This is a wall-sleeve air conditioner and electric-heat unit built for hotel rooms, dorms, and other commercial spaces on a 265-volt electrical circuit. It's for property managers and contractors who need a single-chassis, per-room heating and cooling solution wired for commercial 265V service — not a standard household outlet.
The PMC124J35AXXX is a 265V packaged terminal air conditioner with electric heat, sized for hospitality and multi-family properties where each room needs independent temperature control without central ductwork. The chassis meets or exceeds ASHRAE 90.1 efficiency standards for commercial PTAC equipment. 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 required: industry-standard 42 in wide x 16-1/16 in high (WS900E / WS900QW series).
- Voltage: 265V — this is a dedicated commercial circuit, not standard 115V or 230/208V household wiring.
- Total electrical load with heat: 14.2A running / 17.9A MCA, 20A MOP.
- Power cord/plug: NEMA 7-20P.
- Wall Sleeve is NOT included — order separately (WS900E, WS900QW, or another sleeve variant matched to your install).
- Exterior Architectural Grille is NOT included — order separately (SGK, AGK, or PGK series).
- Required for 265V operation: Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect switch PSHW04A — neither is included with this unit.
- Not compatible with 115V circuits.
- Not compatible with 230/208V circuits — for that voltage, see sibling model PMC123J.
- Not a drop-in fit for non-standard or custom sleeve openings outside the 42 in x 16-1/16 in standard.
On 265V PTAC replacements, techs sometimes reach for the factory LCDI cord out of habit — but that device only applies to units under 250V, and this configuration ships with a NEMA 7-20P cord requiring a hardwired sub-base or the PTPWHWK4/PSHW04A disconnect kit instead. Wiring a 265V unit into a sub-base rated for a lower voltage class, or skipping the factory-installed cartridge-style time-delay fuses, creates a real risk of nuisance tripping or fuse failure under sustained heat-strip load. Verify the sub-base model plate against the Amana PTSB4**E series chart before final hookup, and confirm the circuit sits within the 239V–292V window specified for 265V equipment. This is standard practice for NEC Article 440 compliance on commercial terminal units, and it's the kind of detail a property manager's electrical inspector will check first.

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 x 16-1/16 in sleeve opening (WS900E / WS900QW series), but the sleeve, drain kit, and exterior grille all ship as separate items.
What breaker size and plug type does this unit require?
This configuration draws 17.9A MCA with a 20A maximum overcurrent protection (MOP) rating and uses a NEMA 7-20P power cord at 265V. It requires a dedicated 265V circuit sized to a 20A breaker.
Can this be hardwired for 265V commercial applications?
Yes. All 265V Amana PTAC models must be installed with either an Amana PTSB4**E sub-base or the PTPWHWK4 hard-wire kit paired with a PSHW04A disconnect switch. Neither is included with the unit and must be ordered separately.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
265V commercial installations involve dedicated circuit wiring, sub-base or hard-wire kit selection, and factory-installed cartridge-style time-delay fuses. [NEEDS VERIFICATION - exact warranty language on licensed-installer requirement is not confirmed in the provided spec data; refer to the warranty PDF in the Resources tab].
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.
