Coleman Single Piece Standard ECM Air Handlers

Product Description

This fan coil line offers exceptional application flexibility, suitable for upflow, downflow, horizontal right, or horizontal left configurations. All JCI Unitary Products air handlers and coils can utilize a TXV (Thermostatic Expansion Valve) for optimal performance and refrigerant control. Single-piece air handlers are available with 'Flex-coils' for field installation of an R-22 or R-410A TXV or piston to meet specific refrigerant requirements. Some models are available with a factory-installed TXV.

Key Features

• RC2 Rigid Case Construction: Provides interior endoskeleton for structural support, smooth sides, and insulation retention.
• Powder-painted: G30 galvanized steel case offers corrosion and rust creep resistance.
• MaxAlloy™ Coil: Long-life aluminum coils designed for lasting performance and efficiency.
• Quality Construction: Structural components made of Aluminum or G90 galvanized steel to prevent corrosion.
• Improved Insulation Design: Single-piece construction with no external screws minimizes thermal transmission and prevents sweating; foil-faced insulation for easy cleaning.
• Thermostatic Expansion Valve (TXV): Accessory chatleff-style TXV for easy installation and conversion to required refrigerant without brazing.
• Case Depth: 20.5" casing allows for easier attic access and fits tight applications.
• Thermoset Drain Pan: Features a positive slope for drainage, reducing potential for mold or contaminants.
• Factory Sealed: Achieves 2% or less total airflow leakage at specified test conditions for system airflow verification.
• Enhanced Filter Rack: Integrated internal filter racks accommodate 1" thick standard size filters.
• Electric Heat Kits: 6HK series of field-installed electric heat kits are available for easy installation and service.
• Cabinet Air Leakage: Less than 2.0% at 1.0 inch esp., tested per ASHRAE standard 193.
• Blowers: All models use direct-drive, standard ECM motors.

Nomenclature

Model nomenclature provides details on Product Type (A=Single Piece Air Handler), Position Motor Type (E=Multi Std ECM, V=Multi VS ECM, Z=Compact Up Std ECM), Options (C=Communications Ready, -=Standard), Nominal Unit Capacity (e.g., 18=1.5 Ton, 24=2 Ton, 36=3 Ton, 42=3.5 Ton, 48=4-Ton, 60=5-Ton), Cabinet Width (A=14.5", B=17.5", C=21.0", D=24.5"), TXV Indicator (X=no valve, BA-BF=Valve Size), Voltage (1=115-1-60, 2=208/230-1-60, 3=208/230-3-60, 4=460-3-60), Generation (1=1st Gen, 2=2nd Gen), and Style Letter (A=Style A, B=Style B).

Dimensions & Duct Connection

Diagram showing the physical layout and dimensions (A, B, C, D, E, F, G) of the air handler unit, including blower compartment, coil compartment, filter access, and refrigerant connections. A table provides specific dimensions and wiring knockout sizes for various AE models (e.g., AE18B*21, AE24B*21, AE36C*21, AE48D*21, AE60D*21).

1. All dimensions are in inches. 2. Actual size (conduit size).

Coil Technical Data

Table detailing coil specifications including model, application, refrigerant connection types, face area (sq. ft.), rows, fins per inch, coil size geometry, tube diameter, and fin type (e.g., Sine Wave) for various AE models.

1. * Factory-Installed TXV option.

Cooling Capacity

Tables provide cooling capacity data (MBH) for various entering air conditions (Dry/Wet Bulb °F) and corresponding R-410A pressures (°F/PSIG) for different air handler models (e.g., 18B, 24B, 30B, 36B, 36C, 42C, 43C, 48C, 48D, 60C, 60D). Capacity factors for rated CFM vs. actual CFM are also provided.

1. Actual capacity varies with the outdoor A/C or H/P that is used with the system. 2. Airflow is calculated for each system tonnage.

Physical & Electrical Data - Cooling Only

Tables detail physical and electrical specifications for cooling-only operation, including blower diameter/width, motor HP and RPM, voltage, full load amps, filter type and size, and shipping/operating weight for various models.

1. Field supplied.

Electrical Data - Cooling Only

Tables show Motor FLA (Full Load Amps), Minimum Circuit Ampacity, and MOP (Maximum Overcurrent Protection) for various air handler models.

1. FLA = Full Load Amps. 2. MOP = Maximum Overcurrent Protection device; must be HACR type circuit breaker or time delay fuse. Refer to the latest edition of the National Electric Code or in Canada the Canadian electrical Code and local codes to determine correct wire sizing.

Electric Heat Options & Performance

Information on electric heat kits (6HK series) and their performance data for 208/230-1-60 and 208/230-3-60 power supplies. Tables detail nominal kW, kW staging, and MBH output.

1. (0,1) - 0 = no service disconnect OR 1 = with service disconnect. 2. (1,2) - 1 = with service disconnect, no breaker jumper bar OR 2 = with service disconnect & breaker jumper bar. 3. 6HK3 = 3-Phase with terminal block connectors only, 6HK4 = 3-Phase with service disconnect. 4. For different power distributions, see conversion table on Page 5.

Electrical Data for Single Source Power Supply

Detailed tables provide electrical data for single-source power supplies (208/230-1-60 and 208/230-3-60), including heater amps, minimum circuit ampacity, and MOP for various air handler and heater models.

1. (0,1) - 0 = no service disconnect OR 1 = with service disconnect. 2. (1,2) - 1 = with service disconnect, no breaker jumper bar OR 2 = with service disconnect & breaker jumper bar. 3. MOP = Maximum Overcurrent Protection device; must be HACR type circuit breaker or time delay fuse. Refer to the latest edition of the National Electric Code or in Canada the Canadian electrical Code and local codes to determine correct wire sizing.
