Friedrich FPHFA36A3D Air Handler 36000 Btu R454B

Product Description

The FRIEDRICH FPHFA36A3D is a 36,000 BTU ductless air handler designed for high-efficiency residential and light commercial split-system installations. Part of the Breeze Premier line, this unit operates on 208-230 volt single-phase 60 Hz power and is factory-configured for R454B refrigerant, a low-global-warming-potential A2L refrigerant increasingly specified in new installations. An integrated A2L refrigerant sensor is included, meeting current safety requirements for mildly flammable refrigerant handling in occupied spaces. Licensed HVAC technicians handle installation and commissioning.

This air handler is suited for residential and light commercial applications where high-efficiency ductless zoning is required. The 36,000 BTU capacity serves larger zones such as open-plan living areas, commercial suites, or multi-room configurations. Its R454B compatibility positions it for new construction and replacement projects where updated refrigerant standards apply. The included A2L sensor supports code-compliant installation in jurisdictions that have adopted ASHRAE 15 or equivalent safety standards for mildly flammable refrigerants.

Key Features

• 36,000 BTU capacity for large-zone ductless split-system applications
• 208-230 volt single-phase 60 Hz electrical configuration
• R454B refrigerant rated — low-GWP A2L refrigerant compatible
• Integrated A2L refrigerant sensor included for code-compliant installations
• Part of the Breeze Premier line engineered for high energy efficiency

Compatibility

Designed as an OEM-style air handler for ductless mini-split systems using R454B refrigerant. Verify outdoor unit compatibility with the FPHFA36A3D before installation, as matching condensing unit capacity and refrigerant type are required for proper system operation.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle A2L refrigerants under applicable EPA Section 608 and local code requirements. Disconnect and lock out all electrical power before beginning any work on the air handler or associated wiring. Follow ASHRAE 15 and local mechanical codes regarding sensor placement and ventilation requirements when working with A2L refrigerants. Do not commission the system without confirming the A2L sensor is properly wired and functional.
