This is a wall-sleeve heat pump and backup-heat system for hotel rooms, apartments, or additions 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 heat pump doing the heavy lifting on heat and an electric strip backing it up in colder conditions.
This PTH153K50AXXX is an Amana R-410A K-series packaged terminal heat pump (PTHP), suited to hospitality guest rooms, multi-family units, and room additions where per-room heating and cooling is needed without central ductwork. Amana PTAC/PTHP chassis are tested and rated in accordance with AHRI and meet or exceed ASHRAE 90.1 efficiency standards. This is a previous-generation R-410A model sold through as in-stock inventory — it is a like-for-like match for existing R-410A PTHP installations. 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: Fits the industry-standard 42 in wide x 16-1/16 in high sleeve opening (e.g., Amana WS900E / WS900QW series).
- Voltage: 230/208V — this is a residential-and-commercial voltage class, not a 265V unit.
- Amperage: With the 5.0/4.1 kW heat strip, total amps are 22.1/20.0A, MCA is 27.6A, and the circuit requires 30A maximum overcurrent protection (MOP).
- NEMA Plug Type: 6-30P factory-installed power cord.
- Power Cord Compliance: Ships with an LCDI power cord per UL 484 (applies to all units under 250V — this includes the 230/208V configuration).
- Bold Warning: The Wall Sleeve and Exterior Architectural Grille are SOLD SEPARATELY and are NOT included with this unit.
- Not compatible with 115V circuits.
- Not suitable for 265V hardwire-only applications. The 265V commercial sibling of this chassis is the Amana PTH154J — do not attempt to wire this 230/208V unit to a 265V sub-base or disconnect switch.
- Not a drop-in replacement for non-standard sleeve openings outside the 42 in x 16-1/16 in standard.
The technical friction on this chassis shows up during rough-in: installers grab a stock sleeve without checking that the drain path is pitched correctly, and separately, they mismatch the receptacle to the cord that actually ships with the unit. This PTH153K50AXXX comes with a 6-30P plug — verify the wall receptacle is wired to a NEMA 6-30R, not a lower-amp residential-style receptacle, before setting the chassis. On the sleeve side, set a 1/4-bubble pitch toward the building exterior using a torpedo level on the sleeve rail before securing it — this keeps condensate draining outward instead of pooling back toward the drywall and subfloor, which is the single most common cause of hidden water damage behind PTAC/PTHP installations. Confirm the circuit's MOP is set to 30A per the unit's electric-heat performance data (not the chassis-only 8.5A MCA figure), and document the receptacle type and breaker size on the unit's install tag — this is standard practice for property management turnover documentation and helps satisfy local electrical inspection under NEC Article 440 for room air conditioner branch circuits.
Key Benefits
- Heat pump operation reduces reliance on electric-resistance heat in moderate outdoor temperatures, with backup 5.0/4.1 kW strip heat for colder conditions.
- Rated EER of 9.9/9.9 and COP of 3.0/3.0 across the 230V/208V dual-voltage rating.
- Dehumidification rate of 4.4 pints/hour supports guest-room and living-space comfort.
- Fresh air ventilation adjustable from 65-95 CFM for make-up air control.
- Meets or exceeds ASHRAE 90.1 efficiency standards.
- R-410A refrigerant supports like-for-like replacement of existing R-410A PTHP installations without a refrigerant-type mismatch.

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), but the sleeve and exterior architectural grille must be purchased as separate items.
What breaker size and plug type does this unit require?
With the 5.0/4.1 kW electric heat strip installed, this unit has an MCA of 27.6 amps and requires a 30-amp maximum overcurrent protection (MOP) circuit. It ships with a factory-installed 6-30P power cord and plug.
Can this be hardwired for 265V commercial applications?
No. This model is a 230/208V unit only, not a 265V unit. It is not compatible with 265V circuits and should not be paired with a 265V sub-base or hard-wire kit. The 265V commercial version of this chassis is the Amana PTH154J.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
Refer to the "Resources (System Manuals and Warranty)" Tab above for the manufacturer's exact installation and warranty-validation requirements. In general, electrical connections on 30A circuits should be made or verified by a licensed electrician per local code.
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.
