MAINTENANCE
WARNING
Before performing any maintenance on this unit, be
sure to disconnect electric power.
This unit utilizes high voltage to operate the
ultrasonic transducers. Only qualified
trained personnel should attempt any
repairs or servicing of the ultrasonic
components.
Several routine maintenance procedures
should be followed to enhance the
performance of the equipment and to ensure
long term reliability.
U LTRASONIC G ENERATOR
The ultrasonic generators have fans to cool the
electronic components. These fans may
become blocked with lint or debris that will
inhibit the free flow of air. Periodically (every 1
to 3 months) under normal conditions, the
generator
intake grill/screen should be
inspected (for debris build-up), cleaned and
placed back into the housing. Access to the
generators is via a screen inside the underside
of the machine. Should it be necessary to
remove the ultrasonic generator there are
several connections from the generator to the
system. If any connections are disconnected
be sure all connections are re-connected prior
to restarting the machine. Only a qualified
technician should perform this maintenance.
The ultrasonic generator utilizes high voltage.
While the unit is out of the housing, the
electronics can be visually inspected to
determine any areas of abnormality
(discoloration etc.). At this time, any build-up of
dust or debris on the electronics should be
gently brushed off or removed by using a
gentle blast of air.
G ENERAL C LEANING
To prevent build-up of contamination on tank
walls, it is advisable to periodically drain the
tank solution and wash out the tank.
Be careful when cleaning the ultrasonic tank to
not scratch or abrade the ultrasonic radiating
surface, as this will reduce the life of the
radiating surface.
