Cover Assembly
The cover assembly contains the blue plastic outer lid, white painted
metal lid liner, hinge springs (2), hinge rod, and latch striker. Early
models had a fixed (non adjustable) striker. The adjustable striker
can be installed using kit no. 50782A (ventilated) or 50782B (RF
models). The striker may require adjustment if a Lid warning appears
frequently.
Strike Adjustment
To adjust the cover latch striker:
1. Loosen the locking nut that holds it in place.
2. Adjust the striker by screwing it up or down, to correct its height
for locking.
3. Be sure to lock it back into place by tightening the locking nut with
a wrench. This will prevent it from loosening when the unit is in
operation.
A properly adjusted cover will result in no Lid warning and no air
leakage around the sides and front of the cover. If this adjustment
does not resolve the Lid message, latch switch adjustment may be
required. To check the latch switch alignment, refer to Section 8.4.
Most service to the unit requires the removal of the cover (lid)
and cabinet, as described in the following procedures.
Cover Removal
To remove the cover assembly:
1. Open the cover and unplug the centrifuge.
2. Remove (4) Phillips head screws which attach blue lid to lid liner.
3. Remove the blue lid, while supporting the lid liner.
4. With lid liner raised to remove pressure from the hinge springs,
remove spring arms from the cutouts in the lid liner bracket.
5. Remove hinge rod by sliding to the right or left, and remove
springs and lid liner.
Note - the two hinge springs are not identical, and can only be
properly installed one way.
