3.5 Circulating Fluid Supply
3.5.1 Automatic fluid-fill function
Open the fluid supply valve that is connected to the automatic water fill port.
Fluid supply starts and stops automatically with the ball tap in the tank.
Fig. 3-20 Fluid level gauge
z Confirm that the fluid level is between “HIGH” and “LOW” level of the
fluid level gauge.
z Be sure to connect the piping from the overflow port to the sump pit
to drain the excessive amount of the fluid from the tank.
When the set circulating fluid temperature and/or the ambient
temperature is lower than 10 deg. C, use a 15% aqueous solution of
ethylene glycol. Tap water may be frozen in the thermo-chiller which
may damage the product.
z Confirm that the valve of the drain port is closed to prevent the
supplied circulating fluid from draining out.

z When tap water is used, refer to “7.1Quality Control of Circulating
Fluid and Facility Water”.
z When 15% ethylene glycol aqueous solution is used, dilute pure
ethylene glycol with water. Additives such as antiseptics cannot
be used.
z When deionized water is used, the conductivity should be 1 μ S/cm
or higher (Electrical resistivity: 1M Ω
･
cm or lower).
