8.
Delicate items should be cleaned in a basket to reduce the ultrasonic intensity and turn the
basket periodically during the cleaning cycle to stop standing wave cleaning hotspots.
All single frequency ultrasonic cleaners create standing waves where the cleaning effect is most
aggressive, between these hotspots the ultrasonic intensity will reduce. A more even clean is
achieved by using the "pulse" function (see page 10) and by periodically moving the item being
cleaned or turning the basket several times during the cleaning cycle.
PLEASE NOTE; the use of a basket will reduce the cleaning effectiveness, for this reason, it
is preferable to suspend heavily soiled robust items so they are exposed to the full ultrasonic
intensity. Items must not sit on the base of the bath.
9. Always use warm water, never hot/boiling. If using an aqueous solvent you can speed up the
heating of the fluid by mixing some preheated water with the room temperature fluid in the bath
and fitting the lid which also reduces evaporation. Do not thermally shock the bath by putting
boiling water directly into an empty bath.
Refer to fluid manual for operating temperatures.
10.
Make sure there is good space around your objects, it is not advised to overlap items in the tank.
The more items loaded into an ultrasonic cleaner the longer the required cycle time will be to
effectively clean them so it is better to wash little and often.
If you are cleaning a small part in a large ultrasonic cleaner you can reduce solution wastage by
11.
using only a small amount of cleaning solution in a vessel containing the item being cleaned and
fill the rest of the bath with plain tap water.
Print heads should be considered delicate. It is advisable to soak the print head first to loosen
12.
dried ink, run the ultrasonic in cycles of two minutes then flush head with warm water and see if it
runs clear. Long cycle times can cause the head to fail or lead to imprecise ink dispensing.
Due to the nature of rubber and certain soft materials, the cleaning action is reduced as the
13.
cavitation action is bounced off the material's surface.
