4.3 Preparation of circulating fluid
Circulating fluid is supplied only inside of the product at the time of installation of the
thermo-chiller.
When the product starts operation in this condition, circulating fluid level will be reduced
as the fluid in the level gauge goes down due to the fluid supply to the user's equipment
from the thermo-chiller, and the additional fluid needs to be supplied to the
thermo-chiller.
Follow the instructions below to supply additional fluid:

Press the [PUMP] button on the operation panel (press the [RUN/STOP] button and [MENU]
button simultaneously).
The pump operates independently while the [PUMP] button is being pressed. The [RUN] light
(green) blinks while the pump is operating independently and the circulating fluid in the tank is
supplied to the user’s equipment and piping. This finds out leakage from the piping as well as
discharges air from the piping. If the fluid level in the tank reaches the lower limit, a buzzer will
be generated, and the alarm number “AL01 (low level in tank)” is displayed as PV on the digital
display. The [ALARM] light (red) blinks, the [ ] light turns ON, and independent operation of
the pump stops. For alarm reset, refer to step 2.

the individual operation of the pump and fix the leaking part.
