Flexibility to suit many appli-cationsThe Carrier 62D units are designed to meet customer’s requirements for new construction, replacement opportuni-ties, and special applications. The cus-tomer can choose from vertical or hor-izontal supply configurations and over 6 supply fan motor horsepower rat-ings, with forward curved or backward inclined plenum supply fans. Supply fans may be provided with spring isolation and seismic restraints to address earthquake design requirements. The modulating heating system con-trols 3 sizes of gas heat or a wide range electric heat options. Steam or hydron-ic heating coils are also available. Also available are corrosion protec-tion packages, hot gas reheat, power exhaust, 2 or 4-in. filters, and a motor-ized outdoor air damper. Roof curbs that follow the NRCA (National Roofing Contractors Associa-tion) guidelines are available for vertical applications in 14-in. and 24-in. heights and are installed and weather-proofed by the roofing contractor. Units with horizontal connections may be either curb or slab mounted. All 62DA units bring in 100% out-door air through the outside air intake hood and do not have a return air con-nection. The 62DA units have a verti-cal supply duct opening in the bottom of the unit. All 62DB units bring in 100% out-door air through the outside air intake hood and do not have a return air con-nection. The 62DB units have a hori-zontal supply duct opening in the side of the unit. All 62DC units bring in 100% out-door air through the outside air intake hood. They also have an optional ex-haust and/or energy conservation wheel factory installed. The 62DC units have vertical supply and return duct openings in the bottom of the unit. The return air is not recirculated or mixed with the incoming outdoor air. The return air is used to transfer energy to the incoming air with the en-ergy conservation wheel and is then exhausted.

The 62DD units have a horizontal supply duct opening in the side of the unit and a vertical return duct opening in the bot-tom of the unit. The return air is not recirculated or mixed with the incom-ing outdoor air. The return air is used to transfer energy to the incoming air with the energy conservation wheel and is then exhausted.
Durable constructionCabinets are constructed of heavy gage galvanized steel with a pre-painted ex-terior finish to protect the cabinet and preserve the appearance through a long operating life. The cabinet features a double wall design with a galvanized inner liner. The double wall design is insulated with closed-cell foam which adds rigidity to the structure and resists moistureintrusion.
Quality and reliabilityAll units are run tested prior to leaving the factory to help ensure proper oper-ation and enhance life expectancy of key components. Components under-go numerous checks and inspections throughout the manufacturing process to eliminate components that do not meet Carrier’s high quality standards. Reliable, hermetic scroll compres-sors, equipped with crankcase heat-ers, are mounted on rubber isolation mounts for smooth, quiet operation.
Mechanically and electrically inde-pendent dual refrigeration circuits (size 12 and larger) provide redundancy in the event that one circuit should re-quire service. All refrigerant circuits uti-lize a thermostatic expansion valve (TXV) to ensure proper refrigerant me-tering throughout the unit’s broad op-erating envelope. The refrigeration cir-cuits are protected by filter driers spe-cifically designed for Puron® refrigerant (R-410A). Standard warranty coverage provides a one-year parts warranty, 5-year com-pressor warranty, and 5 years on the stainless steel gas heat exchanger.
Easy to install, maintain and serviceMaintaining and servicing a dedicated outdoor air unit is critical in maximiz-ing the life expectancy and efficient operation of the unit. The Carrier unit has been designed for easy access with simple maintenance procedures. Hinged access panels provide easy access to controls, fans, coils and fil-ters. Slide-out supply fan system allows easy maintenance of belts, bearings, blower wheels and motors. A dedicated vertical or horizontal de-sign does not require conversion time during the unit installation. Through the curb power connection minimizes roof penetrations. Power connections are in a protect-ed area, away from harsh environmen-tal conditions. All units feature heavy gage formed galvanized steel base rails with rigging openings to simplify han-dling and lifting at the jobsite.

