This document is a product specification and installation guide for a commercial-grade fan coil/air handling unit.

The Magic Aire Model HBB40ABAAAAABA7B7BAABBM is a 4.0-ton (48,000 BTU/hr) horizontal belt-drive blower coil unit designed for ceiling-suspended installation in large commercial applications. The unit represents an upgrade from the smaller HBB20 2-ton model, with the "40" designation specifying the 4.0-ton capacity and the options string "ABAAAAABA7B7BAABBM" detailing the interior assembly configuration, including a 7B7 motor/sheave drive package configured to handle the higher static air pressure requirements of a 4-ton system. Key specifications include a typical airflow range of approximately 1,600 CFM compared to 800 CFM for the 2-ton model, a wider cabinet footprint to accommodate larger blower wheels and higher-surface-area coils, and installation suitability for large commercial zones and wider common areas. The document includes comparative specifications between the HBB20 and HBB40 models, identifying differences in nominal cooling capacity, typical airflow, chassis dimensions, drive package variants, and intended installation focuses. Accompanying photographs document the unit's physical installation in basement and warehouse settings, showing ceiling-suspended mounting, ductwork connections, control systems integration, and internal electrical/mechanical components including FEC universal binary controls and Johnson Controls METASYS integration.

FCU BASEMENT Unit

The Magic Aire Model HBB40ABAAAAABA7B7BAABBM is the larger version of the previous unit, moving up to a 4.0-Ton (48,000 BTU/hr) capacity commercial-grade, Horizontal Belt-Drive

Fan Coil / Air Handling Unit.

The model breakdown for this specific configuration includes:

HBB: Represents the Magic Aire HBB Series, signifying a ceiling-suspended, Horizontal Belt-

Drive Blower Coil Unit built for commercial applications.

40: Specifies the nominal capacity or size. In this product line, 40 represents a 4.0-Ton / 48,000

BTU/hr chassis.

ABAAAAABA7B7BAABBM: This complex options string tells the factory exactly how to assemble the interior. Compared to your previous 2-ton model, this specific string alters the mechanical drive package (indicated by the 7B7 segment rather than the 6CB5 segment), matching a different motor horsepower, voltage phase, or pulley/sheave configuration to safely push the higher static air pressure needed for a 4-ton system..

Comparative Look: HBB20 vs. HBB40

Because these two units share the same underlying architecture but exist in different sizes, their fundamental capabilities scale up as detailed in the direct comparison below:

Feature / Specification

Model HBB20... (2-Ton) Model HBB40... (4-Ton)

Nominal Cooling Capacity

2.0 Tons (24,000 BTU/hr) 4.0 Tons (48,000 BTU/hr)

Typical Airflow Range

~800 CFM ~1,600 CFM

Chassis Dimensions Narrower/lighter framework Wider cabinet footprint to house larger blower wheels and higher-surface-area coils

Drive Package Variant

Equipped with a 6CB5 motor/sheave kit

Equipped with a 7B7 motor/sheave kit

Installation Focus Small commercial zones, individual office suites

Large commercial zones, wider common areas
