Installing Your Amana Through-the-Wall AC: Step-by-Step Prep Guide

🛠️ Why Proper Installation Matters

A correct installation of your Amana 11,900 BTU Through-the-Wall AC with Electric Heat (PBE123J35AA) ensures:

• Efficient cooling and heating performance

• Reduced energy bills

• Extended unit lifespan

• Safe electrical operation

Poor installation can lead to water leaks, electrical hazards, and decreased efficiency. This guide, built for Mike Sanders and practical homeowners, will walk you through every prep and installation step.

📏 Measure Twice: Wall Cutout and Sleeve Requirements

Before purchasing, confirm your wall can accommodate:

• Wall sleeve dimensions: Ensure compatibility with Amana’s recommended sleeve.

• Wall thickness: Measure the thickness (typically 5" to 8") to confirm sleeve fit.

• Clearance: Ensure at least 6" clearance on all sides for airflow.

• Proper slope: Wall sleeve should slope ¼" downward outdoors for drainage.

Check the Amana PBE123J35AA manual for exact cutout and sleeve dimensions.

🪚 Cutting the Wall Opening

If replacing an old unit, measure the existing opening. If cutting new:

✅ Mark the wall cutout with painter’s tape.

✅ Use a stud finder to avoid structural studs.

✅ Cut through drywall with a reciprocating saw.

✅ Remove insulation and cut through exterior sheathing.

✅ Frame the opening with treated 2x4s for sleeve support.

✅ Install flashing and waterproof membrane around the opening.

Tip: Consult your local codes to ensure your cutout complies with building requirements.

⚡ Electrical Requirements: 230/208V Setup

This unit requires 230/208V power, typically requiring:

• A dedicated 20-amp double-pole breaker.

• A compatible receptacle or direct wiring.

• Verification of voltage with a multimeter.

Consult a licensed electrician if you are unfamiliar with high-voltage wiring to ensure NEC code compliance. The Electrical Safety Foundation International offers guidelines for homeowner electrical safety.

🧰 Installing the Wall Sleeve

1️⃣ Insert the wall sleeve into the framed opening. 2️⃣ Level the sleeve, ensuring a slight outward tilt. 3️⃣ Secure the sleeve to framing using corrosion-resistant screws. 4️⃣ Apply exterior-grade caulk around the sleeve for weatherproofing. 5️⃣ Install the rear grille if your model requires it.

The sleeve acts as a structural cradle, weather barrier, and vibration dampener for your Amana unit.

🌬️ Installing the Amana Unit into the Sleeve

1️⃣ Remove the front grille and filter. 2️⃣ Slide the AC unit carefully into the sleeve until it clicks into place. 3️⃣ Secure with provided mounting brackets or screws. 4️⃣ Reinstall the filter and front grille. 5️⃣ Plug in or connect to the dedicated circuit. 6️⃣ Test the unit on cooling and heating modes.

Pro Tip: A helper will ease the process when sliding the unit into the sleeve.

💧 Ensuring Proper Drainage

Your Amana AC uses a condensate management system:

• Confirm the outward slope.

• Check drain holes at the rear of the unit.

• Keep weep holes clear of debris.

• Install an optional drain kit if needed in high-humidity environments.

The U.S. Department of Energy recommends checking drainage seasonally to avoid moisture issues inside your wall.

🔧 Testing and Final Checks

✅ Test the remote and onboard controls.

✅ Check heating mode for proper function.

✅ Ensure there is no vibration or rattle.

✅ Inspect weatherproofing from the exterior.

✅ Confirm cool air exhaust outdoors and smooth airflow indoors.

🛡️ Maintenance Tips Post-Installation

After installation:

• Clean filters monthly.

• Check and clean coils seasonally.

• Inspect caulking annually.

• Use surge protection to protect electronic components.

Following the Energy Star maintenance recommendations ensures your Amana AC runs efficiently for years.
