fluid discharge temp.".
Remove any causes of the
problems.
1. Check the external piping.
Check if the external piping is in the conditions shown below:
(1) The system has a circuit that high temperature circulating fluid returns to the Thermo-Chiller at
once due to an operation of the valve or the switching valve in the external piping.
(2) The system has a circuit that the circulating fluid that has been heated by a waste heat of the
workpiece that is cooled returns to the Thermo-Chiller at once when the Thermo-Chiller starts
operation.
