This is a wall-sleeve heat pump for hotel rooms, apartments, or additions where central ductwork isn't available. It heats and cools from one chassis, with electric heat backup for cold-snap days, and it's built for property managers and homeowners who need self-contained, per-room climate control.
Amana PTH123K35AXXX is an R-410A packaged terminal heat pump (PTHP) built for hospitality rooms, multifamily units, and additions where ductwork isn't practical. This is an R-410A K-series chassis (previous-generation, sell-through stock) and is well suited for like-for-like replacement of existing R-410A PTAC/PTHP installations, since R-410A is being phased down under the EPA AIM Act and matching refrigerant type simplifies service. All units 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.
- Fits the industry-standard 42 in x 16-1/16 in wall sleeve opening.
- Operates on a 230/208V circuit, drawing 19.5A MCA with the 3.5/3.0 kW electric heat installed; requires a 20A breaker (MOP) and NEMA 6-20P/6-20R connection.
- Ships with a factory LCDI power cord (UL 484), standard on all units rated under 250V.
- Wall Sleeve is NOT included - order separately (WS900E, WS900QW, or another sleeve variant matching your project).
- Exterior Architectural Grille is NOT included - order separately (SGK, AGK, or PGK series).
- Not compatible with 115V circuits.
- Not compatible with 265V circuits - do not confuse this with sibling chassis PTH124J, which is the 265V commercial version requiring its own sub-base or hard-wire kit.
- Not a drop-in fit for non-standard or custom-depth sleeve openings; use the extra-deep sleeve series if your wall depth exceeds standard dimensions.
The technical friction on any PTAC/PTHP retrofit is condensate management - if the sleeve sits level or pitches inward, wash-off from the wet coil backs up into the room instead of draining outside. Pitch the sleeve about 1/4 bubble toward the exterior wall (per the framing note in the manufacturer documentation) and confirm it with a torpedo level before you set trim and grille. This prevents water intrusion into the drywall and insulation over the unit's service life, not just at commissioning. Cross-check the sleeve's rough opening against the framing diagram in the manufacturer's install guide, and log the level check on your commissioning sheet - many property management QA programs require photographic proof of level/pitch before final unit sign-off.
Key Benefits
- Heat pump operation delivers 10,600/10,500 BTU/h of heating from the compressor at 230V/208V before the electric heat strip is even called - lower operating cost than heat-strip-only PTAC units in moderate climates.
- 3.5/3.0 kW electric heat backup (12,000 BTU/h at 230V, 9,900 BTU/h at 208V) covers cold-snap capacity when the heat pump alone can't keep up.
- 1.7 pints/hr of dehumidification at rated conditions helps manage humidity in guest rooms and multifamily units without a separate dehumidifier.
- Fresh air vent adjustable from 65-95 CFM for make-up air in occupied spaces.
- EER of 11.0/11.1 and COP of 3.2/3.2 for straightforward efficiency comparison against other PTHP chassis.
- R-410A refrigerant matches most existing PTAC/PTHP stock for straightforward like-for-like replacements.

Compatibility & Fitment
- Compatible with 230/208V circuits via NEMA 6-20P/6-20R power cord and receptacle.
- Fits standard 42 in x 16-1/16 in wall sleeve openings (e.g., WS900E, WS900QW sleeve family).
- Not compatible with 115V circuits.
- Not compatible with 265V circuits - the 265V commercial version of this chassis is PTH124J, which requires its own Amana sub-base (PTSB4**E) or hard-wire kit (PTPWHWK4 with disconnect PSHW04A), sold separately. Do not attempt to run this 230/208V unit, PTH123K35AXXX, on a 265V circuit.

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This chassis fits the industry-standard 42 in x 16-1/16 in sleeve opening (e.g., WS900E/WS900QW family), but you need to order a sleeve and, if the exterior finish matters, an outdoor grille (SGK, AGK, or PGK) separately.
What breaker size and plug type does this unit require?
With the 3.5/3.0 kW electric heat installed, this unit has an MCA of 19.5A and a maximum overcurrent protection (MOP) rating of 20A, and it ships with a factory NEMA 6-20P power cord. Confirm your receptacle is a matching NEMA 6-20R on a dedicated 20A, 230/208V circuit.
Can this be hardwired for 265V commercial applications?
No. This model, PTH123K35AXXX, is a 230/208V unit and is not compatible with 265V circuits. The 265V commercial sibling chassis is PTH124J, which requires an Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect switch PSHW04A (sold separately), plus factory-installed cartridge-style time-delay fuses. Do not attempt to wire this unit for 265V service.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
[NEEDS VERIFICATION] - installer licensing requirements are not specified in the provided source data. Refer to the warranty PDF in the Resources tab for exact installation and registration 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 sleeve opening. It is not a drop-in fit for non-standard or custom-depth sleeve openings; those require the extra-deep sleeve variants sold separately.
