Instruments

Any deposits such as dental cement, composite, polishing paste or
similar must be removed immediately after examination of the patient,
e.g with a swab, before it hardens.
Instruments with particularly complex functional ends or very
stubborn deposits may require ultrasonic pre-treatment.
 To avoid injury from double-ended instruments or upright
instruments with upward-facing probes, the washer-disinfector
should be loaded from rear to front, and unloaded from front to
rear.
After thermal disinfection, manual secondary cleaning can be
undertaken according to relevant bio-substance regulations without
danger of infection, although the process must be monitored as
necessary.

Transmission instruments

Transmission instruments with light guide rods can be regarded as
durable, whereas fibre optic bundles can be susceptible to more
rapid wear.
Use a neutral to mildly alkaline liquid cleaning agent for cleaning.
Where there is build-up of deposits, a citric acid-based neutralising
agent should be dispensed.
The wash fluid must be filtered prior to internal cleaning so that the
narrow channels in transmission instruments do not become blocked
with treatment residues from the wash fluid. The injector basket A
105/1 should therefore be used for reprocessing transmission
instruments, in conjunction with the re-usable tubular filter A 800 and
the holder for transmission instruments
A 803 or the holder AUF 1.
The injector basket, tubular filter and the holder AUF 1 each come
with their own operating instructions.
After reprocessing, the insides of the transmission instruments must

be dried with sterile compressed air before being cleaned and
sterilised as appropriate in accordance with the manufacturer's
instructions. Please observe national regulations.
Before using transmission instruments again following
reprocessing, a function check must be carried out, e.g. by
spraying into a basin, to ensure they are clear.
 UK only: This washer-disinfector is NOT intended for
reprocessing transmission instruments such as turbines, hand-
pieces and contra-angles.
