This is a wall-sleeve heat pump system for hotel rooms, apartments, additions, or offices where central ductwork isn't available. It's built for property managers and homeowners who need self-contained, per-room heating and cooling with a factory-installed electric heat backup for cold snaps.
The PTH123J25AXXX is an Amana packaged terminal heat pump (PTHP) built for hospitality rooms, multifamily units, and additions where a self-contained, per-room system replaces central ductwork. It combines a heat-pump compressor with a 2.5/2.1 kW electric heat strip for backup heat below the heat pump's effective range, and it meets or exceeds ASHRAE 90.1 efficiency standards. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
Critical Fit & Power Requirements
- Wall sleeve opening: industry-standard 42 in wide x 16-1/16 in high (e.g., Amana WS900E / WS900QW series).
- Voltage: 230/208V. Minimum 197V / maximum 253V per voltage limit specifications for this class.
- Amperage with electric heat: 11.2A (230V) / 10.1A (208V). MCA 14.1A. MOP (breaker size) 15A.
- Power cord/plug: factory-installed 6-15P cord with LCDI device (UL 484), for a NEMA 6-15R receptacle.
- Wall Sleeve is NOT included and must be ordered separately.
- Exterior Architectural Grille is NOT included and must be ordered separately.
- Not compatible with 115V circuits.
- Not compatible with 265V circuits or 265V sub-base/hard-wire kits — the 265V commercial sibling of this chassis is the PTH124J, which uses a different electrical configuration entirely.
- Not a drop-in replacement for non-standard or custom sleeve openings.
The technical friction on any PTHP install is condensate management — this chassis relies on the wall sleeve being pitched correctly toward the exterior, not the interior drywall. Field practice is to set the sleeve level side-to-side and pitched approximately 1/4 bubble toward the outside wall, verified with a torpedo level, before securing it in the rough opening (framed to roughly 42-1/4 in wide x 16-1/4 in minimum high). Skipping this step lets condensate migrate back into the wall cavity, leading to drywall rot and mold claims months after installation — a common warranty dispute in hospitality properties. This pitch standard, combined with confirming the sleeve extends a minimum of 1/4 in beyond the exterior wall face, is a property management best practice that prevents callbacks and protects the building envelope, not just the unit.
Key Benefits
- Heat pump operation (11,000/10,800 BTU/h heating) supplements with 2.5/2.1 kW electric heat for cold-weather backup, reducing reliance on resistance heat alone.
- EER of 11.5/11.5 and COP of 3.3/3.3 for verified cooling and heating efficiency at rated conditions.
- Dehumidification rate of 1.7 pints/hr for moisture control in occupied rooms.
- Fresh air ventilation adjustable from 65-95 CFM for make-up air in tightly sealed rooms.
- R-32 refrigerant, meeting or exceeding ASHRAE 90.1 efficiency requirements.
- Factory-installed LCDI power cord (UL 484) for plug-and-play connection on 230/208V circuits — no hardwiring required at this voltage.

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This unit fits the industry-standard 42 in wide x 16-1/16 in high sleeve opening (e.g., Amana WS900E / WS900QW series), but the sleeve and exterior grille must be ordered separately.
What breaker size and plug type does this unit require?
With the 2.5/2.1 kW electric heat strip installed, this unit has a Minimum Circuit Ampacity (MCA) of 14.1A and requires a maximum overcurrent protection (breaker) of 15A. It ships with a factory-installed 6-15P power cord for a matching NEMA 6-15R receptacle on a 230/208V circuit.
Can this be hardwired for 265V commercial applications?
No. This is a 230/208V model and is not rated for 265V. The 265V commercial version of this chassis is the PTH124J, which requires an Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect switch PSHW04A, sold separately, along with factory-installed cartridge-style time-delay fuses.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
Exact installer/licensing requirements for warranty validity are detailed in the manufacturer warranty document. [NEEDS VERIFICATION] Refer to the Resources (System Manuals and Warranty) Tab above for the full warranty terms.
Will this fit a standard 42-inch by 16-inch wall sleeve opening?
Yes. This chassis is designed for the industry-standard 42 in wide x 16-1/16 in high wall sleeve opening. It is not a drop-in fit for non-standard or custom sleeve openings without verified dimensions.
