This is a wall-sleeve heat pump for hotel rooms, apartments, or additions where central ductwork isn't available. It's built for property managers and electricians who need self-contained, per-room heating and cooling on a 265V commercial circuit.
The PTH124J35AXXX is an Amana Packaged Terminal Heat Pump (PTHP) rated at 12,000 BTU/h cooling and 11,500 BTU/h heat-pump heating, with a 3.7 kW electric heat strip as backup at 265V. It is suited to hospitality corridors, additions, and multi-family properties where per-room heat pump performance is preferred over strip-heat-only PTAC units. Units in this family meet or exceed 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 (e.g., Amana WS900E / WS900QW sleeve family)
- Voltage: 265V — commercial voltage class, not 115V or 230/208V
- Total Amps (with 3.7 kW heat): 14.2A; MCA 17.9A; MOP 20A with factory-installed cartridge-style time-delay fuses
- Power cord/plug: 7-20P
- Wall Sleeve and Exterior Architectural Grille are sold separately and are NOT included with this unit.
- This 265V unit requires an Amana sub-base (PTSB4**E series) or the PTPWHWK4 hardwire kit with PSHW04A disconnect switch — both sold separately and required for installation.
- Not compatible with 115V circuits
- Not compatible with 230/208V circuits — for that voltage class, see sibling model PTH123J
- Not a drop-in fit for non-standard or custom sleeve openings
Key Benefits
- Heat pump operation (11,500 BTU/h) reduces reliance on electric-resistance heat compared to strip-heat-only PTAC units, with 3.7 kW backup heat for colder days
- EER 11.3 and COP 3.3 for verified compressor efficiency
- Dehumidification rated at 1.7 pints/hr
- Fresh air ventilation adjustable from 65-95 CFM for make-up air in occupied rooms
- R-32 refrigerant
- Meets or exceeds ASHRAE 90.1 commercial efficiency standards

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 (e.g. Amana WS900E / WS900QW), but the sleeve itself and the exterior architectural grille are not included with the PTHP chassis.
What breaker size and plug type does this unit require?
With the 3.7 kW electric heat installed, this configuration has a Minimum Circuit Ampacity (MCA) of 17.9A and requires a Maximum Overcurrent Protection (MOP) of 20A, using cartridge-style time-delay fuses (factory-installed). The unit ships with a 7-20P power cord for 265V service.
Can this be hardwired for 265V commercial applications?
Yes. All 265V Amana PTHP models must be installed with either an Amana sub-base (PTSB4**E series) or the PTPWHWK4 hardwire kit paired with the PSHW04A disconnect switch. Both are sold separately and are not included with this unit.
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 by a licensed electrician per NEC code is standard practice for this voltage class. [NEEDS VERIFICATION - exact warranty installer requirement language is in the manufacturer warranty PDF in the Resources tab]
Will this fit a standard 42-inch by 16-inch wall sleeve opening?
Yes. This chassis is designed for 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.
