3.6 Option J Piping of
【
Automatic fluid filling
】
Automatic fluid filling port and over flow port need to be connected when
optional [automatic fluid filling] is selected.

Piping to automatic fluid filling port
Connect the piping to supply the circulating fluid. Automatic fluid filling is performed by using
the solenoid valve which is built in the thermo-chiller.

Piping to the overflow port
This is necessary when automatic fluid filling function is used. Discharge excess circulating
fluid when the fluid level in the tank rises due to the failure of the solenoid valve etc.

Piping should be within f19 of I.D. and 5m of length.
Riser piping (trapping area) should be avoided.


Supplying fluid from the automatic fluid filling port
Fluid filling starts if the power supply is turned ON when the fluid level of the circulating fluid
is “L” of the level indicator or lower (P XX). Fluid supply stops when the fluid level reaches
the proper level. If the fluid level does not reach the proper level in an hour after starting
supplying fluid, it causes the alarm “AL01; Low level in tank". Fluid supply continues while
the alarm is generated. Fluid supply stops after the fluid level reaching proper level. Alarm
continues after fluid supply is completed. Release the alarm referring Chapter 7.
