CLEANING
If the surface is still hot, contact with liquid
may create steam that can scald you.
It is important to allow the instrument
to cool before cleaning.
CLEANING OF MINOR SURFACE SPILLS
Turn off the system and disconnect the block from
the
Digi
PREP
controller. Allow the block to cool.
Sponge up any excess liquid, dilute the area with
clean water, and wipe dry with a paper towel.
CLEANING OF DIGESTION WELLS
Turn off the system and disconnect the system
from the block controller. Allow the block to cool
before proceeding further.
Suction the solution out of the well(s) with an
eye dropper, squeeze bottle, or pipette. Dilute any
remaining spillage with water, two or three times,
and suction as much solution out as possible.
Sponge the remaining residue with a paper towel.
Allow the system to dry completely before
plugging into a power outlet. Observe good labatory
practices by wearing gloves to preform the above
task.
CLEANING MELTED PLASTIC FROM WELLS
Heat the block to 160°C. Using a pair of
needle-nose pliers, carefully pinch and gently
pull the softened plastic residue from inside the
well. If it is diffi cult to remove the melted plastic
increase the block temperature by 5°C.
CLEANING OF A MAJOR SPILL
If a solution has run down below the white top
ring and under the block, turn off the system and
unplug the block
from the power source. Allow
the block to cool before proceeding further.
The block must be disassembled, cleaned, and
thoroughly dried prior to running again.
Please consult the service
department for help if required.
In order to access the block, you must fi rst remove
the white top ring. This step will be different depending
on the model of your
Digi
PREP
block. To determine
the model of your block, fi rst turn the unit onto its
side and check the bottom for an aluminium key.
1 . If your Digi
PREP
block has an aluminium key:
Insert the aluminium key into one of the slots
located on the bottom of the unit beside the rubber
feet. Gently push the aluminium key into the slot
until the white top ring begins to lift. Repeat the
process for the three remaining slots, and
return the aluminium key to the base of the unit.
(If the aluminium key is missing, a substitution
such as a fl at-head screwdriver may also work.)
2. If your Digi
PREP
block does not have an
aluminium key:
The white top ring is held in place by plastic spring
clips inside the housing at all four corners. Release
the clips by gently lifting the corners of the white top
ring until it becomes free. If it does not remove easily,
insert a fl at-blade screwdriver between the white
top ring and the outer Kydex skin. Gently twist the
screwdriver to pry the white top ring off at all
four corners.
Next, use tweezers or pliers to gently remove
the insulation from the sides of the block. (If
a replacement set of insulation is required,
contact the service department.)
The graphite block is held into place by four
mounting bolts located on the bottom of the unit.
Turn the unit upside-down onto a soft surface, being
careful not to scratch the Tefl on coating on the
graphiteblock. Using a fl at-blade screwdriver, remove
the plastic cover plates. Next, using an Allen wrench
(6mm or ¼ inch), remove the mounting bolts. Finally,
lift the housing up from around the graphite block. (Lift
gently as there is wiring attached to the graphite block.)
You may now clean any affected parts with
a damp cloth. Gloves and a lab coat are strongly
recommended. (Be careful not to pinch the wires
between the graphite block and other components.)
To assemble repeat in reverse order.
Before reassembling, make sure that the Tefl on
sheet is adhered to the block, that the heater is
secured in place, and that the aluminium plate
is placed over the insulation. Also ensure that all
components are dry prior to reassembling.
