Structural Wall Sleeve Support & Code-Compliant Electrical Concealment

In commercial hospitality, multi-family, and healthcare facilities, local National Electrical Code (NEC) regulations often require PTAC units to be hardwired directly into an enclosed junction box rather than plugged into exposed wall receptacles. The Amana PTCB10K Commercial Subbase provides a heavy-duty, field-accessible electrical enclosure that mounts under the sleeve basepan to meet strict commercial wiring standards.

Engineered for Durability & Fast Jobsite Installation

  • Structural Weight Support: In thin-wall framing or curtain-wall construction, the subbase transfers the weight of the 110+ lb PTAC chassis directly to the floor, eliminating sleeve sagging and wall stress over time.
  • Enclosed Wiring Junction: Houses line-voltage electrical conduit, high-voltage terminal blocks, or optional subbase disconnect switches safely inside a covered metal chassis, protecting wiring from dust, moisture, and guest tampering.
  • Conceals Power Cords & Receptacles: When using standard plug-in units, the subbase fully encloses the LCDI power cord and NEMA wall outlet, presenting a sleek, cord-free room appearance that elevates hotel interior design.
  • Adjustable Leveling Feet: Equipped with heavy-duty threaded leveling legs that allow installers to compensate for uneven subfloors, tile, or carpet tack strips during rough-in.

Heavy-Gauge Galvanized Steel Construction: Built to withstand heavy commercial use and support full chassis weight.

Adjustable Threaded Leveling Feet: Compensates for uneven floors, carpet padding, and masonry thresholds.

Pre-Punched Electrical Knockouts: Allows flexible conduit entry from the floor, back wall, or sides.

Compatible with Subbase Accessories: Accommodates optional fuse kits, power disconnect switches, and duct adapters.

Universal WS900QW Fitment: Pre-punched mounting holes line up perfectly with Amana WS900QW series 42" wall sleeves.

Frequently Asked Questions

Q1: What is the primary purpose of the Amana PTCB10K subbase kit? +

A: The PTCB10K is a floor-mounting steel enclosure that attaches beneath Amana WS900QW wall sleeves. It provides structural weight support for the PTAC unit and serves as an enclosed electrical junction box for hardwired connections or cord concealment.

Q2: Is the Amana PTCB10K required for every PTAC installation? +

A: While not mandatory for all plug-in setups, the PTCB10K is required when local electrical codes mandate hardwired connections, when local building codes require a disconnect switch at the unit, or when additional structural floor support is needed for thin walls.

Q3: Does the Amana PTCB10K subbase raise the height of the wall sleeve? +

A: Yes. The subbase adds 3-1/2 inches of height beneath the WS900QW wall sleeve, which must be factored into rough wall cutout height calculations during framing.

Q4: Can the PTCB10K conceal standard plug-in LCDI power cords? +

A: Yes. If local codes permit plug-in connections inside the subbase enclosure, the NEMA receptacle and power cord can be housed inside the PTCB10K frame to hide cables from room view.

Q5: How does the PTCB10K adjust for uneven floors? +

A: The subbase includes threaded, adjustable leveling feet at the front corners, allowing installers to adjust and level the wall sleeve precisely on uneven subfloors or tile.
