When the required temperature is reached the heater will turn o. If ultrasonic mode is
sll on, the temperature may rise slowly unl the ultrasonic cycle is complete, this is due
to addional heat from the transducers - it will be aected by the amount of material being
cleaned.
At the end of the cycle turn the machine o and allow a period of 5-10 minutes before
using again. The maximum period for the Usonic cycle is 60 minutes. This prolongs the
