This appendix provides information about removing and installing an IsoPlane 81 
grating.

C.1

Grating Carrier Replacement Procedure

Perform the following procedure to replace an IsoPlane 81 Grating Carrier:

1.

Loosen the four hand-tight screws securing the Grating Housing Cover to the 
IsoPlane 81 chassis. See Figure C-1.
