8.3 Draining / Changing Bath Medium
WARNING: Do not begin draining the bath
medium until it has reached ambient
temperature.
NOTE: When a decision is made to discard this
material, dispose of this material and its
container to a hazardous of special waste
collection point. Country, State, or local laws
may impose additional regulatory requirements
regarding disposal. Dispose in accordance to all
applicable regulations.
1. Remove one of the seven port covers from
the top plate of the bath.
2. Insert a siphoning tube into the port opening
and lower tube to bottom of glass bath jar.
3. Apply a reduced pressure to the opposite
end of the tube with a pump or withdrawal
bulb.
NOTE:
Be sure the discharging end of the
tube is below the surface of the bath
reservoir.
4. Remove the withdrawal bulb or suction
pump from the end of the tube and allow the
bath medium to drain into a lower reservoir
or receptacle.
5. Once the bath fluid is drained from the bath,
it is time to remove the complete top
assembly of the bath.
6. Using a flat head screwdriver, remove the
four (4) silver screws located at the four
corners of the back panel.
7. Remove the back panel plate and set aside.
8. 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
9. 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.
10. 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.
11. Once the wiring is completely disassembled
it is safe to remove the top assembly of the
bath.
12. Remove the six screws lining the two sides
of the top assembly with a Philips head
screw driver.
13. Make sure there is sufficient space with
cleaning clothes to place the top assembly
when lifted off the bath.
14. 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,
