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 intended for installing the Advanced filtration system with the External PSU Delta model MEA-065A24C on the Original Prusa Enclosure.
⬢Before you start installing the add-on, PRINT OUT ALL NECESSARY PLASTIC PARTS! The External-PSU-bracket-DELTA and the Basic-board-cover are available for download at Printables.com
Note: the External-PSU-bracket-DELTA is intended for mounting the external PSU to the enclosure. However, it is not necessarily required.

⬢Insert the M3nS nut into the External-PSU-bracket-DELTA. Using the Allen key, push the nut all the way into the printed part and align the nut with the hole in the part.
Be careful not to pinch your fingers when handling under the enclosure.
⬢The following instructions are for mounting the external PSU to the enclosure. If you do not want to mount the external PSU to the enclosure, go to Installing the PSU.
⬢Align the holes in the feet bracket with the holes in the bottom profiles.
⬢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.
The following steps are for installing the Advanced filtration system with the External PSU XP Power model VEC65US24.
⬢The following instructions are intended for installing the Advanced filtration system with the External PSU XP Power model VEC65US24 on the Original Prusa Enclosure.

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.
Note: the External-PSU-bracket-XP is intended for mounting the external PSU to the enclosure. However, it is not necessarily required. If you do not want to install the External PSU bracket, go to Removing the LCD.
⬢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.
⬢Slightly lift the bottom panel from the bottom side.
⬢From the bottom side, push the PSU cable with the ferrite bead (cylindrical part) through the hole in the bottom panel into the enclosure.
⬢Guide the PSU cable through the channel in the feet bracket. See the correct orientation of the part.
⬢Maintain the orientation of the feet bracket and attach it to its place on the bottom of the enclosure. Line up the holes in the part with the hole in the bottom frame of the enclosure.
⬢Make sure the cable has not fallen out of the channel.
⬢Secure the feet bracket with two M3x12 screws.
⬢Gently pull the cable back and forth to check for pinching. Keep the excess cable as shown in the picture.
⬢Overhang the rear side of the enclosure over the box or table. It is necessary that both feet on the rear side stand on one anti-vibration pad. Avoid placing the enclosure directly on the frame.

⬢Secure the bottom panel with two M3x4 screws from the bottom.

⬢Secure the feet bracket with two M3x12 screws.
⬢Gently pull the cable back and forth to check for pinching.
⬢Leave the cable extended as shown in the picture. Space between ferrite bead and the feet bracket between 2 - 5 cm.
⬢Overhang the front side of the enclosure over the box or table. It is necessary that both feet on the front side stand on one anti-vibration pad. Avoid placing the enclosure directly on the frame.
⬢Secure the bottom panel with two M3x4 screws from the bottom.
⬢Overhang the left side of the enclosure over the box or table. It is necessary that both feet on the left side stand on one anti-vibration pad. Avoid placing the enclosure directly on the frame.
⬢Secure the bottom panel with four M3x4 screws from the bottom.
⬢Now, place the enclosure on all its feet on the work table and remove the cardboard box. We will not need it anymore.
⬢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.

⬢From the inside, focus on the rear top right corner. The area we will attach the filtration.
⬢Guide the LCD cable through the cutout in the bottom panel.
⬢Secure the textile sleeve on the cable bundle with the zip tie. Do not over tighten the zip tie, it may cut the cables!
⬢From the inside, push two M3x8 screws through the bottom profile.
⬢Place the LCD assembly close to the LCD cables, like in the picture. Mind the same orientation of the LCD as in the picture. See the LCD-supports for better understanding.
Note that both cables are marked with stripes on one side. Correct connection order is important!
⬢Connect the LCD cable marked with TWO STRIPES to the left slot (called EXP2) on the LCD controller.
⬢Connect the LCD cable marked with ONE STRIPE to the right slot (called EXP1) on the LCD controller.
⬢Slide the LCD assembly onto the two M3x8 screws in the frame and tighten them.
⬢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.
