8.2 Bath Cleaning

To clean the instrument’s exterior, which
includes all painted surfaces and glass, either
a solution of soap and water or laboratory
grade detergent may be used.

Apply cleaner to clean wipe or cloth, not to the
instrument directly. Wipe surface clean.

Do Not clean bath exterior with organic
chemicals such as Acetone, Toluene, Hexane,
etc.

For more difficult cleaning of finished surfaces,
a dilute solution or isopropanol in water may
be used.

It is not recommended that more aggressive
solvents be used on painted surfaces since
paint color will tarnish or be stripped from the
instrument.

Stainless Steel surfaces, such as on the top
plate, may be cleaned using a more
aggressive solvent such as a stainless steel
cleaner.

Glass surfaces may be cleaned using a more
aggressive solvent such as acetone, if
necessary.
SHOCK AND BURN HAZARD: Only clean
inside the bath when equipment is de-energized
and unplugged from the mains power supply.
Allow adequate time for heating coils to completely
cool before cleaning.
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.
