Figure 34. Gasket Installation (I330M/I311M)
4. Insert both end reflectors, ensuring that they both seat fully and evenly. The
replacement end reflectors must be installed before the new RF Gasket.
5. Install the two pre-cut (long) RF gaskets into the grooves for the end reflectors.
Insert one end flush with the top of the mounting surfaces (Figure 34). Working
toward the other end of the groove, press the gasket strip down firmly with the
thumbnail so that it rests at the bottom of the groove.
6. If you detect evidence of arcing on the back side of the reflector caused by the
RF gasket assemblies behind the reflector, then replace the two RF gasket
assemblies. Replace as described in “Replacing the RF Gasket Assembly” on
page 99.
CAUTION: Do not use the flathead screws to pull the reflector into place.
Excessive pull on these screws will deform the reflector face at its bend
radius or loosen its rivets. This would result in a failure of the screen
assembly to seat properly and subsequent damage to the screen gaskets.
IMPORTANT: The dichroic reflector and the R350 reflector do not have a
plastic protective cover on the reflector surface. The dichroic reflector has
a dark purple reflective coating. Do not attempt to remove the purple
reflective coating.
