If the test result is
negative
Hollow instruments must be tested within the frame-
work of quality assurance tests.
Residual water must be expelled from hollow instruments using
medical compressed air. This procedure also verifies that lumen are
clear.
The pH value of displaced water can be checked using litmus paper
(grade ≤ 0.5). The pH value should lie between 5 and 8.
In the event of a blockage or reduced clearance, remove the offend-
ing particles or blockage manually.
Then, even if the pH value is neutral:
Reprocess the hollow instruments.
If the pH is still not neutral after reprocessing, contact Miele to ar-
range for further analysis of the problem.
Cleaning the A 800 tubular filter
The tubular filter must be cleaned at least once a week.
Follow the cleaning instructions in the operating instructions for the
tubular filter.
Test point for measuring water pressure
The connection at the front is used as the test point for measuring
water pressure. This connection point can be used for testing pres-
sure within the framework of performance and validation testing in
accordance with EN ISO 15883.
To measure water pressure replace the blind stopper with a Luer-
Lock adapter, e.g. E 447.
