3-2.2. Completing a System Test Routine
After arranging the equipment described in Section 3-2.1, complete this System Test
Routine which describes what switches to press and the changes to observe.
ALARM NOTE: If power is removed from the unit without actuating the power switch
(I/O switch) a power fail alarm is activated and the LED located on the front panel of
the unit flashes. To stop alarm, restore power to the unit and push the SILENCE ALARM
button.
ALARM NOTE: If at any time the water falls below the minimum level, the LO WATER
LED is activated and the alarm sounds. The unit shuts down and the operator cannot
proceed until this is corrected by filling the reservoir.

5. A beeper sounds.
6. The seven segment display flashes the set point temperature 42°C for a few
seconds and the unit begins to pump and heat the water.
7. The seven segment display will show the actual water temperature.
8. The HEAT LED will light up if the water temperature is less than 42°C/107.6°F.
