Chapter 4 Startup and Shutdown

4.4 Check at startup

Check the following items at startup of the unit.

When any abnormality is found, press the [OFF] switch immediately to stop the unit and turn the main power supply off.

zNo leak from circulating fluid piping

zNo circulating fluid flowing out of the overflow outlet and tank drain port

zCirculating fluid pressure within the specified range

„Bypass valve

Normally, the bypass valve is fully opened. If the unit is started up with the valve fully closed, circulating fluid supply may reach abnormal high pressure depending on external piping conditions. Be sure to keep the bypass valve fully opened for initial startup of the unit installed.

Adjust the bypass valve to obtain required pressure and flow rate by checking on the external pressure gauge and flow meter that can be prepared by customer or mounted on external piping.
