Icp H5H6S18AKAAA Heat Pump 16 SEER2 1-stage R-454B

Product Description

The INTERNATIONAL COMFORT PRODUCTS H5H6S18AKAAA is a single-stage residential heat pump rated at 16 SEER2, designed for both cooling and heating applications using R-454B refrigerant. This unit operates at a rated airflow of 1,900 CFM and delivers 540 CFM for both cooling and heating modes. It is a deluxe-series, single-stage system built for standard split-system installations where reliable, efficient performance is required. Licensed HVAC technicians handle installation and commissioning, ensuring proper refrigerant handling, electrical connections, and airflow balancing in compliance with local mechanical codes.

This heat pump is intended for residential split-system applications where an air handler or furnace fan coil is paired with an outdoor condensing unit. The single-stage compressor design provides straightforward operation and is well-suited for moderate-climate installations that do not require variable-capacity staging. The R-454B refrigerant charge aligns with current low-GWP refrigerant transition requirements, making this unit appropriate for new installations and code-compliant replacements in markets requiring next-generation refrigerants.

Compatibility

Designed as an OEM-matched outdoor heat pump unit for residential split-system configurations under the Heil and ICP product platforms. Compatible indoor equipment must be rated for R-454B refrigerant and confirmed via manufacturer matchup tables prior to installation.

Installation Notes

Installation must be performed by a licensed HVAC technician with EPA Section 608 certification, as R-454B is an A2L mildly flammable refrigerant requiring specific handling procedures and leak detection practices. Disconnect and lock out all electrical power before making any wiring or refrigerant connections. Local mechanical codes and the manufacturer installation manual should be consulted for setback, clearance, and electrical supply requirements. Do not use R-454B in systems not rated and listed for A2L refrigerants.
