6. Release the heated lid by lifting the latch forward
and use it to lift the lid. To close the lid, lower the lid
onto the block and press the latch to secure in
place.
7. Place the samples in the block. If individual tubes or
strip tubes are being used, space these out evenly
across the block to equalise the pressure from the
heated lid.
8. The heated lid has a rotating knob to adjust the lid
pressure on the samples, allowing for a variety of
consumables to be used. To adjust the pressure:
a. Place the samples in the block and place the lid
in the down position.
b. Adjust the orange rotating knob anticlockwise to
give the least pressure then close the lid fully.
c. Gently rotate the knob clockwise until you can
feel pressure beginning to be applied.
d. Rotate the knob a further quarter of a turn and
this will give the correct pressure. Do not over-
tighten.
9. Once the pressure has been set it does not need to be adjusted unless a different consumable is
used.
