This is a wall-sleeve heat pump system for hotel rooms, apartments, or additions near saltwater environments where central ductwork isn't available. It's built for property managers and homeowners who need self-contained, per-room heating and cooling with added protection against coastal corrosion.
The PTH123J50CXXX is a packaged terminal heat pump (PTHP) built on the Amana PTH123J chassis with Feature Code C seacoast corrosion protection, intended for hospitality properties, coastal residential units, and additions near saltwater exposure. Cooling and heating performance figures reflect AHRI-rated dual values at 230V/208V supply. 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: 230/208V. Minimum 197V / maximum 253V per manufacturer voltage limits.
- Amperage with electric heat installed: 22.1A (230V) / 20.0A (208V) total amps; MCA 27.6A; MOP (max breaker) 30A.
- NEMA plug type: 6-30P factory power cord, shipped with LCDI (Leakage Current Detection Interruption) device per UL 484, standard on all units under 250V.
- Wall Sleeve is NOT included and must be ordered separately (e.g., WS900E, WS900QW, or WS900SC for seacoast installs).
- Exterior Architectural Grille is NOT included and must be ordered separately (SGK, AGK, or PGK series).
- Not compatible with 115V circuits.
- Not for 265V hardwire-only applications — see the PTH124J (265V commercial sibling) if a 265V circuit is required.
- Not a drop-in fit for non-standard or custom sleeve openings; confirm rough opening framing before ordering.
On seacoast installs, condensate drainage failure is the most common callback, because salt-laden humidity increases sustained runoff volume compared to inland sites. Pitch the wall sleeve 1/4 bubble toward the exterior wall using a torpedo level, confirming the sleeve extends a minimum of 1/4 in beyond the outside wall face — this keeps condensate draining outward through the chassis base pan and off the building envelope instead of pooling back toward the drywall and insulation cavity. Verify final pitch with the torpedo level centered on the sleeve rail, not the chassis itself, since chassis mounting can mask a level reading. For coastal or hospitality properties, log the sleeve pitch check in the same maintenance record used for annual PTAC/PTHP filter and coil inspections — this keeps the installation aligned with property management preventive-maintenance standards and supports any future sealed-system warranty claim.

Compatibility & Fitment
- Compatible with 230/208V circuits via a NEMA 6-30P power cord (included with unit).
- Fits standard 42 in x 16-1/16 in wall sleeve openings (industry-standard PTAC/PTHP footprint).
- Seacoast-protected chassis pairs with the Amana WS900SC seacoast triple-protected sleeve for coastal installs (sleeve sold separately).
- Not compatible with 115V circuits.
- Not for 265V hardwire-only applications — that voltage class is served by the PTH124J commercial sibling, which requires a separate Amana sub-base or hard-wire kit.
- Wall Sleeve NOT included with this unit — order separately.
- Exterior Architectural Grille NOT included with this unit — order separately.
- Not a drop-in replacement for non-standard or custom sleeve openings.

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately from the PTH123J50CXXX chassis. This unit is designed to fit the industry-standard 42 in wide x 16-1/16 in high sleeve opening (e.g., Amana WS900E, WS900QW, or WS900SC for seacoast applications).
What breaker size and plug type does this unit require?
With the 5.0/4.1 kW electric heat strip installed, this unit has an MCA of 27.6A and requires a 30A maximum overcurrent protection (breaker). It uses a NEMA 6-30P power cord for 230/208V circuits.
Can this be hardwired for 265V commercial applications?
No. This model is built for 230/208V circuits and is not rated for 265V operation. The 265V commercial version of this chassis is the PTH124J, which requires an Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect PSHW04A, sold separately, along with factory-installed cartridge-style time-delay fuses. Do not attempt to wire this 230/208V unit into a 265V circuit.
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 specified in the manufacturer warranty document, not in the specification sheets used to build this listing. Refer to the Resources (System Manuals and Warranty) tab for the full warranty terms.
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 custom sleeve openings.
