operation
19 Switch on the filtration pump with the Start key.
Cleaning solution is drawn in through the intake line until it flows into the
bottle at the open line end. Leave the filtration pump switched on until
the minimum quantity (see
 128) has been drawn in from the container
with cleaning solution.
If necessary, increase the percent setting for the pump performance at
the filtration pump.
20 Switch off the filtration pump with the Stop key; allow the cleaning solu-
tion to take effect (altogether approx. 10 min). During this time, occa-
sionally start/stop the filtration pump so the cleaning solution in the
intake line is moved towards the bottle.
21 When doing so, check the filling level of the bottle to keep the solution
from overflowing. If necessary, empty the bottle (dispose of the cleaning
solution properly).
22 Switch off the filtration pump with the Stop key.
23 Reconnect the intake line to the filter module and reinstall the filter mod-
ule in the sample.
24 Switch on the filtration pump with the Start key and let it pump for some
time (at least 5 - 10 min, depending on the length of the intake line) with
approx. 60% capacity to completely remove all the cleaning solution
from the filter plate and intake line. This can normally be recognized by
the clear sample liquid that comes out of the line. If necessary, set the
percent setting for the pump capacity to the previous value.
25 Switch off the filtration pump with the Stop key.
26 Reinstall the overflow vessel in the Alyza IQ.
27 Mount the sample overflow tube to the collection funnel for the sample
overflow.
28 Screw the sample feed tube to the overflow vessel.
29 Re-connect the sample tube to the overflow vessel.
30 Remove the container that held the cleaning solution. Dispose of the
remainders of the cleaning liquid properly.
31 Switch on the filtration pump with the Start key.
32 Leave the filtration pump to work for some time to completely remove
the detergents.
