Features/BenefitsCarrier’s WeatherMaker 15 to27.5 ton rooftop unit (RTU)was designed by customersfor customers. With “nostrip” screw collars, handledaccess panels, and more,we’ve made your unit reliableand easy to install, maintain,and use.Easy to installThese WeatherMaker units aredesigned for dedicated factory-supplied vertical air flow duct configurations. Designed to fit on pre-installedcurbs by another manufacturer, theseunits also fit on past designed Carrierinstalled curbs with a new certified andauthorized adapter curb. This cabinetdesign also integrates a large controlbox that gives you room to work androom to mount Carrier accessory controls.Easy to maintainEasy 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 stripping the unit’s metal. Take accuratepressure readings by reading systempressures with panels in place as compressors are strategically located toeliminate any air bypass.Easy to useThe central terminal board by Carrierputs all your connections and troubleshooting points in one convenientplace, standard. Most low voltage connections are made to the same boardand make it easy to find what you’relooking for and easy to access it.ReliableEach unit comes with precision sizedand tested scroll compressor that isinternally protected from over temperature and pressures. In addition,each refrigerant circuit is further protected with a high-pressure and lowpressure switch as well as containing aliquid line filter drier. Each unit is factory tested prior to shipment to helpensure unit operation once properlyinstalled.Key features 2-stage cooling capability with independent circuits and control. Round tube/plate fin (RTPF) available on all sizes or Novation all aluminum condenser (outdoor) coilsavailable on 17-28 sizes only. Special coil-coating also available forcoastal and industrial environments. Energy efficiency ratios (EERs) up to10.8 IEERs up to 12.0 with single speedindoor fan motor and up to 12.7with 2-speed/VFD indoor fanmotor. Gas heating efficiencies up to 81%thermal efficiency. Dedicated vertical air flow duct configuration models. Utility connections through the sideor bottom. Bottom connections arealso in an enclosed environment tohelp prevent water entry. Field supplied couplings are required. Standardized components and layout. Standardized components andcontrols make service and stockingparts easier. Scroll compressors on all units. Thismakes service, stocking parts,replacement, and troubleshootingeasier.Table of contentsPageFeatures/Benefits . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2Model Number Nomenclature . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4AHRI Capacity Ratings . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5Physical Data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7Options and Accessories . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 13Dimensions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 17Performance Data. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 33Fan Data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 44Electrical Data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 49Typical Wiring Diagrams . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 60Sequence of Operations . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 63Application Data. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 66Guide Specifications . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 682 Proven Acutrol refrigerant metering system.

Outdoor sound data is measured in accordance with AHRI standard 370.2. Measurements are expressed in terms of sound power. Do notcompare these values to sound pressure values because soundpressure depends on specific environmental factors which normally do not match individual applications. Sound power valuesare independent of the environment and therefore more accurate.3. A-weighted sound ratings filter out very high and very low frequencies, to better approximate the response of “average” human ear.A-weighted measurements for Carrier units are taken in accordance with AHRI standard 370.MINIMUM - MAXIMUM AIRFLOW RATINGS - NATURAL GAS AND PROPANE48TCMODELSIZE1720242830HEATMINIMUMLEVEL SINGLE SPEEDFAN DHIGHCOOLINGMINIMUMMINIMUM2-SPEED FAN2-SPEED FANMOTORMOTOR(AT HIGH SPEED) (AT LOW NDAL HX — Aluminum Gas Heat ExchangerSS HX — Stainless Steel Gas Heat Exchanger6AL HX HEATINGSS HX 00110001163010000165001550015000165001550015000

Options and accessories (cont)Factory-installed optionsEconomizer (dry-bulb or enthalpy)Economizers can reduce operating costs. They bring infresh, outside air for ventilation; and provide cool outsideair to cool your building. This also is the preferred methodof low ambient cooling. When coupled to CO2 sensors,economizers can limit the ventilation air to only thatamount required.Economizers are available, installed and tested by the factory, with either enthalpy or temperature dry-bulb inputs.There are also models for electro-mechanical, direct digitalcontrollers and single speed fan or 2-speed indoor fanmotors. Additional sensors are available as accessories tooptimize the economizer.Economizers include gravity controlled barometric reliefthat helps equalize building pressure and ambient air pressures. This can be a cost effective solution to prevent building pressurization. Economizers are available in ultra lowleak and low leak versions.CO2 sensorThe CO2 sensor works with the economizer to intake onlythe correct amount of outside air for ventilation. As occupants fill your building, the CO2 sensor detects their presence through increasing CO2 levels, and opens theeconomizer appropriately.When the occupants leave, the CO2 levels decrease, andthe sensor appropriately closes the economizer. This intelligent control of the ventilation air, called Demand Controlled Ventilation (DCV), reduces the overall load on therooftop, saving money.Smoke detectorsTrust the experts.
