Pure water with a resistivity of not more than 4.5 MΩ/cm (0.22 μS/cm or more) can be
used as the circulating fluid.
Circulating fluid wetted materials
Stainless (Include heat exchanger brazing),
PTFE, PU,POM, FKM, EPDM, PVC, NBR
⚫ Confirm that the fluid level is between “HIGH” and “LOW” levels of the
fluid level gauge. If it exceeds the specified level, the circulating fluid
Be sure to connect the piping from the overflow port to the drainage
