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
working ‘life’ of the unit.
Using the Basket will allow a ‘Gentle’ cavitaon cleaning acon.
Suspending items in the tank without using the basket will allow a much more
vigorous cleaning acon BUT do not allow any item to rest on the oor of the tank as
this can cause transducer damage.

Model Tank Capacity Cleaning Power Heang Power Frequency
2L 1500ml 60w 100w 40 kHz
3.2L 2500ml 120w 200w 40 kHz
4.5L 3500ml 180w 300w 40 kHz
Ultrasonic cleaning is based on the cavitaon eect cause by high frequency ultrasonic
wave vibraon in the uid. Microscopic bubbles are formed, and they implode violently
causing the cavitaon which creates an intense scrubbing acon on the surface of the item
being cleaned. The bubbles are small enough to penetrate microscopic crevices, cleaning
them thoroughly and consistently.
Ultrasonic cleaning is an extremely eecve way of removing dirt and grime which would
normally require a longer cleaning period by hand. Small areas are easily cleaned with
Ultrasonic cleaning. It can be used to clean a wide variety of instruments and mechanical
parts, returning them to a bright clean condion without damage.
