This is a wall-sleeve air conditioner and electric-heat unit for hotel rooms, apartments, or seacoast-adjacent properties where central ductwork isn't available and corrosion resistance matters. It's built for property managers and homeowners near coastal environments who need self-contained, per-room climate control that resists salt-air corrosion.
This PTAC with electric heat is built for hospitality and multi-family properties in coastal or salt-air environments, where standard chassis coatings corrode prematurely. The unit carries the feature-code "C" seacoast corrosion-protection treatment on its chassis components, and the cooling/heating performance 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: Industry-standard 42 in wide x 16-1/16 in high (rough framing opening approx. 42-1/4 in x 16-1/4 in minimum).
- 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 heater amps: 15.5/14.1A. MCA: 19.5A. MOP (breaker size): 20A.
- Power cord/plug: NEMA 6-20P, factory-installed, with LCDI device per UL 484 (applies to units under 250V).
- Wall Sleeve is NOT included — sold separately.
- Exterior Architectural Grille is NOT included — sold separately.
- Not compatible with 115V circuits.
- Not for 265V hardwire-only commercial installs. The 265V commercial sibling of this chassis is the HEC074J — it requires an Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect switch PSHW04A (both sold separately) and does not ship with the same 6-20P cord/LCDI configuration.
- Not a drop-in fit for non-standard sleeve openings outside the 42 in x 16-1/16 in industry standard.
The most common callback on coastal PTAC installs isn't the compressor — it's water intrusion at the sleeve. Wall sleeves must pitch slightly toward the exterior so condensate drains outside rather than tracking back into the wall cavity and drywall. Set the sleeve level side-to-side, then introduce a 1/4-bubble pitch toward the outside wall using a torpedo level before securing it in the rough opening (per the framing guidance for this chassis). Skipping this step is the leading cause of hidden drywall rot behind PTAC sleeves in hospitality properties. Also confirm the receptacle is a matching NEMA 6-20R before energizing — mismatched receptacles on a 20A/6-20P heater cord are a NEC Article 210 violation and a fire risk, not just an inconvenience. Property managers should log sleeve pitch and receptacle verification on the same commissioning checklist used for unit swaps.

Compatibility & Fitment
- Compatible with 230/208V circuits via factory-installed NEMA 6-20P plug.
- Fits standard 42-inch x 16-1/16-inch wall sleeve openings, including WS900E, WS900QW, and seacoast-rated WS900SC sleeve models.
- Not compatible with 115V circuits.
- Not suitable for hardwire-only 265V applications — that configuration is the separate HEC074J chassis, which requires the Amana PTSB4**E sub-base or PTPWHWK4/PSHW04A hard-wire kit.
- Wall Sleeve NOT included — order separately.
- Exterior Architectural Grille NOT included — order separately.
- Not a drop-in replacement for non-standard or custom sleeve openings.

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This unit fits the industry-standard 42-inch by 16-1/16-inch sleeve opening (compatible sleeves include WS900E, WS900QW, and the seacoast-rated WS900SC), but you must order a sleeve and exterior grille separately.
What breaker size and plug type does this unit require?
This configuration ships with a 6-20P power cord and requires a 20-amp breaker (MOP). MCA is 19.5 amps. These figures come from the electric heat performance table for the 3.5/3.0 kW heater, not the chassis-only compressor rating.
Can this be hardwired for 265V commercial applications?
No. This unit is rated 230/208V and ships with a factory power cord. It is not a 265V model. The 265V commercial sibling of this chassis is the HEC074J, which requires an Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect switch PSHW04A, sold separately, along with factory-installed cartridge-style time-delay fuses.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
[NEEDS VERIFICATION] Exact installer-licensing requirements for warranty validity are not confirmed in the provided specification data. Refer to the warranty document in the Resources tab for exact terms.
Will this fit a standard 42-inch by 16-inch wall sleeve opening?
Yes. This chassis fits 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 outside these dimensions.
