Chapter 5 Display and setting of various functions
This function can be activated only when the power supply is ON
and the thermo-chiller is not operating.
Fully open the valve or manual bypass valve that is arranged by the
user to make it possible for the circulating fluid to circulate when
the pump starts automatic operation.
In extremely cold weather, the heat generated by the pump
operation may not be enough to prevent freezing of the circulating
fluid.
During the automatic operation, the pump does not stop even if the
"RUN/STOP" button is pressed. To stop the pump, turn the power
supply OFF or turn this function OFF.
This function does not prevent the automatic water fill circuit from
being frozen. Countermeasures against freezing of the automatic
water fill circuit should be taken with the user's equipment.