Indoor air qualityThe Carrier dedicated outdoor air unit offers 2 and 4-in. filter tracks that ac-cept a variety of filter types and filter MERV ratings. The condensate drain pan is double sloped to eliminate standing water per ASHRAE (American Society of Heat-ing, Refrigerating, and Air Condition-ing Engineers) Standard 62-1089R. The drain pan is fabricated of heavy gage stainless steel to resist corrosion and is insulated on the bottom with closed cell insulation. The double wall design of the unit with galvanized interior liners allows easy cleaning of the interior surfaces.
Energy recovery The Carrier dedicated outdoor air unit may be optionally equipped with an energy recovery (enthalpy) wheel. The enthalpy wheel meets the requirements of ARI standard 1060 and is certified by ARI. This energy recovery wheel is sized to provide increased energy re-covery and humidity control based on the application requirements. The en-ergy wheel is mounted in a slide-out cassette for simplified maintenance.
Heating systemsCarrier dedicated outdoor air units may be equipped with a variety of heat sys-tem types: gas heat (natural gas or liq-uified petroleum gas), electric, steam, or hot water. Precise leaving air tem-perature control is provided via staged or modulating heat control systems. The gas heating systems are of the induced draft design that draws hot combustion gases through the heat ex-changer at the ideal rate for maximum heat transfer. Induced-draft systems are an inherently safer design than forced draft, positive pressure designs. Induced-draft designs operate the heat exchanger under negative pres-sure, helping to prevent leakage of flue gases into the supply airstream. The gas heat system utilizes a direct-spark ignition and is protected by numerous safety circuits.
Microprocessor controlThe microprocessor-based controller provides complete system control of unit operation. The controller monitors all system sensors and makesoperating decisions based upon the user’s configuration inputs. Local access to the microprocessor control is accomplished via the
BACview handheld keypad/display unit. The BACview handheld or unit-mounted keypad/display features a numeric keypad, direction keys, four programmable function keys, and a backlit LCD (liquid crystal diode) dis-play. The display is a large 4-line by 40-character display that is easy to read, even in low light conditions. In addition, the microprocessor control has the following features:• simple access to set points, time
schedules, status values, and unit configuration parameters
• supports communications with BACnet*, Modbus†, and Lon-Works** building automationprotocols
• alarm conditions are indicated via an alarm LED and an audible signal
• alarm history is recorded and may be accessed via the BACview hand-held keypad/display
• password protection• compressor minimum run time
(3 minutes) and minimum off time (5 minutes) feature
• service run test and a service diag-nostic mode

Control componentsThe 62D Series of dedicated outdoor air units use a micro-processor controller that has been specifically designed forCarrier commercial equipment. The controller monitorsthe operating conditions in the outdoor air unit and con-trols the compressors, fans, heating systems, and optionaldevices. The controller has the capability of communicat-ing with all major building automation protocols includingBACnet, Modbus, and LonWorks protocols.
Sequence of operationOperation of the dedicated outdoor air unit is based uponthe occupancy schedule that the installer or user programsinto the controller. When the building is in the Occupiedmode, the supply fan starts and the mode of operation ofthe unit is based on the outdoor-air temperature (OAT). Ifthe OAT is between 56 F and 59 F, only the supply fan willoperate, which will provide cool outdoor air to the space.
If the OAT is 60 F or greater, then the unit will operatein Cooling mode. When the OAT is between 60 F and74 F, only the first stage cooling will be energized. Whenthe OAT is greater than 74 F, then all stages of cooling willbe in operation. If the unit is equipped with hot gas reheat,then the leaving-air temperature (LAT) will be controlled to72 F. An OAT of 55 F or less will cause the unit to operate ina heating mode. When the OAT is between 55 F and 46 F,the first stage heating is energized. When the OAT is lessthan 46 F, all stages of heating will be in operation. If theunit is equipped with modulating gas heat, SCR (silicon-controlled rectifier) electric heat, hot water heat, or steamheat, the leaving-air temperature will be controlled to 72 F. The unit is also equipped with a low temperature protec-tion system. If the LAT is sensed at 40 F or less, the unitwill be turned off to protect the space from potential freez-ing conditions.
