If you received a new heatbed assembly with your upgrade kit, skip these steps.
This part may vary slightly in the design of the cover, location of the screws and number of the screws.
Remove the screws fixing the cable bundle.
Remove the screw securing the cover. From the underside, grasp the middle M3nN nut with the pliers while loosing the screw.
Remove the cover.
Release the screws fixing the heatbed power cables and remove the cables from the heatbed. From the underside, grasp the M3nN nuts with the pliers while loosing the screws.

From the bottom side of the heatbed, peel off the yellow Kapton tape and silver aluminum tape.
Remove the heatbed thermistor cable from the heatbed.

Step 4 New heatbed thermistor: parts preparation

For the following steps, please prepare:
MK4 Heatbed thermistor (1x)
Kapton tape (1x)
Aluminum tape (1x)
Pay attention to the instructions! The "yellow" Kapton tape tends to curl up and you won't be able to restore its initial shape!!
All the necessary parts can be found in the Heatbed thermistor set bag.

Step 5 Preparing the heatbed and thermistor

After you have removed the thermistor and the tapes, clean the entire board to remove any grease. You can leave the glue, which was under the aluminum tape.
Place the thermistor on the heatbed. The tip of the thermistor must be in the circle.
If you miss this spot, the printer will read incorrect temperature values.
Take the silver aluminium tape and carefully peel off the protective film.
Glue the tape to the heatbed, BUT ONLY in the centre of the thermistor (inside the circle shape). We need to double-check the correct position.
Peel or bend the tape slightly, to reveal the tip of the thermistor.

Step 6 Covering the thermistor

Maintain the thermistor position and cover it with aluminum tape. Ensure that the whole thermistor sensor is covered with the tape.

Step 7 Fixing the thermistor in place

Now it is time to apply the final "yellow" Kapton tape. DON'T PEEL OFF the entire tape, it will curl up!!!
Peel off about 1 cm (0.5 inches) strip of the Kapton tape and stick it to the heatbed, like in the picture. Ensure the tape is properly connected.
Make sure the Kapton tape does not overlap any screw holes in the heatbed.
The Kapton tape has a bigger area than the silver tape. Make sure the silver tape is overlapped from all sides.
Continue with gluing the tape and stop for a second above the area with the thermistor. Pay great attention to sticking the tape everywhere.
Finish gluing the tape to the heatbed. Double-check the entire surface is properly connected.

Step 9 Inserting the M3nEs nuts

Insert the M3nEs nut into the left short extrusion (side without the PSU). Insert the side with the spring (metal plate) first.
Push the entire nut inside the extrusion using your finger.
Use this method for both M3nEs nuts. The exact position of the nuts doesn't matter at this time.

Step 11 Installing the cable clips

Turn the frame like in the picture and focus on the marked area
Take one of the cable clips and hook the side with the clip into the inner groove of the lower longer extrusion. There is a hook on the part, see the detail.
Place the other end of the clip on the underside of the extrusion.
Use more force to push on the bottom side of the cable clip. It must fit into the groove and you must feel it "click" in.

Step 12 Installing the cable clips

Place the spacer into the circular recess in the PG-front-case and push it all the way down. Note the correct orientation of the washer.
The side of the washer with the three circles must not face up! Otherwise, the planetary gear won't work properly.
Make sure the washer is pushed evenly into the printed part.

This and the following step are optional. Also, please BE PATIENT, smaller letters require more effort in order to be transfered and glued properly.
Using the cleaning pad, clean the side without the circle hole on the xLCD-cover.
Peel off a piece of the protective layer and carefully glue the sticker on the xLCD-cover. Maintain the sticker aligned with the edges of the display cover. Start on the bottom side.
Notice the white PRUSA lettering through the sticker. Compare the orientation with the second picture.
After gluing the sticker, run your finger along the entire length of the sticker in all directions to ensure perfect adhesion.

This process requires patience and care. Perfect adhesion depends on proper degreasing of the part and the ambient temperature.
Start slowly peeling off the application layer. Lightly press the layer onto the lettering as you peel it off. Observe whether all the letters are glued on.
After peeling off the application layer, check that the final look matches the picture.
