Installation: Durastar Foldable PTAC Wall Sleeve DRPTACWS Instruction Manual

Content

Overview

The Foldable PTAC Wall Sleeve DRPTACWS is a foldable wall sleeve designed to support a PTAC unit during through-the-wall installation. It is intended for users who need a standard-size sleeve that can be assembled on site, then paired with a compatible PTAC unit and optional drain kit for proper condensate management.

Foldable PTAC Wall Sleeve DRPTACWS is built around separate top, bottom, left, and right cover panels that form the sleeve body after assembly. The included sealing strips help complete the fit and support a cleaner installation around the unit.

Detailed description

The Foldable PTAC Wall Sleeve DRPTACWS is assembled from four main shell pieces: the bottom cover, top cover, left cover, and right cover. Once the sleeve body is formed, Seal A and Seal B are placed at specific locations on the top and bottom rear edges to help complete the sleeve assembly.

The sleeve is designed to accept a PTAC unit that is slid in while kept level. After the unit is fully seated against the front of the sleeve, it is secured through the flange holes with long screws. This makes the sleeve a structural support component as well as an installation interface for the unit.

The optional drain kit adds a controlled condensate outlet. It can be configured for back-side drainage or bottom-side drainage, depending on the site layout and the preferred drainage path.

Safety

Use care when lifting and moving the PTAC unit so it stays level during installation. A level lift helps the unit slide correctly into the wall sleeve and reduces the chance of misalignment.

Before tightening drain kit fasteners, confirm that the tube position will still allow the sleeve to pass through the wall. When installing the bottom drain, tighten the screws gently and evenly to avoid damaging the tube. Fasten the rear cover plates securely to help prevent leaks.

Setup and operation

Sleeve assembly

Open the left cover and right cover.
Install six short screws as shown in the assembly layout.
Attach the bottom cover to the left and right covers using eight short screws.
Turn the sleeve over.
Attach Seal A and both Seal B pieces in the marked locations on the sleeve.

Unit installation

Lift the PTAC unit while keeping it level.
Slide the unit into the wall sleeve until it sits firmly against the front of the sleeve.
Secure the unit with four long screws through the unit flange holes.

Drain kit assembly for back-side drainage

Attach a foam gasket to the drain outlet plate and cover plate.
Insert the bent tube into the drain outlet plate and rotate it into the correct position.
Install the tube and drain outlet plate on the rear outlet of the sleeve using two screws.
Install the cover plate on the other outlet using two screws.
Place the drain tube on either side of the sleeve if needed, but make sure the final position still allows the sleeve to fit through the wall.

Drain kit assembly for bottom-side drainage

Attach a foam gasket to the drain outlet plate and cover plates.
Insert the straight tube into the drain outlet plate.
Drill two 1/8 in holes in the bottom of the sleeve aligned with the drain outlet plate holes.
Drill one 3/8 in to 1/2 in hole between the two smaller holes.
Attach the tube and drain outlet plate to the bottom of the sleeve using two screws.
Install the two cover plates over the rear outlets using four screws and tighten securely to reduce leak risk.

Troubleshooting

If the sleeve does not fit through the wall after drain kit assembly, recheck the bent tube position before tightening the rear fasteners.
If the drain connection feels stressed during installation, loosen the screws and realign the tube to avoid tube damage.
If you want to reduce leak risk, make sure the cover plates are firmly fastened and the foam gaskets are seated properly.
If the PTAC unit does not seat correctly, confirm that it was inserted level and pushed fully against the front of the sleeve.

Faqs

How do you assemble the Foldable PTAC Wall Sleeve DRPTACWS before installing the unit?

Start by opening the left and right covers, then install the short screws in the first set of connection points. Next, attach the bottom cover to the left and right covers using the remaining short screws, making sure the frame is square and fully seated. After that, turn the sleeve over and attach the seals in the specified locations. A careful assembly helps the PTAC wall sleeve stay aligned and makes unit installation much easier.

What seals are included with the DRPTACWS wall sleeve, and where do they go?

The DRPTACWS uses one long seal and two short seals to help close off gaps around the sleeve. Seal A is placed along the rear top section, while Seal B is installed at the rear bottom areas on both sides. These seals are important because they help improve fit and reduce air leakage around the foldable wall sleeve. Make sure each seal is positioned where the diagram shows before sliding the PTAC unit into place.

How is the PTAC unit secured inside the foldable wall sleeve?

Once the wall sleeve is assembled and installed, lift the PTAC unit while keeping it level and slide it into the sleeve until it sits firmly against the front of the sleeve. The unit is then secured through the flange holes using four long screws. Keeping the unit level during insertion helps prevent binding, protects the sleeve edges, and makes it easier to achieve a solid, stable installation.

Can the DRPTACWS drain kit be set up for both rear drainage and bottom drainage?

Yes, the drain kit supports both back-side drainage and bottom-side drainage. For rear drainage, the bent tube is used and attached to the back outlet. For bottom drainage, the straight tube is used and the sleeve requires drilled holes in the bottom to match the drain outlet plate. In both setups, foam gaskets and cover plates help seal unused outlets and reduce the chance of leaks.

What should I check before tightening the rear drain kit on the DRPTACWS sleeve?

Before fully tightening the rear drain screws, confirm that the bent tube is rotated into a position that still allows the sleeve to pass through the wall opening. The drain tube can be placed on either side of the sleeve, which gives some flexibility during installation. This step matters because an incorrectly positioned tube can interfere with wall fit, create stress on the parts, or make final installation more difficult.

How do I install the bottom drain kit on the foldable PTAC wall sleeve?

For bottom drainage, attach the straight tube to the drain outlet plate, then mark and drill two small alignment holes in the bottom of the wall sleeve plus one larger center hole. After that, fasten the tube and drain outlet plate to the sleeve with screws. Tighten the screws gently and evenly so the tube is not damaged. Finish by installing the cover plates over the unused outlets on the back of the sleeve.

What are the most important installation precautions for the DRPTACWS?

The most important precautions are to keep the PTAC unit level, match the sleeve parts correctly, and avoid overtightening screws on the drain kit. The drain components should be positioned before final tightening so they do not interfere with wall fit. When installing the unit, slide it in until it is firmly against the front of the sleeve. Careful alignment helps prevent leaks, damage to the sleeve, and mounting problems later.

What common troubleshooting step should I try if the sleeve or drain kit does not fit correctly?

If the sleeve or drain kit does not fit as expected, recheck the assembly order, screw placement, and tube orientation before forcing anything into position. Make sure the seals are installed in the correct spots and that the drain tube leaves enough clearance for wall insertion. For bottom drainage, verify that the drilled holes line up with the drain plate. Small alignment errors are the most common cause of fit issues.
