z
Do not use tap water or hard water. Use of these waters can cause
the internal pump failure and the performance deterioration by
generation of scale.
z
High concentration (more than 50%) ethylene glycol can cause
temperature control error or system failure.
z
Attention should be taken on water quality. Ensure water quality is
within specified range, and other foreign materials contaminate the
bath liquid. Potential temperature control error, cooling error or
system failure may occur if disregarded.
