REPAIR AND REPLACEMENT
SIDE PANEL ASSEMBLIES
The non-acoustic and acoustic side panels are illustrated in figures 3-20 and 3-21 respectively. All work on the side pan-els requires that the drive be accessible on all sides.
Perform the up-down adjustment to cause the top of the side panel to be parallel and flush with the top of the cabinet frame. Perform the front-back adjustment to cause the front edge of the side panel to be parallel to~ and approximately 40 rom (1-1/2 in) in front of the front cabinet frame member
(see figure 2-22). For this adjustment also ensure that front edge of side panel is flush with the front door when it is
installed. Perform the in-out adjustment to cause the acoustic seals on the side panel to be in contact with the cabinet
frame. This adjustment should be snug enough to cause a slight squashing of the seals when the side panel is secured in place.
A complete side panel adjustment is performed in the following order:
1. Adjust lower two brackets on side panel until panel meets up-down adjustment requirements.
2. Adjust lower two brackets on frame until panel meets front-back and in-out adjustment requirements. Lower rear bracket on frame governs exact front-back placement, while lower front bracket needs only an approximate
placement.
3. Adjust top two brackets on frame so that 1/4-turn fasten-ers line up with side panel in front-back direction and that side panel meets in-out requirements.
4. Adjust top two brackets on side panel so that they line up with 1/4-turn fasteners.

Removal and replacement procedures for the side panel assem-blies depend on the style of the cabinet: non-acoustic or

removal.
The following procedures describe side panel
Replacement is accomplished in the reverse order of
Non-Acoustic Side Panel - Remove side panel as follows:
1. Open front door and remove ground cable(s) from side pan-el(s) by pUlling cable from quick-disconnect.
2. Remove front attaching hardware from side panel(s).
3. Open rear door and remove rear attaching hardware while supporting side panel(s).
4. Lift side panel up to clear side panel brackets.
Acoustic Side Panel - Remove side panel as follows:
1. Open rear door and remove ground cable from side panel(s) by removing screw and lock washer.
2. Release rear 1/4-turn fastener(s).
3. Open front door (or fully extend lower drive on its
slides) and release front 1/4-turn fastener(s) while sup-porting side panel.
4. Lift side panel up to clear side panel brackets.
Repair
Side panel repair i t limited to replacing broken or damaged parts. Section 3 lists all field replaceable parts of the side panels. There are no special tools required for side panel re-pair.
The only special material required is sprayable adhesive. This is used in attaching the acoustical foam panels to acoustic side panels. Procedure for using the adhesive is the same as that listed under case assembly repair.
SLIDE ASSEMBLIES
The slide assembly relationship to the drive and frame is il-lustrated in figures 3-4 through 3-6. Identification of the various slide parts is shown in figure 2-23.

Re moval-Replace ment
The following procedures (with differences noted) apply to all drive configurations which use slide assemblies.
Removal - Remove slide assembly as follows:
1. Pull drive out to its fully extended position by pressing full extension releases.
2. Disconnect I/O cables, power cable, and system ground.
3. Loosen nuts securing quick-disconnect catches and slide catches toward front of drive.
CAUTION
Two people are required to lift drive off slide assemblies.
4. Carefully l i f t drive (with quick disconnects attached to drives base assembly) from slide assemblies and set on a solid support.
5. Remove quick disconnects from drives base assembly by re-moving attaching screws and washers.
6. Push slide assemblies to fully closed position by press-ing in full extension releases and pushpress-ing in slide as-semblies.
7. Loosen mounting hardware securing slide assemblies to frame.
8. Disengage slide assemblies from frame by pUlling slotted ends of slides out from between nut plate and frame.
Replacement - Install slide assemblies as follows:
1. Loosen adjusting screws and adjusting nuts on slide as-semblies such that rear recess bracket can slide back and forth.
2. Push slide assemblies into fully closed position.
3. Loosely attach screws, lock washers, and nut plates to frame. Leave hardware loose enough so that slotted ends of slide assembly can be inserted between nut plate and
frame.
4. Adjust position of rear recess bracket such that slide assemblies can be positioned in frame. position slide
assemblies in frame with quick disconnect flanges at bot-tom and facing one another.
5. Tighten mounting hardware securing slide assemblies to frame. Tighten adjusting screws and adjusting nuts se-curing rear recess bracket to main bracket.
6. Ensure that slide assemblies are aligned both horizontal-ly and verticalhorizontal-ly by pressing full extension releases.
7. Pull both slide assemblies to their fully extended posi~
tion by pressing full extension releases.
8. Separate quick disconnects from slide assemblies by loos-ening nuts securing quick disconnect catch and sliding catch forward.
9. Remove rubber mounting pads from bottom of drive (some units may not have mounting pads).
NOTE
For ease of assembly and to prevent damage to case assembly, remove case before installing drive on slide assemblies.
10. Using four countersunk flat-head screws and countersunk washers on each side, attach quick disconnects to drives base assembly.
CAVTION
Before mounting drive ensure that all slide assembly mounting hardware is secure. Use two people to lift drive on to slides. When in-stalling drawer mounted drive, use care not to exert undue downward pressure or frame may tip forward.
11. Carefully l i f t drive over fully extended slide assem-blies. Engage mounting tooth on quick disconnects with mounting slot on outer slide. Ensure that mounting block
is properly seated in mounting notch.
12. Slide quick disconnect catch into position uner outer slide and tighten nuts.
13. Press in to release full extension locks and then slide drive in and out several times to ensure that it slides

freely and that binding does not occur. If binding oc-curs, slide assemblies are not properly aligned.
14. Connect I/O cables, power cable, and system ground.
15. When slide installation is complete, install side panels (drawer mounted drives only) and then install case assem-bly.
