A collection of wires runs from the lower
control panel up the left side, while looking
at the back of the bath. Halfway up the
wiring are three points where the wires can
be disconnected. See Figure 4 below:
Figure 4. Wiring Disconnection Point

There are a total of three joints to
disconnect. First disconnect the single large
cluster of wires by pressing in the sides of
the lower plastic piece then pulling the top
plastic piece.

Then disconnect the two smaller joints. Each
side of the joint is labeled with an identical
number one (1) or number two (2). This
makes for easy connection when re-
assembling the instrument.

Once the wiring is completely disassembled
it is safe to remove the top assembly of the
bath.

Remove the six screws lining the two sides
of the top assembly with a Philips head
screw driver.

Make sure there is sufficient space with
cleaning clothes to place the top assembly
when lifted off the bath.

Lift the top assembly with one hand on the
back side and one hand on the front side of
the top assembly. Place top plate assembly
on flat surface with the back side of the top
plate assembly and the heating coils on the
surface.
15.
With the top plate assembly now removed
from the main instrument it is now easy to
access the inside of the bath jar for further
cleaning.
16.
With the top assembly resting on its back, it
is now possible to clean the heating coils,
stirrer blade and rod and other components
that have been in contact with the bath
medium during operation.

Once the bath jar and top assembly are
clean and dry, re-assemble the instrument
and fill the bath with new medium as per
section 5.1 of this document.
