IMPORTANT…
The unit is fitted with a ‘Cavitation Heating System’.
This means that whilst the unit does not use a conventional heating element
the circuitry that operates transducer has been designed to create strong
cavitation and therefore heat the cleaning fluid.
In order to try and prevent excessive fluid temperature the unit will ‘pulse’
when it reaches approximately 50
o
C.
This feature is not intended to prevent coagulation of proteins in dental
applications. Separate monitoring should be used for this purpose.
This pulsing is not detrimental to the unit, however, if it is important to you
that you don’t clean items in higher temperatures you should turn the unit
off and either replace the cleaning fluid or allow the unit to cool. If the unit
is allowed to pulse for prolonged periods the temperature will continue to
increase well above 50
o
C and could eventually result in the self-resetting
thermal cut out operating. Should this protection device operate the Green
Neon on the front of the unit will remain illuminated, however, no ultrasonic
agitation will be heard. If this should occur, unplug the unit and allow it to
cool. The unit will self-reset within 5 minutes.
A transducer overload device also protects the unit. This device may
occasionally operate during normal use. It can be identified by an occasional
‘pulse’ during a normal cycle. This indicates that an incorrect solution is
being used, the fluid level is incorrect or the transducer is self-protecting.
Water alone will not respond to ultrasonic energy when it contains dissolved
gas or contaminants. Water drawn from the main will contain a quantity of
dissolved gas. Fresh water/solution should ALWAYS be ‘de-gassed’ by
operating the ultrasonic unit containing the fresh water, basket and cleaning
solution for 6 minutes. After degassing avoid unnecessary agitation of the
fluid as this will introduce air. ALWAYS replace the fluid when contaminated.
