The upper MSD cover is removed for venting and for many maintenance proce-
dures. The lower MSD cover is removed to check the fluid level in the diffusion
pump and for a few maintenance procedures. If you need to remove one of the
MSD covers, follow these procedures:
Upper MSD cover
1 Grasp the front of the upper MSD cover and lift up enough to disengage
the front latch.
2 Reach back and grasp the back edge of the upper MSD cover.
3 Pull forward to disengage the spring latch.
It may take a firm pull to disengage the latch.
To reinstall the upper MSD cover, reverse these steps.
Lower MSD cover
1 Remove the upper MSD cover.
2 Remove the 3 screws that hold the lower MSD cover in place.
3 Move the cover left slightly to disengage it and then pull it straight
forward.
To reinstall the lower MSD cover, reverse these steps.
