The Advanced filtration system add-on has been shipped with two types of the external PSU, each from a different manufacturer. The functionality of both versions is the same, but the installation procedure is slightly different.
⬢On the label of the external PSU, check what model do you have and follow the appropriate instructions:

⬢The following instructions are for mounting the external PSU to the enclosure, which is optional. If you do not want to mount the external PSU to the enclosure, go to Installing the PSU.
⬢From the inside, push the M3x8 screw through the hole in the bottom profile next to the PRUSA logo.
⬢Attach the external PSU assembly on profile. And align it against the screw.
⬢Tighten the M3x8 screw from inside to mount the external PSU.
⬢Tear open the filter bag and remove the HEPA filter.
Handle the filter with caution. If the HEPA surface (the white pleated surface) is damaged, the filter will lose its efficiency. Protect your hands when you take off the used filter and put it in a plastic bag. A saturated filter is not recyclable.
⬢On the rear side of the enclosure, pull out two nylon rivets on the top left corner.
From the inside, push on the nylon rivets using your thumb or the tip of the needle-nose pliers. When using the pliers, be careful not to damage the back panel and sheet metal profile.
⬢From the inside, focus on the rear top right corner. The area we will attach the filtration.
⬢Check if it works properly. Press the FILTER button on the Basic Board Panel and check if the filter fan is spinning. Keep the enclosure door open, the fan can be easily heard.
⬢Good job! The Advanced filtration system is successfully installed.

Note: the External-PSU-bracket-XP is intended for mounting the external PSU to the enclosure. However, it is not necessarily required.
⬢In the following steps, you will need to access the bottom of the enclosure. You achieve this by having one of the bottom edges of the frame extend beyond the work surface. It is recommended to use a cardboard box and put the enclosure on it.
⬢The size of the box must be at least 600 x 600 x 100 mm.
Hint: you can use the original cardboard box of the Enclosure packaging.
Do not place the enclosure on the box now. Wait for the instruction.

⬢Insert the M3nS nut into the External-PSU-bracket-XP. Using the Allen key, push the nut all the way into the printed part and align the nut with the hole in the part.
⬢Place the enclosure on the cardboard box with the rear side (side with the PSU hole in the back panel) overhanging the box.
⬢It is necessary that both feet on the left side stand on one anti-vibration pad. See the detail. Avoid placing the enclosure directly on the frame.
WARNING: Be extra careful and make sure the enclosure is stable and doesn't wobble. Otherwise, the enclosure may fall off the box and hurt you and damage.
⬢From the bottom, release and remove two screws nearest the right corner.
⬢In the same way, move the enclosure so that the right side overhangs the box.
⬢Release and remove four screws from the bottom profile.
⬢Place the enclosure so that all feet are on the surface.
