Before filling the bath remove any remaining
packing material from its interior. The interior of the
bath can be accessed by taking off the lid on the top
of the bath.
4.3 Bath liquids
The bath must be filled with a liquid suitable for the
minimum operating temperature.
It is very important to select a liquid with a viscosity
preferably less (e.g. 10 cSt) at the operating
temperature and a flash point which is well above
the operating temperature.
The use of other liquids is allowed as long as the
viscosity of the fluid is low enough at the operating
temperature. Following products can not be used as
bath fluid:
- Distilled water,
- Aggressive fluids when in contact with stainless
steel 304, 316, glass or PTFE and silicon
sealing.
The fluid flash point must be well above the maximum
operating temperature.
When the bath has been installed it must be filled
with an appropriate liquid. When working with water
the bath should be filled to 1 cm below the lid. For
oil the bath should be filled to not more than 5 cm
below the lid. Depending on the operating
temperature the liquid level in the bath should be
observed and excessive fluid should be removed.
The liquid level should be maintained between 1 and 3
cm below the lid during normal operation.
A lower level than 5 cm below the lid may damage the
heaters. A high bath level can cause overflow and might
also damage the bath insulation.

The oil used has a limited lifetime.
The type brand and operating temperature mainly
determines lifetime. Spilling of sample may also reduce
lifetime and in some cases can start chemical reactions.
Silicon oil has the tendency to form gel, for this reason
silicon oil has to be replaced as soon as visible changes
like string forming are noticed. Within a few hours silicon
oil can transform itself into solid gel, which is very
difficult to remove. When not totally cleaned, very small
pieces of left over gel will catalyse new oil to form gel!
Do not use distilled water. This will cause corrosion
and wear of stirrer bearings.
Only use water as a bath fluid below 80°C/175°F.
Working for a longer period with water at
temperatures above 80°C will damage the stirrer
bearings.
When working at temperatures below 10°C / 50°F
ethylene-glycol should be added to the water. For
example, in the volume proportion of 50 / 50%.

Using the bath for long periods at low temperatures
will cause condensation on the glass window.
When operating at high temperatures the lid (of the
bath) top plate and the window section of the bath
become very hot. Always use heat protective
gloves. Care must be taken when placing or re-
moving material from the bath.
Pay attention when removing hot fluid:

Use proper ventilation
Heated bath fluids can cause toxic fumes.
Remove fumes from hot oil or bath medium. Use
fume cabinet or proper air ventilation.
When changing the bath fluid from water to oil for
operating at temperatures above 80°C, completely
remove all the water from the bath. Small drops of water
may result in hazardous situations while reheating the
bath with oil.
Water and oil must at all times be kept separate
within the bath. Never mix oil and water in or around
the bath.
Do not spill water in hot oil.

Never empty hot oil into a plastic container.
4.3.1 Maximum level
If the fluid level is too high, it will leave the bath via the
overflow outlet (14mm or 3/8" outher diameter pipe, no
thread). Prevent fluid from the overflow outlet entering
the side of the bath. For this reason the overflow outlet
must be connected to a waste container.
When the bath is working at high temperatures, tubing
and waste container must be chemical resistant and
able to withstand high temperatures (>230°C / 446°F).
4.3.2 Drain bath liquid
The bath can be emptied via the drain tap located at the
backside of the apparatus. For safety reasons the tap
can only be opened by using a screwdriver. The thread
inside the tap is 3/8".
Take necessary precautions against fire hazard
when removing flamable bath fluid.
When removing bath fluid do not inhale toxic vapor.
Always use appropriate ventilation.
Handle old bath fluid as toxic waste.
Cool down bath fluid to ambient before removing.

4.4 Cooling
The bath is provided with an integral cooling coil.
Because of the friction-heat generated by the stirrer
mechanism the bath will heat-up slowly. The lowest
operating temperature at which the bath can be
controlled depends on the fluid used and the ambient
temperature. When operating at lower temperatures it
will be necessary to pass cooling liquid from a cooling
circulator (TLC10 or TLC15) or tap water through the
cooling coil. As an example to operate at 40°C / 104°F
with an ambient temperature of 21°C / 70 °F and a
cooling water temperature of approx. 16°C / 60.8°F an
amount of 100 to 200 ml/min. is sufficient for a stable
control of the bath temperature.
When the applied applied power (which is displayed on
the LCD) exceeds 8%, stable control and adequate
response time is realized.
4.5 Connecting
Before plugging the bath into mains socket, make sure
the voltage of the bath corresponds to the local voltage.
Use a mains supply that is well earthed, clean of
interference and suitable for the acquired electrical
load of the bath.

5 GENERAL
The TV-series is intended for temperature control of
applications requiring a high degree of stability over a
broad temperature range. The robust construction
including advanced safety features give the bath a
range of wide application.
The heat input is controlled by a microprocessor system.
A special optimized electronic temperature
measurement circuit ensures an extremely high degree
of accuracy and reproducibility of operation conditions.
The baths feature a standard RS232C interface for
communication with a computer. Please download our
free communication software "Tamcom" from the
website.
The baths standard features include an integrated
cooling coil enabling for rapid reduction of its
temperature or alternatively enabling control around or
slightly below ambient temperature.
5.1 Construction
The TAMSON baths are constructed entirely from
corrosion-resistant materials such as stainless steel and
PTFE (Teflon).
A thick layer of rock wool between the inner bath and
outer casing ensure effective insulation. It improves
temperature stability and lowers the casing temperature
when the instrument is used at high bath temperatures.
The central microprocessor within the control module
manages and controls, the functions for temperature
measuring regulation, program storage, safety control
and error coding.
5.2 Temperature control and setting
The bath temperature is regulated using a PT100
temperature probe which is connected to a
microprocessor module. The advanced electronic
control system continually computes the energy input
required for optimal temperature accuracy and stability.
The controller will activate the heaters partially or in full,
taking into account the difference between actual bath
temperature and set point.
The required temperature is set by three membrane
switches on the front panel. Read-out is on LCD. An
absolute temperature offset is provided with a resolution
of 0.01°C (0.001°C for the TV4000MKIIDC) and a
specific offset of 0.005°C is available from the menu.

This fine-tuning can be carried out at any time during
operation of the bath.
5.3 RS232C Control
A RS232C, bi-directional communication interface (300
to 38400 Baud) is integrated as standard, and offers the
possibility of computerised control.
5.4 Safety systems
A number of precautions is provided to ensure a safe
around the clock working of the bath. These features
protect the equipment, the bath fluid temperature and
the workplace. A mechanical over-temperature
protection thermostat (1) will automatically switch-off the
entire bath when its maximum value is exceeded. This
maximum temperature can be manually adjusted from
50°C up to 270°C.
A thermal protection of the stirrer mechanism (13) will
switch off the motor in case of malfunction. Both
thermostat and motor-fuse can easily be accessed. A
large number of integral electronic safety checks will
cause the bath to shut-down in case of electronic or
electrical error (11). Any kind of activated safety system
will be attended with an acoustic and visible alarm. On
the front display operating faults or component failures,
are reported as numbered ’errors’. In this way there is a
continual check of the proper functioning of the bath.

6.2 Safety thermostat
When the bath temperature becomes higher than the
set point temperature of the safety thermostat. The
heating electronics and controller are switched-off. The
red LED on the display will light. When the temperature
of the bath has been lowered with approximately 20°K,
the thermostat re-sets itself automatically, however to
continue normal operation the bath has to be switched
off and on again.
When switching off wait 5 seconds before switching
on again.
