ü To clean the inner and outer pump riser tube:
ü Please note: The parts coming into contact with solder can be cleaned more
easily as long as they are still hot!
a) Clean the pump riser tube (1) with a silicone brush.
b) Carefully heat the scoop for the riser tube (2) in the solder bath.
c) Insert the scoop for the riser tube (2) into the outer pump riser tube (3) in the
solder bath and carefully move it up and down.

Fig.156: Cleaning the solder surface
a) Remove any solder dross from the entire solder surface (1) with the solder
scraper (2) or a silicone scraper.
b) Collect the solder dross in a corner of the solder pot.
ð Please note: Work carefully and exerting little pressure to avoid damaging
coated surfaces!
c) Carefully clean the area around the coding pins (5).
d) Carefully clean the contact points of the coding pins and pressure chamber.
ð Please note: This cleaning process is particularly important. The area
around the contact points must be free of oxides and solder dross. Adher-
ent soiling can lead to leaks later on, after installation of the nozzle plate!
e) Use a perforated scoop (6) to remove the solder dross (7).
ð The process has now been completed.
