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 PMH093J35CXXX is a DigiAIR heat pump PTAC built on the Amana PMH093J chassis, rated at 8,700 BTU/h cooling and paired here with a 3.5/3.0 kW electric heat strip for supplemental backup heat below the heat pump's balance point. Feature code C adds seacoast corrosion protection to the cabinet and coil, making this configuration suited for coastal hospitality properties, condos, and residential additions where salt air accelerates standard-coil degradation. Performance is documented in the manufacturer's published EER/COP tables in accordance with AHRI-referenced test conditions. 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 (WS900E / WS900QW family). Rough framing opening is approximately 42-1/4 in wide x 16-1/4 in minimum high.
- Voltage: 230/208V. Operating range 197V minimum to 253V maximum.
- Electric heat: 3.5 kW at 230V / 3.0 kW at 208V, single stage.
- Total amps with electric heat: 15.5A (230V) / 14.1A (208V). MCA: 19.5A. MOP: 20A.
- NEMA plug: 6-20P, factory-installed cord with LCDI device per UL 484 (applies to this sub-250V unit).
- 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 or hardwire-only installs; the 265V commercial sibling is model PMH094J, which requires an Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect PSHW04A, sold separately.
- Not a drop-in fit for non-standard or custom sleeve openings — verify existing sleeve dimensions before ordering this chassis as a replacement.
On seacoast installs, techs often assume the corrosion-protected coil solves all moisture concerns and skip re-checking sleeve pitch — that's the friction point. Any wall sleeve installed dead-level, or worse, pitched inward, lets condensate migrate back toward the drywall and framing over time instead of draining outdoors, which leads to rot and mold behind the unit regardless of coil coating. Set the sleeve with an outward pitch of about 1/4 bubble on a torpedo level before securing it, per the framing guidance for this sleeve family, and confirm the sleeve extends a minimum of 1/4 in beyond the exterior wall face. Before final hookup, also verify the receptacle is a matching NEMA 6-20R for this unit's 6-20P cord — a mismatched 15A receptacle on a unit drawing up to 15.5A total is both a code violation and a fire risk under NEC Article 550 receptacle provisions for room air conditioners. Document the pitch check and receptacle match in your commissioning notes; it's standard practice for property management turnover inspections.
Key Benefits
- Heat pump operation delivers 7,800/7,600 BTU/h of heating without engaging electric heat under moderate outdoor conditions, reducing electric heat runtime and operating cost.
- 3.5/3.0 kW electric heat strip provides backup heat capacity at 12,000 BTU/h (230V) or 9,900 BTU/h (208V) when outdoor temperatures drop below the heat pump's effective range.
- EER of 12.4/12.5 and COP of 3.6/3.6 place this unit's efficiency on record per the manufacturer's published performance data.
- Seacoast corrosion protection (feature code C) targets coastal and high-humidity environments where standard coil coatings degrade faster.
- Fresh air ventilation CFM of 25-35 supports make-up air exchange in sealed hospitality and multifamily units.
- R-32 refrigerant is used in this chassis per manufacturer catalog documentation.

Frequently Asked Questions
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This unit is designed to fit a standard 42 in x 16-1/16 in wall sleeve opening (WS900E/WS900QW family), but you need to order the sleeve, drain kit, and exterior grille as separate line items.
What breaker size and plug type does this unit require?
This configuration (230/208V, 3.5/3.0 kW electric heat) has a Minimum Circuit Ampacity (MCA) of 19.5A and a Maximum Overcurrent Protection (MOP) rating of 20A, so it requires a dedicated 20-amp circuit. It ships with a factory-installed 6-20P power cord and LCDI device per UL 484.
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 sold as model PMH094J, which requires an Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect switch PSHW04A, sold separately. Do not attempt to hardwire this 230/208V model as a substitute.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
Exact installation and warranty-validation requirements are detailed in the manufacturer warranty document. Please refer to the "Resources (System Manuals and Warranty)" Tab above for full terms before installation.
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 (WS900E/WS900QW series). It is not a drop-in fit for non-standard or custom sleeve openings — confirm your existing sleeve dimensions before ordering.
