corresponding program place.  
When a coded mobile unit is inserted in  
the machine and the door closes, the  
automatic mobile unit recognition  
selects the assigned program. Be sure  
no small items connect to the magnetic  
strip.  
^ Each mobile unit must be coded  
before being used for the first time.  
See "Mobile unit coding".  
^ The wash program through which the  
mobile unit is coded has to be  
assigned to the relevant program  
place.  
^ Press 6 to start the program.  
Program place changes, see the  
"System function - Selector switch  
organization" section in the  
Programming Manual.  
Important!  
Before starting the program with the  
"Start" button 6, check that the  
program needed for this mobile unit  
is displayed.  
The coding is made up of 5 bits:  
– Bits 1 to 4 define the mobile unit  
code,  
Otherwise insufficient wash results  
may occur!  
– Bit 5 serves as a control (Parity-Bit).  
Always check that programs for  
mobile units with AWK (on fixed  
program places) are not exchanged.  
Bit 6 controls the volume of water intake  
and the circulation pump for mobile  
units with side coupling. This setting  
cannot be changed!  
Mobile units without side coupling are  
coded with tracks which do not contain  
Bit 6!

Make sure that you code mobile  
units with side coupling to a track  
where Bit 6 is set to I.  
Mobile units without side coupling  
must be coded with a track that  
does not have Bit 6.  
The magnetic strips on the G 7825 /  
G 7826 must have gray magnets.  
The magnetic strips on the G 7827 /  
G 7828 must have black magnets.  
^ Put the magnetic strip back in the  
track.  
Important:  
The magnetic strip must be placed  
in the track so that the Bit coding,  
set according to the chart, is visible  
through the round windows of the  
track.

Application  
The machine can be fitted with a variety Check before cleaning  
of mobile units, baskets and inserts,  
depending on the cleaning application  
desired.  
– Are the items to clean correctly  
sorted, loaded and connected?  
– Are the spray arms clean and can  
they rotate freely?  
– Is the filter combination free of  
coarse soiling? Clean if necessary.  
– Is the adapter to the water inlet in  
place? The spray arms correctly  
connected?  
– Are the detergent and neutralizer  
containers full?  
Check after cleaning  
– Check the cleaning results visually.  
– Perform protein analytical checks,  
e.g. with the Miele test kit.  
– Are the jets and connections  
securely connected with the mobile  
unit / inserts?  
19  
 
Application  
Loading tips  
^ Tall, narrow pieces should be placed  
in the center of the baskets. This  
ensures good water coverage.  
Select mobile units, baskets and  
inserts appropriate for the  
application.  
^ Mobile units with an adapter must  
engage correctly.  
^ Load the items to be washed so that  
water can access all surfaces. This  
ensures that they will be properly  
cleaned.  
^ Engage inserts correctly into the  
module carts.  
^ The spray arms must not be blocked  
by tall items or items which hang  
down in their path. If necessary,  
manually rotate the arms to test.  
^ Do not place items to be cleaned  
inside other pieces where they may  
be concealed.  
^ Petri dishes and the similar should be  
placed in the correct insert with the  
soiled side facing the center.  
^ Hollow vessels such as beakers,  
measuring cylinders, flasks, etc.  
should be inverted and placed in the  
correct inserts so that water can flow  
in and out unrestricted. A cover net  
can be used to reduce the risk of  
movement during the wash process.
