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 electricians who need per-room heating and cooling on a 265V commercial circuit.
The PTH074J35AXXX is an Amana Packaged Terminal Heat Pump (PTHP) built for hospitality and multi-family applications where a 265V commercial circuit is already in place. It combines a heat pump compressor with a 3.7 kW electric heat strip for backup heating below the heat pump's effective range, and it 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.
- Fits the industry-standard 42 in x 16-1/16 in wall sleeve opening.
- Requires a 265V circuit with a 20A maximum overcurrent protection rating (MCA 17.9A) and a 7-20P power cord.
- Wall Sleeve is NOT included — order separately (Amana WS900E, WS900QW, or other WS900 series sleeve).
- Exterior Architectural Grille is NOT included — order separately (SGK, AGK, or PGK series).
- 265V units require an Amana sub-base (PTSB4**E series) or the PTPWHWK4 hard-wire kit with PSHW04A disconnect switch — neither is included.
- Not compatible with 115V circuits.
- Not compatible with 230/208V circuits — for that voltage, see the sibling chassis model PTH073J.
- Not a drop-in fit for non-standard or custom sleeve openings.
On 265V hospitality jobs, techs often assume every sub-base in the truck bin is interchangeable — it isn't, and a mismatched sub-base or missing disconnect is the fastest way to trip an inspection failure. Before setting the sleeve, confirm you have the correct Amana PTSB4**E sub-base or the PTPWHWK4 hard-wire kit with PSHW04A disconnect switch specified for this 265V chassis; do not substitute a 230/208V sub-base. While you're at the sleeve, set your torpedo level across the sleeve's long axis and confirm a 1/4-bubble pitch toward the exterior — this keeps condensate draining outdoors instead of migrating back into the drywall over the unit's service life. Verify the receptacle or hard-wire termination against a NEMA Receptacle Chart before energizing, since a 7-20P cord plugged into an incorrectly wired 265V receptacle is an electrical hazard, not just a nuisance trip. Document the sub-base model number and disconnect switch on the property's PM equipment log — this is standard property management practice for warranty and insurance audits on commercial PTHP installs.

Frequently Asked Questions
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately from the PTH074J35AXXX chassis. This unit fits the industry-standard 42 in x 16-1/16 in wall sleeve opening (e.g., Amana WS900E / WS900QW series), but the sleeve and exterior architectural grille must be purchased separately.
What breaker size and plug type does this unit require?
This configuration (265V with 3.7 kW electric heat) has a Minimum Circuit Ampacity (MCA) of 17.9A and a Maximum Overcurrent Protection (MOP) rating of 20A, using cartridge-style time-delay fuses factory-installed for 265V models. It ships with a 7-20P power cord.
Can this be hardwired for 265V commercial applications?
Yes, but a 265V unit must be paired with an Amana brand sub-base (PTSB4**E series) or the PTPWHWK4 hard-wire kit with PSHW04A disconnect switch. Neither is included with this unit and both are sold separately.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
This is a 265V commercial circuit requiring correct sub-base or hard-wire kit installation. [NEEDS VERIFICATION - exact warranty installer requirement language is in the manufacturer warranty PDF, see Resources tab]
Will this fit a standard 42-inch by 16-inch wall sleeve opening?
Yes. The PTH074J chassis fits 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.
