Acid-Copper Electroplating Module Model 1000 Manual
Getting things ready - Unpacking III

Drain valve closed
Figure 5
  1. Because of the wide variation in air supply systems, you will have to supply your own coupling to connect the air line to a source of CLEAN, DRY compressed air. The unit is provided with 10 ft. of ¼ in. polyethylene tubing with a compression style connector already installed.
  2. If you are using shop air (air compressor feeding a storage tank), you must use a filter to insure that the air stream is free of dust, dirt and oily aerosols. Attach the air tube to your air supply through a filtered regulator fitted with a needle valve to control the volume of sparging air. Position a "master shut-off" valve between the pressure regulator and the needle valve. This valve will be very useful when purging the return lines when changing the solution filter as well as for controlling the air supply during daily operation.
  3. If you are using a regenerative blower as a dedicated source of compressed air for your plater, the air valve should be preceded by a "by-pass" valve. With this setup you will increase bath agitation by slowly closing the by-pass valve until the desired degree of bath turbulence is achieved. This will maximize the amount of air flowing through the compressor, letting it run cooler and more efficiently.
  4. Before proceeding make sure that the drain valve is closed and the PVC cap is screwed into place at the end of the drain hose. Although no fluid can leak from the system unless the pump valve (see fig.2 & fig.6) is in the drain position, it is better to be safe than sorry.
