7.4.3.3 Replacement
• Lift Top Cover P/N 173568 off Side panels (P/N 173557 & 173559). Top Cover,
Side panels and H-bars P/N 173607 fit snugly into place together. H-bars may
remain on Side panels or on Top Cover.
• Remove Front panel P/N 173615 by unscrewing 4 Screws P/N 420560.
Hint: Front panel may be used as screw holding place for further actions.
• Side panels are removed by unscrewing 8 Screws P/N 420560 (currently 2
screws per panel, front and rear).
Hint: If no more uncovering is needed, do not remove side panel’s lower screw at
the back since there are matching indents to join the side panel with the back
panel.
• Unscrew the 2 remaining screws and remove Back panel P/N 173609 and Panel
P/N 173555 in the rear.
Hint: If it is all right for the Back panel to remain on the Pipetting Arm, do not
remove lowest screws since there are indents in Panel to join it with back panel.
Covering:
• Instructions are the reverse of those for uncovering. Ensure shadow gaps and
collision-free mounting for Pipetting Channels and X-Movement of Pipetting Arm.
• Join Panel and Back panel at the rear and place screws loosely in Back panel -
do not tighten them yet.
• Join Side panels to Back panel and fix them with screws.
• Reassemble Front Panel with 4 screws.
• Tighten all screws.
• Snap Top Cover onto H-bars and Side panels.
