This is a wall-sleeve air conditioner and electric-heat unit built for hotel rooms, coastal condos, or additions where central ductwork isn't available. This particular configuration adds Amana's seacoast corrosion protection, so it's aimed at properties near saltwater — beachfront hotels, coastal apartment buildings, and marine-adjacent construction where standard coil coatings corrode too fast.
This configuration pairs an 11,800 BTU cooling chassis with a 3.7 kW electric heat strip on a 265V circuit, and adds Amana's seacoast corrosion protection package for coastal and marine-adjacent installs. It is built for hospitality and multi-family properties where per-room, self-contained climate control replaces central ductwork. Units 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.
Critical Fit & Power Requirements
- Wall sleeve opening: industry-standard 42 in wide x 16-1/16 in high (standard depth 14 in) — Wall Sleeve NOT included, sold separately (e.g., Amana WS900 series, or WS900SC for seacoast triple protection).
- Exterior Architectural Grille NOT included — sold separately (SGK, AGK, or PGK grille options).
- Voltage: 265V commercial circuit. Operating range 239V–292V minimum/maximum per manufacturer note.
- Total heater amps: 14.2A; MCA: 17.9A; MOP: 20A. Power cord: 7-20P.
- 265V models require a dedicated Amana sub-base (PTSB4**E series) or the PTPWHWK4 hard-wire kit with PSHW04A disconnect switch — neither is included with this chassis.
- Ships with factory-installed cartridge-style time-delay fuses (required on 265V models).
- Not compatible with 115V circuits.
- Not compatible with 230/208V circuits — for a 230/208V version of this chassis, see sibling model PTC123J.
- Not a drop-in fit for non-standard sleeve openings outside 42 in x 16-1/16 in.
On 265V hospitality retrofits, the technical friction point is almost never the chassis — it's the sub-base or hard-wire termination and the sleeve pitch working together. A sub-base that isn't seated flush, or a sleeve pitched flat instead of angled outward, lets condensate track backward into the wall cavity instead of draining outside. Set the sleeve with a torpedo level side-to-side, then pitch it roughly 1/4 bubble toward the exterior so gravity does the drainage work, not the drain kit alone. Confirm the sub-base or PTPWHWK4/PSHW04A hard-wire termination is torqued to spec and matches the unit's 7-20P plug configuration or hardwire rating before energizing the circuit — a mismatched termination on a 265V line is an electrical-fire risk, not just a nuisance callback. This is standard property-management commissioning practice for hospitality PTAC turnovers and should be documented per NEC receptacle/hardwire requirements before the room is returned to inventory.

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately from the PTAC chassis. This model fits the industry-standard 42 in wide x 16-1/16 in high sleeve opening, such as the Amana WS900 series.
What breaker size and plug type does this unit require?
This 265V configuration with the 3.7 kW heat strip has a Minimum Circuit Ampacity of 17.9A and a Maximum Overcurrent Protection (MOP) rating of 20A. It ships with a 7-20P power cord.
Can this be hardwired for 265V commercial applications?
Yes. 265V models require either an Amana PTSB4**E sub-base or the PTPWHWK4 hard-wire kit paired with the PSHW04A disconnect switch. Neither is included with the chassis and must be ordered separately.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
265V circuits and hard-wire/sub-base connections should be installed by a licensed electrician per NEC requirements. Refer to the Resources tab for exact warranty installation 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 x 16-1/16 in sleeve opening. It is not a drop-in fit for custom or non-standard openings.
Warranty & Registration
Amana backs this unit with a 1-Year Repair/Replace warranty and a 5-Year Parts Limited Warranty on covered components. Exact terms, including any distinction between residential and commercial hospitality usage, are detailed in the warranty PDF under the "Resources (System Manuals and Warranty)" tab above — refer there before installation to confirm coverage conditions apply to your specific property type.
