This is a wall-sleeve heat pump and backup-heat system for hotel rooms, apartments, or additions near saltwater environments where central ductwork isn't available. It's built for property managers and homeowners who need self-contained, per-room heating and cooling with added corrosion protection for coastal exposure.
The HEH073J35CXXX is a high-efficiency heat pump PTHP built for hospitality rooms, additions, and multi-family units where per-room, self-contained climate control replaces central ductwork. It carries seacoast corrosion protection (Feature Code C), making it suited to coastal properties exposed to salt air, and meets or exceeds 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: Standard 42 in x 16-1/16 in (industry-standard PTAC/PTHP sleeve size)
- Voltage: 230/208V — compatible with dedicated 230/208V circuits only
- Amperage: MCA 19.5A / MOP 20A (with 3.5/3.0 kW electric heat installed)
- NEMA Plug Type: 6-20P power cord, factory-equipped with LCDI device per UL 484 (applies to all units under 250V)
- Wall Sleeve is NOT included — sold separately (e.g., WS900E, WS900QW, or seacoast-rated WS900SC).
- Exterior Architectural Grille is NOT included — sold separately (SGK, AGK, or PGK series).
- Not compatible with 115V circuits
- Not compatible with 265V hardwire-only applications — see the Amana HEH074J (265V commercial) sibling chassis, which requires a PTSB4**E sub-base or PTPWHWK4 hard-wire kit with PSHW04A disconnect (all sold separately)
- Not a drop-in replacement for non-standard sleeve openings outside 42 in x 16-1/16 in
Wall sleeves for this chassis routinely arrive level side-to-side but flat front-to-back, which lets condensate pool against the drywall side of the sleeve instead of draining outdoors. Pitch the sleeve approximately 1/4 bubble toward the exterior wall using a torpedo level before securing it in the rough opening — this keeps wash-off water moving outward instead of wicking into interior framing over a heating season. While you're at the sleeve, confirm the receptacle is wired for a NEMA 6-20R matching the unit's factory 6-20P cord; a mismatched 5-20R or 6-15R receptacle is the single most common reason these units get returned as "defective" when the cord simply won't seat. Verify circuit voltage with a multimeter against the nameplate range (197V-253V min/max for 230/208V models) before energizing. This sequence — pitch, receptacle match, voltage check — aligns with standard property management commissioning practice and keeps the installation consistent with NEC receptacle requirements for dedicated appliance circuits.
Key Benefits
- Heat pump operation delivers 6,300/6,100 BTU/h of heating (230V/208V) without relying on the electric strip for moderate outdoor temperatures, with 3.5/3.0 kW backup heat engaging only as needed
- COP of 3.9/3.9 on the heat pump cycle indicates efficient heat transfer relative to electric-resistance-only heating
- EER of 13.3/13.7 on the cooling cycle supports lower operating cost per BTU compared to lower-efficiency chassis in this family
- 1.7 pints/hr dehumidification helps manage humidity in guest rooms and living spaces during cooling season
- Built-in fresh air ventilation (65-95 CFM) supports make-up air needs in tightly sealed rooms
- Seacoast corrosion protection (Feature Code C) extends service life in coastal, high-salt-air environments

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This PTHP chassis fits the industry-standard 42 in x 16-1/16 in wall sleeve opening (e.g., Amana WS900E, WS900QW, or the seacoast-rated WS900SC), 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 configuration has an MCA of 19.5A and an MOP of 20A, using a NEMA 6-20P power cord on a dedicated 230/208V, 20-amp circuit.
Can this be hardwired for 265V commercial applications?
No. This is a 230/208V unit and is not rated for 265V circuits. The 265V commercial version of this chassis is the Amana HEH074J, which requires an Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect switch PSHW04A (sold separately) and factory-installed cartridge-style time-delay fuses.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
The unit ships with a factory-installed LCDI power cord per UL 484 for plug-and-play connection to a properly rated 230/208V, 20A circuit. Sleeve installation, framing, and any circuit work should follow local electrical code and property management standards. Refer to the Resources tab for the exact warranty terms and any installer 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 sleeve openings.
