Note 1) Differs depending on operating conditions.
Note 2) Determined under the following conditions: water as the Bath liquid, set temperature 25
°C, Facility
Water temperature 25
°C, flow rate 3L/min, ambient temperature 25°C, and sealed from outside air
with a lid.
Note 3) An appropriate range is from 3 to 7L/min. To prevent damage to the facility water circuit on this
product, do not supply a flow over the maximum flow rate of 8L/min.
Note 4) When the temperature is set high, the liquid temperature inside of the liquid bath and the
temperature inside of the thermostat could differ greatly depending on the heating mode at
start-up, and the thermostat could then begin operating and stop the output.
Note 5)
1. Do not use the thermo electric bath under the condition where the bath liquid splashes or
leaks out. Otherwise, peripheral equipment as well as the thermo electric bath can break.
2. When the set temperature is increased from a low value to an ordinary value, some kinds of the
bath liquid can swell, increase and overflow, which can not only break the thermo electric bath
and other equipment, but also cause a serious accident. Take a measure to prevent this
situation in advance by decreasing the amount of the bath liquid, etc.
