This is a wall-sleeve heat pump system for hotel rooms, apartments, condos, or additions near coastal environments where central ductwork isn't available and corrosion resistance matters. It's built for property managers and homeowners who need self-contained, per-room heating and cooling with factory-applied seacoast corrosion protection.
The PTH073J35CXXX is a packaged terminal heat pump (PTHP) built on Amana's PTH073J chassis, combining a heat pump compressor with a 3.5/3.0 kW electric heat strip for auxiliary and backup heating. This configuration carries Amana's Feature Code C seacoast corrosion-protection package, intended for coastal hospitality properties, marine-adjacent buildings, and other high-salt-air environments where standard coil coatings degrade prematurely. All units in this family 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 footprint).
- Voltage: 230/208V. Operating range 197V minimum to 253V maximum.
- Amperage with electric heat installed: MCA 19.5A, MOP (breaker) 20A. Total amps 15.5/14.1A (230/208V).
- Power cord/plug: Factory-installed 6-20P (NEMA 6-20) cord with LCDI device per UL 484, since this unit operates under 250V.
- Wall Sleeve is NOT included and must be ordered separately (Amana WS900 series).
- 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 or 265V sub-bases/hard-wire kits. The 265V commercial sibling of this chassis is the Amana PTH074J, which uses a dedicated Amana sub-base (PTSB4**E) or hard-wire kit PTPWHWK4 with disconnect switch PSHW04A — none of that hardware applies to this 230/208V unit.
- Not a drop-in replacement for non-standard or custom sleeve openings outside the 42 in x 16-1/16 in standard.
On seacoast-protected units like this one, the most common callback isn't the compressor — it's condensate backing up into the drywall around the sleeve because the installer leveled it dead flat. Set the wall sleeve with a slight pitch to the outside, roughly 1/4 bubble on a torpedo level, so condensate drains away from the building instead of pooling at the indoor lip. Confirm the plug matches the unit's 6-20P NEMA configuration before rough-in — cross-checking against a NEMA receptacle chart avoids a mismatched 15A/20A receptacle that forces a return trip. On coastal properties, pair this pitch check with periodic inspection of the coil coating per your property management preventive-maintenance schedule, since salt exposure accelerates any point where drainage or sealant fails first.
Key Benefits
- Heat pump operation delivers 6,300/6,100 BTU/h of heating with a COP of 3.6/3.7, reducing reliance on electric resistance heat in moderate outdoor temperatures.
- 3.5/3.0 kW backup electric heat strip engages automatically when outdoor conditions fall below heat pump capacity, delivering up to 12,000 BTU/h (230V) or 9,900 BTU/h (208V) of supplemental heat.
- Dehumidification rate of 1.7 pints/hour helps manage humidity in guest rooms and living spaces during cooling operation.
- Built-in ventilation CFM range of 65-95 supports fresh-air makeup in occupied spaces.
- Feature Code C seacoast corrosion protection extends component life in high-salinity coastal air.
- Refrigerant R-32 is used across this chassis family.

Compatibility & Fitment
- Compatible with 230/208V circuits via factory-installed 6-20P (NEMA 6-20) power cord.
- Fits the industry-standard 42-inch wide by 16-1/16-inch high wall sleeve opening (Amana WS900 series sleeves).
- Not compatible with 115V circuits.
- Not compatible with 265V circuits or 265V-specific sub-bases and hard-wire kits. The 265V commercial sibling, Amana PTH074J, requires an Amana sub-base (PTSB4**E) or hard-wire kit PTPWHWK4 with disconnect PSHW04A — do not attempt to use those components with this 230/208V unit.
- Wall Sleeve is sold separately and NOT included with this unit.
- Exterior Architectural Grille is sold separately and NOT included with this unit.
- Not a drop-in fit for non-standard or custom-depth sleeve openings; extra-deep and custom sleeves are available separately if the standard depth does not match your existing wall opening.

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-inch by 16-1/16-inch wall sleeve opening (Amana WS900 series), but the sleeve, condensate drain kit, and exterior grille must be ordered separately.
What breaker size and plug type does this unit require?
With the 3.5/3.0 kW electric heat strip installed, this unit has an MCA of 19.5A and requires a 20A breaker (MOP). It ships with a factory 6-20P power cord (NEMA 6-20 configuration) and, because it operates under 250V, includes an LCDI power cord per UL 484.
Can this be hardwired for 265V commercial applications?
No. This is a 230/208V unit, not a 265V unit. It is not compatible with 265V circuits and must not be paired with a 265V sub-base or hard-wire kit. The 265V commercial version of this chassis is the Amana PTH074J, which requires an Amana sub-base (PTSB4**E) 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?
[NEEDS VERIFICATION] Installation labor requirements are not specified in the provided manufacturer data. Refer to the warranty PDF in the Resources tab for exact installation and licensing requirements.
Will this fit a standard 42-inch by 16-inch wall sleeve opening?
Yes. This chassis is designed for the industry-standard 42-inch wide by 16-1/16-inch high wall sleeve opening. It is not a drop-in fit for non-standard or custom sleeve openings.
