This is a wall-sleeve heat pump and backup electric heater for hotel rooms, apartments, or additions where central ductwork isn't available. It's built for property managers and commercial installers who need self-contained, per-room heating and cooling on a 265V circuit.
The HEH074J35AXXX is an Amana High-Efficiency Heat Pump (PTHP) chassis, combining compressor-driven heating and cooling with 3.7 kW electric backup heat for a 265V commercial circuit. It suits hospitality corridors, additions, and multi-family properties where a heat pump reduces reliance on resistance heat during moderate outdoor temperatures. All units referenced here meet or exceed ASHRAE 90.1 efficiency standards. 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 wide x 16-1/16 in high (industry-standard PTAC/PTHP sleeve dimension).
- Voltage: 265V. Minimum 239V / maximum 292V per Amana voltage-limit specification.
- Total amperage with 3.7 kW heater installed: 14.2A total amps, 17.9A MCA, 20A MOP.
- Power cord/plug: 7-20P (265V, 20A NEMA configuration).
- Wall Sleeve is NOT included and must be purchased separately (e.g., Amana WS900E, WS900QW, or compatible sleeve series).
- Exterior Architectural Grille is NOT included and must be purchased separately (SGK, AGK, or PGK series).
- This 265V unit requires an Amana sub-base (PTSB4**E series) or the PTPWHWK4 hardwire kit with PSHW04A disconnect switch — neither is included.
- This unit is factory-equipped with cartridge-style time-delay fuses (265V requirement) — it does NOT ship with an LCDI power cord, since LCDI cords apply only to units under 250V per UL 484.
- Not compatible with 115V circuits.
- Not compatible with 230/208V circuits — for that voltage class, see the sibling chassis HEH073J (230/208V), not this model.
- Not a drop-in fit for non-standard or custom sleeve openings.
On 265V PTHP retrofits, the most common callback is condensate weeping into the drywall below the sleeve because the opening was framed dead-level instead of pitched. Set the sleeve with a slight outward pitch — roughly 1/4 bubble on a torpedo level, sloping toward the exterior wall — so condensate drains off the back of the chassis pan rather than pooling toward the room side. Confirm pitch with the level before securing the sleeve to framing, not after drywall is patched around it. On the electrical side, verify the receptacle or sub-base is rated for the unit's actual NEMA 7-20P plug configuration before rough-in; 265V circuits are not interchangeable with 230/208V receptacles even though the sleeve opening looks identical. Cross-check the NEMA receptacle chart against the nameplate before energizing the circuit. This combination — pitch verification plus correct NEMA matching — is standard property-management practice for avoiding both water-intrusion claims and electrical mismatch service calls in hospitality corridors.
Key Benefits
- Heat pump operation delivers 6,600 BTU/h of compressor-driven heat before backup electric heat engages, reducing electric heat runtime in moderate weather.
- 13.3 EER cooling efficiency and 3.9 COP heating efficiency on the base chassis.
- 1.7 pints/hr dehumidification during cooling operation.
- Built-in ventilation capability of 65-95 CFM for fresh make-up air.
- R-32 refrigerant charge.
- 3.7 kW single-stage electric heat backup for supplemental capacity down to 12,600 BTU/h at 265V.

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This unit fits the industry-standard 42 in x 16-1/16 in sleeve opening (for example, the Amana WS900E or WS900QW sleeve series).
What breaker size and plug type does this unit require?
With the 3.7 kW electric heat installed, this unit has a Minimum Circuit Ampacity (MCA) of 17.9A, a Maximum Overcurrent Protection (MOP) of 20A, and ships with a 7-20P power cord for a 265V circuit.
Can this be hardwired for 265V commercial applications?
Yes. All 265V Amana PTHP models must be installed with an Amana sub-base (PTSB4**E series) or the PTPWHWK4 hardwire kit paired with the PSHW04A disconnect switch. Neither is included with this unit and both are sold separately.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
This is a 265V commercial unit requiring a dedicated sub-base or hardwire kit with disconnect. [NEEDS VERIFICATION - installer licensing requirement not stated in source data; refer to the warranty PDF in the Resources tab for installation 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 wide x 16-1/16 in high sleeve opening. It is not a drop-in fit for non-standard or custom sleeve openings.
