Icp MFHMA5X18L0AA Fan Coil 1.5 Ton Ecm R454B Txv

Product Description

The INTERNATIONAL COMFORT PRODUCTS MFHMA5X18L0AA is a 1.5-ton fan coil unit from the Maratherm product line, designed for use in split-system air conditioning and heat pump applications. It operates with R454B refrigerant and includes a factory-installed TXV metering device for precise refrigerant flow control. The unit is equipped with an ECM (electronically commutated motor) fan drive, which delivers variable-speed airflow with lower energy consumption compared to PSC motors. This fan coil is installed by licensed HVAC technicians as the indoor air-handling component in a split refrigeration circuit.

The MFHMA5X18L0AA is suited for residential split-system installations requiring an indoor fan coil rated at 1.5 tons. The R454B refrigerant compatibility makes it appropriate for systems designed around lower-GWP refrigerant blends, which are increasingly specified in new residential construction and equipment replacement projects. The factory-installed TXV eliminates the need for field metering device installation, simplifying the refrigerant circuit assembly. Licensed HVAC technicians handling R454B systems will find the ECM motor and TXV combination well-suited for matched-system efficiency requirements.

Key Features

• 1.5-ton capacity fan coil for residential split-system applications
• Compatible with R454B refrigerant, a lower-GWP alternative to legacy refrigerants
• Factory-installed TXV for accurate refrigerant metering without field modification
• ECM fan motor provides variable-speed operation and reduced electrical consumption versus PSC motors
• Part of the Maratherm fan coil product line from ICP

Compatibility

Designed for use in split-system configurations requiring a 1.5-ton indoor fan coil with R454B refrigerant and TXV metering. Verify matched outdoor unit compatibility and system refrigerant charge requirements per the equipment manufacturer specifications before installation.

Installation Notes

Installation must be performed by an EPA Section 608-certified HVAC technician qualified to handle R454B refrigerant. Power down the air handler circuit and disconnect all electrical supply before servicing or connecting refrigerant lines. R454B is an A2L mildly flammable refrigerant; follow all applicable local codes and manufacturer safety guidelines for handling and system evacuation. Verify that the matched outdoor unit and the total system refrigerant charge are specified for R454B before commissioning.
