This is a wall-sleeve air conditioner and electric-heat unit built for coastal hospitality properties, apartments, and additions where central ductwork isn't available. It's designed for property managers and homeowners in seacoast environments who need self-contained, per-room climate control with added corrosion protection.
The PMC073J25CXXX is a Seacoast Protected PTAC built on Amana's PMC chassis, combining compressor cooling with a 2.5/2.1 kW electric heat strip in a single 230/208V package. It's suited to coastal hotel, motel, and multi-family properties where salt-air exposure accelerates corrosion on standard equipment, as well as inland additions needing self-contained comfort control. All units in this family meet or exceed ASHRAE 90.1 efficiency requirements. 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 sleeve).
- Voltage: 230/208V. Minimum 197V / maximum 253V per Amana voltage limits for this class.
- Amperage: Total 11.2/10.1A with electric heat active; MCA 14.1A; MOP 15A.
- Plug/Cord: 6-15P power cord, shipped with LCDI device per UL 484 (applies to all units under 250V).
- Wall Sleeve is NOT included and must be ordered separately.
- Exterior Architectural Grille is NOT included and must be ordered separately.
- Not compatible with 115V circuits.
- Not compatible with 265V hardwire or sub-base applications — for a 265V commercial version of this chassis, see sibling model PMC074J, which requires an Amana sub-base (PTSB4**E) or hard-wire kit PTPWHWK4 with disconnect PSHW04A (sold separately).
- Not a drop-in fit for non-standard or custom sleeve openings other than 42 in x 16-1/16 in.
Pro-Installer Tip
The most common callback on seacoast PTAC installs isn't the compressor — it's water intrusion at the sleeve. When you set the WS900 series sleeve into the rough opening, the framing diagram calls for the sleeve to extend a minimum of 1/4 in beyond the outside wall and pitch toward the exterior. Check that pitch with a torpedo level set to a 1/4-bubble tilt outward before you drive a single fastener; a sleeve installed level or pitched inward will pool condensate against the interior wall and rot the drywall or subfloor over a heating season, not immediately. This matters more on Seacoast-Protected units like this one because salt-air corrosion accelerates on any hardware kept chronically wet, undermining the coating's service life. Confirm the receptacle is a matching NEMA 6-15R for this unit's 6-15P cord — a mismatched receptacle is both an NEC code violation and a fire risk under sustained 11.2A draw. Document the pitch check and receptacle match on the property's install record; it's standard practice for hospitality property management to keep this paperwork for insurance and warranty audits.

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This unit fits the industry-standard 42 in wide x 16-1/16 in high sleeve opening (e.g., WS900E, WS900QW, or WS900SC for additional seacoast protection), but the sleeve and exterior grille must be ordered as separate line items.
What breaker size and plug type does this unit require?
This configuration requires a 6-15P power cord plug, a Minimum Circuit Ampacity (MCA) of 14.1A, and a Maximum Overcurrent Protection (MOP) of 15A on a 230/208V circuit.
Can this be hardwired for 265V commercial applications?
No. This is a 230/208V unit and ships with a factory-installed LCDI power cord per UL 484, which applies only to units under 250V. It is not rated for 265V circuits. The 265V commercial sibling of this chassis is the PMC074J, 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 specified in the provided source data. Refer to the warranty PDF in the Resources tab for confirmed 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. It is not a drop-in fit for non-standard or custom sleeve dimensions.
