Icp MR5H5S24AKAAA Maratherm Heat Pump 15 SEER2 R-454B

Product Description

The INTERNATIONAL COMFORT PRODUCTS MR5H5S24AKAAA is a Maratherm-branded single-stage heat pump designed for residential split-system HVAC installations. Operating on R-454B refrigerant, this unit achieves a 15 SEER2 efficiency rating, meeting current Department of Energy regional efficiency standards. The single-stage compressor delivers consistent heating and cooling output, making it a straightforward replacement or new-construction option for licensed HVAC technicians. R-454B is an A2L low-GWP refrigerant, so installers must follow applicable refrigerant-handling requirements for mildly flammable classifications before working on this equipment.

This heat pump is intended for residential split-system applications where an outdoor condensing unit pairs with a compatible air handler or furnace and coil combination. The single-stage design suits standard load-calculated residential installations and is appropriate for markets where 15 SEER2 satisfies current minimum efficiency requirements. Consult local jurisdiction guidelines to confirm compliance before installation.

Key Features

• 15 SEER2 seasonal efficiency rating meets current DOE minimum efficiency standards
• R-454B refrigerant charge — low global warming potential, A2L mildly flammable classification
• Single-stage compressor operation for reliable, consistent capacity output
• Maratherm product line from International Comfort Products (ICP)
• Outdoor condensing unit configuration for split-system installation

Compatibility

Designed as an OEM Maratherm single-stage split-system heat pump condensing unit. Compatible indoor equipment must be rated and listed for use with R-454B refrigerant and matched to the unit nominal tonnage per AHRI-certified system combinations. Verify matched-system AHRI certificates before finalizing equipment selection.

Installation Notes

Installation must be performed by an EPA Section 608-certified HVAC technician with appropriate certification to handle A2L refrigerants. Disconnect and lock out all electrical power before servicing the unit, and shut off any associated low-voltage thermostat circuits. Follow ASHRAE 15, local mechanical codes, and the manufacturer installation instructions for clearance, refrigerant line sizing, and electrical disconnect requirements. Do not use R-454B equipment with legacy R-22 or R-410A system components unless explicitly rated for cross-compatibility.
