2. Set the circulating fluid temperature. When you press the "ENT" key, the set temperature (lower
part of numerical value display: green) flashes. Press the [▲] [▼] key to set the target
temperature, then press the "ENT" key to set.
(Flashing ends when set.) Please refer to various setting / display.
3. Press and hold [RUN / STOP] key for 1 second. The [RUN] lamp lights up and operation starts.
When you operate for the first time after piping, the circulating fluid in the tank decreases until
the circulating fluid is filled in the piping. (An alarm occurs when the liquid level falls below
"LOW".) When the circulating fluid in the tank decreases, repeat "Circulating liquid supply"
procedure so that the liquid level is within the range from LOW to HIGH. 30 seconds after start
of operation, if the circulating fluid flow rate is less than 3 L / min, an alarm occurs and the
product stops. Ensure that the circulating fluid flow rate will be 3 L / min or more.
When using option T (high head pump specification), if the circulating fluid discharge pressure
becomes 0.5 MPa or more, an alarm occurs and this product stops. Refer to "4.3 Adjustment of
bypass valve" and make it to 0.5 MPa or less.
