This is a wall-sleeve heat pump system for hotel rooms, condos, and additions where central ductwork isn't available, built with Amana's seacoast corrosion protection for coastal properties. It's designed for property managers and homeowners in coastal or high-humidity environments who need self-contained, per-room heating and cooling with added protection against salt-air corrosion.
The PTH124J35CXXX is a packaged terminal heat pump (PTHP) built on Amana's PTH124J chassis, delivering 12,000 BTU/h cooling and 11,500 BTU/h heat pump heating with a 3.7 kW electric heat strip for supplemental backup heat at 265V. The seacoast corrosion-protection package (Feature Code C) targets coastal hospitality properties, oceanfront condos, and other high-salinity environments where standard chassis coatings degrade prematurely. This chassis meets or exceeds ASHRAE 90.1 efficiency requirements. 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 (industry-standard PTAC/PTHP sleeve footprint)
- Voltage: 265V — operating range 239V minimum / 292V maximum
- Total heater amps: 14.2A; MCA: 17.9A; MOP: 20A
- Power cord/plug: NEMA 7-20P (20-amp, 265V rated)
- Wall Sleeve is NOT included. Order separately (Amana WS900E, WS900QW, or seacoast WS900SC series).
- Exterior Architectural Grille is NOT included. Order separately (SGK, AGK, or PGK series).
- This 265V unit requires an Amana sub-base (PTSB4**E series) or the PTPWHWK4 hard-wire kit with PSHW04A disconnect switch — neither is included.
- Not compatible with 115V circuits.
- Not compatible with 230/208V circuits — the 230/208V version of this chassis is the sibling model PTH123J, not this unit.
- Not a drop-in replacement for non-standard or custom sleeve openings.
On 265V seacoast installs, technicians default to standard NEMA receptacle wiring out of habit — but this chassis needs the factory cartridge-style time-delay fuses in the Amana sub-base (PTSB4**E) or the PTPWHWK4 hard-wire kit with the PSHW04A disconnect, not a plug-in LCDI cord arrangement used on sub-250V models. Skipping the correct sub-base risks nuisance fuse blows or, worse, an overcurrent event that damages the compressor winding insulation over repeated cycles. Confirm sub-base compatibility against the Amana NEMA/voltage chart in the installation manual before rough-in, and pitch the wall sleeve 1/4 bubble toward the exterior with a torpedo level to keep condensate draining outward, not into the drywall cavity. This aligns with NEC Article 440 overcurrent protection requirements for room air conditioners and standard property management commissioning checklists for coastal hospitality assets.
Key Benefits
- Heat pump operation (11,500 BTU/h) reduces reliance on electric resistance heat in moderate outdoor temperatures, with 3.7 kW backup heat for colder conditions
- EER 11.3 and COP 3.3 provide measurable cooling and heating efficiency reference points for spec comparison
- Dehumidification rate of 1.7 pints/hr supports guest comfort in humid coastal climates
- Fresh air ventilation CFM range of 65-95 allows make-up air introduction for occupied-space code compliance
- Seacoast corrosion protection package extends chassis service life in salt-air environments compared to standard-coated units
- R-32 refrigerant used in this chassis (per manufacturer catalog note)

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This unit fits a standard 42-inch x 16-1/16-inch wall sleeve opening (Amana WS900E, WS900QW, or seacoast-rated WS900SC series). The Exterior Architectural Grille is also sold separately.
What breaker size and plug type does this unit require?
This 265V configuration with the 3.7 kW electric heat strip requires a 20-amp circuit (MOP), a Minimum Circuit Ampacity (MCA) of 17.9 amps, and uses a NEMA 7-20P power cord.
Can this be hardwired for 265V commercial applications?
This unit is a 265V model and must use an Amana brand sub-base (PTSB4**E series) or the PTPWHWK4 hard-wire kit with the PSHW04A disconnect switch. Neither the sub-base nor the hard-wire kit is included with this unit and must be ordered separately.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
[NEEDS VERIFICATION] - specific installer licensing requirements for warranty validity are not confirmed in the provided source files. Refer to the warranty documentation in the Resources tab for exact terms.
Will this fit a standard 42-inch by 16-inch wall sleeve opening?
Yes. This chassis fits the industry-standard 42-inch wide x 16-1/16-inch high wall sleeve opening. It is not a drop-in fit for non-standard or custom sleeve openings.
