Prerequisite Step

The faceplate needs to be removed (see right) prior to any of the following steps taking place. Detach the screen cables (see below)

Step 1

• Remove cap from sealant and install into generic 310ml applicable cartridge applicator gun.

Step 2

• Using existing double sided adhesive tape. Ensure screen is positioned correctly and installed.
• If you have already used the installed double-sided tape. Ensure the screen is placed on a soft surface – to free screen from damage – whilst under sealant applicator operation.

Step 3

• Using the sealant – apply a bead [see illustration] to the underside of the screen.
•  This will create full peripheral coverage.
