This is a wall-sleeve heat pump and backup-heat system for hotel rooms, apartments, additions, or offices where central ductwork isn't an option. It's built for property managers and homeowners who need self-contained, per-room heating and cooling in a single chassis.
The HEH123J50AXXX is a 230/208V packaged terminal heat pump built for hospitality rooms, multi-family units, and room additions where ductwork isn't practical. The compressor-driven heat pump handles both cooling and primary heating, with a 5.0/4.1 kW electric heat strip providing backup heat when outdoor temperatures drop below the heat pump's effective range. 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.
- Wall sleeve: fits the industry-standard 42 in wide x 16-1/16 in high opening (WS900E / WS900QW series, 14 in depth). Wall sleeve is sold separately and is NOT included with this unit.
- Exterior architectural grille (SGK/AGK/PGK series): NOT included — sold separately.
- Voltage: 230/208V. Electric heat draws 22.1/20.0 total amps; MCA 27.6A; MOP 30A.
- Power cord: factory-installed 6-30P NEMA plug with LCDI device per UL 484 (all units under 250V ship with LCDI cords).
- Not compatible with 115V circuits.
- Not compatible with 265V circuits. The 265V commercial sibling of this chassis is the Amana HEH124J, which requires a dedicated Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect switch PSHW04A (not included) — this unit does not use that hardware and should not be hardwired as a 265V replacement.
- Not a drop-in replacement for non-standard or custom sleeve openings — verify rough-opening dimensions before ordering.
Condensate management is the most common callback on PTHP installs in wood-frame and CMU walls alike. The friction point: installers often set the sleeve dead-level because it "looks square," which traps condensate against the drywall side of the opening instead of shedding it outdoors. Over a cooling season, that trapped moisture wicks into the surrounding framing and drywall, leading to mold and soft rot that won't show up until the interior wall panel is pulled. Pitch the sleeve 1/4 bubble toward the exterior using a torpedo level set on the sleeve's bottom rail before you drive the anchoring screws — this matches the framing diagram's rough-opening tolerance (42-1/4 in wide x 16-1/4 in minimum high) and lets gravity carry condensate out through the drain path instead of into the wall cavity. On multi-unit hospitality retrofits, document the pitch check on the property's PM punch list; it's a five-minute step that prevents a five-figure drywall claim.
Key Benefits
- Heat pump operation (COP 3.4/3.4) delivers efficient primary heating before the electric backup strip engages, reducing electric heat runtime compared to strip-only PTAC systems.
- Dehumidification rated at 1.7 pints/hr, useful for humid-climate guest rooms and additions prone to moisture buildup.
- Fresh air ventilation adjustable from 65-95 CFM for make-up air in occupied rooms.
- Dual voltage-rated performance (230V/208V) lets the same chassis serve either supply without a separate SKU.
- Factory LCDI power cord (UL 484) on the 230/208V configuration supports code-compliant plug-and-play installation without additional field wiring devices.
- R-32 refrigerant charge, consistent with current-generation Amana PTHP chassis.

Compatibility & Fitment
- Compatible with 230/208V circuits via NEMA 6-30P plug and a properly sized 30A branch circuit (MCA 27.6A, MOP 30A).
- Fits standard 42-inch x 16-1/16-inch wall sleeve openings (WS900E / WS900QW series, 14 in depth).

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This chassis fits a standard 42 in x 16-1/16 in wall sleeve opening (WS900E / WS900QW, 14 in depth). The exterior architectural grille is also sold separately.
What breaker size and plug type does this unit require?
With the 5.0/4.1 kW electric heat strip installed, this unit requires a Minimum Circuit Ampacity (MCA) of 27.6A, Maximum Overcurrent Protection (MOP) of 30A, and ships with a factory 6-30P power cord for a 230/208V circuit.
Can this be hardwired for 265V commercial applications?
No. This is a 230/208V chassis and does not support 265V operation. The 265V commercial version of this chassis is the Amana 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.
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 (System Manuals and Warranty) 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 wide x 16-1/16 in high wall sleeve opening (WS900E / WS900QW series). It is not a drop-in fit for non-standard or custom sleeve openings.
