This is a wall-sleeve air conditioner and heater for hotel rooms, apartments, or additions where central ductwork isn't available. It's built for property managers and homeowners who need self-contained, per-room climate control with a factory-installed electric heat strip.
The PTC123J50AXXX is a standard-duty PTAC with electric heat, sized for hospitality guest rooms, multifamily units, and room additions where per-room, self-contained climate control replaces central ductwork. This chassis uses R-32 refrigerant and meets or exceeds 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: industry-standard 42 in wide x 16-1/16 in high (e.g., WS900E / WS900QW series sleeves).
- Voltage: 230/208V. Voltage window per manufacturer note: minimum 197V / maximum 253V.
- Total amperage (compressor + 5.0/4.1 kW heater): 22.1/20.0A. MCA: 27.6A. MOP: 30A.
- NEMA plug type: 6-30P, factory-installed power cord.
- Ships with LCDI (Leakage Current Detection and Interruption) power cord per UL 484, standard for all units under 250V.
- Wall Sleeve is NOT included — sold separately.
- Exterior Architectural Grille is NOT included — sold separately.
- Not compatible with 115V circuits.
- Not compatible with 265V hardwire-only commercial applications. This unit does not use and should not be paired with the Amana 265V sub-base (PTSB4**E) or hard-wire kit PTPWHWK4/disconnect PSHW04A — those apply to the 265V commercial sibling chassis, PTC124J, not this model.
- Not a drop-in replacement for non-standard or custom sleeve openings — verify sleeve dimensions before ordering.
The most common callback on PTAC installs isn't the compressor — it's water intrusion at the sleeve. When you set the wall sleeve, pitch it 1/4-bubble toward the outside using a torpedo level; a level or reverse-pitched sleeve backs condensate up into the wall cavity and rots drywall from the inside out over one or two cooling seasons. Confirm the sleeve extends a minimum of 1/4 in beyond the exterior wall face so the drain path has somewhere to go. On the electrical side, this unit's 6-30P plug requires a matching NEMA 6-30R receptacle on a dedicated 30A circuit — don't force a 6-20P unit's plug into this circuit or vice versa; check the NEMA receptacle chart before rough-in, not after drywall is closed. This is standard property-management practice for hospitality retrofits: verify sleeve pitch and receptacle configuration on the same site visit so you're not sending a second truck.

Compatibility & Fitment
- Compatible with 230/208V circuits via a factory-installed 6-30P plug on a dedicated 30A circuit.
- Fits standard 42 in x 16-1/16 in wall sleeve openings (e.g., WS900E, WS900QW, WS900SC, WS900GS families).
- NOT compatible with 115V circuits.
- NOT compatible with 265V hardwire-only setups — the 265V sub-base (PTSB4**E) and hard-wire kit PTPWHWK4/disconnect PSHW04A apply only to the 265V commercial sibling, PTC124J, not to this 230/208V model.
- Wall Sleeve NOT included — order separately based on your installation depth and finish needs.
- Exterior Architectural Grille NOT included — order separately (SGK, AGK, or PGK grille families).
- NOT a drop-in fit for non-standard or custom sleeve openings — confirm rough opening dimensions before purchase.

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 sleeve opening (e.g., WS900E / WS900QW series).
What breaker size and plug type does this unit require?
This 230/208V configuration with the 5.0/4.1 kW heater draws 22.1/20.0 total amps, has an MCA of 27.6A, and requires a 30A maximum overcurrent protection device. It ships with a factory-installed 6-30P power cord.
Can this be hardwired for 265V commercial applications?
No. This is a 230/208V unit, not a 265V unit. It does not use and cannot be paired with the Amana 265V sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4/disconnect PSHW04A. If you need 265V commercial service, look at the PTC124J chassis instead.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
Exact warranty conditions, including any professional-installation requirements, are documented in the manufacturer warranty PDF. Refer to the Resources (System Manuals and Warranty) tab for the full 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 wall sleeve opening. It is not a drop-in fit for non-standard or custom-sized openings without verification.
