“H” mark on the fluid level indicator. Use tap water which satisfies the water
quality standard shown inTable 7-1, or a 15% aqueous solution of ethylene
glycol.

When a 15% aqueous solution of ethylene glycol is used, prepare the ethylene glycol aqueous
solution separately.
To control the concentration of the ethylene glycol aqueous solution, a concentration meter is available
separately from SMC.

Liquid level
Check the drain port is plugged or closed by the valve to prevent the
supplied circulating fluid from draining out.
Supply the circulating fluid up to the “H” mark on the tank.
If the liquid level in the tank becomes lower than the "L" level or the
circulating fluid flow becomes 4L/min or less, the thermo chiller stops
operation.
