Amendment 1 Closed-Loop Rinsing Unit
This description supplements the operating instructions for the conveyorized etching machine DL 500 to
the aspects of installing and operating the closed-loop rinsing module. This text cannot replace profes -
sional literature and safety discussions on the issue of waste water treatment, though.
Setup
The module is designed for installation behind the DL500 and under the delivery table of the etching
machine DL 500. You can also place the rinsing tank at any other place near the machine, as long as both
Installation
Tubes and connectors that are necessary to connect tank
with the rinsing section of the DL500 are part of delivery.
Water inlet into the machine is a 3/4” thread connection. At
the tank there is a vertical 20mm spout.
The water flows back from the machine via a 30mm inner
diameter tube.
The remaining valve at the tank serves to drain the water
from the tank with the help of the pump.
The cover of the rinse module canbe remove to allow control
of water quality or to add chemicals such as flocculants or
similar.
Connect the power cable of the tank to the plug underneath
the DL500
The tank can take up 30l. There is a small nozzle at the drain
of the tank sticking a little up. This is done by purpose to
provide room for sedimentation underneath the drain of the tank. The pump is not suitable for dry run.
Make sure that this nozzle is always covered with water !
The pump switches on, when the etching pump of the DL500 starts running. The amount of rinsing wa -
ter can be adjusted by the ball valve underneath the DL500. Normally leave the valve completely open
when using a rinsing tank.
Amendment 2 Stripper
This description supplements the operating instructions
for DL 500 for the special version DL500-S Stripper.
Divergent of the standard DL500 the stripper version
comes with an additional lateral filter basket to filter out
possibly residues from the stripping process. The
machine also has a bright, alkali-resistant tooth belt. The
stripper version is filled instead of the etchant with
special stripping liquid. The approach for negative
tenting resist is about 50g stripping chemical on one liter
of water.
Please pay heed to the following points:
Check regularly the sieve in the side tank of the
machine, so that the stripping agent does not overflow.
