16 STARTING

Before starting up check whether the mains power supply voltage corresponds with the information stated on
the probe's nameplate.

If there is a built-in ball valve you should also check, if it is closed. In case of hand-operated ball valves, the control
grip must be located at the right-hand stop.

Switch on mains power supply.

Check the rated value setting on the built-in thermostat or on the external controller.

The total heating-up time is approximately 2 hours. After about 1 hour the probe is already sufficiently heated
for the temperature to have exceeded the temperature failure alarm value (30 °C below rated value), but it still
takes about another hour until operating temperature is reached.
