7.1.2 Installation Gasket Replacement
The installation gasket protects the FP and improves its water resistance. For instructions on installing the FP
unit's gasket, refer to the following page.

Installation Gasket Replacement Procedure
(1) Place the FP on a flat, level surface with the display
facing downwards.
(2) Remove the old gasket from the FP.
(3) Attach the new gasket to the FP. Be sure to insert the
gasket into the FP unit’s groove so that the gasket’s
groove sides are vertical.
(4) Check if the gasket is attached to the FP correctly.
The upper surface of the gasket should protrude
approximately 2mm out from the groove.

3 Installation and Wiring (page3-1)
• A gasket which has been used for a long period of time may have scratches or
dirt on it, and could have lost much of its water resistance. Be sure to change the
gasket at least once a year, or when scratches or dirt become visible.
• The gasket must be inserted correctly into the groove for the FP unit’s moisture
resistance to be equivalent to IP65f.
• Be sure the gasket's seam is not inserted into any of the unit's corners, only in the
straight sections of the groove. Inserting it into a corner may lead to its eventually
tearing.
• Install the gasket as it comes to the under side of the display area. Otherwise it
could not sufficiently prevent from dust and water.
• The upper surface of the gasket should protrude approximately 2mm out from the
groove. Be sure to check that the gasket is correctly inserted before installing the
FP into a panel.
