This is a wall-sleeve heat pump for hotel rooms, apartments, additions, or coastal-adjacent properties where central ductwork isn't available and the outdoor unit will face salt-air exposure. It's built for property managers and homeowners who need self-contained, per-room heating and cooling with added corrosion resistance.
The HEH123J35CXXX is a High-Efficiency Heat Pump (HEH) chassis PTHP unit, combining a heat pump compressor with a 3.5/3.0 kW electric heat strip for supplemental heating below the heat pump's balance point. It carries Feature Code C, Amana's seacoast corrosion-protection treatment, intended for coastal or high-salinity installations such as beachfront hospitality properties or coastal multifamily buildings. 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 (rough opening approx. 42-1/4 in wide x 16-1/4 in min. high).
- Voltage: 230/208V — compatible with dedicated 230/208V circuits only.
- Electric heat strip: 3.5/3.0 kW, single stage, 230V/208V respectively.
- Total heater amps: 15.5/14.1A; MCA: 19.5A; MOP: 20A.
- NEMA plug type: 6-20P factory-installed power cord with LCDI device (UL 484), applicable because this unit operates under 250V.
- Wall Sleeve is NOT included — sold separately (e.g., WS900E, WS900QW, or WS900SC for seacoast environments).
- Exterior Architectural Grille is NOT included — sold separately (SGK, AGK, or PGK series).
- Not compatible with 115V circuits.
- Not for 265V hardwire or sub-base applications — for a 265V commercial version of this chassis, see sibling model HEH124J, which requires an Amana sub-base (PTSB4**E) or hard-wire kit PTPWHWK4 with disconnect PSHW04A.
- Not a drop-in replacement for non-standard or custom-depth sleeve openings — verify sleeve model dimensions before ordering.
Key Benefits
- Heat pump operation with 3.4/3.4 COP delivers supplemental electric heat only when needed, reducing strip-heat runtime compared to electric-heat-only PTAC units.
- 1.7 pints/hr dehumidification rate at rated conditions supports guest comfort in humid climates.
- Fresh-air ventilation CFM range of 65-95 CFM supports make-up air needs in hotel and multifamily applications.
- Seacoast corrosion protection (Feature Code C) targets coil and cabinet longevity in salt-air environments.
- Dual-voltage rated performance (230V/208V) documented separately for cooling, heating, and heater output, simplifying spec matching to available building voltage.
- R-32 refrigerant per manufacturer catalog note.

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This chassis fits the industry-standard 42 in wide x 16-1/16 in high wall sleeve opening (e.g., WS900E, WS900QW, or the WS900SC seacoast triple-protected sleeve). The exterior architectural grille is also sold separately.
What breaker size and plug type does this unit require?
With the 3.5/3.0 kW electric heat strip installed, this unit requires a Minimum Circuit Ampacity (MCA) of 19.5A, a Maximum Overcurrent Protection (MOP) of 20A, and ships with a factory NEMA 6-20P power cord for 230/208V circuits.
Can this be hardwired for 265V commercial applications?
No. This model is rated for 230/208V only and is not for 265V circuits. The 265V commercial sibling of this chassis is the HEH124J, which requires an Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect switch PSHW04A (sold separately) and factory-installed cartridge-style time-delay fuses.
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 wall sleeve opening. It is not a drop-in fit for non-standard or custom sleeve openings without verifying dimensions against the specific sleeve model.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
[NEEDS VERIFICATION] Exact installer-licensing requirements for warranty validity are not confirmed in the provided specification data; refer to the warranty document in the Resources tab for the manufacturer's exact installation requirements.
