This is a wall-sleeve heat pump and backup-heat system for hotel rooms, apartments, additions, or offices where central ductwork isn't available. It's built for property managers and homeowners who need self-contained, per-room heating and cooling in one chassis.
The PTH073J35AXXX is a packaged terminal heat pump (PTHP) built for hospitality corridors, multi-family additions, and offices needing self-contained, per-room comfort without ductwork. It combines a heat pump compressor with a 3.5/3.0 kW electric heat strip for backup heating below the heat pump's effective range, and it is designed to meet or exceed 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.
- Wall sleeve opening: industry-standard 42 in wide x 16-1/16 in high (sleeve sold separately — see below).
- Voltage: 230/208V. Amperage with electric heat: 15.5/14.1A total, MCA 19.5A, MOP 20A.
- NEMA plug type: 6-20P, factory-installed cord.
- Wall Sleeve is NOT included. Exterior Architectural Grille is NOT included. Both must be purchased separately (e.g., WS900E/WS900QW sleeve, SGK/AGK/PGK grille families).
- Not compatible with 115V circuits.
- Not compatible with 265V circuits or 265V sub-bases/hard-wire kits. The 265V commercial sibling of this chassis is the PTH074J — do not confuse the two when ordering.
- Not a drop-in fit for non-standard or custom sleeve openings — verify rough opening dimensions (approx. 42-1/4 in wide x 16-1/4 in minimum high per framing diagram) before install.
The technical friction: on retrofit jobs, installers often set the wall sleeve dead level because that's how the framing pocket sits, but a level sleeve gives condensate nowhere to go. Long-term, standing water in the sleeve base migrates back toward the interior wall and rots the drywall or subfloor behind the unit over a heating-cooling season or two. Prevent it by pitching the sleeve approximately 1/4 bubble toward the outside wall — check it with a Torpedo Level set lengthwise on the sleeve rail before securing fasteners, per the framing guidance for this chassis. This is standard property-management practice for hospitality corridors, where a single water-damage claim behind a PTAC/PTHP sleeve costs far more than the extra five minutes spent shimming the sleeve correctly.
- Heat pump compressor with 3.5/3.0 kW electric heat strip backup — single-stage electric heat for cold-weather supplemental heating.
- COP of 3.6/3.7 and EER of 12.4/12.8 for compressor-mode heating and cooling efficiency.
- Dehumidification rate of 1.7 pints/hr in cooling mode.
- Fresh-air ventilation capability rated 65-95 CFM for make-up air in occupied spaces.
- R-32 refrigerant charge, per manufacturer catalog notes.
- Net weight of 106 lb keeps installation and sleeve-mounting manageable for a two-person crew.

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This chassis fits the industry-standard 42 in x 16-1/16 in sleeve opening (e.g., WS900E/WS900QW series), but the sleeve and exterior grille must be ordered as separate line items.
What breaker size and plug type does this unit require?
With the 3.5/3.0 kW electric heat strip installed, this unit requires a Minimum Circuit Ampacity (MCA) of 19.5A, a Maximum Overcurrent Protection (MOP) of 20A, and ships with a factory 6-20P power cord (NEMA 6-20 configuration) for 230/208V circuits.
Can this be hardwired for 265V commercial applications?
No. This model (PTH073J35AXXX) is a 230/208V unit and is not rated for 265V circuits. The 265V commercial version of this chassis is the PTH074J, which requires an Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect switch PSHW04A, none of which apply to this 230/208V model.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
Refer to the manufacturer installation and warranty documentation in the Resources tab for exact certification requirements; this listing does not assert terms beyond the published 1-Year Repair/Replace and 5-Year Parts Limited Warranty badges.
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 sleeve opening. It is not a drop-in fit for non-standard or custom-sized sleeve openings — confirm rough opening dimensions before ordering.
This unit carries the manufacturer's published 1-Year Repair/Replace warranty and 5-Year Parts Limited Warranty. Exact terms, including any distinction between residential and commercial hospitality usage limits, are defined in the manufacturer warranty PDF — refer to the "Resources (System Manuals and Warranty)" Tab above on this page for the full document before relying on these terms for a purchase decision. Ask us before you order if you're unsure which warranty terms apply to your installation type — we always reply back.
