Think and act in a safe manner. Always disconnect power and use a lockout before you work on the E-coat system, or any of the related subsystems. Observe any confined space conditions. Use the appropriate safety equipment and clothing for the task. Please carefully read all the instructions listed below to familiarize yourself with the project before attempting to perform any of the work.
- Teflon Tape
- 17 mm (11/16”) open end wrench for 12.7 mm (1/2”) Return Tubing
- 22 mm (7/8”) open wrench for (3/4”) Return Tubing
Before you operate your Membrane Shell it needs to have the Overflow Nozzle installed first. In most cases the Overflow Tubing size is 12.7 mm (1/2”) by 17.5 mm (11/16”) and the OD of the Overflow Nozzle Hose barb is 15.9 mm (5/8”) NOTE: With the larger hose barb, a hose clamp is not required.
If the Membrane Shell is very long (usually with an effective length of 2900 mm (114.2”), then the larger Overflow Nozzle should be used. Therefore, the Return Tubing size is 19.1 mm (3/4”) by 25.4 mm (1”) and the Overflow Nozzle Hose barb is 19.1 mm (3/4”). Even in this case a hose clamp is generally not required.
In either case, the actual Overflow Nozzle has male National Pipe Threads (NPT) on one end and a hose barb on the other end.
Find the Overflow Nozzles in a separate bag. If the threads do not have TEFLON tape, then apply tape as required.
Remove the Membrane Shell from the carton or crate taking care not to damage it.
Engage the threaded end of the Overflow Nozzle into the female thread boss in the Neck of the Membrane Shell. This boss is usually about 150 mm (6”) from the top of the Membrane Shell. Tighten with the wrench.
As an alternate method, the Membrane Shell can be installed in the ED tank first. Use a deep well socket instead of the wrench.
