This is a wall-sleeve air conditioner and electric-heat unit built for hotel rooms, apartments, condos, and additions where central ductwork isn't an option. It's suited for property managers and homeowners near coastal environments who need per-room climate control with added corrosion protection against salt air.
The PMC073J35CXXX is Amana's DigiAIR Cooler PTAC platform configured for 230/208V circuits with a 3.5/3.0 kW electric heat strip and factory-added seacoast corrosion protection (feature code C), intended for coastal hospitality properties, apartment buildings, and additions where salt-air exposure accelerates coil and cabinet corrosion. This unit meets or exceeds 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: Standard 42 in wide x 16-1/16 in high (industry-standard PTAC opening)
- Voltage: 230/208V — minimum 197V / maximum 253V per Amana voltage limits
- Amperage: Total heat-mode amps 15.5/14.1A; MCA 19.5A; MOP (breaker) 20A
- NEMA Plug Type: 6-20P factory-installed power cord, ships with LCDI device per UL 484 (applies to all units under 250V)
- Wall Sleeve is NOT included — sold separately (e.g., WS900E, WS900QW, or seacoast-rated WS900SC).
- Exterior Architectural Grille is NOT included — sold separately (SGK, AGK, or PGK series).
- Not compatible with 115V circuits
- Not compatible with 265V hardwire installations — see sibling commercial model PMC074J, which requires an Amana sub-base (PTSB4**E) or hard-wire kit PTPWHWK4 with disconnect PSHW04A
- Not a drop-in replacement for non-standard or custom sleeve openings
On seacoast installs, the most common callback isn't the compressor — it's condensate finding its way behind the drywall around the sleeve. Wall sleeves must pitch 1/4 bubble toward the outside wall; check it with a torpedo level on the sleeve rail before securing, not after the unit is racked in. Skipping this step lets condensate migrate inward along the sleeve floor instead of draining outdoors, which rots framing and voids the sealed-system portion of the warranty. Confirm the receptacle is a matching NEMA 6-20R before energizing — mismatching a 6-20P cord plug to a 5-20R receptacle is a common field error that trips the LCDI device repeatedly. Verify final wiring against the NEMA Receptacle Chart and local NEC Article 550 requirements for room air conditioner branch circuits before handing the unit back to the property manager.

Compatibility & Fitment
- Compatible with 230/208V circuits via a factory-installed 6-20P NEMA plug into a matching 6-20R receptacle
- Fits standard 42-inch x 16-1/16-inch wall sleeve openings (rough framing opening approx. 42-1/4 in x 16-1/4 in minimum)
- Not compatible with 115V circuits
- Not suitable for 265V hardwire-only applications; that configuration is covered by sibling model PMC074J, which requires the Amana sub-base (PTSB4**E) or hard-wire kit PTPWHWK4 with disconnect PSHW04A — none of which are included with this unit
- Wall Sleeve NOT included — must be ordered separately (e.g., WS900E, WS900QW, WS900SC seacoast triple-protected sleeve)
- Exterior Architectural Grille NOT included — must be ordered separately (SGK, AGK, or PGK series)
- Not a drop-in replacement for non-standard or custom sleeve openings — verify existing sleeve dimensions before ordering

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This chassis requires a standard 42 in x 16-1/16 in wall sleeve opening; sleeve models such as WS900E, WS900QW, or the seacoast-rated WS900SC are purchased separately.
What breaker size and plug type does this unit require?
This 230/208V configuration with 3.5/3.0 kW electric heat has an MCA of 19.5A and requires a 20A breaker (MOP). It ships with a factory-installed 6-20P power cord for plug-and-play connection to a matching NEMA 6-20R receptacle.
Can this be hardwired for 265V commercial applications?
No. This model is built for 230/208V circuits only. It is not compatible with 265V hardwire installations. The 265V commercial version of this chassis is model PMC074J, which requires an Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect PSHW04A, sold separately, plus 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 are not stated in the available warranty summary. Refer to the warranty PDF in the Resources (System Manuals and Warranty) tab for full 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 without verification of actual dimensions.
