Outdoor sound data is measured in accordance with AHRI Standard 270.2. 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 270.MINIMUM - MAXIMUM AIRFLOW RATINGS (CFM) — COOLING UNITS AND ACCESSORY ELECTRIC HEATCOOLING50FC UNITMINIMUMAIRFLOW CFM(CFM [L/s])MINIMUM2-SPEED AIRFLOWLOW SPEED(CFM [L/s])50FC*M071800 [846]1200 [564]ELECTRIC HEAT*MINIMUM2-SPEEDAIRFLOWHIGH SPEED(CFM [L/s])1800 [846]MAXIMUMAIRFLOW CFM(CFM [L/s])MINIMUMAIRFLOW CFM(CFM [L/s])MAXIMUMAIRFLOW CFM(CFM [L/s])3000 [1410]1800 [846]3000 [1410]* Electric heat modules are available as field-installed accessories for 50FC units.5

Options and accessories (cont)Factory-installed optionsEconomizer (dry-bulb or enthalpy)Economizers save money. They bring in fresh, outside airfor ventilation; and provide cool, outside air to cool yourbuilding. This is the preferred method of low-ambient cooling. When coupled to CO2 sensors, economizers can provide even more savings by coupling the ventilation air toonly that amount required.Economizers are available, installed and tested by the factory, with either enthalpy or dry-bulb temperature inputs.Additional sensors are available as accessories to optimizethe economizers. Economizers include a powered exhaustsystem to help equalize building pressures.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. Economizers can be factoryinstalled or easily field-installed.Unit mounted 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, theCO2 levels decrease, and the sensor appropriately closesthe economizer. This intelligent control of the ventilationair, called demand controlled ventilation (DCV), reducesthe overall load on the rooftop, saving money. It is alsoavailable as a field-installed accessory.Smoke detector (supply and/or return air)Trust the experts. Smoke detectors make your applicationsafer and your job easier. Carrier smoke detectors immediately shut down the rooftop unit when smoke is detected.They are available, installed by the factory, for supply air,return air, or both.Thru-the-base connectionsThru-the-base connections, available as a factory option,are necessary to ensure proper connection and seal whenrouting wire and piping through the rooftop’s basepan andcurb. These couplings eliminate roof penetration andshould be considered for main power lines, as well as control power.Hinged access panelsAllows access to unit’s major components with specificallydesigned hinged access panels. Panels are filter, controlbox access indoor fan motor access.8Cu/Cu (indoor) coilsCopper fins and copper tubes are mechanically bonded tocopper tubes and copper tube sheets. A polymer strip prevents coil assembly from contacting the sheet metal coilpan to minimize potential for galvanic corrosion betweencoil and pan.E-coated (outdoor and indoor) coilsA flexible epoxy polymer coating uniformly applied to allcoil surface areas without material bridging between fins.Coating process shall ensure complete coil encapsulationof tubes, fins and headers.Pre-coated outdoor coilsA durable epoxy-phenolic coating to provide protection inmildly corrosive coastal environments. The coating minimizes galvanic action between dissimilar metals. Coating isapplied to the aluminum fin stock prior to the fin stampingprocess to create an inert barrier between the aluminum finand copper tube.Condenser coil hail guardSleek, louvered panels protect the condenser coil from haildamage, foreign objects, and incidental contact.Single enthalpy sensorPrevents the wheel from rotating if the outside air conditions are acceptable for free cooling. Both exhaust andsupply blowers will remain on.Non-fused disconnectThis OSHA-compliant, factory-installed, safety switchallows a service technician to locally secure power to therooftop. When selecting a factory-installed non-fused disconnect, note they are sized for the unit as ordered fromthe factory. The sizing of these do not accommodate fieldinstalled items such as power exhaust devices, etc. If fieldinstalling electric heat with factory-installed non-fused disconnect switch, a single point kit may or may not berequired.MERV-8 return air filtersThis factory option upgrades the return air filters fromstandard unit filters to high efficiency MERV-8 filters. Nonwoven MERV-8 filter media with high strength, moistureresistant frame. Filter media is securely fasted inside the filter frame on all four sides.
Field-installed accessoriesFilter maintenance indicatorWhen the optional factory-installed filter maintenance indicator is used, a factory-installed differential pressure switchmeasures pressure drop across the outside air filter andactivates a field-supplied dry contact indicator when thepressure differential exceeds the adjustable switch setpoint.Condenser coil hail guardSleek, louvered panels protect the condenser coil from haildamage, foreign objects, and incidental contact. This canbe purchased as a factory-installed option or as a fieldinstalled accessory.Differential enthalpy sensorThe differential enthalpy sensor is comprised of an outdoorand return air enthalpy sensors to provide differentialenthalpy control. The sensor allows the unit to determine ifoutside air is suitable for free cooling.Wall or duct mounted CO2 sensorThe IAQ sensor shall be available in duct or wall mount.The sensor provides demand ventilation indoor air quality(IAQ) control.Phase monitor protectionThe Phase Monitor Control will monitor the sequence ofthree phase electrical system to provide a phase reversalprotection; and monitor the three phase voltage inputs toprovide a phase loss protection for the three phase device.It will work on either a Delta or Wye power connection.Winter start kitThe winter start kit by Carrier extends the low ambientlimit of your rooftop to 25 F (–4 C). The kit bypasses thelow pressure switch, preventing nuisance tripping of thelow pressure switch. Other low ambient precautions maystill be prudent.Low ambient controllerThe low ambient controller is a head pressure controller kitthat is designed to maintain the unit’s condenser headpressure during periods of low ambient cooling operation.This device should be used as an alternative to economizerfree cooling when economizer usage is either notappropriate or desired. The low ambient controller willeither cycle the outdoor fan motors or operate them atreduced speed to maintain the unit operation, dependingon the model. This controller allows cooling operationdown to –20 F (–29 C) ambient conditions.Roof curb 14-in. (356 mm) or 24-in. (610 mm)Full perimeter roof curb with exhaust capability providesseparate air streams for energy recovery from the exhaustair without supply air contamination.Filter status indicator accessoryMonitors static pressure across supply and exhaust filtersand provides indication when filters become clogged.Power exhaustSuperior internal building pressure control. This fieldinstalled accessory may eliminate the need for costly, external pressure control fans.Manual OA DamperManual outdoor air dampers are an economical way tobring in ventilation air. The dampers are available in 25%and 50% versions.NOTE: See application tip “ROOFTOP-18-01” prior touse of this damper on 07 size models.Motorized 2-Position DamperThe 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 infiltration.NOTE: See application tip “ROOFTOP-18-01” prior touse of this damper on 07 size models.Electric HeatersCarrier offers a full-line of field-installed accessory heaters.The heaters are very easy to use, install and are all preengineered and certified.Time 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 after stopping. Not required with RTU Open controller, or authorized commercial thermostats.Power exhaust with barometric reliefSuperior internal building pressure control.
