This is a wall-sleeve heat pump and backup-heat air conditioner for hotel rooms, apartments, additions, or any room without central ductwork. It's built for property managers and homeowners who need self-contained, per-room heating and cooling with a single 230/208V circuit.
This PTHP is built for hospitality and multi-family retrofit applications where a heat pump with electric-heat backup replaces older PTAC or resistance-heat-only units in the same wall opening. Rated performance figures on this page reflect AHRI-style dual-voltage test data (230V/208V) supplied by the manufacturer. 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 (fits WS900E / WS900QW and compatible sleeve families).
- Voltage: 230/208V. Electric heat strip installed: 3.5 kW at 230V / 3.0 kW at 208V.
- Electrical requirement with heater: MCA 19.5A, MOP 20A, total amps 15.5/14.1 (230V/208V).
- Power cord/plug: Factory-installed 6-20P cord, UL 484 LCDI-equipped (applies to all units under 250V) — requires a matching NEMA 6-20R receptacle.
- Wall Sleeve is NOT included — sold separately. Exterior Architectural Grille is NOT included — sold separately.
- Not compatible with 115V circuits.
- Not compatible with 265V hardwire-only installations. Do not install on a 265V sub-base or hard-wire kit — the 265V commercial equivalent of this chassis is sold as HEH074J and requires its own sub-base/hard-wire kit hardware.
- Not a drop-in fit for non-standard or custom sleeve openings — confirm sleeve model match before ordering.
The most common callback on a PTHP retrofit is water staining below the sleeve, not an electrical fault. Field problem: crews often set the sleeve dead level because it "looks right" against the interior wall line. Long-term fix: pitch the sleeve 1/4 bubble toward the exterior so condensate rolls out through the drain path instead of pooling at the rear and wicking into the sill or drywall over time. Confirm the pitch with a torpedo level held along the sleeve's depth, not just side-to-side — the framing diagram calls for the sleeve to extend at least 1/4 in beyond the outside wall face for this reason. On the electrical side, verify the receptacle is a true NEMA 6-20R before setting the unit; this cord ships as a 6-20P, and forcing it into a 5-20R or a 250V+ 6-30R with an adapter is both a code violation and a fire risk under NEC receptacle-matching rules. Property managers doing multi-unit turns should log sleeve pitch and receptacle type on the same inspection sheet — it catches both failure modes before drywall closes in around them.
Key Benefits
- Heat pump operation delivers 6,300/6,100 BTU/h of compressor-driven heating (230V/208V) before the electric strip is needed, reducing electric-heat runtime in shoulder-season climates.
- EER of 13.3/13.7 (230V/208V) and COP of 3.9/3.9 (230V/208V) reflect efficient compressor performance across both supply voltages.
- 1.7 pints/hr dehumidification helps manage humidity load in guest rooms and multi-family units.
- Built-in fresh-air ventilation (65-95 CFM) supports make-up air needs without a separate ventilation unit.
- Single-stage 3.5/3.0 kW electric heat backup covers cold-snap demand beyond the heat pump's capacity.
- R-32 refrigerant charge, per manufacturer catalog note.

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This chassis fits the industry-standard 42 in wide x 16-1/16 in high sleeve opening (e.g., WS900E / WS900QW families). The Exterior Architectural Grille is also sold 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 19.5 amps and requires a 20-amp maximum overcurrent protection (MOP) device. It ships with a factory-installed 6-20P power cord for a matching NEMA 6-20R receptacle on a 230/208V circuit.
Can this be hardwired for 265V commercial applications?
No. This is a 230/208V unit. It is not rated for 265V circuits and must not be paired with a 265V sub-base or hard-wire kit. The 265V commercial version of this chassis is sold under model HEH074J, which requires an Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect switch PSHW04A (sold separately).
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
Refer to the manufacturer installation manual and warranty document in the Resources tab for the exact installer-qualification requirements. Sealed refrigerant system work should always be performed by a licensed HVAC technician.
Will this fit a standard 42-inch by 16-inch wall sleeve opening?
Yes. This chassis is designed for the industry-standard 42 in x 16-1/16 in wall sleeve opening. It is not a drop-in fit for custom or non-standard sleeve openings without verifying sleeve compatibility first.
