Acid-Copper Electroplating Module Model 1000 Manual
Getting things ready - Draining I

Draining and purging the system

Totally draining the tank and all of the associated plumbing consists of a number of steps that must be performed in the proper sequence if all of the leaching solution (or electrolyte) is to be removed. Using the air assisted purging facility it is possible to remove virtually all of the leachant from the system. Only about ½ liter will remain, which can be flushed out with deionized water prior to filling the tank with plating solution (electrolyte)


Draining tank into carboy
Figure 7

  1. Put on your acid proof smock and gloves and a facemask (or a pair of safety glasses with full side shields).
  2. Have enough plastic 5 gal. (20 liter) containers to hold all of the leaching solution. The solution can be stored indefinitely for later use (in the event of system contamination) or CAREFULLY neutralized using sodium carbonate and disposed of.
  3. Remove the drain line cap, and hang the outlet into the first container (fig. 7). OPEN the drain.
  4. Rotate the pump valve to the DRAIN position (fig.6) and turn the main power on. The pump will drain the tank much faster, but you must monitor the level of liquid in the container that you are filling. As the level nears the top, turn OFF the drain valve and then quickly rotate the pump valve handle to the RECIRCULATE position (fig.6).
