Ultrasound cleaning:
The ultrasound cleaning is to prefer to
mechanical cleaning. This is especially
true for the sensitive instruments used for
endoscopies.
• Instruments must be completely
immersed in cleaning solution.
• Instruments must be cleaned for at least 3
minutes at a frequency of 35 KHz.
• Instruments can be rinsed either
mechanically or by hand but rinsing must
be thorough and if possible with desalinated
water.
• Follow the manufacture’s instructions for
the ultrasonic unit.
• After cleaning instrument parts must be
clean to visual inspection. After cleaning
parts must be sufficiently dried.
4.4 Care of valve
After cleaning and drying, all moveable parts
such as the rotation adaptor and joints must
be treated with an appropriate preservation
based on paraffin oil.
Warning! The rotation adapter and sliding
surface of the piston must be greased with
our special care lubricant. (Art. No. 26905-
00)
