This is a wall-sleeve air conditioner with electric heat, built for hotel rooms, apartments, or additions where central ductwork isn't available. This particular configuration adds seacoast-grade corrosion protection, so it's suited to coastal properties dealing with salt-air exposure. It's built for property managers and homeowners who need self-contained, per-room climate control.
The PTC123J50CXXX is a packaged terminal air conditioner with electric heat, built on Amana's PTC chassis and finished with seacoast-grade corrosion protection for coastal and high-salinity environments. It's commonly specified in hospitality properties, multi-family housing, and additions where ductwork isn't practical, and it is designed to meet or exceed ASHRAE 90.1 efficiency standards. 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; do not confuse with 265V commercial models).
- Total amps with heater installed: 22.1A (230V) / 20.0A (208V). MCA: 27.6A. MOP: 30A breaker required.
- NEMA plug type: 6-30P, factory-installed cord with LCDI device per UL 484 (applies to units under 250V).
- Wall Sleeve is NOT included — order separately (WS900E, WS900QW, or seacoast-rated WS900SC).
- Exterior Architectural Grille is NOT included — order separately (SGK, AGK, or PGK series).
- Not compatible with 115V circuits.
- Not suitable for 265V hardwire-only applications. The 265V commercial sibling of this chassis is the PTC124J, which requires an Amana sub-base (PTSB4**E) or hard-wire kit (PTPWHWK4) with disconnect switch (PSHW04A) — none of this applies to the 230/208V unit described here.
- Not a drop-in replacement for non-standard or custom sleeve openings.
On seacoast installs, salt-laden air accelerates corrosion at the sleeve-to-wall seam, and standing condensate at that seam is what actually eats through drywall over time — not the salt air itself. Pitch the wall sleeve 1/4 bubble toward the exterior using a torpedo level before securing it, so condensate drains outboard onto the exterior grille rather than pooling against the interior wall cavity. Confirm the sleeve extends a minimum of 1/4 in beyond the outside wall face per the framing diagram. On the electrical side, verify the receptacle is a NEMA 6-30 configuration matched to the unit's 6-30P cord — a mismatched 5-20 or 5-30 receptacle is a common punch-list item on retrofit jobs and will not accept this plug. Document the pitch and receptacle match on the property's PM checklist; this is standard practice under NEC receptacle configuration requirements and helps property managers avoid callback visits for "AC not draining" complaints.

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This unit is designed to fit the industry-standard 42 in wide x 16-1/16 in high sleeve opening, but you will need to order a compatible sleeve (such as the WS900E, WS900QW, or the seacoast-rated WS900SC) and exterior grille separately.
What breaker size and plug type does this unit require?
With the 5.0/4.1 kW electric heat installed, this unit has an MCA of 27.6A and requires a 30A circuit breaker (MOP). It ships with a factory-installed NEMA 6-30P power cord for 230/208V service.
Can this be hardwired for 265V commercial applications?
No. This model is a 230/208V unit and is not rated for 265V circuits. The 265V commercial version of this chassis is the PTC124J, which requires an Amana sub-base (PTSB4**E series) or hard-wire kit (PTPWHWK4) with disconnect switch (PSHW04A), none of which apply to this 230/208V unit.
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 specified in the source documentation provided. Refer to the warranty PDF in the Resources tab for exact 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 outside these dimensions.
