This is a wall-sleeve heat pump for hotel rooms, apartments, condos, or additions near coastal environments where central ductwork isn't available and salt-air corrosion is a concern. It's built for property managers and homeowners who need self-contained, per-room heating and cooling with added protection against seacoast corrosion.
The PTH123J35CXXX is an Amana PTHP chassis pairing a heat pump compressor with a 3.5/3.0 kW electric heat strip for backup heating below the heat pump's effective range. It is commonly specified in hospitality, multi-family, and coastal residential additions where individual room climate control is required, and it carries Amana's seacoast corrosion-protection treatment (Feature Code C) for units installed within reach of salt air. All chassis in this family 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.
- Wall Sleeve opening required: Standard 42 in wide x 16-1/16 in high (industry-standard PTAC sleeve footprint).
- Voltage: 230/208V — operating window 197V minimum to 253V maximum.
- Total Amps with electric heat installed: 15.5/14.1A; MCA 19.5A; MOP (breaker) 20A.
- NEMA Plug: 6-20P, factory-installed cord with LCDI device per UL 484 (applies to all units under 250V).
- Wall Sleeve is NOT included — sold separately.
- Exterior Architectural Grille is NOT included — sold separately.
- Not compatible with 115V circuits.
- Not compatible with 265V hardwire installations — for a 265V commercial version of this chassis, see the PTH124J, which requires an Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect switch PSHW04A (not included) and factory-installed cartridge-style time-delay fuses.
- Not a drop-in fit for custom or non-standard sleeve openings — verify sleeve depth/height before ordering.
Wall sleeve pitch is the single most common callback source on PTAC/PTHP installs. The sleeve must be level side-to-side but pitched approximately 1/4 bubble toward the outside wall — check this with a torpedo level set lengthwise across the sleeve floor before securing it in the rough opening. Getting this pitch wrong lets condensate migrate back toward the interior wall cavity instead of draining outdoors, which over months of heat-pump cooling cycles leads to drywall staining, mold growth, and rot inside the wall — problems that show up long after the installer has left the site. This is a documented framing requirement (rough opening approx. 42-1/4 in wide x 16-1/4 in minimum high, sleeve extending a minimum of 1/4 in beyond the exterior wall face), not a matter of installer preference. For hospitality properties running multiple units, building this pitch check into your standard commissioning checklist is a property-management best practice that avoids repeat water-damage service calls across an entire floor or wing.

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This unit is designed to install into an industry-standard 42 in x 16-1/16 in wall sleeve opening (such as the WS900E or WS900SC seacoast-protected sleeve), but the sleeve and exterior grille must be purchased as separate line items.
What breaker size and plug type does this unit require?
With the 3.5/3.0 kW electric heat installed, this unit has an MCA of 19.5 amps and requires a 20-amp breaker (MOP 20A). It ships with a factory-installed 6-20P power cord for 230/208V circuits.
Can this be hardwired for 265V commercial applications?
No. This model (PTH123J35CXXX) is a 230/208V unit and is not rated for 265V circuits. 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 switch PSHW04A, sold separately, along with 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] - Installer licensing requirements for warranty validity are not confirmed in the provided specification and warranty badge data. Refer to the full warranty document in the Resources tab for exact installation and registration requirements.
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-depth sleeve openings without selecting the appropriate deep or custom sleeve variant.
