This is a wall-sleeve air conditioner and electric heater for hotel rooms, apartments, or additions where central ductwork isn't available. It's built for property managers and electricians who need a 265V, self-contained, per-room climate control unit — and it requires a 20A dedicated circuit and a compatible Amana sub-base or hard-wire kit, not a standard household outlet.
The PTC124J35AXXX is a 265V packaged terminal air conditioner built for hospitality and multi-family properties running commercial electrical service. It pairs an 11,800 BTU cooling chassis with a single-stage 3.7 kW electric heat strip, delivering 12,600 BTU of heat at 265V. All units 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 (WS900E/WS900QW standard depth 14 in)
- Voltage: 265V — minimum 239V / maximum 292V per manufacturer voltage limits
- Total heater amps: 14.2A; MCA 17.9A; MOP 20A
- Power cord/plug: 7-20P (20A NEMA configuration)
- Wall Sleeve is NOT included — sold separately (WS900E, WS900QW, or other sleeve variant per your install).
- Exterior Architectural Grille is NOT included — sold separately (SGK, AGK, or PGK series).
- Required: Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect PSHW04A — not included, must be ordered separately for 265V installation.
- NOT compatible with 115V circuits, and NOT compatible with 230/208V circuits (the 230/208V equivalent chassis is model PTC123J — do not substitute)
- This unit does NOT ship with an LCDI power cord — LCDI protection applies only to units under 250V; this 265V model uses factory-installed cartridge-style time-delay fuses instead
- NOT a drop-in fit for non-standard sleeve openings outside 42 in x 16-1/16 in — custom/deep sleeve models required for other dimensions
On 265V hospitality retrofits, techs frequently discover the wall sleeve was set dead-level during original construction with no drainage pitch built in — a friction point that doesn't show up until the first heavy cooling season. Standing condensate on a flat sleeve floor works its way back through the wall penetration and into the drywall or sill plate long before anyone notices a leak. Set the sleeve level side-to-side but pitch it approximately 1/4 bubble toward the outside wall, and confirm the pitch with a torpedo level before securing the sleeve to framing — this is the standard referenced in Amana's own framing diagram guidance. On the electrical side, verify the 7-20P cord terminates into a matching NEMA 7-20R receptacle wired through the required Amana sub-base or PTPWHWK4 hard-wire kit; a mismatched receptacle on a 265V circuit is a fire hazard, not just a fit issue. Document both the sleeve pitch and the receptacle verification on the property's install checklist — most commercial property management standards require this before a unit is signed off for occupancy.

Compatibility & Fitment
- Compatible with 265V dedicated circuits only, via a 7-20P power cord into a matching 7-20R receptacle
- Fits industry-standard wall sleeve openings measuring 42 in wide x 16-1/16 in high
- Requires an Amana-brand sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect PSHW04A — both sold separately
- NOT compatible with 115V household circuits
- NOT compatible with 230/208V circuits — for that voltage class, the equivalent chassis is model PTC123J, not this unit
- Wall Sleeve NOT included with this chassis — order separately (WS900E, WS900QW, WS900SC, or other variant)
- Exterior Architectural Grille NOT included — order separately (SGK, AGK, or PGK series)
- NOT a drop-in fit for non-standard or oversized sleeve openings — deep sleeve variants (16-24 in and beyond) are required for those cases

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This chassis fits the industry-standard 42 in wide x 16-1/16 in high opening (WS900E/WS900QW standard depth 14 in), but you need to order the sleeve, and the exterior architectural grille, independently.
What breaker size and plug type does this unit require?
This 265V configuration with the 3.7 kW heater has an MCA of 17.9A and requires a 20A maximum overcurrent protection device (MOP). It uses a 7-20P power cord. This must land on a dedicated 265V circuit — not a 230/208V or 115V outlet.
Can this be hardwired for 265V commercial applications?
Yes. All 265V Amana PTAC models must use either an Amana-brand sub-base (PTSB4**E series) or the hard-wire kit PTPWHWK4 paired with disconnect switch PSHW04A. Neither is included with the chassis; both are ordered separately based on your installation method.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
265V circuits, sub-base wiring, and cartridge-style time-delay fuses are electrical work governed by NEC code. Installation should be performed by a licensed electrician or qualified HVAC technician. Refer to the Resources tab for the manufacturer's exact warranty conditions.
Will this fit a standard 42-inch by 16-inch wall sleeve opening?
Yes. The PTC124J 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 oversized openings — those require the deep-sleeve product line (16-24 in and up, in 1-in increments).
