This is a wall-sleeve air conditioner and electric heater for hotel rooms, apartments, assisted-living units, or additions where central ductwork isn't available. It's built for property managers and homeowners who need self-contained, per-room climate control on a standard 230/208V circuit.
The PTC173K35AXXX is an R-410A PTAC unit from the Amana K-series (previous generation, sell-through stock), suited to hospitality rooms, additions, and multi-family units where a self-contained, per-room system replaces central ductwork. R-410A remains a sound choice for like-for-like replacement of existing R-410A installations, though it is being phased down under the EPA AIM Act; this model 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 PTAC opening)
- Voltage: 230/208V
- Total amps with electric heat: 15.5/14.1A; MCA 19.5A; MOP 20A
- Power cord / plug: 6-20P, factory-installed LCDI cord per UL 484 (applies because this unit operates under 250V)
- Wall Sleeve is NOT included — order separately (e.g., WS900E, WS900QW, or another compatible Amana sleeve).
- Exterior Architectural Grille is NOT included — order separately (SGK, AGK, or PGK series).
- Not compatible with 115V circuits.
- Not for 265V hardwire or sub-base installations — this is a 230/208V unit, not a 265V unit.
- Not a drop-in fit for non-standard or custom sleeve openings outside 42 in x 16-1/16 in.
Getting the sleeve pitch wrong is one of the most common callbacks on PTAC installs. The friction point: installers sometimes set the sleeve dead level because it "looks right," but that traps condensate inside the chassis instead of routing it outdoors. Over months, that trapped moisture wicks into the surrounding drywall and framing, leading to hidden rot and mold complaints long after the install crew is gone. Pitch the sleeve 1/4 bubble toward the outside wall — check it with a torpedo level before you close up the rough opening, not after. This matches Amana's own framing guidance (rough opening approx. 42-1/4 in wide x 16-1/4 in minimum high, sleeve extending a minimum of 1/4 in beyond the outside wall face). For hospitality properties running multiple units on one exterior wall, verifying pitch unit-by-unit during rough-in, rather than trusting a single template, is standard property management practice and saves a maintenance callback per room down the line.

Compatibility & Fitment
- Fits the industry-standard 42 in wide x 16-1/16 in high PTAC wall sleeve opening.
- Compatible with 230/208V circuits via the factory-installed 6-20P power cord.
- Not compatible with 115V circuits.
- Not for 265V hardwire or sub-base configurations — this chassis is a 230/208V unit, not a 265V unit, and does not use a PTSB4**E sub-base or PTPWHWK4 hardwire kit.

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This unit fits a standard 42 in x 16-1/16 in sleeve opening, but you need to order a compatible Amana sleeve (such as WS900E or WS900QW) and exterior grille on their own.
What breaker size and plug type does this unit require?
This configuration ships with a 6-20P power cord and requires a minimum circuit ampacity (MCA) of 19.5A with a maximum overcurrent protection (MOP) of 20A, based on the 3.5/3.0 kW electric heat strip installed.
Can this be hardwired for 265V commercial applications?
No. This unit is a 230/208V model and is not compatible with 265V circuits. It ships with a factory-installed LCDI power cord (UL 484) appropriate for voltages under 250V, not a 265V hardwire or sub-base configuration.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
The unit is designed for plug-and-play use into a properly rated 230/208V receptacle matching the 6-20P cord. Sleeve installation, framing, and any electrical work outside factory-supplied cord and plug should follow local code and property management standards; refer to the warranty PDF in the Resources tab for full terms.
Will this fit a standard 42-inch by 16-inch wall sleeve opening?
Yes. This chassis is built for the industry-standard 42 in wide x 16-1/16 in high sleeve opening. It is not a drop-in fit for non-standard or custom sleeve openings.
