4 INSTALLATION
4.1 Important
Tamson Instruments b.v. 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 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.
4.3 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 packaging 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 which should be
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.

4.4 Placement and ventilation
Air circulation has to be enabled by 10 cm of free
space at both sides and 15 to 20 cm at the rear of
the bath.
The bath has to be placed in a well ventilated area.

Airflow
Air must pass the apparatus freely. The air transports
the heat from inside the apparatus to the environment.
When airflow is blocked the apparatus will not perform
to its specifications and it may harm the equipment or
even cause mechanical damage.
Dust
Do not place the bath in a dusty environment. Dust will
block the condenser unit inside the apparatus which will
lead to severe mechanical damage.
Regularly check the apparatus and condenser unit
for dust. Remove dust with a vacuum cleaner. Do
NOT remove dust with compressed air.
Leaking
Inside the bath the cold parts condensate and ice can
be build. When the apparatus is switched-off this melt
water may leak onto the floor. Do not place the
apparatus on a floor which can be damaged by this melt
water. The amount of water is limited to a few mL/hr.
4.5 Initial use
Due to transportation allow the bath a 24 hour
period for stabilization. This applies also when the
apparatus has been tilted or fallen.
Do not switch on power, because lubrication-oil inside
the compressor system has to run into the capillary.
It will take several hours before the oil has flown back
into the compressor unit. When the apparatus is
immediately turned on after it has been tilted, severe
damage may occur to the compressor unit due to
insufficient lubrication.

4.6 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. 3 mm²/s) at the operating
temperature and a flash point which is well above
the operating temperature.
The best bath liquid to be used is methanol,
enabling circulation at very low temperatures.
Methanol is extremely flammable and can cause fire
hazard. Take all necessary precautions to reduce fire
hazard.
When using methanol all vapors must be removed by
using appropriate air ventilation.
Methanol is toxic and can cause health risks. Use
appropriate ventilation and other precautions to prevent
inhaling toxic vapors. If ventilation is insufficient the risk
of explosion hazards can occur!
The supplier of the bath liquid (methanol) will be able to
hand over all chemical details and safety precautions
related to the use of methanol. These precautions must
be followed when operating the bath.

Extreme HAZARD
Do not use methanol at temperatures above 20°C.
The methanol will vaporise and cause toxic and
flammable vapours. Explosion hazard can build up
in or around the bath
When working at temperatures above 20°C, oil or
water can be used as an alternative.
Water, water-glycol, mineral or silicone oil also are
liquids applicable to use in this bath.
Do not use distilled water. Distilled water can cause
corrosion to the stainless steel inner bath and its
parts. Filtered water from reversed osmoses
apparatus can be used without problem.
4.7 Bath fluid level
4.7.1 Minimum level
The minimum fluid level is just above the baffle plate.
When fluid level is lower than the baffle plate circulation
will be insufficient causing instability and non
homogeneousness of the fluid temperature .
The level indicator on the front panel will start to blink
(blue light) when the fluid level is too low.
Minimum level:
1 cm above
