► Attach the fluid feeding pipe.
► Check the levelling of the tip cleaning base plate– if required adjust it using the screws.
► Check the baths overflow level (see chapter 8.2.1 "Checking and adjustment the bath overflow
level" [}64]).
► Close the access door.
8.2.1 Checking and adjustment the bath overflow level
A successful nozzle tip cleaning process requires the nozzle tip to dip into the cleaning agent
without overflowing the liquid. Therefor the seat sleeves (see 8.2 "Changing a tip cleaning mod-
ule" [}63]) should be filled up just below the upper edge (~1mm).
To check the bath overflow level please proceed as follows:
► Start the device in the manual mode (password required).
► Select the tip cleaning module to be adjusted.
► Select the cleaning module.
► Start the pump until either the required maximal fluid level is exceeded (the liquid should stay
within the sleeves) or the overflow level is reached.
► If the overflow level has been reached and the maximal fluid level is within the range the out-
flow is adjusted well. If not the overflow level needs to be adjusted.
► Open the drain valve to drain the module.
► If the overflow level is not reached or the maximal fluid level is not the range the overflow level
needs to be adjusted.
► In case of not reaching the overflow level at exceeded maximal fluid level or reaching the
overflow level below the recommended fluid level the level height adjustment is necessary. In
order to do so disassemble the inspection window (gasket state assessment) of the cell and:
– If the maximal fluid level has been exceeded you should slowly screw the overflow head in
until the fluid surface in the sleeves drops to the required level (~1mm/rev.).
– If the fluid level has been set below the required level the overflow head should be un-
screwed to the fluid recommended level (~1mm/rev.);
