4 INSTALLATION
4.1 Important
Tamson Instruments bv is not responsible for any
consequential damage or harm caused by using this
bath. Repairs on the electrical system of the bath may
only be carried out by well trained and authorized
persons.
4.2 Unpacking
Before leaving the factory Tamson baths are adequately
packed to prevent damage during normal transportation.
Check the packing for external damage and make a note
on the shipping documents if any damage is found.
Always retain the cartons and packing material until the
bath has been tested and found in good condition.
(Transport companies generally will not honor a claim for
damage if the respective packing material is not available
for examination).
The shipment contains at least the bath as mentioned in
the delivery checklist. Further the consignment might
contain one or more viscometers, individually packed in
small boxes with the calibration certificate included in the
box, as well as ASTM thermometers, thermometer
holders etc. Please see the packing list for details
concerning total contents of consignment.
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.
2.1 Tilting
Before unpacking inspect the tilt watch located on the
outside of the packing. When the tilt watch indicates a red
color contact Tamson instruments and the forwarder
before continuing with unpacking.
2.2 Ventilation
The bath has to be placed in a well ventilated area. Air
circulation has to be enabled by 30 cm of free space at
all sides.
If the bath has no or insufficient ventilation severe
mechanical damage will occur.

3 Bath Liquid
The bath must be filled with a liquid suitable for the
minimum operating temperature.
The bath must be filled with a liquid suitable for the
minimum operating temperature.
It is important to select a liquid with a viscosity of
less than 10 mm²/s.
When using flammable bath liquid choose a flash
point 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.
The viscosity must be below 10 mm²/s. High viscosity will
result in poor stability as well as poor uniformity of the
bath.
The fluid flash point must be well above the maximum
operating temperature. Fluid must not be aggressive
when in contact with stainless steel, brass, glass and
silicon sealing.
!! Extreme HAZARD !!
Do not use methanol at temperatures above 20°C.
The methanol will evaporate and cause toxic and
flammable vapors. Explosion hazard can build up in
or around the bath.
When working at temperatures above 20°C, water or
oil can be used as an alternative.
* Do not use ethanol. Ethanol often contains high level of
water. Water will freeze inside the bath and leads to
cooling and stability problems.
Do not use the water mixtures at temperatures where
the mixture can start to freeze. Frozen bath fluid can
severely damage the bath and stirrer mechanism.
Commercial enterprises specialized in refrigeration
may supply alternatives for mentioned circulation or
bath fluids. These alternatives can be less toxic or
flammable. However in most cases they are very
corrosive to copper, brass and aluminum, etc.
Heated bath fluid can cause toxic fumes. Take
precautions and read material safety sheet if applicable.
Remove fumes from hot oil or bath medium. Use fume

If the fluid level becomes too low and the heating
elements cannot fully dissipate their power, these
elements may reach a temperature above the ignition
point. It is possible that the bath liquid ignites under these
conditions.
The heating element must be fully covered by the
bath fluid. The heating element will be damaged when
not fully submerged in the bath fluid.
3.1 Drain bath fluid
The TV12LT can be emptied via the drain tap located at
the backside of the apparatus. For safety reasons the tap
can only be opened when using a screwdriver. The
thread inside the tap is 3/8".
Take necessary precautions against fire hazard when
removing flammable bath fluid.
When removing bath fluid do not inhale toxic vapor.
Always use appropriate ventilation.
Handle old bath fluid as toxic waste.
Bath fluid must be at ambient temperature before
removing.

3.2 Bath fluid level
Minimum level
The heating element must be fully covered by the bath
fluid. The heating element will be damaged when not fully
submerged in the bath fluid.
The practical minimum level is indicated below.
The level indicator (optional) will start to blink (blue light)
when the fluid level is too low.

Maximum level
If the fluid level is too high, it will leave the bath via the
overflow outlet (14mm outer diameter pipe). Prevent fluid
from the overflow outlet entering the backside of the
TV12LT. 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 (>150°C / 302°F).
3.3 Safety and protection
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 heat protective clothing and wear gloves and safety
glasses:
remove all the water from the bath. Small drops of water
may result in hazardous situations when reheating the
bath with oil.
Never mix oil and water in or around the bath.
3.4 Cooling
The bath is provided with integral cooling system. The
cooling is split in two functions.
When cooling down to the set point temperature
maximum cooling capacity is used.
Whe the set point temperature is reached the bath will
start to tune for stable control. It also switches the cooling
in a low power mode.
The surplus of cooling is heated away. This way a very
accurate set point temperature is maintained.
By using this two stage system only limited cooling
capacity is heated away. This saves an enormous
amount of energy when comparing energy consumption
with competition. It also offers much more precise
temperature control.
