Use this procedure only to replace FP‐200 gun modules. To rebuild the
modules, follow the instructions provided with the module rebuilding kits
(refer to Section8, Parts).

procedure in Section3, Installation).
2. Move the applicator circuit breaker to the OFF position, then disconnect
and lock out input electrical power to the applicator (seeFigures7‐1 and
