3.5 Circulating Fluid Supply
3.5.1 Automatic water 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. 3-19 Fluid level gauge
Confirm that the fluid level is between “HIGH” and “LOW” level of the
fluid level gauge.
Be sure to connect the piping from the overflow port to the drainage
pit to drain excessive amount of the fluid from the tank.
When the ambient temperature or circulating fluid temperature is
10
o
C or below, refer to "3.2.2 Operation at low ambient
temperature or low circulating fluid temperature". Tap water may
be frozen in the thermo-chiller which may damage the product.
Confirm that the valve of the drain port is closed to prevent the
supplied circulating fluid from draining out.
Fluid level displayed range
When clear water is used, refer to “7.1 Quality Control of
Circulating Fluid and Facility Water”.
When ethylene glycol aqueous solution is used, dilute pure
ethylene glycol with water. Refer to "3.2.2 Operation at low
ambient temperature or low circulating fluid temperature" for the
concentration of the ethylene glycol aqueous solution. Additives
such as antiseptics cannot be used.
When deionized water is used, the conductivity should be 1 μS/cm
or higher (Electrical resistivity: 1 MΩ・cm or lower).
