Friedrich FRH2TY3617STANNJ Air Handler 36000 Btu/h

Product Description

The FRIEDRICH FRH2TY3617STANNJ is a multi-position air handler rated at 36,000 BTU/h (2.5 to 3 nominal tons) and designed for use with R454B refrigerant. It operates with a two-stage configuration, allowing the system to run at a lower capacity stage during moderate load conditions and ramp to full capacity when demand increases. This improves dehumidification performance and reduces short-cycling compared to single-stage equipment. The multi-position design allows installation in upflow, downflow, or horizontal orientations, giving installers flexibility in a range of residential and light commercial mechanical room layouts. Licensed HVAC technicians handle installation and commissioning of this equipment.

This air handler is suited for split-system cooling and heat pump applications where R454B refrigerant is specified. The two-stage operation pairs well with compatible two-stage or variable-speed outdoor condensing units, delivering more consistent indoor temperatures and better humidity control across a range of load conditions. The multi-position cabinet accommodates installations in utility closets, attic spaces, crawlspace horizontals, and dedicated mechanical rooms. It is appropriate for residential new construction and retrofit projects where R454B-compatible equipment is required to meet current refrigerant transition guidelines.

Key Features

• 36,000 BTU/h nominal capacity covering 2.5 to 3 ton system configurations
• Two-stage operation reduces short-cycling and improves latent heat removal
• Multi-position cabinet installs in upflow, downflow, or horizontal orientation
• R454B refrigerant compatibility aligns with current low-GWP refrigerant requirements

Compatibility

Designed as an OEM-style replacement or new-installation air handler for split-system and heat pump configurations using R454B refrigerant at 2.5 to 3 nominal tons.

Installation Notes

Installation must be performed by a licensed HVAC technician holding the appropriate EPA Section 608 certification for handling refrigerants. Disconnect and lock out all electrical power to the system before any service work begins. Confirm cabinet orientation matches the planned airflow direction before securing the unit in place. Follow the applicable mechanical and electrical codes, including local adoptions of the International Mechanical Code and NEC, for refrigerant line sizing, electrical connections, and condensate drainage.
