This is a wall-sleeve heat pump 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 heating and cooling from one chassis.
The PTH123J35AXXX is Amana's standard PTHP chassis: a heat-pump compressor with 3.5/3.0 kW electric heat backup for supplemental capacity below the heat pump's balance point. It suits hospitality corridors, additions, and multi-family units where per-room heating and cooling with heat-pump efficiency is preferred over straight electric-resistance heat. All units in this family 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.
- Wall sleeve opening: industry-standard 42 in wide x 16-1/16 in high (rough framing opening approx. 42-1/4 in x 16-1/4 in minimum).
- Voltage: 230/208V. Amperage (with 3.5/3.0 kW heat installed): 15.5/14.1A total amps; MCA 19.5A; MOP 20A.
- Power cord / plug: 6-20P, ships with LCDI power cord per UL 484 (applies to all units under 250V).
- Wall Sleeve is NOT included and must be ordered separately (e.g., WS900E, WS900QW).
- Exterior Architectural Grille is NOT included and must be ordered separately (SGK, AGK, or PGK series).
- Not compatible with 115V circuits.
- Not compatible with 265V circuits — that voltage class is served by the PTH124J 265V commercial sibling chassis, which requires a dedicated Amana sub-base or hard-wire kit.
- Not a drop-in fit for non-standard or custom sleeve openings — verify existing sleeve dimensions before ordering.
When you set a new wall sleeve for this chassis, condensate management is the most common callback. The sleeve must pitch toward the outside wall — target 1/4 bubble on a torpedo level, measured side-to-side and front-to-back, so condensate drains outward instead of pooling against interior drywall. Skipping this pitch is the leading cause of hidden water damage behind PTAC/PTHP installs in hospitality corridors, where the failure isn't found until the wall cavity is already compromised. Confirm the sleeve extends a minimum of 1/4 in beyond the outside wall face per the framing diagram, and log the pitch check on your commissioning sheet as a property management best practice for multi-unit buildings.
Key Benefits:
- Heat pump operation delivers 11,000/10,800 BTU/h of heating at a 3.3/3.3 COP before electric heat is needed, reducing resistance-heat runtime compared to a straight PTAC.
- Dehumidification rate of 1.7 pints/hr supports guest comfort in humid climates without oversizing the cooling cycle.
- Fresh air ventilation adjustable from 65-95 CFM for make-up air in tightly sealed rooms.
- EER of 11.5/11.5 across the 230/208V dual-voltage rating supports predictable operating cost estimates at either supply voltage.
- 3.5/3.0 kW single-stage electric heat backup sized to the 20A/6-20P circuit, simplifying electrical planning for retrofit and new-construction rooms alike.

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 wall sleeve opening, but you must order a sleeve (such as the WS900E or WS900QW) and exterior grille independently.
What breaker size and plug type does this unit require?
With the 3.5/3.0 kW electric heat strip installed, this configuration has an MCA of 19.5A and requires a 20A breaker (MOP). It ships with a 6-20P power cord for a matching NEMA 6-20 receptacle.
Can this be hardwired for 265V commercial applications?
No. This model is a 230/208V unit and does not use or require the 265V sub-base or hard-wire kit. If you need a 265V hardwire-capable unit, the 265V commercial sibling for this chassis is the PTH124J, which requires an Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect PSHW04A.
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 confirmed in the provided specification data. Refer to the warranty document in the Resources tab for the manufacturer's precise installation requirements.
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-sized openings without verification.
