This is a wall-sleeve heat pump 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 electric heat backup for cold-snap days.
The PTH123J50AXXX is Amana's standard-model PTHP chassis, combining a heat-pump compressor with a 5.0/4.1 kW electric heat strip for supplemental heating below the heat pump's effective range. It is suited to hospitality guest rooms, multifamily housing, and additions where a heat pump's efficiency is preferred over resistance-only heat. Amana PTAC/PTHP chassis are built to meet or exceed 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: Standard 42 in wide x 16-1/16 in high (WS900E / WS900QW series sleeves)
- Voltage: 230/208V — compatible with 230V or 208V single-phase circuits (min 197V / max 253V)
- Total Amps with electric heat: 22.1A (230V) / 20.0A (208V); MCA 27.6A; MOP 30A
- Power cord/plug: NEMA 6-30P, factory-installed LCDI cord per UL 484 (applies to all units under 250V)
- Wall Sleeve is NOT included — sold separately.
- Exterior Architectural Grille is NOT included — sold separately (SGK, AGK, or PGK series).
- Not compatible with 115V circuits
- Not compatible with 265V circuits or the 265V sub-base/hard-wire kit; for 265V commercial applications, use the PTH124J chassis instead
- Not a drop-in fit for non-standard or custom sleeve openings — verify rough opening dimensions before ordering
Key Benefits
- Heat pump operation (11,000/10,800 BTU/h) for efficient heating above balance point, backed by 5.0/4.1 kW electric heat for cold-weather supplement
- EER of 11.5/11.5 and COP of 3.3/3.3 across both voltage ratings
- Dehumidification rate of 1.7 pints/hr for guest comfort in humid climates
- Built-in fresh air ventilation, 65-95 CFM, for make-up air without a separate system
- R-32 refrigerant chassis meeting or exceeding ASHRAE 90.1 efficiency standards
- Net weight of 108 lb keeps the chassis manageable for single-tech swap-outs in occupied rooms

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This unit is designed to fit the industry-standard 42 in wide x 16-1/16 in high sleeve opening (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 5.0/4.1 kW electric heat strip installed, this unit requires a Minimum Circuit Ampacity (MCA) of 27.6A, a Maximum Overcurrent Protection (MOP) of 30A, and uses a NEMA 6-30P power cord and plug. Confirm your receptacle is wired to match a 6-30R before installation.
Can this be hardwired for 265V commercial applications?
No. This model is a 230/208V unit and is not compatible with 265V circuits. 265V applications require the 265V-rated PTH124J commercial sibling chassis paired with an Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect switch PSHW04A, sold separately.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
[NEEDS VERIFICATION] - installer licensing requirements for warranty validity are not specified in the provided spec data. Refer to the Product Warranty document in the Resources tab for exact installation requirements.
Will this fit a standard 42-inch by 16-inch wall sleeve opening?
Yes. This chassis fits the industry-standard 42 in wide x 16-1/16 in high wall sleeve opening (WS900E / WS900QW standard sleeves). It is not a drop-in fit for non-standard or custom sleeve openings without verifying dimensions first.
