ü Skim solder until the baffle plate (1) becomes visible above the pump riser
tube.
ü Suitable receptacles should be provided on a heat-resistant base.
a) Carefully use the scoop included in the ERSA cleaning set to skim solder off the
solder pot into the receptacle provided for this purpose, until the baffle plate
(1) of the pump riser tube is above the solder surface.
ð Risk of accident! Fill the scoop only halfway with liquid solder in order to
prevent any liquid solder from spilling or splashing!
ð Risk of accident! Fill the appropriate receptacles with liquid solder slowly
so as to prevent spilling or splashing.
b) Let the skimmed solder cool until it is completely solidified. Keep the scooped-
out solder ready for being poured in again.
c) Clean the baffle plate of the pump riser tube (1) with a silicone brush.
ð The process has now been completed.
