Icp MFHMA5X42L0CA Maratherm Fan Coil 3.5T Ecm R454B Txv

Product Description

The INTERNATIONAL COMFORT PRODUCTS MFHMA5X42L0CA is a 3.5-ton Maratherm series fan coil unit designed for split-system HVAC applications. This unit integrates an ECM (electronically commutated motor) fan, a factory-installed TXV (thermostatic expansion valve), and is configured for use with R454B refrigerant. The ECM motor delivers variable-speed airflow, reducing energy consumption compared to PSC motor-driven coils. At 162.5 pounds, this is a full-size residential or light-commercial fan coil intended for installation by licensed HVAC technicians.

The MFHMA5X42L0CA is suited for residential and light-commercial split-system cooling and heat pump applications requiring a 3.5-ton indoor air handler. The R454B refrigerant compatibility makes this unit aligned with current low-global-warming-potential refrigerant requirements. The factory-installed TXV provides precise refrigerant metering across a range of operating conditions. This coil pairs with a compatible outdoor condensing unit or heat pump to form a complete split system.

Key Features

• 3.5-ton nominal cooling capacity for mid-size residential and light-commercial applications
• ECM fan motor provides variable-speed airflow and improved efficiency over PSC designs
• Factory-installed TXV for accurate refrigerant metering without field-installed expansion hardware
• Configured for R454B, a lower-GWP refrigerant alternative to R410A
• Maratherm fan coil series from International Comfort Products (ICP)

Compatibility

Designed as an OEM-style indoor fan coil for split-system cooling and heat pump configurations requiring a 3.5-ton R454B-compatible air handler with ECM motor technology.

Installation Notes

Installation must be performed by a licensed HVAC technician familiar with R454B refrigerant handling requirements and applicable local codes. Disconnect and lock out all electrical power before any service work. Refrigerant lines must be connected, leak-tested, and evacuated per standard industry procedure before charging. Verify that the outdoor unit is rated and matched for use with R454B before completing the system installation.
