Replacing the RF Gasket Assembly

1.If you detect evidence of arcing on the back of the reflector caused by the RF gasket assemblies (behind the reflector), then you will need to replace the two RF gasket assemblies with the main reflector removed.

2.Remove the housing (see “I310M/I311M Irradiator Housing Removal/Replacement” on page 100).

IMPORTANT: The extrusion and the RF gasket assembly are one assembly, and should not be separated from each other. To replace the RF gasket requires removal of the old extrusion as well as the old RF gasket.

3.Access the casting by placing the lamp on its side and gently sliding the casting out of the housing until the eight extrusion screws are accessible. (There are four screws on each side).
