This is a wall-sleeve heat pump and backup-heat system for hotel rooms, apartments, or additions where central ductwork isn't available. It's built for property managers and homeowners who need self-contained, per-room heating and cooling in one chassis.
The PMH073J35AXXX is a DigiAIR heat pump PTAC built for hospitality rooms, additions, and multi-family units where ducted HVAC isn't practical. Performance is rated at 230V and 208V per the manufacturer's dual-voltage catalog, and the unit meets or exceeds 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, e.g. Amana WS900E / WS900QW sleeves).
- Voltage: 230/208V. Voltage window per manufacturer note: min 197V / max 253V.
- Electric heat strip: 3.5 kW at 230V / 3.0 kW at 208V, single stage.
- Total amps with heater: 15.5A (230V) / 14.1A (208V). MCA: 19.5A. MOP: 20A.
- NEMA plug/power cord: 6-20P, factory-installed, ships with LCDI device per UL 484 (applies to units under 250V).
- 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 — do not attempt to hardwire this 230/208V unit using a 265V sub-base or hard-wire kit. The 265V commercial version of this chassis is the Amana PMH074J, which requires its own Amana sub-base (PTSB4**E series) or hard-wire kit (PTPWHWK4) with disconnect switch (PSHW04A).
- Not a drop-in fit for non-standard or custom sleeve openings outside 42 in x 16-1/16 in.
Matching the NEMA 6-20P cord to the correct 6-20R wall receptacle sounds simple, but it's the number one field error on 230/208V PTHP swap-outs — crews grab a 5-20 receptacle left over from a straight 115V job and the plug won't seat. Before you set the sleeve, verify the existing receptacle against a NEMA Receptacle Chart and confirm it's rated for 230/208V at 20A, not 115V. A mismatched receptacle forces an unauthorized cord swap in the field, which voids the factory LCDI protection required under UL 484. On the sleeve itself, use a Torpedo Level to confirm the unit pitches roughly 1/4 bubble toward the exterior wall — this keeps condensate draining outward instead of pooling against interior drywall. Document both checks on the property's install ticket; it's standard practice for satisfying NEC receptacle compliance and for property management liability records on multi-unit hospitality jobs.
Key Benefits
- Heat pump operation supplies 6,200/6,100 BTU/h of heating (230V/208V) without engaging electric heat in moderate outdoor conditions, reducing electric heat runtime.
- 3.5/3.0 kW electric heat strip provides 12,000/9,900 BTU/h of backup heat for cold-weather performance below the heat pump's effective range.
- EER of 12.6/12.7 and COP of 3.6/3.6 (230V/208V) reflect certified cooling and heating efficiency for this chassis.
- Built-in fresh air ventilation (25-35 CFM) supports make-up air needs in hospitality applications.
- R-32 refrigerant per manufacturer catalog note.
- Meets or exceeds ASHRAE 90.1 efficiency standards.

Compatibility & Fitment
- Compatible with 230/208V circuits via the factory-installed NEMA 6-20P plug, into a matching 6-20R receptacle.
- Fits the industry-standard 42 in x 16-1/16 in wall sleeve opening (e.g., Amana WS900E, WS900QW sleeves).
- Not compatible with 115V circuits.
- Not compatible with 265V circuits or 265V-only sub-bases/hard-wire kits. For 265V commercial applications, the correct chassis is the Amana PMH074J, which requires an Amana sub-base (PTSB4**E series) or a hard-wire kit (PTPWHWK4) with disconnect switch (PSHW04A) — none of these are used with this 230/208V unit.
- Wall Sleeve NOT included — must be purchased separately.

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 in wide x 16-1/16 in high sleeve opening, but you need to order a sleeve (such as the WS900E or WS900QW) and an exterior grille 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 NEMA 6-20R receptacle.
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 the Amana PMH074J, which requires an Amana sub-base (PTSB4**E series) or a hard-wire kit (PTPWHWK4) with a disconnect switch (PSHW04A), none of which are included or applicable to this 230/208V model.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
[NEEDS VERIFICATION] — installation labor requirements for warranty validity are not specified in the provided manufacturer data. Refer to the warranty PDF in the Resources tab for exact terms.
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 non-standard or custom sleeve openings.
