Auto fluid-fill function
Open the fluid supply valve that is connected to the automatic fluid-fill port
by the customer.
Fluid supply will be started and stopped automatically by the ball tap in the
tank.

Check the drain port is closed by the valve to prevent the supplied
circulating fluid from draining out.
z
When the circulating fluid temperature set and/or the ambient
temperature is lower than 10 deg. C, use 15% aqueous solution of
ethylene glycol. Otherwise it may cause icing of the fluid
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.

If 15% ethylene glycol aqueous solution is used, dilute pure
ethylene glycol with water. Additives such as antiseptics cannot
be used.
