Weatherproof the PTAC Unit

Proper weatherproofing helps prevent energy loss and protects the unit from harsh outdoor conditions. Ensuring a good seal will keep your PTAC running efficiently.

• Use weatherproof foam or caulk around the edges of the unit.

• Install weather stripping along the wall sleeve to prevent drafts.

• Ensure the unit is positioned so water drains away from the building.

Install the Wall Sleeve

The wall sleeve holds the PTAC unit in place and ensures proper ventilation. Make sure the sleeve is level and properly aligned before inserting the unit.

• Slide the wall sleeve into the opening, ensuring it fits snugly and aligns with the wall.

• Check that the sleeve is level to prevent any drainage issues.

• Apply weather-resistant tape around the edges of the sleeve.

• Double-check for any cracks or openings that could allow air or moisture inside.

Prepare the Electrical Connections

Proper electrical connections are essential for safely powering the unit. Follow the PTAC’s manual to ensure you are meeting all electrical requirements.

• Verify that the outlet is compatible with the unit’s power needs.

• If necessary, install a dedicated circuit to handle the electrical load.

Once the wall sleeve is installed, carefully place the PTAC unit inside. Proper placement ensures it will be secure and aligned with the opening.

• Gently slide the unit into the sleeve, making sure it fits without forcing it.

• Align the unit’s sides with the wall to ensure even installation.

• Ensure the unit’s back is flush with the wall for proper insulation and drainage.
