or dry--bulb temperatureinputs. There are also models for electromechanical aswell as direct digital controllers. Additional sensors areavailable as accessoriesto optimize the include gravity controlled, barometric reliefequalizes building pressure and ambient air can be a cast effective solution to prevent productivity and saves money by working withthe economizer to intake only the correct amount ofoutside air for ventilation.

8 As occupants fill your building,the CO2sensor detects their presence through increasingCO2levels, and opens the economizer the occupants leave, the CO2levels decrease, andthe sensor appropriately closes the economizer. Thisintelligent control of the ventilation air, called DemandControl Ventilation (DCV) reduces the overall load on therooftop, saving DetectorsTrust the experts. Smoke detectors make your applicationsafer and your job easier. Carrier smoke detectorsimmediately shut down the rooftop unit when smoke isdetected. They are available, installed by the factory, forsupply air, return air, or Hail GuardsSleek, louvered panels protect the condenser coil fromhail damage, foreign objects, and incidental DisconnectThis OSHA--compliant, factory--installed, safety switchallows a service technician to locally secure power to Exhaust with Barometric accessory may eliminate the need forcostly, external pressure control CCN controller regulates your rooftop s performanceto tighter tolerances and expanded limits, as well asfacilitates zoning systems and digital accessories.

The PremierLink can befactory--installed, or easily Open Multi--protocol ControllerConnect the rooftop to an existing BAS without needingcomplicated translators or adapter modules using the RTUOpen controller. This new controller speaks the 4 mostcommon building automation system languages (Bacnet,Modbus, N2, and Lonworks). Use this controller whenyou have an existing Guard II Control CircuitThis accessory protects your compressor by preventingshort--cycling in the event of some other failure, preventsthe compressor from restarting for 30 seconds afterstopping. Not required with PremierLinkr,RTUOpen,orauthorized commercial or Fan Status SwitchesUse these differential pressure switches to detect a filterclog or indoor fan motor failure.

10 When used inconjunction with a compatible unit controller/thermostat,the switches will activate an alarm to warn the 2--Position DamperThe new Carrier 2--position, motorized outdoor air damperadmits up to 100% outside air. Using reliable, gear--driventechnology, the 2--position damper opens to allowventilation air and closes when the rooftop stops, stoppingunwanted OA DamperManual outdoor air dampers are an economical way tobring in ventilation air. The dampers are available in 25%and 50% Head Pressure ControllerThe Motormaster motor controller is a low ambient, headpressure controller kit that is designed to maintain theunit s condenser head pressure during periods of lowambient cooling operation. This device should be used asan alternative to economizer free cooling not wheneconomizer usage is either not appropriate or desired.
