Maintenance

6.8. Tube Replacement

6.8.1

Replace the Pump Tubes

The pump tube [D] of the peristaltic pump is exposed to a minimal

wear. It is therefore recommended to exchange the pump tube annu

ally.

CAUTION
Pollution of reagents possible.

If the occlusion frames are opened during operation, already

mixed reagents will flow back into the reagent canisters and pol

lute the reagents.



Never open the occlusion frames if the instrument is in opera

tion.



Proceed according to

Stop of Operation for Maintenance, p. 42

before opening the occlusion frames.

Overview

Pump housing

Occlusion frame closed
