This is a wall-sleeve heat pump air conditioner and heater for hotel rooms, coastal apartments, or additions where central ductwork isn't available. It's built for property managers and homeowners in seacoast or corrosive-air environments who need self-contained, per-room climate control with a compressor-driven heat pump plus electric heat backup for colder days.
The PMH123J25CXXX is an Amana DigiAIR packaged terminal heat pump (PTHP) built for hospitality, multi-family, and light-commercial applications where a wall sleeve replaces central ductwork. This configuration carries Amana's Feature Code C seacoast corrosion-protection treatment, intended for coastal or high-salinity environments where standard-coil units degrade faster. Performance ratings referenced here (EER, COP, cooling/heating BTU) reflect ASHRAE 90.1-aligned test conditions per Amana's published catalog data. 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.
- Voltage: 230/208V (dual-rated; slashed values on the spec table are 230V/208V ratings respectively).
- Electric heat: 2.5 kW at 230V / 2.1 kW at 208V, single-stage.
- Total amps with electric heat engaged: 11.2A (230V) / 10.1A (208V). MCA: 14.1A. MOP: 15A.
- NEMA plug type: 6-15P factory power cord.
- Wall Sleeve is NOT included and must be ordered separately (e.g., WS900E, WS900QW, or seacoast-rated WS900SC).
- Exterior Architectural Grille is NOT included — order separately (SGK, AGK, or PGK grille families).
- Not compatible with 115V circuits.
- Not compatible with 265V circuits or hardwire-only sub-base configurations. The 265V commercial sibling chassis is the Amana PMH124J, which requires an Amana sub-base (PTSB4**E) or hard-wire kit PTPWHWK4 with disconnect PSHW04A — none of that hardware applies to this 230/208V unit.
- Not a drop-in fit for non-standard sleeve openings outside 42 in x 16-1/16 in.
On seacoast-protected units like this one, condensate management matters more, not less — salt-laden moisture accelerates any drywall or framing damage from a poorly pitched sleeve. When you set the wall sleeve, level it side-to-side but pitch it approximately 1/4 bubble toward the exterior wall using a torpedo level. This keeps condensate draining outdoors instead of pooling at the rear of the chassis and wicking into interior drywall over time. Confirm the sleeve extends a minimum of 1/4 in beyond the outside wall face per the framing diagram before you seal the rough opening. This is standard property-management practice for hospitality retrofits, where warranty claims on water-damaged drywall are far more expensive than the ten extra minutes it takes to check pitch with a level.
Key Benefits
- Heat pump operation delivers 10,600/10,400 BTU of compressor-driven heating (230V/208V) before electric heat backup engages, reducing electric-heat runtime compared to heat-strip-only PTAC units.
- Seacoast corrosion protection (Feature Code C) targets coastal, high-salinity installations where standard coil coatings corrode prematurely.
- Single-stage 2.5/2.1 kW electric heat backup covers colder ambient conditions when the heat pump alone can't meet load.
- Fresh air ventilation of 25-35 CFM supports make-up air needs in sealed hospitality rooms.
- R-32 refrigerant per Amana catalog documentation.
- Rated EER of 11.3/11.5 and COP of 3.3/3.3 provide a documented efficiency baseline for comparison against other PTHP chassis.

Compatibility & Fitment
- Compatible with 230/208V circuits via the included 6-15P NEMA power cord.
- Fits industry-standard 42 in wide x 16-1/16 in high wall sleeve openings (e.g., WS900E, WS900QW, or seacoast-rated WS900SC sleeves — sold separately).
- Not compatible with 115V circuits.
- Not compatible with 265V circuits; the 265V commercial sibling chassis is the Amana PMH124J, which requires a dedicated Amana sub-base (PTSB4**E) or hard-wire kit PTPWHWK4 with disconnect PSHW04A — this 230/208V unit does not use that hardware.
- Wall Sleeve is NOT included with this unit.
- Exterior Architectural Grille is NOT included with this unit.

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This unit is designed for the industry-standard 42 in wide x 16-1/16 in high sleeve opening, but you need to order a compatible sleeve (such as WS900E, WS900QW, or the seacoast-rated WS900SC) separately.
What breaker size and plug type does this unit require?
This configuration ships with a 6-15P power cord. With the 2.5/2.1 kW electric heat strip installed, the minimum circuit ampacity (MCA) is 14.1A and maximum overcurrent protection (MOP) is 15A on 230/208V.
Can this be hardwired for 265V commercial applications?
No. This is a 230/208V unit and is not rated for 265V circuits. The 265V commercial version of this chassis is the Amana PMH124J, which requires an Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect switch PSHW04A, plus factory-installed cartridge-style time-delay fuses. Do not attempt to wire this 230/208V model into a 265V circuit.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
Refer to the manufacturer warranty document in the Resources tab for exact installation and licensing requirements. [NEEDS VERIFICATION - not confirmed in provided source data]
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. It is not a drop-in fit for non-standard or undersized openings.
