Cleaning with the ultrasonic machine
The UR1 is suitable for cleaning of analysis sieves up to 215 mm in
diameter, and the UR2 up to 450 mm diameter.
In each cleaning operation, ensure that the material to be cleaned is
completely covered by the cleaning and contact fluid.
Fill the vibratory trough to at least 2/3 capacity with
cleaning/contact fluid, with 5 - 10% ”TICKOPUR RW77” cleaning
fluid, available as an accessory, added.
Place the material to be cleaned in the perforated basket available
as an accessory, with the dirtier side facing downwards.
Insert the perforated basket.
Switch the ultrasonic cleaner on.
Fill the vibratory trough to at least 2/3 capacity with fluid, e.g.
TICKOPUR RW 77, which is available as an accessory.
No fluid, or too low a level, can lead to damage to the machine.
Do not stack the material to be cleaned.
The ultrasonic waves are otherwise absorbed.
Fragile parts must not touch each other.
Parts may otherwise be damaged.
Ensure that no air bubbles can form in cavities.
Cleaning will otherwise not be sufficient.
Do not place any parts directly in the vibratory trough or on its base.
The machine could be damaged.
No liability is accepted for damage to machines or instruments caused
by the use of unsuitable cleaning or contact fluid.
Do not use flammable liquids such as petrol or acetone, or chemicals
which contain or split off halogen ions as the contact fluid.
!
Do not reach into the cleaning fluid during ultrasonic cleaning.
