This is a wall-sleeve heat pump for hotel rooms, apartments, or additions where central ductwork isn't available. It's built for property managers and electricians who need self-contained, per-room heating and cooling on a 265V commercial circuit.
The PTH124J50AXXX is Amana's standard-model PTHP chassis (feature code A) built for hospitality and multi-family properties running 265V commercial electrical service. It pairs a heat pump compressor rated 12,000 BTU/h cooling and 11,500 BTU/h heating with a 5.0 kW electric heat strip for supplemental heat below the heat pump's balance point. All units meet or exceed ASHRAE 90.1. 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 (WS900E/WS900QW family)
- Voltage: 265V, operating range 239V–292V
- Total amps with electric heat: 19.2A; MCA 23.9A; MOP (fuse) 25A
- Power cord: 7-30P (NEMA), factory-installed cartridge-style time-delay fuses
- Wall Sleeve is NOT included — order separately (WS900E, WS900QW, or accessory variant)
- Exterior Architectural Grille is NOT included — order separately (SGK, AGK, or PGK)
- Not compatible with 115V circuits
- Not compatible with 230/208V circuits — for that voltage, order the sibling chassis PTH123J instead
- Requires an Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect PSHW04A — neither included
- Not a drop-in fit for non-standard or custom sleeve openings
On 265V installs, the recurring callback is a plug that doesn't match the receptacle in the field — crews show up with a standard 230V NEMA configuration and this unit ships with a 7-30P cord. Confirm the sub-base and receptacle NEMA rating against the unit's cord type before rough-in, using a NEMA Receptacle Chart, not the old unit's configuration as a reference. Getting this wrong on a 265V line means an electrician has to pull new conductors or swap the sub-base after drywall is closed, which is a far more expensive fix than a five-minute chart check during the takeoff. This also matters for property management liability: mismatched voltage/plug pairings on 265V commercial circuits are the kind of finding that shows up on a fire marshal or insurance inspection under NEC receptacle configuration requirements.
Key Benefits

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 (WS900E/WS900QW family), but the sleeve, drain kit, and exterior grille all ship separately.
What breaker size and plug type does this unit require?
With the 5.0 kW electric heat installed, this configuration has an MCA of 23.9A and requires a 25A time-delay fuse (MOP). It ships with a 7-30P power cord for 265V circuits. Amps and watts listed for the compressor alone (4.9A/1,060W cooling) are not the values to size the breaker from — use the 23.9A MCA / 25A MOP figures from the electric heat performance table.
Can this be hardwired for 265V commercial applications?
Yes. All 265V models require an Amana brand sub-base (PTSB4**E series) or the PTPWHWK4 hard-wire kit paired with the PSHW04A disconnect switch. Neither the sub-base nor the hard-wire kit is included with this unit. Note this unit does not use an LCDI power cord — LCDI cords apply only to units under 250V per UL 484.
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 source files. Refer to the manufacturer warranty PDF in the Resources tab for exact 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 x 16-1/16 in sleeve opening. It is not a drop-in fit for non-standard or custom sleeve openings outside that dimension.
