Power Up

Follow these steps to turn on the unit to prepare it for use:

Set the power switch to the ON position. The
unit will go through a power-on self test that will
take several seconds. During this time the dis-
play will show the unitʼs capacity in liters.
2.
When the unit has completed its self-test, it will
maintain the bath at the last setpoint tempera-
ture. The Heat indicator will light when the unit is
applying heat to the bath. This indicator will
cycle on and off during normal operation.
3.
When the display shows normal operation after
completing the self-test, continue by setting the
temperature setpoint and backup temperature.
4.
If the display shows any message after complet-
ing the self-test, do not use the unit. Refer to the
Troubleshooting section to determine what is
causing the message to appear on the display.
