This is a wall-sleeve heat pump 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 protection against coastal corrosion.
Amana's PTH094J35CXXX is a Packaged Terminal Heat Pump (PTHP) engineered for hospitality and multi-family properties in coastal or high-corrosion environments, using a compressor-driven heat pump with 3.7 kW electric heat backup for cold-weather operation. This model carries Amana's Seacoast Protection feature (Feature Code C), which adds corrosion-resistant coil and cabinet treatment for buildings near saltwater. Cooling and heating performance figures are rated in line with Amana's published catalog data. 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 (WS900E / WS900QW series depth 14 in).
- Voltage: 265V, operating range 239–292V. This is a 265V commercial unit — not compatible with 115V circuits and not compatible with 230/208V circuits. The 230/208V version of this chassis is sold as model PTH093J.
- Electric heat: 3.7 kW, single stage. Total amps 14.2A, MCA 17.9A, MOP 20A.
- Power cord/plug: 7-20P NEMA configuration.
- The Wall Sleeve is NOT included. It must be ordered separately (see wall sleeve models below).
- The Exterior Architectural Grille is NOT included. It must be ordered separately (SGK, AGK, or PGK series).
- This 265V unit requires an Amana brand sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect switch PSHW04A — neither is included.
- Not suitable for hardwire-only installation without the required sub-base or hardwire/disconnect kit listed above.
- Not a drop-in replacement for non-standard or custom sleeve openings.
The technical friction on 265V seacoast units is twofold: matching the correct sub-base to a commercial disconnect, and getting condensate drainage right in salt-air environments where sleeve corrosion accelerates any standing water problem. Skipping the pitch check is the most common long-term failure point — improperly leveled sleeves let condensate back up into the wall cavity instead of draining outdoor, leading to drywall rot and mold behind the unit. Field-verify sleeve pitch with a torpedo level: the sleeve should read level side-to-side but pitched approximately 1/4 bubble toward the exterior wall face. On the electrical side, confirm the sub-base (PTSB4**E) or hardwire kit (PTPWHWK4/PSHW04A) matches the unit's 7-20P/265V configuration against a NEMA receptacle chart before energizing — do not assume factory labeling matches field wiring on retrofit jobs. This aligns with NEC receptacle code requirements for dedicated commercial circuits and is standard practice for property managers doing multi-unit PTAC/PTHP turnovers.
Key Benefits
- Heat pump operation delivers 8,200 BTU/h of compressor-driven heating, supplemented by 3.7 kW electric heat (12,600 BTU/h) for colder conditions.
- EER of 12.4 and COP of 3.5 support efficient year-round cooling and heating performance.
- Dehumidification rate of 2 pints/hr helps manage humidity in guest rooms and living spaces.
- Vent CFM range of 65-95 provides adjustable fresh-air intake (make-up air) for occupied spaces.
- Seacoast Protection (Feature Code C) adds corrosion resistance for coastal and high-salinity installations.
- Fits the industry-standard 42 in x 16-1/16 in wall sleeve opening used across most PTAC/PTHP replacement projects.

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 wall sleeve opening, but you will need to order a compatible sleeve (such as the WS900E, WS900QW, or a seacoast-rated sleeve) and the exterior architectural grille separately.
What breaker size and plug type does this unit require?
With the 3.7 kW electric heat installed, this unit requires a Minimum Circuit Ampacity (MCA) of 17.9A and Maximum Overcurrent Protection (MOP) of 20A, using a 7-20P plug configuration at 265V. Units without electric heat use 15A overcurrent protection.
Can this be hardwired for 265V commercial applications?
Yes. This 265V unit must be installed with an Amana brand sub-base (PTSB4**E series) or the hard-wire kit PTPWHWK4 paired with disconnect switch PSHW04A. Neither the sub-base nor the hard-wire kit is included with this unit. Factory-installed cartridge-style time-delay fuses are required for 265V operation.
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 switch. Installation should follow NEC electrical code and local property management standards. Refer to the "Resources (System Manuals and Warranty)" Tab above for the manufacturer's exact installation and warranty requirements.
Will this fit a standard 42-inch by 16-inch wall sleeve opening?
Yes. This chassis fits 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 sleeve openings.
