The ICP FCMA5B48L0CA is a 4-ton modular fan coil unit engineered for use with R454B refrigerant in high-efficiency residential and light commercial air handling applications. Rated at 48,000 BTU/h nominal cooling capacity, this unit features a variable-speed blower motor that allows precise airflow control across a wide range of system demands. At 172 pounds and measuring 24 x 21.13 x 53.44 inches, it is sized for dedicated equipment closets, utility rooms, and modular air handler installations. A licensed HVAC technician typically handles the installation, refrigerant connections, and low-voltage control wiring.
The FCMA5B48L0CA is suited for split-system cooling and heat pump applications where R454B refrigerant is specified. The 21-inch cabinet width targets standard equipment closet footprints common in residential construction and light commercial retrofits. The variable-speed blower supports zoning systems, communicating thermostats, and multi-stage outdoor units by modulating airflow output to match system demand, improving comfort and reducing energy consumption over single-speed alternatives.
Designed for use in R454B split-system and heat pump configurations as an OEM-specified modular fan coil unit. Consult ICP engineering documentation for approved matched outdoor unit pairings and system ARI ratings.
Installation must be performed by a licensed HVAC technician holding the appropriate EPA Section 608 certification for A2L refrigerant handling, as R454B carries a mild flammability classification requiring adherence to current ASHRAE 15 and local mechanical code requirements. Power down the air handler circuit at the breaker and confirm zero voltage before making any electrical connections. Ensure the unit is properly supported and leveled per the manufacturer installation manual before connecting supply and return ductwork. Low-voltage control wiring should be routed and connected according to the system wiring diagram provided with the equipment.
