Icp FMA5X1800AL 1.5 Ton Wall-hung Fan Coil R454B Txv Ecm

Product Description

The INTERNATIONAL COMFORT PRODUCTS FMA5X1800AL is a wall-hung fan coil unit designed for residential and light-commercial HVAC systems. It operates on R454B refrigerant and is rated at 1.5 tons of cooling capacity. The unit features a thermostatic expansion valve (TXV) for precise refrigerant metering and an electronically commutated motor (ECM) for efficient, variable-speed airflow. With a rated airflow of 650 CFM, this fan coil is built for installations where space efficiency and modern refrigerant compatibility are both required. A licensed HVAC technician is the appropriate installer for this type of equipment.

The FMA5X1800AL is suited for wall-hung applications in residential split systems and light-commercial environments. The ECM blower motor allows for quieter, more energy-efficient operation compared to traditional PSC motors, making it a strong fit for occupied spaces where comfort and noise levels matter. The TXV ensures the refrigerant charge is managed properly across varying load conditions. This unit is factory-configured for R454B, a lower global warming potential refrigerant used in newer equipment as part of ongoing refrigerant transition requirements.

Key Features

• R454B refrigerant compatibility for compliance with current refrigerant transition standards
• 1.5-ton cooling capacity suitable for smaller residential or zone-based systems
• ECM blower motor delivers variable-speed, energy-efficient airflow at 650 CFM
• TXV refrigerant metering provides consistent performance across load conditions
• Wall-hung cabinet design conserves floor space in tight mechanical rooms or living areas

Compatibility

Designed as an OEM-style wall-hung fan coil for use in split HVAC systems configured for R454B refrigerant at 1.5-ton capacity.

Installation Notes

Installation must be performed by a licensed HVAC technician with EPA Section 608 certification due to the refrigerant handling requirements of R454B. Power down the system at the disconnect and confirm zero voltage before making any electrical connections. Ensure the wall-mounting structure is rated to support the weight of the unit before securing the cabinet. Follow all local mechanical codes and manufacturer installation instructions for refrigerant line sizing, electrical connections, and condensate drainage.
