This is a wall-sleeve heat pump and backup-heat system 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 in one chassis.
The PTH153J35AXXX is a packaged terminal heat pump (PTHP) built for hospitality rooms, multifamily units, and room additions that need self-contained heating and cooling without ductwork. It combines a heat pump compressor with a 3.5/3.0 kW electric heat strip for auxiliary backup during low-ambient conditions. Performance data on this page reflects factory ratings for the 230V/208V dual-voltage configuration. 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.
- Voltage: 230/208V dual-rated. Minimum 197V / maximum 253V per manufacturer limits.
- Amperage: total amps with heater 15.5/14.1A (230V/208V); MCA 19.5A; MOP (max breaker) 20A.
- NEMA plug: 6-20P factory power cord, ships with LCDI device per UL 484 (applies to all units under 250V).
- Wall Sleeve is NOT included and must be ordered separately.
- Exterior Architectural Grille is NOT included and must be ordered separately.
- Not compatible with 115V circuits.
- Not compatible with 265V circuits — this unit is not the 265V commercial sibling PTH154J and must not be wired with a 265V sub-base or hard-wire kit.
- Not a drop-in fit for non-standard or custom sleeve openings — confirm sleeve model before ordering.
Pro-Installer Tip: Sleeve Pitch & Drainage
The technical friction on almost every PTHP callback is condensate pooling inside the sleeve rather than draining outside. Field crews sometimes level the sleeve dead flat because it "looks right" on installation day. Long-term, that flat pitch lets water back up under the chassis and wick into the surrounding drywall and subfloor, which shows up months later as swelling, mold, or a corroded chassis base pan. Prevent it by pitching the sleeve approximately 1/4 bubble toward the exterior wall, verified with a torpedo level set across the sleeve rail before the unit is ever set into place — do not eyeball it. This is standard property management practice for any PTAC/PTHP retrofit and should be documented on the install checklist alongside the framing rough-opening check (approximately 42-1/4 in wide x 16-1/4 in minimum high), since sleeves must also extend a minimum of 1/4 in beyond the exterior wall face to shed water correctly.

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This unit is designed to install into an industry-standard 42-inch wide x 16-1/16-inch high sleeve opening, but the sleeve and exterior architectural grille must be ordered separately.
What breaker size and plug type does this unit require?
This 230/208V configuration with the 3.5/3.0 kW electric heat strip has a Minimum Circuit Ampacity (MCA) of 19.5 amps and requires a Maximum Overcurrent Protection (MOP) of 20 amps. It ships with a NEMA 6-20P power cord for plug-and-play connection to a matching 20-amp receptacle.
Can this be hardwired for 265V commercial applications?
No. This is a 230/208V unit, not a 265V model. It is not compatible with 265V circuits and should not be paired with a 265V sub-base or hard-wire kit. The 265V commercial sibling of this chassis is model PTH154J, which requires an Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect switch PSHW04A.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
Electrical connection work should be performed to meet local code and NEC requirements. Refer to the manufacturer installation instructions and warranty terms in the Resources tab for specific licensing requirements in your jurisdiction. [NEEDS VERIFICATION]
Will this fit a standard 42-inch by 16-inch wall sleeve opening?
Yes. This chassis is built to the industry-standard 42-inch wide x 16-1/16-inch high sleeve dimension. It is not a drop-in fit for non-standard or custom sleeve openings without verification of the specific sleeve model.
